LinkedIn +

Engine test results have verified the performance of Torotrak Group’s unique new V-Charge variable-drive mechanical supercharger.

In comparison with the incumbent fixed-ratio positive-displacement supercharger on a 1.0-liter GTDI engine, V-Charge achieved improved brake specific fuel consumption, better transient performance and a maximum brake mean effective pressure of 31bar.

In sharing details of the development program, the company has shown a simulation using a GT-Power model and engine dynamometer testing, which was carried out at the University of Bath Powertrain and Vehicle Research Centre.
