Engine test bench

Abstract

The invention provides an engine test bench. The engine test bench comprises an engine support which is used for supporting an engine, an oil supply device which is connected with an engine oil tank which is used for supplying fuel oil to the engine, an engine oil supply device which is connected with an engine oil pump which is used for providing engine oil for the engine, a water circulation device which comprises a water supply tank and a cooling water tank, and a control cabinet. The water supply tank and the cooling water tank are connected through a pipe. The water supply tank is connected with an engine water pump through a water supply pipe. The cooling water tank is used for cooling the engine oil tank. The engine oil tank is connected with the engine oil pump. The control cabinet comprises an instrument panel, a water temperature controller and a rotation speed controller. The instrument panel is connected with a built-in sensor of the engine to display a signal detected by the built-in sensor. The water temperature controller is used for controlling the water supply temperature of the water circulation device. The engine test bench has the advantages of improved test efficiency and reduced test cost.

Description

technical field [0001] The invention relates to a vehicle test system, in particular to a vehicle engine test stand. Background technique [0002] During engine maintenance, it is often necessary to test the engine. Most of the traditional engine tests use the hot car test, that is, to test the various parameters of the engine under the condition of the engine burning and doing work, so as to judge whether the parts and assembly of the engine are qualified. The main disadvantage of this test method is that the test efficiency is low, and environmental pollution such as noise and exhaust gas are likely to be generated during the test. [0003] In addition, most of the current engine test systems are aimed at engine manufacturers, and are used to test the performance of the engine before the engine leaves the factory. Its characteristics are: 1) The test process is complicated and the test method is complicated; 2) The test cost is high and the site is occupied Large area; 3...

AI Technical Summary

Problems solved by technology

The main disadvantage of this test method is that the test efficiency is low, and it is easy to generate noise, exhaust gas and other environmental pollution during the test.

[0003] In addition, most of the current engine test systems are aimed at engine manufacturers, and are used to test the performance of the engine before the engine leaves the factory. Its characteristics are: 1) The test process is complicated and the test method is complicated; 2) The test cost is high and the site is occupied Large area; 3) The system itself is complex and the maintenance cost is high

Therefore, the existing engine testing system is only applicable to engine development and production units, not to grass-roots maintenance units
