Abstract

The invention discloses an oil injector detecting system. The detecting system comprises an electrical performance detecting module, a physical performance detecting module, an intelligent terminal, and an observing module. The physical performance detecting module comprises a microprocessor, an oil pressure control unit, and an oil injector driving unit. The microprocessor is connected to the intelligent terminal and setting operating condition parameters of the injector to be detected under the control of the intelligent terminal. The oil pressure control unit is connected to the microprocessor, and controls the oil pump to supply or drain the oil according to the preset injection pressure under the control of the microprocessor. The oil injector driving unit is connected to the microprocessor, and controls the oil injector driving unit to drive the oil injector to be detected to realize the thin layered injection of the oil according to the type of the oil injector to be detected under the control of the microprocessor. The observing module is connected to the microprocessor via the intelligent terminal, and assists the uniformity / atomization observation of the oil injector to be detected under the control of the microprocessor and output physical performance detection data to the intelligent terminal. According to the oil injector detecting system, the automatic detection level of the detecting system is improved, and the detecting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle power system detection, in particular to a fuel injector detection system. Background technique [0002] Gasoline Direct Injection system (GDI) has advantages in terms of power performance, fuel economy and emission environmental protection, and it is more and more widely used in the field of automobile power system. The fuel injector is the core component, and its life cycle performance directly determines the life cycle performance of the engine. At the same time, with the improvement of environmental protection requirements, liquefied natural gas (Liquid Natural Gas, LNG) / compressed natural gas (Compressed Natural Gas, CNG), as an environmentally friendly, efficient and economical new energy fuel, is more and more widely used in high-power engines such as engines. field. [0003] At present, because existing GDI injectors rely more and more on lean stratified injection, existing injector insp...
