Problems solved by technology

However, the application of LPG has the following problems: 1. Because LPG gas occupies a certain volume in the intake charge, the engine inflation coefficient is reduced, resulting in loss of engine power; 2. The ignition temperature of LPG gas is high, making it difficult to start the engine cold; 3. The flame propagation speed of LPG is relatively lower than that of gasoline engines, and the combustion duration of the mixture gas is prolonged, which makes the afterburning of LPG gas engines serious, resulting in high exhaust temperature
Therefore, simply using LPG as an alternative fuel on a traditional motorcycle gasoline engine cannot guarantee the power output of the engine and the purpose of emission control

Description

[0001] Field: [0002] The invention belongs to the technical field of motor vehicle engine electronic control, in particular to an electronic control engine of a single-fuel LPG motorcycle. Background technique: [0003] At present, domestic motorcycle engines are mainly four-stroke gasoline engines. With the increasingly stringent national emission regulations, the use of alternative fuels such as LPG and engine electronic injection technology has become an effective technical means to solve motorcycle emissions. However, the application of LPG has the following problems: 1. Because LPG gas occupies a certain volume in the intake charge, the engine inflation coefficient is reduced, resulting in loss of engine power; 2. The ignition temperature of LPG gas is high, making it difficult to start the engine cold; 3. The flame propagation speed of LPG is relatively lower than that of gasoline engine, and the combustion duration of the mixture gas is prolonged, which makes the afte...
