What is the difference between four-stroke and two-stroke engines?

The differences between four-stroke and two-stroke engines lie in their structure, working process, lubrication methods, and fuel consumption. The structural differences and functions are as follows: Structural differences: The two-stroke engine mainly consists of components such as the cylinder head, cylinder, piston, and piston rings, with intake ports, exhaust ports, and scavenging ports opened on the cylinder block. Function of the four-stroke engine: During the intake stroke, the intake valve opens and the exhaust valve closes. The piston moves downward in the cylinder, drawing fresh air into the cylinder.

What Causes German Cars to Burn Engine Oil?

Due to the unique oil storage structure of German car engines, the reasons and solutions for oil burning in German cars are as follows: Reasons: The oil storage structure of German car engines is different, employing a design similar to a mesh pattern. This allows the cylinder walls to absorb more engine oil, facilitating the formation of an oil film during piston ring movement. The valve is essentially designed to prevent oil from leaking into the combustion chamber. However, over time, wear and aging are inevitable. The valve's function is to prevent oil from seeping into the combustion chamber, but prolonged use leads to wear and aging. Solutions: If abnormal oil consumption is detected, it is advisable to have the vehicle inspected and repaired at a service center, including the replacement of the oil filter.
