Abstract
The utility model discloses a diesel gasoline dual-purpose high pressure oil pump assembly of a diesel engine, which comprises a pump body (1) and a plunger piston (2) arranged in the inner chamber of the pump body. The pump body is provided with a terminal pad (4) with a screw (3). The high pressure oil pump assembly is characterized in that the outer end of the plunger piston (2) is fixedly connected with a mandril the outer end of which is connected with a pulley (6); the outside of the pump body (1) is provided with a pedestal seat (7) which is opposite to the terminal pad (4). The high pressure oil pump assembly is arranged on one side of an engine body of a camshaft. The camshaft drives the mandril and the plunger piston to do reciprocating movement. As the mandril is added, the distance between the pump body and the engine body of the camshaft is widen; therefore, the high temperature of the engine body of the camshaft can not be conducted to the pump body and the temperature of the pump body greatly reduces, thus being capable of meeting the petrolic use condition and realizing the purpose that both of the diesel and the gasoline can be used.
Description
Affiliated technical field
The utility model belongs to a kind of engine components, a kind of specifically high-pressure fuel injection pump assembly.
Background technique
Current, international market petroleum resources height is in short supply, and supply falls short of demand to cause diesel oil, and the diesel engine user refuels the difficulty even the oiling of limiting the quantity of.Comparatively speaking, gasoline is much better than diesel oil, and it is many easily to add gasoline.And conventional diesel engine has many disadvantages such as fuel utilization ratio is low, fuel consumption is high, noise is big, the discharging flue dust is many.Therefore, original diesel engine is become the multi-purpose apparatus that also can use gasoline, become vast diesel engine user and thought long and hard the important topic of trying to explore.Existing diesel engine, the high pressure oil pump of employing and camshaft body close-coupled, camshaft and plunger directly contact.Under nominal situation, the temperature of piston is 350 degree, and the cylinder sleeve temperature is 250 degree, and body is 100 degree, and the oil pump temperature that closely links to each other also is 100 degree with it.This temperature is also comparatively suitable for diesel oil, and just too high for gasoline, when gasoline runs into 100 degree high temperature, forms gas at once, causes and can't work.This is the main cause that present diesel engine can't use gasoline.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of diesel engine diesel oil and gasoline dual-purpose high voltage oil pump assy is provided, and it not only can use diesel oil, can also use gasoline, and is simple in structure, is convenient to make or repacking.
For reaching above-mentioned purpose, the utility model is taked following technological scheme: the utility model includes: the plunger in the pump housing and the inner chamber thereof, the pump housing is provided with the land of band screw, it is characterized in that: the push rod that has been fixedly connected in the plunger outer end, and the push rod outer end is connected with pulley; Be provided with a base disk relative in the pump housing outside with land.
The utility model is taked technique scheme, has following beneficial effect: when the utility model uses, it is installed on camshaft body one side, is touched mutually with camshaft by the pulley of push rod outer end, base disk docks with the camshaft body and is fastening by connecting rod.During work, the camshaft high speed rotating drives push rod and plunger moves reciprocatingly pump housing work.The utility model is owing to set up the push rod transmission, connecting rod is fixed, make between the pump housing and the camshaft body not close-coupled, but widened distance, like this, the high temperature of camshaft body just can not conduct to the pump housing, and pump body temperature reduces greatly, can satisfy the service condition of gasoline, realize the purpose that diesel oil, gasoline can both use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model structure diagram.
Mark among the figure: the 1-pump housing, 2-plunger, 3-screw, 4-land, 5-push rod, 6-pulley, 7-base disk, 8-center hole, 9-attachment hole, 10-connecting rod
Embodiment
By shown in Figure 1, the utility model includes: the plunger 2 in the pump housing 1 and the inner chamber thereof, the pump housing 1 are provided with the land 4 of band screw 3, the push rod 5 that has been fixedly connected in plunger 2 outer ends, and push rod 5 outer ends are connected with pulley 6; Be provided with a base disk 7 relative with land 4 in the pump housing 1 outside.Base disk 7 of the present utility model is provided with center hole 8 and the attachment hole 9 relative with screw 3, is fitted with connecting rod 10 in screw 3 and attachment hole 9, and push rod 5 outer ends insert in the center hole 8.
Claims (2)
