Improving the engine power: It can increase the air density in the cylinder to let engine inject more fuel under the changeless displacement of engine,then to improve the power of engine. The power and torque will increase 20% ~ 30% after installing the turbocharger. Otherwise, it can reduce the engine cylinder diameter, also the volume and weight of the engine under the same power output requirement.
It is indispensable configuration to achieve over the EU two emission standard for diesel engine .
The earliest patent for the turbocharger was in 1905, Alfred Buchi Dr in company of Sulzer Brothers Research and Development applied for patent for the first turbocharger ----the axial power driven turbocharger, but based on the industrial level at that moment, Dr Buchi did not produce the first efficient turbocharger . It started in Winterthur turbocharger factory in Switzerland in 1911, and produced a prototype aircraft engine turbocharger in 1915.It main purpose was that driving the engine exhausting to overcome the negative impact of high altitude rarefied air to power. During the second world war, turbocharger produced by general electric (GE) made the airplane rise to ten thousand meters altitude.
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.
The engine stalled immediately is not allowed after engine worked long time with high speed. Some oil is offer lubrication and cool down for turbocharger rotor when engine is working. Working engine stalled suddenly , the oil pressure falls down to zero quickly. high temperature in the turbine transfers to middle, heat in the bearing and casing can’t go quickly meanwhile rotor is still turning with high speed as inertia. So engine stalled suddenly which is working will damage the bearing and rotor as too high temperature oil in the turbocharger. Specially to avoid to rush to refuel after stalled.
