The utility model is achieved through the following technical solutions: a kind of diesel engine is provided, comprises oil pump, water pump, high-pressure common rail electric injection system, also be provided with automatically controlled rotating open-close type valve gear, bent axle mlultiple-groove sheave.Described oil pump is located at crankshaft of diesel engine mlultiple-groove sheave below, water pump is located at bent axle mlultiple-groove sheave upper left side, high-pressure common rail fuel oil high-pressure service pump is located at bent axle mlultiple-groove sheave upper right, the bent axle mlultiple-groove sheave is connected transmission by belt with each pump, inlet and exhaust valve adopts described automatically controlled rotating open-close type valve gear, and oil-fired system is used existing high-pressure common rail electric injection system.
Described automatically controlled rotating open-close type valve gear is made up of valve seat housing, valve, valve guide bushing, regulator, valve seat, plane bearing, spring, spring flap, locking plate.Valve gear and controllable motor socket transmit signal by CKP and give micro computer ECU, constitute a whole set of automatically controlled rotating open-close type valve gear by micro computer ECU control controllable motor.
Described valve and valve seat respectively are provided with breach, and the breach of the notch alignment valve seat of valve is air inlet or exhaust condition, otherwise are closed condition.
Outstanding feature of the present utility model is:
1, owing to removed driving gear, camshaft mechanism, adopt automatically controlled rotating open-close type valve and use existing high-pressure common rail electric jet technology, reduced conventional diesel engine quick-wear part 50%, diesel engine is selective under low load condition to stop a part of cylinder work, makes diesel engine reduce oil consumption 15% to 18%.
2, owing to oil pump, water pump, high-pressure common rail fuel oil high-pressure service pump is located at by the body, has made things convenient for observation machine run situation, and inspection and maintenance is more convenient.
3, adopt described automatically controlled rotating open-close type valve gear, engine valve does not clash into Quack when opening and closing, and not easy to wear, the controllable motor power consumption is little, and torsion is big, and is particularly accurate to the best valve timing diagram of motor, improves horsepower, reduces oil consumption.Combine with the high-pressure common rail electric injection system of contemporary motor, can make engine thermal efficiency higher, toxic emission is lower.
4, part adopts modularization and generalization, and superior performance is simple in structure, compact.
