Embodiment Construction

[0014] exist figure 1 , 2 , 3, 4, an engine intake manifold, the intake manifold is arranged and connected between the two cylinder heads of the V-type engine, the lower body 2 of the intake manifold is designed as a pressure-stabilizing chamber, and the pressure-stabilizing chamber has an inlet Air port, the upper body 1 of the two intake manifolds intersects, and is connected with the lower body 2 of the intake manifold through the connecting hose 3 and clamp 4 .

[0015] Such as figure 1 As shown, the upper body structure of the intake manifold is designed as a flange surface connected to the cylinder head. Three branch pipes come out from the flange surface. The air passages of the branch pipes are parallel and of the same length. The structure of the entire intake manifold is simple and easy to cast.

[0016] Such as figure 2 As shown, the structure of the lower body of the intake manifold is designed as a pressure-stabilizing chamber, and there are 6 connection outle...

Abstract

Disclosed is an intake manifold for an engine. The intake manifold is arranged and connected between two cylinder heads of a V-shaped engine; the lower part of the intake manifold is designed as a pressure-regulating cavity which is provided with an intake; the upper parts of two intake manifolds intersect and connect with the lower part of the intake manifold via connecting hoses and clamps. In order to ensure the strength of a manifold branch on the upper part of the intake manifold, connecting ribs are arranged among manifold branches. Since the upper part of the intake manifold only adopts a cross structure, the intake manifold is arranged between two cylinder heads of the V-shaped engine, and the upper parts of the two intake manifolds intersect and connect with the lower part of the intake manifold via the connecting hoses and the clamps, so that arrangement is compact and space is fully utilized; lengths between the intake manifolds and gas passages of cylinders are designed as identical, structure is simple, casting process is convenient, and gas intake of each cylinder of the engine is uniform.

Description

technical field [0001] The invention relates to an engine intake manifold, in particular to a 6-cylinder engine intake manifold Background technique [0002] The layout design of the engine intake manifold is an important part of the engine design. The traditional 6-cylinder engine is in-line, the engine body is long, and the layout in the front compartment is not compact. Most of the 6-cylinder engines now use a V-shaped structure, and the engine is relatively short in-line. At present, the lengths of the intake manifolds of most cylinders are not designed uniformly, and the intake air of each cylinder of the engine is not uniform. The structure is also more complicated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an engine intake manifold with uniform air intake and simple and compact structure in order to make up for the shortcomings of the existing engine intake manifold. [0004] The present invention...
