Technical characteristics



The turbo-supercharging serves for improvement of filling of cylinders. In other words: the turbo-supercharging helps the engine to fill the combustion chamber on an absorption step with fresh gas (fuel-air mix). This filling is reached by the naturally aspirated engine due to absorption by the pistons moving in cylinders down, just the turbo engine does it better. For ensuring early the formed high torque on the wide range of turns the small turbocompressor with quick response was used.
