Embodiment Construction

[0024] In order to further understand the present invention, preferred embodiments of the present invention are described below in conjunction with examples, but it should be understood that these descriptions are only to further illustrate the features and advantages of the present invention, rather than limit the claims of the present invention.

[0025] The first object of the present invention is to provide a kind of intake duct of engine, and the structural design of the intake duct of this engine can effectively solve the inhomogeneity of the amount of fresh air inhaled by each air outlet 2 of the intake duct, resulting in the working condition of each cylinder. A second object of the present invention is to provide an automobile comprising an air intake pipe for the above-mentioned engine.

[0026] The schemes in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the ...

Abstract

The invention discloses an air inlet pipe of an engine. An air inlet (3) is formed in one end of the air inlet pipe, a plurality of air outlets (2) are formed in the pipe wall of the air inlet pipe, and the area of the cross section of the air inlet pipe gradually decreases in the direction of being far away from the air inlet (3). When the air inlet pipe of the engine is used, part of fresh air is exhausted through the air outlet which is closer to the air inlet, due to the fact that the area of the cross section of the air inlet pipe decreases gradually, the flow velocity of the fresh air in the air inlet pipe is larger than the flow velocity of fresh air when the area of the cross section of an air inlet pipe is constant, more fresh air can flow into one end, far away from the air inlet, of the air inlet pipe, more fresh air can flow into the air outlet which is far away from the air inlet, and the amount of the fresh air flowing into the air outlets can be even. The invention further discloses the engine with the air inlet pipe.

Description

technical field [0001] The present invention relates to the technical field of engines, in particular to an intake pipe of an engine, and also relates to an engine with the above-mentioned intake pipe. Background technique [0002] The intake pipe of the engine is the main pipe of the engine intake system. The more fresh air the intake pipe sucks in, the more fully the fuel will be burned. In a multi-cylinder engine, the intake pipe has an intake port and a plurality of air outlets connected to the cylinders of the engine, wherein the intake port is at one end of the intake pipe, and multiple air outlets are distributed on the wall of the intake pipe , so that the distances between the multiple air outlets and the air inlets are all different. When fresh air enters the intake pipe from the air inlet, it will be exhausted from the air outlet along the direction of the air inlet pipe extension, so that the closer the air outlet is to the air inlet, the more fresh air it inhal...
