Brief description, V6

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 turbocharger is designed to start working at low engine speeds and therefore delivers a high torque in engine speed ranges that are attained in normal running condition.

By introducing adjustable guide rails on the turbocharger, it now has a faster reaction time at low engine speeds.

The guide rails are adjusted for low exhaust flow so that the inlet area on the exhaust side is reduced. As the inlet area is reduced, the speed of the exhaust flow will increase. In this way, the turbocharger can deliver a high boost pressure even at low engine speeds. The guide rails are adjusted so that the inlet area becomes larger as the torque request increases or the required boost pressure becomes lower.
