In recent years there has been substantial investigation into heavy-fuel (diesel or JP-8) engine technologies with the goal of producing small engines (in the 5 horsepower range) for a number of useful applications within both military and commercial areas ranging from unmanned vehicles to power… More

A new approach is needed to bypass the problems which have thus far limited the development of small heavy-fuel engines. Typically these compromised engine designs are hard to start, they do not burn the fuel cleanly or completely, their ignition timing is inconsistent, their high peak pressures… More

The military has a great need for very small, heavy-fuel (diesel or JP-8) engines for a wide variety of applications (e.g. small, unmanned air and ground vehicles, and power generation). Likewise the commercial small engine market (lawn tools, chainsaws, and model aircraft) can benefit from engines… More
