Routine maintenance of vehicles to use ethanol gasoline five-point pay attention to - maintenance
, gasoline - Automotive repair and maintenanceEthanol Gasoline engine ignition assembly suitable for various types of vehicles, whether carburetor or EFI fuel supply means vehicles. It can effectively improve the performance and quality of oil, reduce carbon monoxide, hydrocarbons and other major pollutants.

Because some of the characteristics of ethanol fuel itself, the use of ethanol in gasoline should pay attention to the following matters:
For first-time use inside the vehicle before washing
Ethanol Gasoline in ethanol solution has a strong cleaning properties. The first use of ethanol gasoline vehicles, especially the use of a box to the 2 tank of fuel after the cleaning effect of ethanol, would fuel tank, oil line of precipitation, accumulation of various impurities such as rust, dirt, gum particles dissolved softening down, mixed with oil, resulting in poor oil line.
Therefore, in general mileage at 30,000 km above the dirty fuel supply system and to identify the vehicles before the use of ethanol fuel should be cleaned. Cleaning operations should be qualified with the second category above Vehicle Maintenance Factory strictly according to specifications, focusing on the fuel tank, fuel filter, oil pump, carburetor, fuel injectors, Fuel and oil line filter cleaning one by one.
The cleaning process should pay attention to the elimination of fuel tanks, oil system of impurities, discharge of water accumulated at the bottom of the tank. Gasoline with ethanol can not meet some of the rubber, plastic parts replacement, cleaning test carried out after the inspection, and vehicle adaptation.
Second, to prevent excessive moisture inside the engine
Vehicle ethanol gasoline mixtures as a certain amount of denatured fuel ethanol, ethanol is a hydrophilic liquid, easily miscible with water, unlike gasoline, petrol can and water separation, water deposited on the bottom of the tank. Therefore, the first use of motor vehicles, ethanol in gasoline, the tank should conduct an inspection to prevent the bottom tank of petrol and ethanol precipitation of water solubility may exist, so that excessive moisture in oil, affecting the normal operation of the engine.
3, summer use should pay attention to
Higher summer temperatures, the volatility of fuel increases, such as tank accessories?? Exhaust valve plug, so that part of the fuel from liquid into gas, the gas can not be discharged by the exhaust valve is easy to cause air resistance of asphalt generate probability increases. Refueling summer not to overfill the tank, to leave enough space for oil expansion and gasification.
4, ethanol and gasoline impact on the rubber
Results show that the vast majority of rubber can adapt to ethanol fuel, only a few not meet, but the slow corrosion. Some of the early production of mechanical rubber diaphragm fuel pump in poor adaptability, the use of ethanol gasoline swelling occurs after the individual the cracks. As the rubber component can not be distinguished in appearance to material composition, can be fixed Auto Repair Plant parts will be purchased in advance to be a vehicle ethanol gasoline immersion test, and then loading use. Long-term use should be considered in the Rubber and fuel supply system components is organic corrosion resistance to alcohol.
5, according to the compression ratio to use ethanol gasoline
Vehicle ethanol gasoline and regular gasoline as to its label is marked by octane, labeling is labeling the former petrol filling letters E. In general, the compression ratio of 7.5 to 8.0 should use E90 ethanol fuel vehicle numbers; compression ratio in the 8.0 to 8.5 in the vehicle number should be used E93 ethanol petrol; compression ratio at 8.5 to 9.0 should use E95 ethanol fuel vehicle numbers; compression ratio of more than 9.0 should be used in E97 ethanol gasoline car number.
