Université of Sherbrooke Builds a Less Polluting Two-StRoke Hydrogen Engine

A team of researchers from Université de Sherbrooke’s Faculty of Engineering, in collaboration with engineers from the Centre de technologies avancées BRP-Université de Sherbrooke (CTA), have built a small two-stroke engine that barely pollutes and whose efficiency is optimal.

The prototype works on hydrogen injection. This new type of engine is strong enough to power a small 250 cc recreational vehicle or even a motorcycle. Jean-Sébastien Plante, Professor at the Université de Sherbrooke’s Department of Engineering, says that commercialization at an affordable price is possible within 5 to 10 years .

The Sherbrooke team’s innovative success lies in the fact that they resolved two problems associated with two-stroke engines: high hydrocarbon emissions and loss of energy efficiency. The Sherbrooke researchers designed a new cylindrical head which increases the compression ratio so it can be incorporated directly into an hydrogen injection system while maximizing its efficiency.

Even if the motor developed by the research team is destined for the small vehicles market, it could eventually have a major impact in the worldwide transportation market.
