Description
Technical Field
The utility model belongs to the internal-combustion engine field relates to an auxiliary exhaust apparatus of internal-combustion engine production test bench.
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, it is necessary to provide an auxiliary exhaust device for an internal combustion engine production test stand to reduce exhaust time and fuel consumption.
