Researchers tried to drive a gasoline engine based on the principle of a diesel engine to achieve high efficiency and low emissions. Delphi, a supplier of automotive parts parts, is currently developing an engine technology that can increase the fuel efficiency of gasoline vehicles by 50%, which has the potential to be comparable to that of hybrid vehicles and at a lower cost. The test base for this technology is similar to that of a highly efficient diesel engine, except that the fuel used is gasoline. The company has already demonstrated this technology and conducted simulation tests on the operation of this medium-sized automobile using this multi-cylinder engine. The results show that engines based on this technology may be far more efficient than diesel engines. The efficiency of a diesel engine using fuel to drive a car is 40% to 45%, and the efficiency of a gasoline engine is about 30%. However, diesel engines are more polluted and require expensive exhaust gas treatment technologies to meet emission standards. For decades, researchers have been trying to drive gasoline engines based on the driving principle of diesel engines to achieve high efficiency and low emissions. Such engines may be less expensive than hybrid technologies because they do not require large amounts of batteries and electric motors. Traditional gasoline engines are spark ignition fuel and air mixtures. Diesel engines are rapidly ignited by the direct fuel injection combustor by heating with compressed air. Some researchers have tried to use gasoline for compression ignition, but there are still challenges in controlling such engines, especially under load conditions where the car is idling, accelerating, and cycling at different speeds. Delphi's method is gasoline direct injection compression ignition. The aim is to overcome these problems by using advanced direct fuel injection and intake and exhaust control, many of which have been applied to current advanced engines. For example, the researchers found that if direct injection of gasoline occurs at three precise timings of deflagration, excessive combustion can be avoided, and fuel can be burned faster than conventional gasoline engines at the same time for maximum fuel efficiency. Researchers also use other strategies to improve the operation of the engine under extreme loads. For example, when the engine has just started or is running at low speed, the temperature of the combustion chamber is too low to achieve ignition combustion. Under these conditions, the researchers introduced exhaust gas into the combustion chamber to promote combustion.
