Cleaning agent for carbon deposition in valve combustion chamber

At present, there are several methods to clean the carbon deposit in the valve combustion chamber: 1. If there is too much carbon deposit, it is best to spray cleaning liquid from the spark plug hole to clean the carbon deposit in the combustion chamber. Use special equipment to pump a good carbon remover into the combustion chamber from the spark plug hole, so as to melt the carbon deposits in the combustion chamber, and then suck these liquid carbon deposits out of the spark plug hole. This method is the best at present, and the price is around 800 yuan. 2, if it is not too much, you can use the method of hanging bottles for cleaning, and the cost is about 300-500 yuan; 3. Fuel injectors can be cleaned by hanging bottles. As for the throttle, check it every 10000-20000 km. If it is polluted, it should be cleaned up in time, and the cost is about 50- 100 yuan.
