Dr. Kevin Quinlan, President of Delphi Powertrain Business Unit Asia Pacific Region and Delphi's Global Head of Fuel Supply and Evaporative Control Products Business Unit at an Open Technical Seminar
Ladies and gentlemen, everyone!
I am very happy to have the opportunity to discuss the alternative energy of the power propulsion system with everyone. This issue is not only closely related to everyone present, but also an industry issue that I have actively participated in and deeply attracted by Delphi.
Today's discussion on alternative energy sources for the power propulsion system can be said to be in time and place.
Why do you think that is the best time of day? Because consumers are increasingly concerned about the cost, environmental impact and sustainable development of the transport system, the Chinese government is taking the lead to take measures to actively respond.
The Chinese government launched a target of using 5% of the total market sales of autos with alternative energy sources by 2011. To ensure that this goal is achieved, consumers will receive a certain subsidy when buying green cars, and car manufacturers will also receive government funds to help develop new technologies.
Let us take a step back for a moment to understand the current market trend. We can see that green environmental protection has become an overall trend, and this global trend has a huge impact on the market and will continue to heat up. Now that I say this is based on reason, it is because Delphi has always paid close attention to it and has actively participated in this trend.
Of course, the fierce debate surrounding this issue has not been conclusive and is expected to continue. Today, let me discuss this issue from the point of view that is most relevant to you here.
There are three major factors contributing to the "green solution" dispute: the first is the environment; the second is the limited nature of oil prices and petroleum resources; the third is the economy.
As consumers, we are concerned not only with the issue of fuel prices; we are also concerned about the problem of how long gasoline fuels are now commonly used. At the same time, the issue of global warming is also our concern.
As the debate between consumers over which alternative energy solution should be adopted is heating up, we also find that governments of various countries try to use different legal requirements to quell their internal disputes caused by economic factors. Different approaches to the "green" problem often lead to conflicts. As a result, suppliers are at a loss as to what kind of solutions can one really do? And how can I maintain a competitive advantage in the global market in the future?
Of course, the problems we face now are very complicated. Since calling it complex, it means that we need different solutions - of course, each solution involves different technical means. This is exactly what the suppliers need. They need to provide a variety of technologies to ensure their dominance in the future market.
Therefore, the focus of our discussion today is on alternative energy power plants. I hope everyone can think about green issues from different perspectives.
In my opinion, whether it is to solve short-term or long-term energy problems, we all need to consider different existing solutions so that we can truly meet the needs of consumers.
The automotive industry is now seriously considering these solutions. They can be mainly attributed to three broad categories of standard technologies: internal combustion engine technology including spark ignition engines and compression ignition engines, hybrid and battery electric powertrain system technologies, and the latest fuel cell technologies. I will detail the details of these technologies in more detail later.
The rapid development of several technologies mentioned above has played an important role in helping automakers significantly reduce their emissions. At the same time, high-efficiency air-conditioning compressors, lightweight components, and harness systems are also seen as important means of mitigating the carbon impact of modern automobiles.
In addition to stand-alone technologies, car manufacturers and suppliers have also developed a variety of hybrid and electric vehicle technologies, ranging from miniature hybrid parking-start systems to plug-in hybrid and all-electric vehicles. .
At Delphi, we strive to lead the development and application of technology throughout the industry. In order to introduce these technologies into China and to work with customers to select the most suitable solution, Delphi has made arduous efforts. The goal of our efforts is to integrate these technologies into the current and future cars.
Meet different market needs with different hybrid solutions
As consumers' demand for hybrid vehicles continues to increase, and in order to achieve lower fuel consumption and carbon emissions than traditional internal combustion engine vehicles, I think it is necessary to first introduce to everyone the alternative energy sources in automotive applications. First of all, I would like to introduce you to the technologies and product lines used in hybrid vehicles. Then I will briefly mention the possible role of alternative fuels and fuel cells.
There are more than one type of hybrid. The charm of hybrid technology is that it can be tailored to different types of hybrid and electric vehicle applications. The hybrids we are talking about now actually contain a variety of different technologies that can provide manufacturers with numerous solutions. In general, hybrid technology generally includes four types from micro hybrid vehicles to plug-in hybrid vehicles or range-extended electric vehicles (micro, medium, full hybrid, PHEV (plug-in hybrid electric vehicles Serial-parallel full-hybrid vehicle adopting larger battery))/REV (span-extended electric vehicle (tandem hybrid vehicle)).

Hybrid and electric technology market direction
Since customer needs vary widely, it is important for a technology company to have the ability to cover all four types. As shown in the figure, everyone can see that there is a different demand for hybrid power in the market at the same time.
Having a clear and thorough understanding of hybrid technology has always been one of Delphi's areas of pride, because hybrid technology is complex and requires a full range of capabilities.
