The Lindsey Engine® is a patented, clean sheet design for an engine that could potentially deliver very
significant improvements in efficiency and fuel economy. Our initial modelling indicates an improvement in
efficiency at part load of up to 37% over traditional engines. The engine could be configured to run on petrol,
or a range of alternative fuels including hydrogen and various biofuels. Small, lightweight, quiet, with fewer
parts than a traditional engine and using well-understood materials and technology, the engine has very
The engine has diverse potential applications, from electricity generation through marine power and potentially
the automotive sector. Initial priority markets include 2-stroke replacement, Combined Heat and Power and
Unmanned Aerial Vehicles.
The Lindsey Engine® is a development from the Blade Compressor™, and shares the basic mechanical design.
Two units are connected to create a traditional four stroke cycle, one performing induction/compression the
other combustion/exhaust. The engine therefore offers the potential to optimise compression/combustion ratios and
temperatures which, together with improved airflow, significantly improve energy efficiency over traditional engines.
