Description

Auxiliary exhaust device for production test bed of internal combustion engine

Technical Field

The utility model relates to the field of internal combustion engines, in particular to an auxiliary exhaust device of an internal combustion engine production test bed.

Background

It is well known that the fuel line of a newly manufactured diesel engine is not filled with fuel, and the fuel line of the diesel engine must be filled with fuel to allow the diesel engine to operate normally. However, due to the presence of air in the fuel line, the air should be removed to clean the fuel line before the fuel line is filled with fuel. Before the auxiliary exhaust device is not used, the conventional method is to loosen the high-pressure oil pipe at the tail end to completely exhaust the air. To ensure that the air is removed cleanly, a large amount of fuel is discharged from the high pressure fuel line, which is very wasteful.

At present, most diesel engine manufacturing enterprises in China need to exhaust the whole diesel engine fuel pipeline in the production test process. The common method is to loosen the fuel outlet, such as a bleed screw on a diesel filter, an oil outlet of an oil pump, etc., and to ensure that gas is completely removed, a long time is often needed and a lot of fuel is wasted. Therefore, in order to solve the above problems, we propose an auxiliary exhaust device for an internal combustion engine production test bench.
