Abstract
The invention discloses an automobile engine, for which, at the V-like angle area of a cylinder, a crankcase waste-gas collecting pond is added, at the bottom of which, four vent holes are provided. The four vent holes are communicated with the crankcase comprising the cylinder and a frame, and guides waste gas into the collecting pond; four waste-gas channels are communicated with the cylinder head, so that the pressure in the crankcase and cylinders are even. The crankcase waste-gas collecting pond that is covered by a cover plate, the four vent holes at bottom of the pond, and the four waste-gas channels at the inner side of the V-like angle of the cylinder together form a crankcase ventilation, which reduces the flow speed of the crankcase waste gas when passing through the crankcase waste-gas collecting pond due to increase of the flowing area, so that the oil-gas separation efficiency of the mixture gas of crankcase waste gas is greatly improved.
Description
Technical field
The present invention relates to vehicular engine, more specifically to automobile V-shaped 6 Cylinder engine housing structures design.
Background technique
The air-breather of V-type engine cylinder body in the past is simple, and the crankcase waste gas passage is put on the inwall of cylinder block, directly leads to cylinder cap by the bottom of cylinder body.The circulation area of the access of this structure crankcase waste gas is limited, can not realize well that waste gas after burning is separated with machine oil steam in the crankcase waste gas, makes crankcase pressure too high, causes crankcase gas blowby and lubricating oil leakage phenomenon.
In order to improve the quality that waste gas after burning is separated with machine oil steam in the engine crankcase waste gas, the motor that has is in order to enlarge the circulation area of waste gas, adopt the area of the vent hole that increases the cylinder body inboard, make the cylinder wall that forms access bloat widely towards the inboard of cylinder in V-arrangement lateral body, it is big that width on the direction vertical with the inblock cylinder column direction becomes, thereby the cylinder block volume is increased, be unfavorable for the layout of motor on car load.
The motor that has then adopts the mode that increases external pipeline, forms a plurality of waste gas access, reaches the better separation of oil gas.But owing to be subjected to the restriction of the configuration of space that cylinder in V-arrangement body middle part V dihedral becomes and peripheral suction means, make motor become big, be unfavorable for that car load arranges.External pipeline has increased the complexity that motor assembles simultaneously, and exhaust gas leakage takes place simultaneously easily, influences the discharging of motor.
Summary of the invention
Technological scheme to be solved of the present invention provides a kind of V6 cylinder body that motor is arranged that is easy on car load.
Concrete technological scheme is as follows:
A kind of motor car engine comprises cylinder body, cylinder cap, waste gas access and intake manifold, it is characterized in that: at cylinder body V angular zone a crankcase waste gas collecting pit is set, the bottom of this collecting pit is provided with four vent holes, and the top is provided with cover plate.Vent hole is communicated with the crankcase that cylinder body and framework are formed, and waste gas is introduced collecting pit.Four vent holes are communicated with cylinder cap by four waste gas access, make that crankcase is interior and each cylinder pressure is even.
Crankcase waste gas collecting pit with cover plate for sealing, four vent holes with the collecting pit bottom, and four waste gas access of inboard, cylinder body V angle form a crankcase bleeder together on cylinder body, this device makes the flowing velocity of crankcase waste gas when the crankcase waste gas collecting pit, reduces because of the increase of circulation area.Intake manifold and cylinder cap assemble and are fixed on the crankcase waste gas collecting pit cover plate by support.
Adopt such scheme, increase a crankcase bleeder by middle part, V angle at V-type engine, at the active balance inner cylinder pressure, reduce the width of cylinder body and the quantity of peripheral pipeline when improving burning back waste gas and machine oil steam separating effect, make the engine structure compactness, be convenient to arrange at car load.And this device improves the circulating area of crankcase waste gas greatly, under the situation of not using other peripheral Oil-gas Separation pipelines, increases the waste gas circulation area, lowers flow velocity, makes Oil-gas Separation more abundant.
Owing to increase a plurality of access, enlarged the circulation area of crankcase waste gas, lower the waste gas flow velocity, make oil gas better separate.On this crankcase bleeder, increase a cover plate simultaneously and be used to support suction tude, make whole engine structure compactness, reduce the width of motor, be convenient to motor and arrange at car load.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
1,2 as seen in conjunction with the accompanying drawings, increased a crankcase waste gas collecting pit 3 at the V of cylinder body 1 angular zone 2, and four vent holes 4 are arranged at the bottom of this collecting pit.These four holes are communicated with the crankcase that cylinder body and framework are formed, and waste gas is introduced collecting pit, are communicated with cylinder cap 6 by four waste gas access 5 among Fig. 2, make that crankcase is interior and each cylinder pressure is even.
Usefulness crankcase waste gas collecting pit cover plate 7 pressurized crankcase gas sampling ponds 3 shown in Figure 3, with four vent holes 4 of collecting pit bottom, and four waste gas access 5 of inboard, cylinder body V angle form a crankcase bleeder together on cylinder body.This device makes the flowing velocity of crankcase waste gas when the crankcase waste gas collecting pit 3, reduces because of the increase of circulation area, makes the Oil-gas Separation efficient of crankcase waste gas mixed gas improve greatly.
Among Fig. 4, intake manifold 8 is fixed on the crankcase waste gas collecting pit cover plate 7 with cylinder cap 6 assemblings and by support, has effectively utilized the space in the V-type machine V angle, makes that the structure of motor is more compact, helps the layout of car load.
Invention has been described in conjunction with the accompanying drawings above; obviously specific implementation of the present invention is not subjected to the restriction of above-mentioned moulding; as long as the various improvement of having adopted layout of the present invention and technological scheme to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
