Turbocharger turbine exhaust gas temperature at the end of 600 ℃, often in high-speed high-temperature state, therefore, the need for effective mechanical cooling and lubrication. To be effectively guaranteed, vw passat 1.8 turbo it must be timely periodic maintenance and upkeep. In addition to normal maintenance, car drivers have to be careful, the turbocharger should always check there is no abnormal noise or unusual vibration, lube oil pipes and fittings have no leaks. Turbocharger rotor bearing high precision work environment requires maintenance and installation is very strict, so when the turbocharger should malfunction or damage to the designated repair station for repair.
Do not be impatient traffic stop
Because some of the features turbocharged engine determines a vehicle equipped with this engine has a certain skill in the parking and traffic, "impatient person driving this car is not conducive to vehicle maintenance."
Under normal circumstances, after the car engine starts, you can not slam the accelerator pedal, should be idle for three to five minutes. This is to enable the oil temperature, the flow properties better, so that sufficient lubrication of the turbocharger, and then to increase the engine speed, start driving. This point is particularly important in the winter, but at least need to idle more than five minutes, start to run after a few hundred meters should be uniform, passat 1.8 turbo and then slowly speed.
Equipped with a turbocharged engine of the vehicle in the parking also pay attention to. In the case of high-speed operation of the engine for a long time, do be careful not to turn off the parking immediately. This is mainly because when the engine is working, there is a part of the oil is supplied to the turbocharger rotor bearing lubrication and for cooling, running the engine suddenly stalled, the oil pressure drops rapidly to zero, oil lubrication will be interrupted. Thus, high temperature heat inside the turbocharger and the turbocharger turbine section, the bearing support housing and the heat will not quickly released, together with high-speed rotation is still under the effect of inertia of the turbocharger rotor, this will cause the turbine between the turbocharger shaft and sleeve "killed" and damage the bearings and shaft.
