An electronic fuel injection control device for diesel engine

摘要

PURPOSE: An electronic fuel injection controller for a diesel engine is provided to improve durability by periodically changing a fuel injection valve and to improve combustion performance by controlling injection pressure and time. CONSTITUTION: An electronic fuel injection controller for a diesel engine is composed as follows. Injection pressure control valves(8) are installed in an air inlet(41) formed on the top of a fuel injection valve(4). The injection pressure control valves are opened and closed by corresponding with an air pressure control signal outputted from an engine control unit(5). The injection pressure control valves control air pressure supplied to the fuel injection valve. An injection starting control valve(3) is installed between fuel supply holes(32) formed in a fuel injection pump(2) and a nozzle body(40).
