A silent diesel engine capable of realizing miniaturization and light weight

A light-weight technology for diesel engines, which is applied to mechanical equipment, intake mufflers, engine components, etc., can solve the problem of poor cooling effect of the air ducts at the cylinder head and cylinder holes and the air ducts at the bottom of the box, and can not guarantee the overall performance of the diesel engine. Heat dissipation effect, slow cooling air flow rate and other issues, to achieve the effect of low cost, simple setting, and reduced operating noise

Problems solved by technology

Traditional diesel engines are usually equipped with cylinder head and cylinder hole position air ducts and box bottom air ducts, which are used to cool the lubricating oil in the cylinder head, cylinder hole position and box bottom area respectively; however, due to the reduced size of the diesel engine, the internal space Narrow and narrow, the flow rate of the cooling air will slow down after being closed, the cooling effect of the air duct at the cylinder head and the cylinder hole and the air duct at the bottom of the box body will become poor, and the two air ducts can no longer guarantee the heat dissipation effect of the diesel engine

Embodiment Construction

[0024] like Figure 1-11 A silent diesel engine that can realize miniaturization and light weight is shown. Its main body is a diesel engine body 1. The diesel engine body 1 is provided with a cooling air duct system and a speed regulating device. The diesel engine body 1 is also provided with a lubrication system.

[0025] The cooling air duct system includes the cylinder head and cylinder hole air duct 2, the air duct 3 at the bottom of the box, the side air duct 4 of the high-pressure oil pump and the side air duct 5 of the air filter.

[0026] Cylinder head and cylinder hole position air duct 2: The cooling air enters from the starting cover 10, cools the cylinder head and the cylinder hole position, and finally enters the muffler 13 chamber to merge and discharge.

[0027] Air duct 3 at the bottom of the case: the cooling air enters from the starting cover 10, passes through the lower side of the crankcase 6, cools the lubricating oil in the crankcase 6, and finally enter...

Abstract

The invention discloses a silent diesel engine capable of realizing miniaturization and light weight. The diesel engine body is provided with a cooling air duct system and a speed regulating device, and a lubricating system is also arranged inside. The cooling air duct system adds a high-pressure oil pump side air duct and the side air duct of the air filter; the side air duct of the high-pressure oil pump and the side air duct of the air filter pass through the left area and the right area of ​​the crankcase respectively, and finally merge into the muffler chamber through the corresponding air inlet for discharge; the lubrication system includes four The lubricating oil channel and the second lubricating oil channel are provided with spray holes for splash lubrication. By adding two air ducts and setting up a new lubricating system, the invention can still ensure the heat dissipation effect and lubricating system of the whole diesel engine after the volume of the diesel engine is reduced and closed, so that the diesel engine can be realized by reducing the volume and adding a casing. Miniaturization, Lightweight and Silent.

Description

technical field [0001] The present invention relates to the technical field of engines, in particular to a silent diesel engine capable of realizing miniaturization and weight reduction. Background technique [0002] A diesel engine is an engine that burns diesel for energy release. The current diesel engine body is large in size, heavy in weight, and noisy during operation, which greatly limits the use environment of diesel engines. In order to reduce the size of the diesel engine and reduce the weight of the diesel engine, the usual method is to reduce the size of the diesel engine to reduce the volume of the diesel engine, and then use the all-inclusive casing (with the cooling air inlet and outlet) to seal the diesel engine. , to protect the diesel engine and reduce the noise when the diesel engine is running. Traditional diesel engines are usually provided with cylinder head and cylinder hole air ducts and air ducts at the bottom of the box, which are used to cool the...
