oil gallery are distributed in timing chain cover. The chain is lubricated by spraying of oil from
nozzle. Forced and splash lubrication system is used for engine. Oil filter is convenient in use
and easy in replacement with a one-assembly structure.
Oil pressure is indicated by an oil pressure switch. When oil pressure is under specified value,
the indicator is on.
3.8 COOLING SYSTEM
Engine is cooled by pressurized circulating water. A centrifugal water pump and a nylon fan
with blades of different lengths are adopted. Results of food radiation, small power loss and small
noise for fan are achieved.
The opening temperature of the paraffin thermostat is at 75°C.
