The diesel engine piston is a key component of the engine, it mainly plays the following important role.
In the working cycle of a diesel engine, the top of the piston is directly exposed to the pressure of high temperature and high-pressure gases generated by combustion in the combustion chamber. This pressure can be as high as several megapascals (MPa), the piston must be able to withstand this enormous force and will be converted into the crankshaft rotation power. If the piston is not strong enough, it will be deformed or even ruptured under high pressure, resulting in engine failure.
The piston is connected to the connecting rod through the piston pin. When the piston moves downward under gas pressure, it transfers the force to the connecting rod. The connecting rod then transmits the force to the crankshaft, causing the crankshaft to rotate. The rotational motion of the crankshaft is the key to the engine's power output. The reciprocating motion of the piston and the connecting rod and crankshaft work together like a delicate mechanical transmission system to convert the linear power generated by combustion into rotary power to drive the vehicle forward or drive other equipment.
The bottom of the piston the piston ring and the cylinder wall closely match and play the role of sealing the combustion chamber. The piston ring has a gas ring and an oil ring. The gas ring is mainly used to seal the high-temperature and high-pressure gas in the combustion chamber to prevent gas leakage into the crankcase. The main role of the oil ring is to scrape the excess oil on the cylinder wall, but also to assist the gas ring in sealing.
As mentioned earlier, the oil ring can scrape off the excess oil on the cylinder wall during the working process of the piston and make it flow back to the oil sump. This can effectively control the consumption of oil to ensure that the engine works within the normal range of oil.
The piston absorbs a large amount of heat generated by combustion during the working process. It transfers the heat from the combustion chamber to the cylinder wall and then radiates the heat through the cooling system (e.g. coolant circulation). This prevents the piston from being damaged due to overheating and ensures that the piston operates within the proper temperature range.
Therefore, choosing a high-quality, high-performance piston is crucial. It not only improves engine performance and reduces the risk of failure, but also extends the life of the engine, reduces the frequency of repairs, and saves maintenance costs.
