With the popularity of gasoline and diesel engines, more and more people realize the necessity of engine cleaning. The engine is the core of the whole car. If the engine is not well maintained, its life will be greatly shortened. Cleaning the engine is one of the necessary procedures, which plays a great role in the performance and service life of the engine. Today's article will introduce in detail how to use diesel to clean the engine. I. The principle of cleaning the engine. The first thing you need to understand is the principle of cleaning the engine. Because of the operation of the engine, a large amount of carbon, oil scale and other dirt will be produced. These sediments willAttached to all parts of the engine, it affects the temperature, pressure, transmission and cooling of the engine, resulting in engine instability, abnormal noise, slow acceleration, insufficient power and other problems. These problems begin to appear when the carbon accumulation of the engine reaches a certain level, so it is very necessary for every car owner to clean the engine regularly. II. Step 1 of diesel cleaning engine. When choosing a suitable diesel engine to clean the engine, you should use pure and impurity-free diesel, and it is best not to use diesel with additives. Because additives may cause damage to the engine, they cannot be cleaned during the cleaning process. Two. Prepare cleaning tools. Before cleaning the engine, you need to prepare some tools first. The tools include a spray bottle, a barrel of pure diesel, a soft brush and plastic gloves, etc. 3.To load the diesel, put the pure diesel into the spray bottle. Remember not to tighten the stopper too tightly to avoid deformation of the bottle when spraying diesel. While adding diesel, you need to hold down the nozzle on the mouth of the bottle until the diesel flows out of the nozzle and remove the air. Four. Add diesel to open the hood of the car, find the air intake of the engine, and spray the diesel evenly at the air intake with a diesel spray bottle, so that the diesel can flow into the engine along the intake pipe. After spraying the diesel, you need to wait for 5 minutes so that the diesel can play a cleaning role in the engine. 5. Use a soft brush to clean. When waiting for the diesel to clean the engine, you can use a soft brush to clean the carbon and other sediments on the surface of the engine. According to personal preferences and the severity of the engine condition, you can choose different degrees of cleaning force to clean the engine. 6. After starting the engine and waiting for a period of time, you can start the engine to clean the diesel in all parts of the engine.After starting the engine, let the car idle until all the sprayed diesel is burned. 7. Test the engine performance. After cleaning the engine, it is necessary to test to check whether the performance of the engine has improved. First, check whether the noise of the engine is significantly reduced, and secondly, check whether the acceleration is more stable and whether the engine sound is softer. If you find that the performance of the engine has not been improved or there is an abnormal situation, please contact professional and technical personnel in time for in-depth troubleshooting. III. Things to pay attention to when cleaning the engine 1. Diesel spray evenly: When spraying diesel, it is necessary to pay attention to spray the diesel evenly to avoid excessive spraying of a certain part of the diesel, resulting in the residue in the cleaning area of the engine. Two. Control of adding diesel: When cleaning the engine, the amount of diesel applied should not be too much, otherwise the diesel will be sprayed too much into the exhaust system, resulting in pollution of the exhaust system and unpleasant smell.3. Pay attention to safety: When cleaning the engine, pay attention to safety to prevent diesel splashing on the body, cause skin allergies or combustion accidents. Wear enough protective clothing, gloves, glasses, masks and other protective equipment. Summary: Through the introduction of this article, we can clearly know how to use diesel to clean the engine and the precautions for cleaning the engine. Although cleaning the engine is relatively simple, it needs to pay attention to many details. If it is not operated properly, it is easy to cause many problems. Therefore, it is recommended that car owners need to use professional cleaning tools and methods when cleaning the engine, or seek professional guidance and help to ensure the long-term stable performance and life of the engine.
