Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The synthetic pump in upright arrangement of monoblock pump type is by the totally-enclosed pump housing (1), low pressure oil transfer pump (2), electronically controlled unit pump assembly (3), drive cam shaft and bearing (5), CMPS Camshaft Position Sensor (6) is formed, electronically controlled unit pump assembly (3) comprises roller assembly (4) and solenoid valve (10), roller assembly (4) is installed the bottom of electronically controlled unit pump assembly (3), solenoid valve (10) is installed in the upper end of electronically controlled unit pump assembly (3), electronically controlled unit pump assembly (3) is packed in the totally-enclosed pump housing (1), a drive cam shaft (5) is inserted in bottom at the totally-enclosed pump housing (1), the two ends of drive cam shaft are equipped with full spring bearing (7), two of drive cam shaft, three cylinders and four, be separately installed with two and half spring bearings (8) between five cylinders, CMPS Camshaft Position Sensor (6) is housed on the totally-enclosed pump housing simultaneously, output links to each other by wire harness with ECU (Electrical Control Unit) (ECU) input of camshaft-signal sensor power supply with signal, and low pressure oil transfer pump (2) is installed on the totally-enclosed pump housing.
The utility model monoblock pump type synthesizes pump in upright arrangement, and low pressure oil transfer pump (2) can select to be installed in the anti-drive end face of the totally-enclosed pump housing, or employing and the same side that is contained in the totally-enclosed pump housing of conventional machinery pump in upright arrangement.
The utility model monoblock pump type synthesizes pump in upright arrangement, and low pressure oil transfer pump (2) can be selected rotator type or piston type for use.
The concrete working procedure of the utility model is: low-voltage fuel enters in the oil pocket at plunger (9) top through monoblock pump solenoid valve (10), plunger is up, build-up pressure in this oil pocket, if solenoid valve this moment (10) is in open mode, high pressure fuel communicates with the low-voltage fuel passage, and the fuel oil of not setting up high pressure flows back to low pressure area by solenoid valve; When solenoid valve (10) was closed, high pressure and area of low pressure isolated, and fuel pressure raises rapidly, and monoblock pump this moment (3) can begin outside fuel feeding.The size of the length may command fuel delivery of solenoid valve time, so control Engine Injection Mass what.And the moment that solenoid valve is opened once more (stopping power supply constantly) is controlled the fuel feeding stop time.So just realized the Flexible Control of motor injection process.
