Turbocharger (Mitsubishi Lancer 3)

The 125 hp/92 kW petrol engines (produced from September 1984 to August 1985) are equipped with a turbocharger. On one axis of the turbocharger sit two turbine wheels, placed in two housings isolated from each other. The turbine wheels are driven by useless exhaust gases. They accelerate the turbocharger axis to 120,000 rpm. And, since the rotors of the exhaust gases and fresh air sit on the same axis, fresh air is pumped into the cylinders at the same number of revolutions.

Thanks to the good filling factor, a power increase of up to 100% is achieved on existing engines. Among other things, the power increase depends on the boost pressure, which in a passenger car engine is from 0.4 to 0.8 bar (for comparison, the tire pressure is about 1.8 bar). When the boost pressure exceeds the value set at the factory, a valve opens, releasing the pressure.

Along with the power, the use of a turbocharger also increases the torque, which is very important in terms of ensuring the flexibility of engine control. However, the prerequisite is to ensure a high number of revolutions and thus a significant filling factor. As a rule, the engine must run at almost 2500 rpm to ensure a noticeable boost pressure.

The turbocharger is an element of extremely precise manufacture. Therefore, it is recommended to entrust its repair only to a good specialist. As a rule, if the turbocharger is defective, it is replaced as a set.