Because we have every part of our expertise, because we know how to effectively combine various technologies in different ways, so we can discuss with customers to determine what is the most suitable for their hybrid design, and how to solve it. The plan can truly meet their unique needs. Basically, all Delphi's hybrid and electric vehicle systems are completed in a standard modular design. It enables us to reuse modules as much as possible to reduce the cost of hybrid vehicles through economies of scale - from power electronics and energy management systems, to electronic/electrical architectures, heat exchange management technologies, to automotive aftermarket expertise No better.
We have established partnerships with a number of customers in China and other Asian countries and will launch new hybrid vehicles as early as next year. Now, let me give you an example of what is the most popular hybrid technology in the Chinese market. Considering factors such as cost and integration complexity (production items), micro- and mid-size hybrid vehicles will be the first to be launched. The plug-in electric vehicles and electric vehicles of most OEMs in China are still in the R&D stage.
Delphi has more than 20 years of experience in power electronics products and more than 70 years experience in automotive electronics products. Therefore, whether it is a miniature, medium-sized or large hybrid vehicle, Delphi can easily provide a variety of advanced technologies, especially the core of the battery system, hybrid control equipment, high voltage inverter, DC/DC converter, etc. part. At the same time, we also participated in the design and production of EV1 power equipment, control electronics, energy storage, and hybrid electric booster architectures for various models of General Motors. In addition to drastically reducing the electrification cost of hybrid electric vehicle drivetrains, Delphi has received more than 200 patents related to hybrid electric vehicles since 2000.
Not long ago, Delphi successfully integrated hybrid system control equipment, inverters, DC/DC converters, and lithium battery systems into a single module. The product is air-cooled and can be easily placed behind the rear seat of a passenger car. This unique embedded small and medium hybrid system is a complete drive system that can be used in a variety of voltage and power environments. In addition, the Delphi 12V parking/start system shuts down the engine when the engine is idle and quickly restarts the engine through the auxiliary belt, which significantly reduces vehicle fuel consumption. This system, combined with Delphi's engine management system, can significantly reduce fuel consumption and emissions. The product will be launched into the Chinese market in 2010, and will play an important role in improving vehicle emissions and noise pollution in cities with large traffic volumes such as Shanghai and Beijing.
Alternative fuels and fuel cells can also be an alternative green solution
Below, allow me to briefly introduce alternative fuels and fuel cells.
Here, I would like to give an example of the production of biofuels. In recent years, biofuel production has increased year by year. Original crops such as corn, sugar cane, vegetable oil, and the like are used for the production of biofuels. In the United States, for example, since the beginning of 2006, the growing area of ​​corn for biofuels in the United States has continued to grow – a significant portion of which has been used for ethanol production. In 2007, the amount of corn used for ethanol production has reached 25% of total production.
Of course, all sectors of the society have always had a dispute over the “heavy emphasis on food and fuel.†The arable land area on the earth has been extremely limited, and competition between the energy market and the food market will undoubtedly lead to rising food prices. In the United States, for example, even if all cereal products are used to produce biofuels, they can only meet 16% of the automotive fuel demand.
Now, all countries in the world have invested a lot of research and development forces to study how to produce second-generation biofuels from non-food crops, crop residues and waste. This method combines the cultivation of food with the cultivation of fuel raw materials while generating electricity.
On the other hand, fuel cells can be called the most unique alternative fuel technology because they generate electricity directly through fuel conversion. At present, many companies have already invested in the research and development of fuel cell technology. The driving force behind their R&D is that fuel cells have most of the advantages of a battery-powered powertrain system, but they are free from limitations such as driving distance and charging time. At the same time, the weight is also very light.
Delphi Corporation is one of the leading companies developing fuel cell technology. One of Delphi’s newest technologies, the Solid Oxygen Fuel Cell (SOFC) Auxiliary Power System (APU), is a highly efficient and environmentally friendly device that can directly convert the chemical energy of traditional automotive fuels such as gasoline, diesel, and biodiesel into useful ones. electricity. For commercial vehicles, Delphi's solid-state oxygen fuel cell auxiliary power system can help drivers meet increasingly stringent engine idling and emissions requirements and reduce overall fuel consumption.
It can be used as an example of the alternative energy currently being used, and it is also a model of alternative energy technologies combined with other energy sources.

Green Solution Status: Driveline Technology Makes Our Earth Greener
In addition to directly reducing fuel consumption, the entire automotive manufacturing industry has also developed other advanced technologies, especially in markets such as China. The focus of today's market is mainly on advanced technologies that several car manufacturers have begun to sell in global markets, but I would say that these current technological advances have helped car manufacturers achieve many great green goals:
They not only help automakers meet increasingly stringent emission standards, but also increase engine efficiency, reduce overall vehicle weight, and increase fuel efficiency. At the same time, they also effectively reduce emissions through technologies that can more effectively capture water vapor.
I would like to briefly introduce to you the major manufacturers and key technologies in the field of emission reduction and fuel economy in the current market. Delphi has leading technologies and solutions in these technologies and has worked with a number of OEMs and system manufacturers both at home and abroad.
