【Abstract】 Through the theoretical analysis and test, some satisfactory additives with high octane value to light oil were studied, and alternative fuels based on light oil were developed. The performance test and the parameter analysis of process in cylinder proved that the light oil based fuel had a high antiknock property. The spark ignition engine using light oil based fuel has a good combustion stability. The power and economy performance can reach or surpass the levels of that using gasoline. Since the light oil based fuel has high octane value, the engine can work with high compression ratio, which improves the power and economy performance greatly. The light oil based fuel can become a good alternative fuel for spark ignition engine.更多还原
