Low Pressure Electronic Fuel Injection System for Two-Stroke Engines 780767

AFTER MAKING A QUICK GENERAL SURVEY of the different injection systems which have been testing for some years, the author describes a new direct low pressure fuel electronic injection system specially adapted to the two stroke engine.
Very short time of about a millisecond can be obtained at high flow variation by controlling electromagnetically the balistic movement of the injector needle. The monitoring electronic control can be carried out by an opto-electronic memory or a static one (M. O. S.) by microprocessing.
The performances of such system are specially interesting with regards to the specific fuel consumption decreases about 30 to 40 per cent compared with an engine fed through a carburettor. The unburnt H.C. emission level, which until now condemned the two-stroke engine, are greatly decreased.
