Q:What is the high and low pressure circuit of diesel engine?

High pressure oil from the pump to the diesel engine combustion chamber nozzle before that, due to the movement of the piston engine in the process of pressurized environment into the combustion chamber of diesel oil injection so the pressure is high, the combustion chamber is higher than the minimum compression pressure environment stroke made, otherwise the oil can not be sprayed into the combustion chamber. So this section of the road is made of metal.
