Problems solved by technology

[0003] However, due to the complexity of the gas pipeline of the diesel engine, the correspondingly designed starting system can only be known whether the starting system can work normally after being installed on the diesel engine and powered on. This test method directly installed on the diesel engine may damage the diesel engine. It increases the cost of test verification, and it is also difficult to quickly troubleshoot the problem of the starting system during the operation of the diesel engine

Embodiment Construction

[0053] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the embodiments of the present invention.

[0054] In order to thoroughly understand the embodiments of the present invention, a detailed structure will be set forth in the following description. It is evident that practice of the embodiments of the invention is not limited to specific details familiar to those skilled in the art.

[0055] At present, all diesel engines have multiple cylinders, for example, 8, 12, 16, 20 cylinders and so on. When the diesel engine needs to do work, air can be injected into the cylinder of the diesel engine and diesel is injected. The diesel is ...

Abstract

The invention provides a test platform and a control method of a diesel engine starting system, the diesel engine starting system comprises an air distributor and a starting valve, the air distributor is used for accessing compressed air, and the test platform comprises a starting simulation device, a starting air pipeline and a phase sequence monitoring system. The starting simulation device is used for driving the air distributor to rotate; the starting air pipeline is used for connecting the air distributor and the starting valve; the phase sequence monitoring system is used for monitoring the opening and closing state and sequence of the starting valve. The starting simulation device drives the air distributor to rotate, so that the air distributor conveys accessed compressed air to the starting valve through the starting air pipeline, and the phase sequence monitoring system monitors the opening and closing states and sequence of the starting valve. According to the test platform, the design function of the diesel engine starting system can be tested, faults can be checked in time, the test verification efficiency is improved, meanwhile, direct installation to the diesel engine for verification is avoided, and the verification cost is reduced.

Description

technical field [0001] The present invention generally relates to the technical field of a diesel engine test platform, and more specifically relates to a test platform and a control method for a diesel engine starting system. Background technique [0002] During the use of the diesel engine, when it stops running, a small amount of liquid may flow into the cylinder of the diesel engine from the exhaust pipe, especially when the marine diesel engine is in use, seawater may flow back into the cylinder. When there is liquid in the cylinder, the operation of the diesel engine may cause damage to the components in the cylinder. A conventional diesel engine is equipped with a starting system, which can blow air and water before the diesel engine runs to discharge the liquid in the cylinder, and at the same time, the starting system can also provide compressed air for the work of the diesel engine after starting. [0003] However, due to the complexity of the gas pipeline of the ...
