Low Pressure Electronic Fuel Injection System for Two-Stroke Engines

Abstract

<div class="htmlview paragraph">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.</div> <div class="htmlview paragraph">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.</div> <div class="htmlview paragraph">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.</div>
