Welcome to use Gasoline engine.LJ368QA electricity's controlling gasoline engine is our company and the electronics limited company of the consociation car cooperation to develop, Having thenations leads level .The engine adopt technique of the forerunner orders muchin proper order jet, distributor Ignition methodnot touch and explode earthquake control with fromdiagnosis function. Have power of rise big, the oil consume a rate low, thenoise is small andpollute low, the physical volume is small, structure tightly packed etc.Because the engine adopted to shut the wreath feedback type control, candevelop the function of 3 way converts device well, its exhausting can satisfy China ⅳ. The engine forms an organic whole with the gearbox andclutch. The gearbox establishfour drives and one reverse gear, four drives all adopt a synchronousmachine to become soon, operating easy and convenient, do not pound at a noise.Clutch is dry type, Single dial, and diaphragm spring type, structure simple,wear well, separate laborsaving. The engine was applicable to place forerunnerto move a way ago, is the ideal motive of various miniature car, be also the good motive of other engineering machines.

This manual sketches its main property,technical parameter, relevant structure and use of LJ368QA gasoline engine andthe method of maintenance. The main purpose of this manual is to help users to use and maintain the gasoline engine correctly.
