Title: Two stroke engine with super charger - has direct fuel injection and full flow lubrication
Inventor: LUTZ JOACHIM
IPC: F02B33/40
Filed: 1975-04-04
Abstract: The engine has a turbo charger (1) which draws in clean atmospheric air and compresses it to pass to the cylinder intake transfer port (3). The port is uncovered by the piston (2) at the end of the power stroke and the incoming compressed air scavenges the cylinder and is then compressed by the piston. Fuel is injected directly into the combustion chamber and ignited by a high tension spark. The advantage claimed, is that a cleaner exhaust emission is obtained since the crankcase is no longer used as a precompression means and the lubricating oil does not have to be mixed with the fuel.
