subject: Brief Introduction Of Turbocharger [print this page] Most of us like watching automobile race, because it is exciting and breathtaking. You may wonder why the race car runs that fast. The secret for the fast speed lies in the turbocharger. Then what a turbocharger is? Here is the answer: diesel turbocharger is a kind of air compressor which is used to increase air inflow by compressing air. Turbocharger makes good use of inertia momentum of the waste gas to drive the turbine in the turbine room. Then the turbocharger puts the impeller which shares the same axle in motion. At last the impeller sends the air brought by the air filter to the cylinder. The faster the engine runs the larger output power the engine will have. The above information is far from enough, you'd better know more about it.
Function
The biggest advantage of turbocharger is that it can improve the power and torsion to the largest extent on condition that the engine capacity is normal. Generally speaking, the power of an engine can be improved by20-30 percent.
Operating principle
Before talking about the working principle, we'd better know some component of turbocharger. Turbocharger is mainly made of pump impeller, turbine as well as some control elements. The pump impeller and turbine is connected by an axle which is known as rotor. The exhaust gas discharged by the engine drives the pump impeller then the pump impeller drives the turbine. At last the turbine runs to supercharge the air intake system. The supercharger is installed near the engine. So the operating temperature is rather high. When working, the rotor of the supercharger runs very fast at the speed of more than 100 thousand r.p.m.
Dos and don'ts
Given the high speed and high temperature working environment, the turbocharger should be paid attention to. Following are two basic principles.
1. Keep the turbocharger clean
When dismantling the garrett turbocharger, you should make sure that every pipe should be block off by some clean cloth so as to preventing sundries from entering into it. Sundries in the turbocharger will do harm to the rotor.
2. Check certain parts before driving
It is an indispensable step to check the connection between pipes to make sure that they are soundly connected before and after your drive. Any looseness and shed tend to cause failure of the turbocharger.
I'm confident that you must know what a turbocharger is since I have introduced the function, operating principle as well as dos and don'ts. Knowing this is far from enough. You should apply it to your daily life. Take care of the turbocharger and your car! That is ultimate goal.
