Diesel engine propulsion system

Abstract

The invention discloses a diesel engine propulsion system which comprises a diesel engine empty car starting module, an idle running operation module, a run-in and run-out process module and a navigation and steering module. The diesel engine empty car starting module, the idle running operation module, the run-in and run-out process module and the navigation and steering module are respectively used for simulating an operation process of a diesel engine. The system is in communication with an emulation computer through an emulation interface device and is used for achieving debugging or testing of a device for a ship. The system can be used for laboratory test on equipment such as a diesel engine electronic speed adjusting device for the ship through the emulation interface device, and the system has the advantages of being good in real-time performance, abundant in function and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, and in particular relates to a diesel engine propulsion system. Background technique [0002] At present, most marine diesel engine governors use digital electronic governors based on software programming. Due to the introduction of digital control, nonlinear factors caused by quantization error, rounding error and additional time delay will inevitably be brought. Therefore, online testing must be carried out for the dynamic characteristics of diesel engines under transient conditions before marine governors are developed and delivered. The two existing methods for ESC testing are as follows: [0003] 1. Carry out parameter setting and performance testing of the electronic governor directly on the marine diesel engine test bench; [0004] 2. Carry out the parameter setting and performance test of the electronic governor through the computer simulation test device. [0005] The main pro...

Problems solved by technology

[0005] The main problem of the first test technology is that the on-site test of large diesel engines is not easy to operate, the long-term test will inevitably cause a lot of energy consumption, and the test cost is high

Although the second test technology can solve the economic problem of the test, because the simulation system model is too simple, it can only simulate the average speed change of the system, and cannot simulate the real starting process and instantaneous speed of the diesel engine, and the simulation is quite different from the actual one.
