experiment example
[0022]The experimental example is carried out on a Ricardo Hydra 140 single-cylinder experimental gasoline engine equipped with a 4VVAS system. The engine bore and stroke are both 86mm, and the compression ratio is 10.67. The experiment uses the equivalent air-fuel ratio, intake port injection, cooling The water temperature is controlled at 80°C, and the engine oil temperature is controlled at 55°C. The experimental results show that the controllable spontaneous combustion of gasoline engine can be realized under the condition of light load, and it saves a lot of fuel consumption compared with the traditional SI combustion. The most important thing is that after realizing the controllable self-ignition and heat release at small loads through the present invention, there is no need to switch the combustion mode at medium and small loads in practical application. For the commonly used urban road conditions, the engine will often work under small and medium load conditions. Afte...
