【Why Need It】The performance of the injector plays a vital role in the power of each engine. Due to the fuel quality, the injector cannot work normally, causing serious carbon deposits in the cylinder; accelerating the cylinder bore and piston ring, causing unstable idling, increased fuel consumption, weak acceleration, difficulty in starting, excessive emissions, and complete blockage of the injector. Cause damage to the engine, so the injector should be cleaned regularly.

【Digital Display】With the help of microcomputer control and digital display, the equipment makes possible automatic cleaning, testing injectors and real-time monitoring of the dynamic values.

【Automatic Cleaning and Testing】Fuel pressure control through microcomputer offers stable pressure control and largeadjustable range, which is suitable for all EGI vehicles and can help to achieve automatic cleaning and testing of injectors.
