Xinya m80 has run more than 60,000 kilometers, and its fuel consumption is higher than before.

Hello, my friend, running 60 thousand kilometers obviously increases fuel consumption, which is abnormal; The possible reasons are: ① insufficient cylinder pressure and increased wear. (It will reduce the useful work of fuel, that is, the force acting on the propulsion vehicle will be reduced) ② The spark plug is damaged, and the spark plug of a certain cylinder suddenly fails to ignite. Oil is sprayed, but it doesn't burn, which is equivalent to being discharged directly from the exhaust pipe. (3) The blockage rate of the fuel injector suddenly increases, and the fuel injection atomization is poor. (It will cause insufficient fuel, which will lead to insufficient combustion, and some fuel will be discharged with exhaust gas) ④ The air filter and intake pipe are blocked. (The uncoordinated mixing ratio of oil and gas leads to insufficient combustion) ⑤ The engine cooling system is not working properly. If the engine does not work at the optimal temperature, the fuel atomization will be affected, the cylinder resistance will increase, and the absolute useful work will be reduced. ) ⑥ Wear of chassis transmission system parts. (equivalent to starting a heavier car, because the friction increases) ⑦ The tire pressure is too low or the wear is seriously slipping (the friction with the road surface is too large, which will consume some power; If there is slippage, that is, the power does not play a practical role, it is a waste of oil.
