Abstract

FIELD: mechanical engineering; fuel systems of internal combustion engines. SUBSTANCE: proposed device has accumulating arrangement with spring-loaded working member installed to form air and fuel chambers. Working member of accumulating arrangement is made in the form of diaphragm with plunger and is provided with shaped regulators. Fuel chamber is connected with gas chamber through channel with check valve. Device has channel connecting gas chamber of accumulating arrangement with upper space of engine cylinder, channel being pointed of spark plug. It has also rod-valve to open and close the channel fitted on engine shaft and provided with cam or electronic control. Profile of stroke regulator is either wedge-shaped or made in the form of cam. EFFECT: reduced fuel consumption.
