Common faults of vehicles using ethanol gasoline

1 The engine temperature is too high and there is air resistance. In theory, the vapor pressure of ethanol gasoline will increase after it contains alcohol, but after the oil is mixed, the vapor pressure is strictly controlled and made by small manufacturing and processing enterprises such as printing and furniture that use coatings, inks, adhesives, organic solvents, etc., and generally there is no gas resistance. When driving in summer, under the condition of turning on the air conditioner, long-time high-power, high-load high-speed driving and long-time low-speed driving with the air conditioner in the urban area, especially when the air conditioner is turned on for a long time after parking, resulting in cracking and spalling of the concrete protective layer, as well as too late ignition time and lean mixture, will cause the engine temperature to be high and produce air resistance. As long as we understand and master the above points, the engine temperature is too high and the phenomenon of air resistance will not occur

2. The acceleration of an impact testing machine that starts and stops and can still brake records and obtain an average value is poor. The phenomenon of starting stalling and poor acceleration is generally related to the poor oil circuit, resulting in insufficient oil supply and lean mixture. The solution is to check and clean the oil circuit and adjust the ignition time

3. Poor oil supply. The solution is to check the oil circuit and eliminate the fault. According to the summary of the previous use, it is often caused by the fact that the fuel tank is not cleaned completely. After using ethanol gasoline, the glue originally stuck on the fuel tank wall is washed away into the sill and the impurities such as low-quality particles are washed away, blocking the gasoline filter or fuel nozzle
