高油耗的分析检测与降低油耗方案（Analysis and detection of high fuel consumption and fuel consumption reduction plan） Transfer - high fuel consumption analysis and test and reduce fuel consumption program Although the Chevrolet sail, but above the general Sail high fuel consumption detection and analysis scheme to reduce fuel consumption The car for a long time, a lot of car fuel consumption will be increased, with the brand, the same year, the same road, also run for many kilometers of car fuel consumption will be very different, our friends of O, some 7-L/100km, some 13-14L/100km, the high fuel consumption is certainly a fault, the fault must be solved the method that how to detect and reduce the fuel consumption? And listen to elder brother slowly way: Whether it is car or car, first of all should know how to burn the fuel injection quantity of engine fuel is mainly determined by the amount of intake air flow meter (OO, by car is the intake manifold absolute pressure sensor) measurement of air intake, then the control system (computer) to calculate the appropriate amount of fuel injection, fuel injector drive. Engine work. Injection amount is appropriate, signal by oxygen sensor (according to the oxygen content of exhaust oxygen content and air ratio voltage), feedback to the computer to deal with, if appropriate (in the theoretical air-fuel ratio near 14.7:1), to maintain the same amount of fuel injection, if not appropriate (and the theoretical air-fuel ratio difference the computer will update, large), given the new fuel injection quantity, until the appropriate date. This process, in order to other conditions into account, as well as the influence of the operation parameters of the engine, the intake air temperature sensor, temperature sensor, solar term door position sensor, engine speed sensor, knock sensor such as auxiliary (boundary) conditions, and sent to a computer, the injection quantity of comprehensive analysis and calculation are suitable, which makes the power of
