2.Patent technology-With independent lubricating oil cooling water pipe to control engine oil temperature, to prevent spare parts from abrasion caused by high-temperaure engine oil;
3.Larger capacity engine oil sumpat the bottom of crankshaft case, oil lubricating more effcient
4.With start depressurization system, easy to start;
Main performance features
New large box:
The water-cooled engine 300 increases the space of the middle tank greatly, the gas convection in the tank is more smooth, the oil temperature is significantly lower than that of the ordinary engine, and the oil filling volume is 1600ml;
Optimize the transmission system, widen and strengthen the main and auxiliary shafts of each gear and wear-resistant clutch to improve the reliability of the transmission system;
Heat engine optimization and strengthening:
the cylinder body is made of all cast iron, which improves the reliability of the heat engine;
Optimize the cooling system:
The cooling system adopts the impeller with large pump water volume, which makes the temperature of the whole machine greatly reduced;
Optimize the exhaust gas circulation system:
Double gear cover and cylinder head cover exhaust gas circulation balance system is adopted for the exhaust gas circulation of the whole machine;
Optimize the clutch mechanism:
The clutch adopts carbon fiber friction plate, pressure plate with steel plate structure, center sleeve and clutch with damping spring to improve the backup coefficient and reliability of the clutch.
