Two-stroke engines produce a lot of pollution because the fuel-air mixture in them gets contaminated with the engine’s lubricating oils. Simultaneously the combustion chamber draws in the contaminated mixture as exhaust gases are expelled through an exhaust port. Some of the fuel and oil gets mixed with the exhaust.
Envirofit’s fix replaces the engine’s carburetor, which mixes the air and fuel before they enter the combustion chamber, with a direct in-cylinder fuel-injection system. This allows fuel to enter the combustion chamber when the exhaust port is closed. Eliminating nearly all the unburned fuel significantly reduces the ensuing smoke and hydrocarbons. The conversion kit includes an air compressor, wiring harness, custom brackets, and a new cylinder head.
