Diesel engine hood and manufacturing technique thereof

Abstract

The present invention discloses a diesel engine hood. The diesel engine hood comprises an engine hood body, the top part of the engine hood body is provided with a top chute, and cooling metal sheetsformed integrally with the engine hood body are arranged inside the top chute and are spaced equally. Support projections used for installing a dust shield are disposed inside left and right part of the top chute. Venting holes are formed in the middle part of the dust shield. A bottom chute is disposed under the engine hood body and is internally provided with an acoustic panel, and noise reducing bosses are formed on the surface of the acoustic panel. Heat of the engine hood body is absorbed by the cooling metal sheets and dissipates from the venting holes formed in the dust shield, facilitating cooling of an engine body. The acoustic panel is convenient to assemble and disassemble. Noise produced by the engine body is transferred to and thus absorbed by the noise reducing bosses on thesurface of the acoustic panel.

Description

technical field [0001] The invention belongs to the technical field of a diesel engine cover, and in particular relates to a diesel engine cover and a manufacturing process thereof. Background technique [0002] The engine cylinder head is mounted on top of the cylinder block, sealing the cylinder from above and forming the combustion chamber. [0003] Due to the heat and noise generated in the combustion chamber of the engine block, the engine block is required to have a good heat dissipation effect in order not to overheat the engine in working condition, but the heat dissipation ability of the existing engine block to the engine block is relatively weak, and its The noise of the body will produce poor user experience. Therefore, we propose a diesel engine cover and its manufacturing process to solve the problems mentioned in the above background technology. Contents of the invention [0004] The object of the present invention is to provide a diesel engine cover body a...
