FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: proposed fuel injection system for internal combustion engine contains atomizer with input, plunger with drive from cam limiting overplunger space connected with input of atomizer, high-pressure fuel accumulator, control valve installed between overplunger space and high-pressure fuel accumulator and making it possible to communicate, by electric control signal, overplunger space with high-pressure fuel accumulator and disconnect them from each other, and it is provided with electrically-operated control valve of atomizer designed for opening and closing of atomizer, device to build and regulate fuel pressure in high-pressure fuel accumulator, and fuel tank. Versions of fuel injection system are described in invention. ^ EFFECT: provision of new combination fuel injection system with mechanically driven plunger pump (injector unit) featuring possibilities of fuel injection with high-pressure fuel accumulator. ^ 21 cl, 11 dwg |
