FIELD: engines and pumps.
SUBSTANCE: pulse diesel fuel feed system includes fuel tank, low pressure fuel pump connected by means of suction line to fuel tank and by means of low pressure line to HP pump sections on each of which electromagnetic bypass valve is installed, electromagnetic atomisers arranged in diesel and connected by means of high pressure line to electromagnetic bypass valves, and by means of drain line to fuel tank. Electronic control unit is electrically connected to rotation frequency sensor and to position sensor of crankshaft, to each of electromagnetic bypass valves and to each electromagnetic atomiser. In addition, pulse diesel fuel feed system is provided with high pressure fuel accumulators arranged in each high pressure fuel line between electromagnetic bypass valves and electromagnetic atomisers equipped with discharge valves, high pressure fuel sensors electrically connected to electronic control unit.
EFFECT: invention allows reducing technical requirements for accuracy of electromagnetic valves included in composition of such atomisers and simplifying their manufacturing procedure, thus reducing prime cost of the whole atomiser.
