Water channel, at this moment water outlet water temperature is also higher, cooling into cooling water tank 23, this function is completed by cooling fan blade 24.Cooling water
Water pump is sucked again after cooling water tank is cooling, so on circulate, when water tank temperature is excessively high since pressure increase can open water
The water of spilling is flowed into deputy tank water filling port 40 by the check valve on case water filling port 26, can generate negative pressure upon a drop in temperature, and logical
Reversing valve is crossed to add to the cooling water of deputy tank in water tank.
Alternator assembly is mounted on the output end of crankshaft 22, and stator 31 is fixed on the inner cavity of right case 1, rotor 30 and crankshaft
22 connections, revolving speed is higher, and generated output is bigger, and engine assembly revolving speed declines therewith when the load is decreasing.Alternator assembly
Cooling is solved by the force(d) (draft) fan 15 in supercharging air pump 14.Force(d) (draft) fan 15 is fixed on rotor 30, output power
When increase, revolving speed is increased accordingly, and temperature rise can be higher, and the raising of 15 revolving speed of force(d) (draft) fan also increases cooling air quantity.
The lubrication of conventional general gasoline engines is solved by splashing machine oil, although simply, effect is poor, revolving speed is not yet
It can improve.The machine is equipped with lubricating oil pump 20, and the pressure oil that lubricating oil pump 20 pumps out enters 22 connecting rod of crankshaft through dedicated oil duct a part
Major part, lubricates needle bearing, cylinder wall and piston 29 on connecting rod, and another way enters the rocker arm chamber of cylinder head 4, both has lubricated portion
Part, and flow back into crankcase certainly after taking away a part of heat, it is drawn into lubricating oil pump 20 again using oil filter 18.
