DRAINLESS FUEL INJECTION SYSTEM FOR DIESEL INTERNAL COMBUSTION ENGINES

摘要

The system is used in the manufacturing of engines and offers determined values of the design parameters of some elements, ensuring normal operation of the engine under all operating conditions. The ratio between the exhaust stroke volume Vv of the compression valve (1) of the fuel injection pump A and the overall volume of the compression circuit is 0.028 - 0.037, while the ratio between the gap Cv of the exhaust girdle of the compression valve (1) in its seat (2) and its diameter is 0.0003 - 0.00083. The ratio between the volume corresponding to the full stroke of the needle (7) when elevating and the volume Vc of the cavity (8) is 0.0078 - 0.012, while the ratio between the increased gap Cn of the needle (7) in the body of the sprayer (6) and its diameter dn is 0.0005 - 0.0012.
