Structural Characteristic of Engine Engine and Engine are new products based on the features
of domestic. overseas same type engine and the modern up-to-date engine technologies It applies the technologies of
electronic control fuel multipoint sequence injection, group ignition, and close-ring control system provided by the United
Automobile Electronic of Shanghai (UAES). The multipoint sequence injection guarantees that the combustible gas
mixtures are produced in different cylinders under identical conditions, so as to improve the mixture quality; the ECU
updates and selects the best injection timing, producing highly precise control of fuel quality. It’s structured without power
distributor and with 2 ignition coil that can generate voltage as high as 10 to 35kV for ignition.
With the overall displacement of and . engine and engine are cylinder-in-line,
water-cooling. 4-stroke gasoline engines equipped with double over head camshaft, 16 valve, and electronic control fuel
injection. There’re the oxygen sensor and the three-way catalytic converter in the exhaust pipe. ECU controls the switch of
cooling fan in the engine according to the change of cooling water temperature in order to keep the cooling water in normal
temperature. Fig. 2 and Fig. 3 are the assembly drawing and the components assembly drawing of engine. Fig.
4 and Fig. 5 are the assembly drawings of engine with power system and auxiliaries respectively.
Fig. 6 is the layout of electronic control fuel injection system in engine.
