Engines that are frequently started and stopped face far greater wear and tear than those that operate steadily for extended periods. This is because each start and stop creates repeated impacts on internal components. During the initial start, oil hasn't fully circulated to all friction points, leaving metal parts in a semi-dry friction state, which is prone to wear. During shutdown, oil backflow causes the oil film on component surfaces to thin or even disappear, requiring re-lubrication upon restart. This repetitive "lubrication-interruption-relubrication" cycle subjects critical components like the engine's pistons, crankshaft, and bearings to continuous impact wear. Over time, this can lead to increased clearances and reduced power.
Engine anti-wear repair agents, with their unique ingredients, effectively protect against the wear characteristics of frequent starts and stops. These repair agents contain active lubricating factors and metal adhesion compounds. Upon engine startup, even before oil circulation is fully established, the repair agent quickly adheres to metal surfaces, forming a temporary lubricating protective film. This protective film works during the semi-dry friction phase of the initial start, reducing direct contact between metal parts and alleviating wear caused by the shock of starting. After the engine is shut down, the special ingredients in the repair agent form a durable, adsorbed protective layer on component surfaces, slowing the loss of the oil film and preparing lubrication for the next start.
The nano-sized repair particles in the engine anti-wear repair agent are excellent at combating repeated impact wear. The impact of frequent starting and stopping can cause tiny scratches and dents on metal surfaces. If left untreated, these damage can gradually expand and worsen wear. The nanoparticles in the repair agent penetrate these micro-damages with the engine oil, filling them physically and chemically through deposition, smoothing the friction surface. This repair action not only reduces the current wear but also repairs existing minor damage, improving component fit and fundamentally minimizing the negative effects of repeated impact.
In actual use, the addition of the engine anti-wear repair agent to engines subject to frequent starting and stopping can reduce wear, as evidenced by multiple indicators. First, engine noise is significantly reduced during startup, due to the reduced impact friction between metal components, resulting in smoother operation. Secondly, after long-term use, the engine's power loss slows down, especially in frequent urban driving conditions. Throttle response is more sensitive, preventing power loss due to excessive wear. Furthermore, the amount of metal debris in the engine oil is significantly reduced, indicating less component wear and better oil cleanliness.
For vehicles frequently used in urban commuting, frequent engine starts and stops are common, making the use of an engine anti-wear repair agent even more essential. Urban roads are plagued by numerous traffic lights and frequent traffic jams, and engines are constantly cycling between starting, idling, and stopping. This makes it difficult for the lubrication system to maintain optimal condition, accelerating the accumulation of component wear. An engine anti-wear repair agent provides additional lubrication protection for these engines, compensating for the lack of lubrication caused by frequent starting and stopping, delaying component aging, extending engine life, and reducing the risk of failures caused by wear.
Used in conjunction with engine oil, the engine anti-wear repair agent creates a dual protection mechanism, further enhancing resistance to wear caused by frequent starting and stopping. Engine oil provides daily lubrication and cooling, while engine anti-wear repair agents provide enhanced protection against vulnerable areas during startup and shutdown, complementing each other. The ingredients in the repair agent also enhance the oil's viscosity-temperature performance, maintaining a stable viscosity during frequent temperature fluctuations during startup and shutdown. This ensures oil film strength and prevents lubrication failure caused by oil viscosity fluctuations, ensuring reliable engine protection under all operating conditions.
When using engine anti-wear repair agents, choose a reputable brand and add them correctly according to the vehicle's manual to avoid excessive use that could affect engine performance. It's recommended to add engine anti-wear repair agent at the same time as an oil change to ensure it mixes better with the new oil and achieves optimal results. For engines already showing signs of minor wear, consistent use of engine anti-wear repair agents over time will significantly improve wear and stabilize engine operation, providing more reliable protection for daily vehicle use.
