Single-cylinder electronically controlled fuel injector test platform for marine low-speed engine

Abstract

The invention discloses a single-cylinder electronic fuel injector test platform for ship low-speed machines. The single-cylinder electronic fuel injector test platform comprises an electronic fuel injection module communicating with an ECU, a cooling system connected with the electronic fuel injection module, an oil quantity measuring mechanism connected with the cooling system, a PLC communicating with the oil quantity measuring mechanism, a weighing module connected with the oil quantity measuring mechanism, a servo motor communicating with the PLC, and a test platform measuring and controlling module. The electronic fuel injection module, the PLC, the weighing module, and the servo motor communicate with the test platform monitoring and control module. The single-cylinder electronic fuel injector test platform has an advantage that the speed simulation of the servo motor fully satisfies a speed demand of the ship low-speed machine, can measure the fuel injection quantity of a third-party fuel injector in every cycle, can measure respective performance parameters of the fuel injector, and provides direction for the control strategy and optimization coordination of the low-speed machine.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine engineering, in particular to a single-cylinder electronically controlled fuel injector test platform for marine low-speed engines. Background technique [0002] Marine diesel engines have the characteristics of high power, harsh working environment, poor fuel quality and long running time, and the implementation of Tier III emission standards of the International Maritime Organization and the depletion of fossil energy have put forward stricter requirements for various performance indicators of marine diesel engines. At present, the emission control of marine diesel engines mainly relies on the internal purification technology. Fuel injection technology is the core of in-machine purification technology. There are more and more marine low-speed intelligent diesel engines with electronically controlled fuel injection as the core in foreign countries. my country's research on mar...
