Abstract
The utility model discloses an exhaust manifold for a horizontal engine, comprising an exhaust manifold body. An air inlet end flange is arranged at one end of the manifold body, and an air outlet end flange is arranged at the other end of the manifold body; a collection pipe for collecting exhaust gas in the manifold body is as transverse and horizontal as the air inlet end flange; the collecting pipe is communicated with the air inlet end flange by a vertical manifold branch pipe; the connection parts between the manifold body and the air inlet end flange as well as the air outlet flange are transited in an arc way; and the manifold body is provided with an heat shield installing boss. The size from the end surface of the air inlet end flange of the exhaust manifold to the low end of the air outlet end flange is smaller, so that when the exhaust manifold is arranged on the horizontal engine, the width of an engine assembly is reduced, the structure is compact, the arrangement is convenient, and the exhaust manifold facilitates to improve the performances of a whole vehicle.
Description
Technical field
The utility model relates to a kind of gas exhaust manifold, especially relates to a kind of horizontal engine and uses gas exhaust manifold.
Background technique
Little in recent years car sales volume significantly promotes, and the relevant automotive engineering of little car is developed fast.For satisfying the demand of micro vehicle market, need exploitation to be suitable for the motor that little car uses.Make its more compact structure, be convenient to arrange.At present, vertical engine can not satisfy little car general arrangement needs, therefore need retrofit, and being about to original vertical engine Transform Type design is horizontal engine; This Transform Type design also need design the air inlet system and exhaust system of motor except satisfying engine crankcase ventilation and lubricating oil return again, and wherein the gas exhaust manifold of motor is the critical component of vent systems.Existing gas exhaust manifold is installed on the horizontal engine, and the engine assembly overall width is big, is not easy to arrange.
The model utility content
The purpose of the utility model provides a kind of horizontal engine and uses gas exhaust manifold, and the existing gas exhaust manifold of solution is used in and makes the engine assembly width big on the horizontal engine, the problem that structure is not compact.
The utility model solves the technological scheme that its technical problem adopted: a kind of horizontal engine is used gas exhaust manifold, comprises manifold body, and described manifold body one end is provided with the inlet end flange, and the other end is provided with the outlet side flange; The influx pipe that compiles exhaust in the described manifold body is the same with the inlet end flange to be all anyhow, and influx pipe and inlet end flange are connected through vertical manifold arm, and described manifold body and inlet end flange, outlet side flange connections are arc transition.
Preferably, described manifold body is provided with the thermal shield installation base.
Preferably, described manifold body is provided with lambda sensor the screw boss is installed.
Preferably, described manifold body, thermal shield installation base, inlet end flange, outlet side flange and lambda sensor installation screw boss pour into an integrated entity through vermicular cast iron.
The beneficial effect of the utility model: owing to compile be all anyhow the same of influx pipe of exhaust in the manifold body with the inlet end flange; Between directly connect through short manifold arm, and manifold body and inlet end flange, outlet side flange connections are arc transition.Shortened the size of inlet end end face of flange flange low side to the outlet side of gas exhaust manifold greatly, be installed in the engine assembly width is reduced, compact structure is convenient to arrange, is very helpful to improving vehicle performance.
Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.
Description of drawings
Fig. 1 uses the gas exhaust manifold organigram for the utility model horizontal engine.
Among the figure: 1. manifold body, 10. influx pipe, 11. manifold arms, 2. the thermal shield installation base, 3. the inlet end flange, 4. the outlet side flange, 5. lambda sensor is installed the screw boss.
Embodiment
As shown in Figure 1, use gas exhaust manifold for a kind of three cylinder horizontal engines, comprise manifold body 1, manifold body 1 upper end is provided with inlet end flange 3, and the manifold body lower end is provided with outlet side flange 4; The influx pipe 10 that compiles exhaust in the manifold body 1 is the same with the inlet end flange to be all anyhow; Influx pipe 10 is connected through three vertically short manifold arms 11 with inlet end flange 3; Three manifold arms of its manifold body are arc transition in the joint from left to right and between the inlet end flange, and transition arc radius is respectively 31mm, 35mm, 39mm; The influx pipe of manifold body and outlet side flange connections also are arc transition, and transition arc radius is 130mm, and this arc transition can reduce the size of joint, can effectively reduce the exhaust interference effect of each cylinder again.Described manifold body 1 is provided with three and is used for fixing the thermal shield installation base 2 that thermal shield is installed.Be provided with lambda sensor near outlet side flange place on the described manifold body 1 screw boss 5 is installed, wherein the center line of lambda sensor installation screw boss becomes 30 ° of angles with the outlet side end face of flange.Distance is 115mm to the inlet end end face of flange of this gas exhaust manifold to flange bottom, outlet side.The manifold body of this gas exhaust manifold, thermal shield installation base, inlet end flange, outlet side flange and lambda sensor are installed the screw boss and are poured into an integrated entity through vermicular cast iron; For avoiding causing extra casting defect owing to pipe wall thickness is inhomogeneous, the rising head of cast is arranged on inlet end flange place.
The inlet end end face of flange of this gas exhaust manifold is less to the size of outlet side flange low side, is installed in the engine assembly width is reduced, and compact structure is convenient to arrange, is very helpful to improving vehicle performance.
