DESC:FIELD
The present disclosure generally relates to the field of engines. More specifically, the present disclosure relates to intake manifolds for engines.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Conventionally, the intake manifold is designed with a separate intake pipe having serrations at one end for enabling hose connection. The conventional design has all the components of the intake manifold distributed separately, thus forming many child parts during the assembly of the intake manifold. The conventional design therefore makes the whole assembly process time consuming and laborious. Further, the conventional design of the intake manifold does not provide uniform distribution and mixing of the exhaust gas over all the runners of the intake manifold. Also, the conventional design requires a separate intake pipe to facilitate mixing of the exhaust gas. However, employing separate intake pipe requires additional mounting boss/gaskets for mounting the intake pipe, thereby increasing complexity of the arrangement.
There is, therefore, felt a need for an intake manifold for an engine that alleviates the aforementioned drawbacks.

The present disclosure envisages an intake manifold for an engine. The intake manifold for an engine (hereinafter referred to as “intake manifold 100”) is now described using Figure 1 through Figure 5.
The intake manifold 100 comprises an upper shell 230, a lower shell 215, an exhaust gas entry port 105, and a plenum 110. In an embodiment, the material of intake manifold 100 is composite plastic. In another embodiment, the material of intake manifold 100 is cast iron. In yet embodiment, the material of intake manifold 100 is aluminum. In an embodiment, the intake manifold 100 is configured to be integrated with a long duct pipe column (not shown in figures). The duct pipe facilitates uniform mixing of exhaust gas before inward bound to the plenum 110. This facilitates uniform distribution of the exhaust gas over the runners 108 of the manifold. In an embodiment, the intake manifold includes four runners 108.
The lower shell 215 is configured to be fastened with the upper shell 230 to form the intake manifold 100. In another embodiment, the upper shell 230 is fastened with the lower shell 215 via plastic insert 210. The rubber gaskets 220 and compression limiters 225 are provided between each cylinder of the engine and a runner of the plurality of runners 108 to facilitate secure connection therebetween. The gaskets 220 and limiters 225 facilitate leak proof connection between the cylinders and the runners 108. In an embodiment, the intake manifold 100 includes a plastic insert 210 having shape of a conduit that facilitates passage of fresh air therethrough.
The exhaust gas entry port 105 is configured to receive a fraction of recirculated exhaust gas. The plenum 110 is configured on the lower shell 215. The intake manifold 100 is configured to receive fresh air through a fresh air intake port 101. The intake manifold 100 facilitates uniform mixing of the recirculated exhaust gas with fresh air or charge upstream of the plenum 110 and further facilitates uniform distribution of the air-fuel mixture therethrough.
In an embodiment, the lower shell 215 includes a plurality of runners 108 configured thereon. Each of the runners 108 is configured to be in fluid communication with a respective cylinder of a multi-cylinder engine.
The integration of the long intake pipe with the intake manifold 100 provides a lightweight and cost-effective solution which further eliminates the need for a separate intake pipe and additional mounting boss/gaskets. In an embodiment, the weight of the intake manifold 100 is further reduced by using a common wall and selecting plastic as the material. Also, the manifold 100 takes less time for assembling and facilitates easy removal.
