DIESEL FUEL FEED ACCUMULATING SYSTEM

摘要

FIELD: engines and pumps.SUBSTANCE: proposed system comprises fuel feed channels (2), accumulating chambers (7 and 8), pistons (9) and springs (10). Accumulating chambers (7 and 8) with pistons (9) and springs (10) are arranged in separate housing (3) for engine two cylinders. Fuel is forced via fuel lines (2) from high-pressure fuel pump into first accumulating chamber (7) and, via control channels (6), to slide valve (12). The latter opens to let fuel from second accumulating chamber (8) flow via fuel feed channels (4) to appropriate fuel injectors. Besides, operation of accumulating chambers allows ordered operation of engine cylinders.EFFECT: higher efficiency of fuel feed, simplified system and reduction of costs.2 dwg
