| Brief description |
The difference between an conventional induction engine and the turbocharged engine is that the turbocharged engine has better filling during the intake stroke, which results in improved combustion, increased output, higher torque as well as lower fuel consumption. That is, performance that is comparable to a larger engine, but with maintained advantages of the smaller engine such as fuel economy, size, weight, etc.
Turbocharging is achieved through the use of a turbocharger, which means that the engine exhausts are used as a propellant. The exhausts are directed through an exhaust turbine and starts the turbine impeller rotating. The turbine impeller is attached to the same shaft as a compressor impeller and rotates at the same speed. The compressor wheel is positioned in the induction system and thus provides a pressure increase which results in improved filling in the combustion chamber.
The turbo compressor is dimensioned so that it begins to operate at relatively low engine speeds and there fore provides high torque in rpm ranges that are used during normal driving conditions.
