Having a wastegate lets the turbocharger act like a big turbo at low RPM, and a standard size turbo at higher RPM. This is one of the single most problematic VGT turbos you will ever encounter. It has a low boost threshold and is very efficient at higher engine speeds. Temperamental Turbo. One disadvantage of simple turbos is that they tend to have a fairly narrow effective RPM range which can adversely affect drivability and make it difficult to predict and control torque response. A variable geometry turbo for a diesel engine controls engine exhaust flow through the turbine wheel using a row of vanes. Are functor categories with triangulated codomains themselves triangulated? The main function of the turbocharger is to control the air-to-fuel ratio in your diesel engine. Lower drive pressure, increase spool-up, power and performance. And a variable geometry turbo makes the engine so much more drivable - earlier boost, smoother, progressive : see duratirq Ford/Jaguar as one out of many examples. These vanes are located around the turbine and are controlled by an actuator. Wastegate technology helps to prevent turbocharger over-speeding, as well as engine over-boost.
