Oxyhydrogen carbon removing method for automobile engine

Abstract

The invention discloses an oxyhydrogen carbon removing method for an automobile engine, and aims to overcome the shortcomings that cost is relatively higher, that a cylinder wall and a piston ring may be corroded, that effluents may contaminate an environment and that the concept of removing carbon by an oxyhydrogen mixture is lack of specific technical means and cannot be actually applied in theprior art. Key points of the technical scheme are that: the method is characterized by comprising the following steps of: checking that the machine oil and petrol reserves of an automobile are normaland that running is normal, checking the carbon deposition conditions of a cylinder of the engine from a spark plug hole by using an endoscope, detaching an automobile brake vacuum pipe or a waste pipe, connecting an oxyhydrogen mixture supply pipeline, starting running an oxyhydrogen mixture generation device, starting the automobile engine, slowly opening a gas supply valve for the oxyhydrogen mixture at idle speed, stopping adjusting the gas supply valve when the rotating speed of the engine is increased to 1,200 to 2,000 revolutions per minute, exhausting white vapor or black water drops after the engine is run for 8 to 12 minutes, closing the gas supply valve after the engine is continuously run for 28 to 60 minutes to remove carbon, and pedaling an automobile accelerator to blow thecarbon removal effluents out of the exhaust pipe.

Description

technical field [0001] The invention relates to automobile maintenance and repair technology, in particular to a method for decarbonizing automobile engine cylinders by using hydrogen-oxygen mixture. Background technique [0002] After the car engine has been running for a long time, the insufficiently burned fuel or the deteriorated engine oil will form carbon deposits in the engine cylinder, also known as the accumulation of oil dirt. Large and poor dynamic performance, carbon removal is the solution to this problem. At present, the carbon removal of automobile engines can generally be carried out when the engine is disassembled during the overhaul of the automobile. This method is generally not carried out when the engine is not disassembled, and the cost is very high; In normal working condition, a foam of a corrosive chemical agent is slowly introduced into the engine cylinder for cleaning. The disadvantage of this method is that the corrosive chemical agent will corro...
