Wilksch Airmotive was a company based at Staverton Airport in Gloucester, England (United Kingdom) that specialises in designing, engineering, building and developing sensible and workable lightweight aero diesel engines for use in light aircraft burning Jet A1.

November 2019: A recent article about the WAM engine has been published in Unmanned Systems Technology Magazine - read it here...

The first flight of the 3-cylinder engine was on 31st December 1999, and there have been over 20 flying examples, together accruing thousands of flight hours, including one currently approaching the 1000 Hour mark.

A more recent development is the 4-cylinder engine, which produces 167HP in its initial specification.

The WAM compression ignition engines all offer class leading power to weight ratios, beating even Avgas based equivalents, and have a number of unique benefits designed specifically for the needs of the aircraft market.

Unfortunately despite the number of unique benefits designed specifically for the needs of the aircraft market, a lack of market adoption has lead to the cessation of this project, and this website is maintained for historical support only.

This video explains and shows the unique design aspects of our engines and gives you an insight into our factory and the facilities we have available.
