Abstract
The utility model discloses a ventilation system of automobile engine, wherein, an exhaust piping (2) is provided with an exhaust branch pipe (4) and an exhaust main pipe (5), an exhaust pipe and a connecting flange (3) of a supercharger are arranged at the outlet of the exhaust piping (2), the exhaust branch (4) is directly connected with the exhaust pipe and the connecting flange (3) through each cylinder. The utility model with simple pipe structure and shortened pipeline, reduces the exhaust backpressure, reduces the energy loss, increases the amount of gas inlet impulse by making use of the turbocharger drove by the power of the waste gas to increase the amount of gas inlet, and improves the efficiency of the engine. The utility model is easy to be processed and installed.
Description
Technical field
The utility model relates to automobile chassis, and more particularly, the utility model relates to a kind of motor car engine air exchange system.
Background technique
Establish the outlet pipe system in the air exchange system of motor car engine, it is made up of exhaust branch pipe and exhaust manifold, and its effect is the waste gas that compiles each cylinder of motor, makes it to exhaust safely in the atmosphere to go.Its structure is the mouth of pipe of distribution air intake branch on the end face and connects with cylinder cap that another end face is the exhaust manifold mouth of pipe, connects with outlet pipe.The flow process of exhaust is that the waste gas of each cylinder at first enters exhaust branch pipe, compiles then to enter exhaust manifold, discharges by outlet pipe, silencing apparatus, tailpipe again.
At present, the exhaust piping in the general motor car engine air exchange system, pipeline is long, complex structure, and have crooked circular arc, exhaust back pressure increases, and causes the efficient of motor lower.Process and install also relatively more difficult simultaneously.
The model utility content
Problem to be solved in the utility model provides a kind of motor car engine air exchange system, its objective is the efficient that improves motor car engine.
To achieve these goals, technical solution adopted in the utility model is: this motor car engine air exchange system that is provided, establish exhaust branch pipe and exhaust manifold in the exhaust piping wherein, the outlet port of exhaust manifold is outlet pipe and pressurized machine adpting flange, and described exhaust branch pipe directly inserts outlet pipe and pressurized machine adpting flange from each cylinder location.
The utility model adopts technique scheme compared with prior art, makes exhaust pipe structure simple, and pipeline shortens, exhaust back pressure reduces, and reduces the exhaust energy loss, makes full use of exhaust energy and drives turbosupercharger, improve input stroke, air input of engine by air is increased, improved engine efficiency.Processing and installation are also more convenient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a sectional structure schematic representation of the present utility model;
Fig. 2 is the structural representation of looking up of the present utility model shown in Figure 1;
Fig. 3 is a plan structure schematic representation of the present utility model shown in Figure 1.
Number in the figure is: 1, outlet pipe and cylinder cap junction plane, 2, exhaust piping, 3, outlet pipe and pressurized machine adpting flange, 4, exhaust branch pipe, 5, exhaust manifold.
Embodiment
Shown in the structural representation of two different direction of the sectional structure schematic representation of the present utility model of Fig. 1 and Fig. 2, Fig. 3, the utility model is a kind of motor car engine air exchange system, establishes exhaust branch pipe 4 and exhaust manifold 5 in the exhaust piping 2 wherein.Effect of the present utility model is the waste gas that compiles each cylinder of motor, makes it to exhaust safely in the atmosphere to go.Form structure of the present utility model is outlet pipe and cylinder cap junction plane 1, the mouth of pipe of distribution air intake branch and connect on this junction plane with cylinder cap, and another end face is the exhaust manifold mouth of pipe, establishes outlet pipe and pressurized machine adpting flange 3, connects with turbosupercharger.The flow process of exhaust is that the waste gas of each cylinder at first enters exhaust branch pipe 4, compiles then to enter exhaust manifold 5, discharges by silencing apparatus, tailpipe again.
The utility model is in order to improve the efficient of motor car engine, taked to shorten as far as possible the technological scheme of the pipeline length of exhaust piping, and its embodiment is as follows:
The outlet port of described exhaust piping 2 is outlet pipe and pressurized machine adpting flange 3, and described exhaust branch pipe 4 directly inserts outlet pipe and pressurized machine adpting flange 3 from each cylinder location.In fact, the length of exhaust manifold 5 is close to zero in the utility model, and the shape of each exhaust branch pipe 4 is straight line as far as possible, reduces crooked as far as possible.
The technique scheme that the utility model is taked compared with prior art, make exhaust pipe structure simple, pipeline shortens, and exhaust back pressure reduces, reduce the exhaust energy loss, make full use of exhaust energy and drive turbosupercharger, improve input stroke, air input of engine by air is increased, improved engine efficiency, increase the torque of motor, especially improved the low speed torque of the motor of little discharge capacity, improved pick-up of engine.Because simple in structure, so processing and installation are also more convenient.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
