6, though after the release lever down artificial "shake does not move," crank, but due to the shaking when the flywheel of the diesel engine has been "Save" kinetic energy, Junan tractor, then still driven crankshaft, continued movement of the piston, the piston after the top dead center, the injected diesel happen "spontaneous combustion" phenomenon at high temperatures generated by the compressed gas, tractor prices, thus driving piston, link, crankshaft to the cylinder After the "bottom dead center" direction, tractor, external work, tractor repair, output power, for power is completed, the piston through the lower dead point, the role of flywheel inertial force up dead direction, while the exhaust valves are open at the top cam action, to the outside vent; 3, the engine cooling water temperature should be appropriate. The temperature of the cooling water temperature will directly mark the engine body and affect engine performance. If the engine coolant temperature is too high, deterioration of the mechanical properties of parts, power down, the lubricant thinning, increased wear; conversely, if the engine cooling water temperature is too low, it will affect the quality of the spray injector, resulting in incomplete combustion of fuel completely, friction resistance increases, poor lubrication, easy to make the cylinder liner corrosion, resulting in lack of engine power, increased fuel consumption. Usually cooling water temperature of 80-90 degrees is appropriate. Which is good tractor, tractor, machinery supplied by Shandong Bailong Bailong Machinery Limited.
