Fuel pressure controller for engine, adjusts level pressure in fuel supply path depending on temperature of engine during stoppage |
摘要 |
The fuel feed pump (2) is controlled based on feedback signal, to get target fuel pressure near fuel injection valve (4). During stoppage of engine, the fuel pressure in fuel supply path (3) is adjusted depending on temperature of engine during stoppage. The fuel pressure control apparatus has a fuel tank (1) connected with fuel supply path equipped with feed pump (2). The path equipped with non-return valve (5) supplies fuel to the common storage which is fitted with fuel pressure sensor (7). Multiple fuel injection valves are attached with common storage. A control unit (8) equipped with air flowmeter (10), crank angle sensor (11) and temperature sensor (12) is located at the exterior.
