Engine lower exhaust oil leaks.

1, the engine and exhaust connector are leaking oil and need to be replaced in the factory.

2. Oil leakage at the joint. It is very likely that your car has a serious phenomenon of burning oil. You have to check the engine dipstick to see if the oil is low. Less oil means burning oil.

technical characteristics

Principle of internal combustion engine

1, the engine valve drive mechanism adopts the structure of hydraulic bearing ball rocker arm. Compared with the hydraulic tappet valve drive mechanism widely used in general gasoline engines, this new valve drive mechanism has the advantage of relatively small friction torque, so it requires less driving force, which can effectively reduce the power consumption and fuel consumption of the engine.

2. In order to effectively reduce the weight of the whole vehicle, the 1.4 liter gasoline engine adopts aluminum alloy cylinder block, which achieves a very obvious lightweight effect.

3. Replacing the traditional metal intake pipe with the plastic intake pipe made of special materials and technology can not only achieve the effect of lightweight, but also effectively reduce the wall resistance of the intake pipe, improve the intake efficiency and increase the engine power.
