Process without opening cylinder for quickly removing carbon deposition of combustion chamber of engine

Abstract

The invention relates to a process without opening a cylinder for quickly removing carbon deposition of a combustion chamber of an engine. An agent-added gasoline tank with an embedded electric fuel pump is filled with the agent-added gasoline that is mixed by a fuel cleaning agent and a regular vehicular gasoline; the tail end of an oil outlet hose of the oil tank is connected with a quick joint;the quick joint is hermetically connected with an oil pressure detecting hole of a cleaned engine fuel main pipe; the cleaned engine is started and the electric fuel pump in the oil tank is started subsequently so that the crude gasoline and the agent-added gasoline are supplied to the engine simultaneously; when the engine stably runs at a special working condition, the supply of the crude gasoline is cut so that the oil is singly supplied by the agent-added gasoline; the openness of the choke is gradually enlarged till the large load working condition occurs; and when the engine does work by combustion, the deposition carbon in the combustion chamber is decomposed and is exhausted along with the exhaust gas after being combusted and gasified. Without opening the cylinder of the engine,the severely deposited carbon in the combustion chamber is quickly removed till the original working performance of the engine is recovered; and the parts of the engine are not damaged in the whole cleaning process.

Description

technical field [0001] The invention belongs to the technical field of automobile repair and maintenance, and relates to an engine cylinder-free fast cleaning process, in particular to a cylinder-free rapid cleaning process for deposit carbon deposits in an engine combustion chamber. Background technique [0002] People in the industry know that as the mileage of a car increases, deposits and carbon deposits will form in the combustion chamber of the engine. Practice shows that a small amount of carbon deposits can help improve engine power and fuel economy, but a large amount of carbon deposits will have a great impact on engine performance. Not only the power and fuel economy are seriously reduced, but the hydrocarbons in the exhaust Compounds HC and nitrogen oxides NOx are seriously deteriorated, and carbon deposit knocking interference occurs, which deteriorates engine cold start performance. Therefore, after the carbon deposition in the combustion chamber reaches a cer...

Problems solved by technology

[0005] Apparently, the above-mentioned manual removal method is not only time-consuming and labor-intensive, but also inefficient, especially causing great damage to the engine itself, which greatly shortens the design life of the engine.

And often because the combustion chamber is cleaned too clean, it will reduce its sealing performance, which will lead to a decrease in the power performance of the engine, and ultimately affect the performance of the vehicle.
