Most special vehicles, includingထရပ်ကားတပ်ဆင်ထားသောကရိန်း၎, typically utilize diesel as their fuel source, although a minority might employ gasoline or electricity. The quality of the diesel fuel employed has a direct and significant impact on the performance and longevity of the engine within theထရပ်ကားတပ်ဆင်ထားသောကရိန်း. Poor-quality diesel, contaminated with moisture or impurities, can potentially inflict severe damage on the high-pressure distribution pump. ဒီနေ့, let’s delve into the maintenance aspects ofထရပ်ကားတပ်ဆင်ထားသောကရိန်းs that pertain to fuel.
Both the air filter and the fuel filter have a direct bearing on the quality and flow of fuel. When the fuel of theထရပ်ကားတပ်ဆင်ထားသောကရိန်းcontains a certain proportion of impurities, it can lead to obstructions within the fuel line. Such blockages can present challenges in starting the engine, cause the engine to shudder upon startup, disrupt the air-fuel ratio balance, result in suboptimal combustion, emit black smoke, and in extreme cases, may also cause harm to the high-pressure pump and fuel injector. ထို့ကြောင့်, it is imperative to ensure the regular cleaning and maintenance of these filters. The following points need meticulous attention and execution:
Strengthen the maintenance of the filter
First and foremost, it is crucial to ensure the quality of the fuel by refueling at established and reputable gas stations. The diesel filter serves as the final line of defense for the fuel system. In comparison to traditional fuel system technologies, the common rail system demands greater precision and necessitates high-quality, specialized fuel filters designed for this system. Poor-quality fuel filters present several significant hazards:
Insufficient rated power can lead the filter to operate beyond its designed capacity, thereby straining the fuel system and adversely affecting the vehicle’s power performance and the lifespan of the fuel system. This can result in reduced engine efficiency and potential breakdowns.
The filter paper with large and uneven pore sizes, a small surface area, and low filtering efficiency can accelerate the early wear of the fuel system and the engine. Inefficient filtration allows harmful particles and contaminants to pass through, causing abrasive damage and reducing the overall performance and reliability of the engine.
Ineffective oil-water separation can lead to the corrosion of fuel components and the engine. Moisture in the fuel can cause rust and deterioration of metal parts, compromising the integrity and functionality of the fuel system and engine.
An insecure internal bonding of the filter or a faulty seal can result in a short circuit of the filter element. This prevents the effective filtration of impurities, leading to the direct passage of contaminants into the fuel system and the engine, causing accelerated wear and potential malfunctions.
During the operational lifespan of theထရပ်ကားတပ်ဆင်ထားသောကရိန်း, it is essential to enhance the maintenance of the air filter, oil filter, diesel filter, and other related filters to ensure they function optimally. ပုံမှန်စစ်ဆေးခြင်း။, cleanings, and replacements as per the manufacturer’s recommendations are necessary to safeguard the engine and fuel system from damage and ensure efficient performance.
The truck-mounted crane cannot idle for a long time
The prolonged idling of theထရပ်ကားတပ်ဆင်ထားသောကရိန်းcan have detrimental effects on the quality of fuel injection atomization and accelerate the early wear of the cylinder wall. The quality of atomization is intricately linked to the fuel injection pressure, the aperture of the injector, and the speed of the camshaft. Since the injector aperture remains constant, the quality of fuel atomization predominantly depends on the fuel injection pressure and the camshaft speed. A slower camshaft speed leads to a prolonged rise in fuel injection pressure, thereby deteriorating the quality of fuel atomization. The camshaft speed is directly influenced by the rotational speed of the diesel engine. Prolonged idling causes the temperature within the diesel engine’s combustion chamber to drop excessively, resulting in incomplete combustion. This incomplete combustion can lead to the accumulation of carbon deposits that might clog the injector nozzles, cause issues with the piston rings, or jam the valves. ထို့ အပြင်, the incompletely combusted diesel can wash away the protective oil film on the cylinder wall and dilute the engine oil, thereby compromising the lubrication of engine components and accelerating the premature wear of these parts. ထို့ကြောင့်, it is advisable to limit the idling time of theထရပ်ကားတပ်ဆင်ထားသောကရိန်းto approximately 10 minutes.
Long periods of idling not only waste fuel but also contribute to increased emissions and engine wear. Frequent short stops and extended idling can lead to a build-up of deposits and reduced engine efficiency over time. By minimizing idling and ensuring the engine operates at an appropriate speed for the given conditions, the lifespan and performance of the engine can be significantly enhanced.
နိဂုံးချုပ်အားဖြင့်, maintaining the fuel system of a ထရပ်ကားတပ်ဆင်ထားသောကရိန်းrequires a combination of using high-quality fuel, ensuring the proper functioning and maintenance of filters, and avoiding prolonged idling. By adhering to these practices, the reliability, performance, and longevity of theထရပ်ကားတပ်ဆင်ထားသောကရိန်း‘s engine can be safeguarded, reducing the likelihood of breakdowns and optimizing operational efficiency.
