Embodiment Construction

[0031] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description are only These are some embodiments of the present invention. Those skilled in the art can also obtain other drawings based on these drawings without creative work.

[0032] In order to make the drawing concise, each drawing only schematically shows the parts related to the present invention, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components having the same structure or function is schematically shown, or only one of them is marked. Herein, "a" not only means "only one", but also means "more than one".

[0033] It should also be further u...

Abstract

The invention provides an engine, comprising: a cylinder head; an intake manifold, the intake manifold is arranged on the cylinder head and communicated with the cylinder head; an exhaust manifold, the exhaust manifold is arranged on the cylinder head And communicate with the cylinder head; EGR valve, the EGR valve communicates with the exhaust manifold, the EGR valve is located above the cylinder head; EGR cooler, the EGR cooler communicates with the EGR valve, the EGR cooler Set above the cylinder head, the EGR cooler cools the gas discharged by the EGR valve, and the EGR cooler communicates with the intake manifold; part of the gas discharged by the engine from the exhaust manifold passes through the EGR valve in turn and EGR cooler, and then return to the engine from the intake manifold. The invention effectively saves the installation space by arranging the EGR valve and the EGR cooler above the cylinder head. The gas first passes through the EGR valve and then through the EGR cooler, which improves the service life of the EGR cooler and reduces the carbon in the EGR valve. deposition.

Description

technical field [0001] The invention relates to an engine, especially an engine suitable for automobiles with an EGR assembly. Background technique [0002] In the prior art, the EGR valve and the EGR cooler are usually arranged on the side of the engine block, and the engine installation requires a relatively large floor space. The high-temperature gas discharged from the engine first passes through the EGR cooler and then reaches the EGR valve. The EGR cooler is also easily damaged by high temperature and the carbon deposition rate in the EGR valve is relatively high. Therefore, it is necessary to provide an engine to overcome the above-mentioned defects. Contents of the invention [0003] It is an object of the present invention to provide an engine with an EGR assembly. [0004] According to one aspect of the present invention, an engine is provided, comprising: [0005] cylinder head; [0006] an intake manifold, the intake manifold is arranged on the cylinder hea...
