Turbocharging single-cylinder engines to increase power, improve efficiency, and reduce emissions

Amos Winter and Michael Buchman

Many diesel-powered devices (delivery vehicles, tractors, generators, etc.) in emerging markets use single-cylinder engines.  They have to meet ever increasing emissions standards, where required exhaust treatments result in loss of mechanical power.  We are developing a turbocharging technology that could increase the power of single-cylinder engines by as much as 60% and increase efficiency.  This technology could have significant impact in counties such as India, providing more power while contributing to improved air quality.
