How can diesel engines be more fuel-efficient?(一)

2021-08-19


If a diesel engine malfunctions, regardless of the size of the malfunction, it will reduce the efficiency of the diesel engine and increase fuel consumption. Therefore, serious maintenance of the diesel engine, and the problem should be repaired immediately, is one of the effective ways to reduce diesel engine oil consumption (fuel consumption and oil consumption). To make the diesel engine fuel-efficient operation, the following points need to be done.
 
1)Maintaining the best condition of diesel engine valve clearance is one of the basics of diesel engine fuel saving.If the valve clearance of the diesel engine is not correct, it will cause insufficient intake and unclean exhaust, which will inevitably result in a small excess air coefficient of the diesel engine, resulting in incomplete fuel combustion. As a result, not only the lack of power of the diesel engine, the appearance of black smoke and other operating failures, but also a significant increase in fuel consumption. Therefore, it is necessary to check the valve clearance regularly.

2)Maintain the best fuel supply advance angle. For example, the best angle of fuel supply advance angle for 195 diesel engine is 16°~20°.When the diesel engine is used for a period of time, due to the wear of the plunger fittings and the transmission parts of the fuel injection pump, the fuel supply advance angle will decrease, causing the fuel supply time to be too late, and the fuel consumption increases. Therefore, it is necessary to ensure that the fuel supply advance angle is at the best angle.

3)Avoid diesel engine oil leakage. There is oil leakage or oil leakage in the fuel system. Although it may not be serious, it will cause considerable fuel loss over time.

4)Ensure that the cylinder assembly is always in the best working condition. If the cylinder components are worn, the compression pressure of the cylinder will decrease, which will inevitably lead to a worsening of the fuel combustion environment, which will significantly increase fuel consumption.

5)Change the "big horse-drawn cart" approach. Many equipment has a "big machine with a small load, which is a waste of energy. The improvement method: appropriately increase the diesel engine pulley, and increase the equipment speed when the diesel engine is running at a reduced speed, so as to achieve the purpose of power increase and energy saving.
