Po Fat | [Green Forklift 4Y multi-point EFI gasoline] | Yinchuan 4Y multi-point fuel injection petrol engine supplied by Hefei treasure motive. Our motive is to Hefei Bao Technology Co., Ltd. (www.baufar.cn) located at: Hefei professional: non-road gas engine, petrol engine development, production and sales; forklifts and diesel fuel injection control ECU controls the injector drive time and injection timing LPG Forklift 4Y multi-point EFI gasoline engine, the engine in a variety of conditions can get the best concentration of the mixture. Each cylinder intake port fuel injectors are equipped with a fuel tank fuel pump fuel pump LPG Forklift 4Y multi-point EFI gasoline, the fuel distribution pipe to the fuel pressure regulator allows injection pressure stable fuel injectors per cylinder direct injection into the airway. In each working cycle of the engine (crankshaft twice per revolution) 4Y multi-point fuel injection petrol engine, each cylinder fuel injection time (injection sequence is 1-3-4-2), this spray is called sequential injection. When the engine is running under cold or high-load condition, in order to maintain good performance, ECU open loop control, providing richer mixture; When the engine is at normal operating condition (small load), ECU through the oxygen sensor feedback signals for closed-loop control, to get the best air-fuel ratio, so that three-way catalytic converter to achieve the best cleaning efficiency. ① between "fixed SAS" with the throttle rod into the thickness of 0.45mm thickness gauge. ② Turn the ignition switch ON (but do not start the engine) ③ Loosen the throttle position sensor mounting bolt, and then the throttle position sensor counterclockwise rotation in the end. ④ In this state, the MUT-II "DATA LIST" or ohm meter to check the idle position switch is in the ON position. (Conduction between the 1st and the 2nd terminal terminal) ⑤ slow clockwise rotation green truck 4Y throttle position sensor multi-point EFI gasoline engine until the idle position switch signal from the ON to OFF when you stop (the 1st and 2 terminals No. Terminal nonconductive until the position of that point), the locking in this position of the throttle position sensor fixing bolts. ⑥ connect throttle position sensor connector. ⑦ Check the output voltage of the throttle position sensor. Standard value: 400 ~ 1000mV. ⑧ If the deviation from the standard value, check the throttle position sensor and related wiring harness. ⑨ Remove the feeler. Turn the ignition switch to the OFF position, then remove the MUT-II.
