Abstract
The utility model discloses an installation seat for a fuel pump of an automobile engine. The fuel pump, an air inlet side camshaft phase sensor and a vacuum pump are integrally fixed on the installation seat, so that the entire structure of the engine is compact, and the entire space is optimized; an oil channel is further formed on the installation seat of the fuel pump seat, so that normal oil supply of the vacuum pump and the lubrication and cooling of an oil pump tappet are ensured; moreover, the seat is positioned by a positioning pin, so that the assembly error of the camshaft phase sensor is reduced. The installation seat is suitable for direct injection petrol engines of various turbocharging cylinders integrated with a camshaft, and is used for integrally fixing the fuel pump, the air inlet side camshaft phase sensor and the vacuum pump.
Description
Technical field
The utility model relates to a kind of vehicle motor member, specifically fuel pump, air inlet side integral type camshaft phase sensor, vacuum pump can be fixed a kind of motor car engine fuel pump fitting seat on it.
Background technique
The Incylinder direct injection that receives much attention in recent years (GDI:Gasoline Direct Injection) petrol engine, combine the advantage of diesel engine fuel oil inner cylinder direct injection, solve the deficiency of conventional P FI petrol engine preferably, become the developing direction and the ideal power of following car drive.The camshaft of in-cylinder direct fuel-injection engine has two kinds of structural types:
The one, the assembled camshaft structure, the fuel pump driving cam is arranged in the middle part of camshaft, and then fuel pump directly is arranged on the cylinder head cover.This class camshaft exists that production technology is comparatively complicated, price is comparatively expensive, cause defective such as relatively rotate between cam peach and body because of the cam peach is stressed than Da Yi during work;
The 2nd, the integral type camshaft structure adopts camshaft bearing lid and cylinder cap mode arranged apart more.There is following several respects defective in the integral type camshaft:
1) can only be arranged in the camshaft end because of the fuel pump driving cam, and then fuel pump just can not be arranged on the cylinder head cover, can only be arranged in the cylinder cap rear end, but the cylinder cap rear end there is not the fuel pump mounting structure, so this will cause designing peace component or dependency structure supports fuel pump;
2) because of fuel pump is arranged in the cylinder cap rear end, and vacuum pump can not be used the cylinder cap hydraulic pressure oil leab of holding out and lubricates this and will cause and must give the vacuum pump fuel feeding by the special oil duct of design, to guarantee the proper functioning of vacuum pump.
3) camshaft is an integral structure, make the camshaft signal dish can only be arranged in camshaft one side, and can not be arranged in the middle of the two cam peaches, thereby cause camshaft phase sensor can't be arranged on camshaft bearing lid or the cylinder head cover, so this will cause designing peace component or dependency structure is installed camshaft phase sensor, with the proper functioning of assurance camshaft phase sensor, and reduce sensor alignment error etc.
4) it is arranged apart with cylinder cap that motor adopts the camshaft bearing lid, causes the fuel pump driving cam can't be arranged in the camshaft middle part easily, as be directly installed on the cylinder head cover, causes the complete machine excessive height easily; If the reduction setting height(from bottom), just must be installed in wheel bearing lid and cylinder cap binding site, this just causes the petrol pump mounting hole need make up processing easily, the bad assurance of machining accuracy.

Said structure has guaranteed the proper functioning of high pressure oil pump.
As another kind of qualification the of the present utility model, described motor car engine fuel pump fitting seat is provided with in order to the oil spout of oil pump tappet and reduce the oilhole of its working surface temperature, described oilhole is drawn from cylinder cap hydraulic tappet oil leab, outlet is over against the fuel pump driving cam, and lubricant oil can directly be sprayed onto on the fuel pump driving cam from the outlet port.
This structure guarantees lubricated, the cooling and the proper functioning thereof of oil pump tappet.
The utility model also has a kind of qualification, and described motor car engine fuel pump fitting seat is provided with in order to the oil duct to the vacuum pump fuel feeding, and described oil duct is located between cylinder cap hydraulic tappet oil leab and the vacuum pump filler opening.
This structure realizes the fuel feeding to vacuum pump, guarantees the proper functioning of vacuum pump.
As a kind of optimization of the present utility model, be connected through bolt between described motor car engine fuel pump fitting seat and the cylinder cap, through seam and locating stud location is installed.
As further optimization of the present utility model, described installation seam is to be located at being used for and the joining projection of fuel pump fitting seat on the cylinder cap.
This structure can reduce the alignment error of camshaft phase sensor, more effectively guarantees the normal use of camshaft phase sensor.
Owing to adopted above-mentioned technological scheme, the utility model compared with prior art, obtained technological progress is: with fuel pump, intake-side camshaft phase detector, vacuum pump is integrated is fixed on the motor car engine fuel pump fitting seat provided by the utility model, make motor compact overall structure, the complete machine space layout that is optimized; On the fuel pump fitting seat, arrange oil duct further, guaranteed lubricated, the cooling of vacuum pump normal fuel injection and oil pump tappet; This employing locating stud is located in addition, has reduced the assembly error of camshaft phase sensor, reduces the motor manufacture cost.
