The earliest turbocharger was used for racing car and formula car, so engine can get more power when the engine displacement is limited in the racing.
As we all know,The engine power relies on the work that the fuel is burned in the cylinder, entering the amount of fuel is limited by the amount of air in the cylinder,so the engine power will be also limited. If the performance of engine is in the best condition, to compress more air into the cylinder to increase the amount of fuel is the only way to increase the output power and improve the combustion power capability. So under the current technology, the turbocharger is the only mechanical device which can increase the engine output power under invariable work efficiency .
All people think about turbocharger is complex, but it’s not. Turbocharger is main composed of turbine and compressor. First turbine inlet connects with engine exhaust manifold, the outlet connects on exhaust pipe.Then compressor inlet connects with air filter pipe,outlet connects on inlet manifold, last turbine and impeller set in turbine housing and compressor, both connection on the shaft with rigid. Above is complete turbocharger , your engine just like your computer is “overclocking”.
The turbocharger which we usually refer to is actually a type of air compressor machine, it can increase the engine air inflow by compressing more air. Generally, the turbocharger use the inertial force of the engine exhaust to drive the turbine in turbine housing,then the turbine drives the impeller. The impeller compresses air which comes from the air filter and sends the air into the cylinder. When the speed of the engine gets faster, the speed of the exhaust outputting and turbine get faster at same time, the impeller compresses more air into the cylinder, the increasing of the air pressure and density can burn more fuel, the corresponding increasing of amount of fuel and adjusting the speed of the engine can increase the output power of the engine.
After the mandatory pressurization,the temperature and the pressure will increase when petrol is compressed and burned, detonation tend is more high .The exhausting temperature of the petrol engine is higher than diesel engine.It is unfavorable to use the method which increases the valve overlap Angle(the time of both the exhaust and intake valve opening at the same time) to strengthen lowering the temperature of the exhausting.To Lower down the compression ratio will cause the inadequacy burning.Speed of the petrol engine is higher than speed of diesel engine , air flow rate is big, it is easy to cause the response lag of the turbocharger.Focus on a series problems of petrol engine turbocharger, engineers targeted to do the improvement one by one in order to fit turbocharger on petrol engine.
Turbocharger’s main role is to improve the engine intake and to increase engine power and torque. An engine with a turbocharger, compared to one without it, increases its power by 40% or more. This means that an engine with a booster can have greater power. Our most common 1.8T turbo engines with a booster can reach the power of 2.4L while maintaining the fuel consumption level of the 1.8 engines. As a result, it improves the fuel economy and reduces tailpipe emissions.
