Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0024] Such as Figure 1 to Figure 3 As shown, the water jacket exhaust manifold includes exhaust channel 1, water jacket channel 2, engine cooling water main channel 3, exhaust channel 1, water jacket channel 2 and engine cooling water main channel 3 are integrally cast The overall structure is integrated into one part, reducing the number of engine parts, the structure is simple and compact, and the overall quality is reduced.

[0025] The exhaust passage 1 is arranged in the cavity of the water jacket passage 2, the engine cooling water main pipe 3 passage is arranged outside the exhaust passage 1, the exhaust passage and the water jacket passage and the engine cooling water main pipe passage are arranged side by side inside and outside, and the structure is compact. The water passing throu...

Abstract

The invention discloses a water-jacket type exhaust manifold and an engine provided with the same. The water-jacket type exhaust manifold comprises an exhaust channel, a water jacket channel and an engine cooling water master pipe channel, wherein the exhaust channel is arranged in a cavity of the water jacket channel; the exhaust channel, the water jacket channel and the engine cooling water master pipe channel are of an integral structure. The engine comprises the water-jacket type exhaust manifold. Due to adoption of the integrated engine cooling water master pipe channel, the number of parts and components of the engine is effectively reduced, the structure is simple, the overall size specification is reduced, the overall quality is reduced, the light-weight design requirement is met, and the reliability and the stability of a power system are effectively improved; in addition, by means of the integrated engine cooling water master pipe channel, the purpose of recovering waste heat of exhaust gas can be realized, the temperature of internal cycling water is rapidly promoted, the common problem that the water temperature rise speed is low after the engine is started is greatly improved, and the engine can enter a stable working condition as soon as possible.

Description

technical field [0001] The invention relates to the technical field of engine exhaust, in particular to an integrated water-jacketed exhaust manifold and an engine with the same. Background technique [0002] The water jacket exhaust manifold is widely used in high-power marine engines or other special power equipment. The exhaust manifold of the engine is cooled by the water jacket to prolong the service life of the exhaust manifold. [0003] However, the existing engines with water-jacketed exhaust manifolds have many complex structures, many parts, cumbersome installation, low production efficiency, large space occupation, not compact enough, and inconvenient layout, resulting in heavy weight of the power system as a whole, which cannot Meet the lightweight design requirements; and the water temperature rises slowly after the engine is started, and it takes a long time for the engine to enter a stable working condition. Contents of the invention [0004] Aiming at the ...
