Cause and analysis of excessive fuel consumption in engine
Let's sum up some of the main fuel consumption in our daily driving. We hope it will help you save your oil. Man will artificially increase the power loss of the engine. At the same time, excessive braking will increase the number of starts, and the fuel consumption at the beginning
(4) the timing of ignition is inaccurate, such as ignition too late. (5) the cylinder pressure is too low. Practice has proved that the cylinder pressure is lower than the prescribed value, and the fuel consumption is increased by 20% to 25%. (6) incorrect phase of valve timing. (7) the exhaust gas recirculation valve is sluggish and often open. (8) winter use of lubricating oil or oil filling too much.
(1) the air filter is blocked and the air inlet is impeded, which makes the mixture gas too strong or the exhaust pipe is blocked. (2) the idle speed adjustment is not correct. Errors such as CO adjustment. (3) engine coolant temperature is too high or too low. The coolant temperature is too high, the cooling liquid is easy to boil, the power is down, the fuel consumption is increased, the coolant temperature is too low, the mixed atomization is not good, the engine power is reduced, and the oil consumption is increased
