Abstract
The invention relates to an arrangement type of a high-pressure common-rail fuel injection system of a V-shaped eight-cylinder diesel engine. The arrangement type includes that a high-pressure pump (1) is mounted inside a V-shaped included angle of the diesel engine and is close to a transmission end, right-row common-rail pipes (3) are arranged on right gas inlet pipes of the engine, left-row common-rail pipes (8) are arranged on left gas inlet pipes of the engine, common-rail diesel injectors (5) are arranged on cylinder covers (2), the right-row common-rail pipes (3) are communicated with the corresponding common-rail diesel injector (5) via high-pressure pipelines (4), the left-row common-rail pipes (8) are communicated with the corresponding common-rail diesel injector (5) via high-pressure pipelines (4), the right-row common-rail pipes (3) are communicated with the left-row common-rail pipes (8) via a lower high-pressure pipeline (6), and the high-pressure pump (1) is communicated with the left-row common-rail pipes (8) via an upper high-pressure pipeline (7). The arrangement type has the advantages that the high-pressure capacity of the integral system can be reduced, and accordingly the arrangement type is favorable for controlling starting and the rail pressure of the engine.
Description
Technical field
The invention belongs to diesel engine high-pressure co-rail system field, be specifically related to a kind of V-type 8 cylinder diesel high pressure common rail fuel injection system layout patterns.
Background technique
The layout pattern of high pressure common rail fuel injection system is divided into according to the complete machine pattern of motor: type in upright arrangement and V-type.Specific to the layout pattern of high pressure co-rail system component, can be divided into: single high-pressure service pump, single common rail pipe, common-rail injector are in one line according to the arrangement mode of cylinder; Single high-pressure service pump, two common rail pipe, common-rail injector are arranged on respectively in each cylinder cap mounting hole according to the complete machine layout pattern of V-type machine.But the two common rail pipe high pressure co-rail system layout complexity of existing single high-pressure service pump: the high pressure fuel that high-pressure service pump produces is assigned to high pressure fuel in left and right two rows' common rail pipe by fuel dispenser, the high pressure volume of whole system is larger, is unfavorable for engine start and rail pressure control.
Summary of the invention
The present invention solves V-type machine pressure duct complicated layout and the larger problem of high pressure volume existed in prior art, and a kind of V-type 8 cylinder diesel high pressure common rail fuel injection system layout patterns are provided.
Technological scheme of the present invention: a kind of V-type 8 cylinder diesel high pressure common rail fuel injection system layout patterns, it comprises high-pressure service pump 1, right row's common rail pipe 3, pressure duct 4, common-rail injector 5, pressure duct 6, pressure duct 7 and left bank common rail pipe 8, it is characterized in that high-pressure service pump 1 is arranged on the inner position near driving end of diesel engine v-angle, right row's common rail pipe 3 is arranged on the suction tude of engine right side, left bank common rail pipe 8 is arranged on the suction tude in motor left side, common-rail injector 5 is arranged on cylinder head 2 in the common-rail injector mounting hole, right row's common rail pipe 3 is communicated with by pressure duct 4 with common-rail injector 5, left bank common rail pipe 8 is communicated with by pressure duct 4 with common-rail injector 5, right row's common rail pipe 3 is communicated with by pressure duct 6 with left bank common rail pipe 8, high-pressure service pump 1 is communicated with by pressure duct 7 with left bank common rail pipe 8.
Remove on described right row's common rail pipe 3 outside the high voltage interface that connects each cylinder common-rail injector, a high voltage interface is set at least, for arranging pressure duct 6 again.
Remove on described left bank common rail pipe 8 outside the high voltage interface that connects each cylinder common-rail injector, two high voltage interfaces are set at least, for arranging pressure duct 6 and pressure duct 7 again.
Beneficial effect of the present invention: in the present invention left bank common rail pipe 8 integrated the function of the two common rail pipe high pressure co-rail system layout pattern intermediate fuel oil distributors of single high-pressure service pump in the past, lowered the high pressure volume of whole system, more be conducive to engine start and rail pressure control; V-type engine high-pressure fuel oil system setting type cost was low, lightweight more in the past in the present invention, reasonable structural arrangement.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
