How to deal with engine carbon?HS code-driven letter of credit checks Engine carbon is one of the common problems in the process of car use. If it is not dealt with in time, it will affect the performance and safety of the vehicle. So how to remove engine carbon? This article will give you a detailed introduction. I. WhatIt is engine carbonization. Engine carbonization refers to the deposition of a layer of carbon dioxide on the surface of the cylinder, piston head, exhaust valve and other components, resulting in a decrease in engine stability, a decrease in power, an increase in fuel consumption, and even oil burning and other problems. There are many reasons for the accumulation of carbon in the engine, mainly three points: first, the poor quality of fuel, which will produce more carbon pollutants; second, the design problems of the engine itself, such as unreasonable design of the intake channel, oil road and gas road, and excessive intake temperature; third, improper daily maintenance, such as long-term low-speed driving, long-term idling, etc. . II. How to detect engine carbon? In order to avoid unnecessary damage to the vehicle, we need to test and evaluate before removing engine carbon. First of all, the emission of the engine can be checked through the OBD small code reading instrument. If the detection knotThe result shows that the emission parameters of the car exceed the standard, which is likely to be caused by the carbon accumulation of the engine and needs to be cleaned. Secondly, you can check the pollution inside the engine by opening the trottle cover or checking the oil sup. If a large amount of sediment is found, the exhaust pipe and the intake of the variable intake duct and the intake manifold are more obvious. If the emission status of the engine is greatly improved and the fuel consumption and performance are improved, it means that the carbonisation of the engine has been well handled. III. How to deal with engine carbon 1. Hot water cleaning method Hot water cleaning method is one of the relatively simple and effective cleaning methods. First, turn on the vehicle and keep the engine running well, and then pour water of a certain temperature into the heater for 5-10 minutes. When the engine is running, water can be poured into the cylinder to remove the sediment that is not easy to clean.Two. Release agent Release agent Release agent is an additive that can be added to gasoline to remove carbon in the engine. The steps to use the lotion are just to add the lotion with full gasoline and continue to use it according to its instructions. This method is suitable for mild carbon accumulation, but not for more severe carbon accumulation. 3. In-cylinder injection method The in-cylinder injection method refers to spraying the detergent sprayed by the sprayer directly into the cylinder, and the cleaning agent is released from the air gap around the cylinder mouth and tail pipe. This method requires professional operation. During operation, the ignition and fuel feed need to be turned off, and the cleaner need to be sprayed inside the cylinder needs to be cleaned. Four. The incineration method is to spray the car fuel mixture into the car, which can be used to clean the cylinder and exhaust system. The method is to spray a clean fuel mixture inInside the engine, then start the vehicle and maintain continuous operation, let the mixture burn out to achieve the effect of cleaning the engine. In summary, cleaning engine carbon is a necessary task to maintain the normal operation of the car, which can effectively improve the performance and reliability of the engine and reduce carbon dioxide emissions. However, when choosing a cleaning method, you must pay attention to the fact that different degrees of carbon accumulation in different vehicles are suitable for different types of cleaning methods, so you should choose a certified professional institution for cleaning.
