Product Parameter

Working principle of turbocharger

Exhaust gases from the engine driven pump impeller and pump wheel turns the turbine, a turbine after pressurized air intake system. Turbocharger installed on the exhaust side of the engine, so the working temperature of the supercharger is very high, and the supercharger rotor speed at work is very high, can achieve the similar RPM, high rotation speed and temperature makes common mechanical needle or ball bearing cannot work for the rotor, so the whole floating bearing widely used turbocharger, conducted by oil lubrication, and coolant The supercharger for cooling. Previously, the turbocharger are mostly used in diesel engines, now some gasoline engine also USES the turbocharger. Because of gasoline and diesel combustion mode is different, so the engine in the form of the turbocharger also differ.

The working principle of gasoline engine turbocharger

Gasoline engine is different from the diesel engine, it is not the air into the cylinder, but gas and air mixture, detonation pressure easilyCombustion. Installation turbocharger must, therefore, to avoid deflagration, here involves two related issues, one is the high temperature control, the other one is the ignition.Time control.

Mandatory after pressurization, gasoline engine compression and combustion temperature and pressure will increase, deflagration tend to increase.In addition, the gasoline engine exhaust temperature is higher than diesel engine, and unfavorable use increase valve heavy snow (into the door at the same time open time, gas) ways to strengthen the cooling exhaust, inadequate lower compression ratio and cause burning. Speed is higher than diesel and gasoline engine, air flow rate change is big, it is easy to cause the response of the turbocharger lag.

Product Application

The full range of turbochargers and related products are mainly used in commercial vehicles, construction machinery, mining equipment, marine power and generator sets, etc.
