Michigan State University in the US is developing a new hybrid engine that could deliver a five-fold increase in automotive fuel efficiency compared to the currently used internal combustion engine cars.

The University received a $2.5m grant from the Department of Energy for the project, which will be carried out over the next two years.

The project involves making a vehicle-size engine/generator, known as a wave disk generator, to convert liquid fuel sources or gases into electrical power using a turbo combustion ‘shock wave’ technique.

The new engine could replace the automotive internal combustion engine, radiator, water pump, fuel/air control, transmission and generator found in modern hybrid vehicles.

The engine is expected to reduce costs by 30% and CO2 emissions by 95%.
