14.1 Preparation data
Function of cooling system ：this engine adopts water cooling mode.
cool down high temperature parts with water as the heat absorption medium which then transfers the heat to
the ambient air in order to maintain the optimal working temperature of the engine.
Concrete cooling down circuit： cooling water enters the water jacket of the cylinder through the
crankcase watercourse , passes through the cylinder cover and finally enters the radiator through
piping for heat rejection and transfers heat to ambient air by means of the fins of radiator.
