Description

Auxiliary system module of diesel engine

The present invention relates to a simplified device by modularizing the auxiliary system of a diesel engine, and more particularly, a system without connecting a lubricating oil supply device, a supercharger, and a cooling water supply device required for driving a diesel engine. The present invention relates to a device modularized in bulk. In addition, it includes the actual implementation of the cooling water circulation circuit in connection with the cooling system of the previously applied diesel engine (Application No. 99-030583).

In general, in diesel engines used for ships or industrial use, the lubricating oil supply device is composed of a circuit including a supply pump, a cooler, a temperature setting valve, and the like. The supercharger is composed of a circuit including a supercharger, an air cooler, and the like. The cooling water supply device is divided into a low temperature circuit and a high temperature circuit and has a respective supply pump.

Conventionally, by using the method of connecting the above circuits in a pipe as shown in FIG. 1, the structure of the entire system is very complicated, requires a lot of installation space, and low productivity.

In addition, since an arrangement structure in which each component and the pipe interfere with each other is inevitable, there is an inconvenience of disassembling all other interfered parts for maintenance.

An object of the present invention to solve the above problems is to simply modularize the entire system required for engine operation, including the cooling water circulation circuit mentioned in the cooling system of the previously applied diesel engine (Application No. 99-030583) without piping. In order to commercialize products in a manner, the engine is downsized and the structure of the module frame is simplified to facilitate casting and processing, thereby improving productivity. Also, when disassembling and assembling each functional part, other parts are not interfered with. It is to provide an easy to maintain auxiliary system module (Auxiliary System Module) device by allowing the assembly and disassembly at once.

In order to achieve the above object, the present invention arranges a coolant pump, a lubricating oil pump, a lubricating oil filter, a lubricating oil cooler, an air cooler, a temperature setting valve, and the like so that they do not interfere with each other during disassembly and assembly. Each circulation circuit is simply completed by forming and connecting a flow path.

In addition, the casing of the coolant pump, the lubricating oil pump, and the temperature setting valve has a cylindrical structure and an inlet is installed at the circumference of the cylinder for smooth connection and easy installation of each component with the internal flow path of the module frame. The internal structure of the module frame is created by directly connecting the internal passage of the module frame and creating a structure in which the casing itself can serve as a partition wall that separates the internal passage of the module frame. Simplify even more.

It is also achieved by providing a device in which the outlet and inlet of the lubricant cooler, air cooler, etc. are directly connected to the internal passage of the module frame.
