Square Piston Engine Reduces Emissions

The Square Piston Engine (SPEC), a two-stroke engine with a square piston, has an improved power-to-weight ratio compared to existing engines. The engine features the same three moving parts as a conventional two-stroke engine: crank, gudgeon, and piston. The delayed opening of the exhaust port on the power stroke provides a cleaner burn of the fuel, yielding more torque and lower emissions. The SPEC also has a closed-loop engine oiling system, which provides component durability and reduced hydrocarbon consumption. The engine is modular in design, providing significant manufacturing flexibility.

A number of prototypes have been constructed and have operated on a variety of fuels. One such prototype has run in excess of 500 hours. Further development work is required to enhance engine efficiency through software modeling of port placement.
