Abstract: |
This invention publicized belonged to the vehicle to pump/the valve - tube - mouth with the diesel oil injection system scope one kind of electric control in line combination to spray the diesel oil injection system. By the microcomputer unit, in-line type the charging pump, the electromagnetism control by-pass valve, the high-pressure oil pipe, the spray hole as well as the low pressure fuel oil system are composed. Installs after in-line type the charging pump has an electromagnetism control by-pass valve, the low pressure fuel oil system through the low pressure drill tubing and the electromagnetism control by-pass valve connected, bean through high-pressure oil pipe and electromagnetism control by-pass valve connected, in the microcomputer control unit has used the solenoid valve closure beginning feedback circuit or solenoid valve closure beginning signal, but is fast, the nimble adjustment controls the by-pass valve to the electromagnetism the controlled variable, has realized the fast numerical control which and fixed time adjusts to the oil mass; Is obtaining the stable injection pressure simultaneously to supply the oil function and fixed time to adjust the function decoupling, causes the oil pump structure and the control mechanism obtains the simplification, modifies slightly, has realized the low initial blow rate, high host spraying rate and the fast high pressure shuts off ideal blow rule. |
