Wuhan City once carried out "oil to gas" on two lines, that is, using modified technology to transform the original fuel vehicle into a liquefied gas vehicle. But less than half a year, had to "gas to oil" of the original modified car, the reason: First, the performance of the car after the transformation is not satisfactory, some of the modified attachments are easy to damage, the failure rate increased, the power dropped by 6% ~ 10%, of which 530 modified 18 dedicated line operators had 235 failures in one month. Second, environmental performance is not optimistic. The carbon content of the modified vehicle's exhaust is even higher than that of the fuel vehicle. The qualified rate of exhaust gas emission test is only 50%, and it is impossible to achieve the desired economic and environmental protection goals. There is not enough awareness of the special requirements for the maintenance and use of gas vehicles. After all, gas cars are different from fuel cars, so they are also different from fuel cars in maintenance and use.
If this is not fully understood, it will result in poor maintenance and operation of gas vehicles and poor emission control. For example, gas vehicles should use dedicated gas vehicle lubricants. When the car uses natural gas, the combustion chamber temperature is higher than when using fuel. Generally, the exhaust temperature of the diesel engine is about 300°C, while the exhaust manifold temperature of natural gas vehicles is as high as 482-694°C. At the same time, the oil temperature is also higher than when the fuel oil is used. Continuous high temperature operation will cause premature oxidation of the common oil and gradually lose the lubrication function, which will aggravate machine wear, resulting in poor engine operation and emission deterioration. For liquefied gas vehicles, the engine oil must also be a low-ash lubricant, because high ash lubricants will form hard deposits under the high temperature of the combustion chamber, which will increase the wear of pistons and intake valves and even cause premature combustion. The service life of the engine.