Variable Valve Timing Technology (VVT)
The first thing to mention is the variable valve timing technique, abbreviated as VVT. This is a relatively young technology, but it has a greater impact on car manufacturers. It significantly reduces the fuel consumption of the car by improving the energy consumption technology. In the past three to four years, VVT technology has rapidly become widely used in the market, and it is almost unknown to become a technology adopted by 60% of cars on the market.
VVT technology not only gives us higher fuel efficiency, it also improves torque performance at low speeds, increases peak power, and reduces hydrocarbon emissions. The reason why this technology is rapidly becoming popular in such a short period of time is that its cost/benefit ratio is very high - it achieves an excellent balance between input and output. VVT technology also adjusts the balance between fuel economy, performance and emissions. It also brings more benefits in different applications.
Gasoline Direct Injection (GDI)
Another drive system solution that I will introduce here is GDI (Gas Direct Injection Technology). Homogeneous gasoline direct injection technology can achieve the best charge distribution, improve combustion efficiency, make fuel injection more accurate, the engine cleaner, thereby increasing engine power, reducing its size. Compared with conventional compression ignition technology, spray-stratified combustion gasoline direct injection can achieve significantly higher engine performance with significantly lower costs. It can also help manufacturers achieve future CO2 emission standards by increasing engine efficiency.
Oil and gas evaporation control system
In the field of oil and gas evaporative emission control, Delphi offers a range of oil vapor canister products to meet a variety of regulatory requirements, such as the Euro 4 standard, the United States Partial Zero Emission Vehicle (PZEV) standard, and vehicle-mounted oil and gas recovery systems (ORVR). Delphi is also committed to the development of new technologies to improve carbon canister desorption efficiency, such as active heated purge, desorption of hydrocarbon detection assisted EFI systems to improve fuel economy, and more. All of these technologies help reduce the evaporation of fuel oil vapors from fuel storage to engine fueling.
Diesel Common Rail System
Solutions for diesel engines include common rail systems, which can help manufacturers reduce emissions, increase fuel economy, and increase engine torque and power to meet customer demand for performance.
Small Engine EMS Solution
Another technology that has developed rapidly in China is the EMS solution for small engines. The electronic fuel injectors are designed for motorcycles, tractors, lawn mowers and other small applications. This technology can help small engine product manufacturers meet new emission standards.
The application of these powertrain systems and their future R&D are all focused on a need to achieve an optimal balance between meeting local consumer needs, local legal requirements and cost-effectiveness.
In today's market, in addition to the drive system solutions that satisfy consumers' needs for green fuel-efficient cars, there are other solutions that can make cars more environmentally friendly and fuel-efficient. Let us look at a few examples below.
We can optimize the electronic/electrical architecture to reduce its weight, so as to achieve the goal of reducing fuel consumption. Automation and miniaturization in the design and production of electrical and electronic products can improve the quality of electrical and electronic products while reducing the weight and overall size of the harness. At the same time, we can also achieve the same purpose by using lightweight materials such as aluminum wire. The use of halogen-free cables is a great benefit to the environment because it can be recycled and free of halogens or heavy metals.
Even at the heart of air-conditioning systems, compressors have become lighter and smaller in recent years, but passenger comfort has not been affected. The air conditioner compressor is connected to the drive engine through a belt and a clutch. Current and future compressors use electronic equipment to achieve a change in stroke control and work without a clutch. This alone can reduce the weight by 1.5 kg and allow the compressor to run according to specific needs. It also reduces the compressor's fuel consumption. Compared with conventional fixed-stroke compressors, the fuel consumption can be reduced by 0.2 to 0.3 liters/100 km.
Just now, I introduced various technologies that helped us to be more "green", but one thing that needs to be emphasized is that these technologies have their own merits. Different technologies have different advantages in environmental protection. Therefore, for the entire automotive industry, although we need to develop various or long-term or short-term solutions to make our planet more "green", we now have a lot of practical technology. Delphi is dedicated to helping automakers cater to consumer needs. However, as I said before, this is an extremely complex issue that requires a variety of solutions. There is no panacea on this issue. We believe that the best technologies and products are the technologies and products that are most suitable for market demand.
As an industry-leading enterprise and system supplier, Delphi has been committed to the development of various green technologies over the years and has been bringing many advanced technologies to China, including the technologies introduced above. We are conducting multi-level technical cooperation with Chinese OEMs and system manufacturers, and are actively conducting localization to bring more energy-saving and environmentally-friendly green products to the Chinese market. Delphi is pleased to see that China has taken the lead in the world in actively adopting alternative energy power plants. It is really gratifying to be able to see that Chinese consumers are increasingly concerned about issues such as energy, environment, and cost, and are actively looking for solutions.
I and my Delphi colleagues are very proud of our company's rich products, technology, and strong R&D capabilities. With Delphi's strong engineering capabilities in automotive R&D support, we are able to ensure that our customers quickly adopt popular technologies in the Chinese market. We fervently hope that we can further expand cooperation with Chinese automakers and help them to show their style on the world stage as soon as possible.
