▶ First, the temperature is low, the diesel combustion conditions in the cylinder deteriorate, the fuel atomization is poor, the combustion period after ignition increases, the engine is easy to work rough, aggravate the damage of crankshaft bearings, piston rings and other parts, reduce power and economy.
▶ Second, the water vapor after combustion is easy to condense on the cylinder wall, causing metal corrosion.
▶ Third, unburned diesel may dilute the engine oil and deteriorate the lubrication.
▶ Fourth, the colloid is formed due to incomplete fuel combustion, so that the piston ring is stuck in the piston ring groove, the valve is stuck, and the pressure in the cylinder decreases at the end of compression.
▶ Fifth, the water temperature is too low, the oil temperature is also low, the oil thickens, the fluidity becomes poor, and the oil pump has less oil, resulting in insufficient oil supply. In addition, the crankshaft bearing clearance becomes smaller and the lubrication is poor.
