Problems solved by technology

This type of cleaning agent is not ideal for cleaning the carbon deposits in the combustion chamber, especially the carbon deposits on the top of the piston. Since the carbon deposits on the top of the piston are hard carbon deposits, solvent-based cleaning agents cannot be used to effectively clean the carbon deposits on the top of the piston.
Another method is to remove the fuel injector at the 4S shop for cleaning, which is very troublesome, inefficient and takes a long time; by removing the spark plug, inject cleaning agent into the cylinder from the spark plug hole, and remove the carbon deposit on the top of the piston by soaking. This method is time-consuming and labor-intensive, and because most of these cleaning agents are water-based alkaline cleaning agents, the engine oil needs to be changed in time after cleaning. Now, the new type of engine is a direct injection engine in the cylinder, and the engine has no effect on the carbon deposit in the fuel injector. 1. The carbon deposit on the top of the piston is very sensitive, and the fuel injector and the carbon deposit on the top of the piston need to be cleaned regularly
At the same time, since solvent-based injector cleaners can destroy the lubricating oil film on the cylinder wall of direct-injection engines, it is not suitable to use solvent-based cleaners to clean the injectors of direct-injection engines; the traditional method of cleaning carbon deposits on the top of pistons is also It also destroys the oil film on the cylinder wall, which is not good for the direct injection engine

Abstract

A vehicle engine fuel injection nozzle and combustion chamber carbon cleaning device, comprising a fuel provision pipeline having a quick connector (4), and a fuel path port (5) before the engine fuel injection nozzle. Between the quick connector (4) and the fuel path port (5) is inserted a three-way connector (6). The quick connector (4) is connected to a first inlet of the three-way connector (6). An outlet of the three-way connector (6) is connected to the fuel path port (5). A second inlet of the three-way connector (6) is connected to a pressurized cleaning agent tank (7). Between the connection ports of the second inlet and the cleaning agent tank (7) is provided an electronically controlled cleaning agent nozzle (8). The pressure of the cleaning agent in the cleaning agent tank (7) is greater than the supply pressure of the fuel in the fuel supply pipeline. The invention further relates to a vehicle engine fuel injection nozzle and combustion chamber carbon cleaning control method. The cleaning device has a simple structure. The three-way connector in the fuel delivery pipeline can directly mix a cleaning agent with fuel, and the electronically controlled cleaning agent nozzle can dynamically control a mixing ratio, thereby inputting an appropriate amount of cleaning agent while stably maintaining idling of an engine, and within a reasonable cleaning time, realizing a satisfactory cleaning effect with respect to a fuel injection nozzle and a piston top portion.

Description

technical field [0001] The invention belongs to automobile engine maintenance and cleaning, and relates to an automobile engine fuel injection nozzle and a combustion chamber decarbonization cleaning device and method, especially suitable for direct injection engines, and is a non-dangerous fuel injection nozzle cleaning agent used for automobile engine fuel injection Nozzle and combustion chamber decarbonization cleaning application. Background technique [0002] Automobile engine fuel injector cleaning is carried out with the fuel injector cleaning agent at the idle speed of the automobile engine. The traditional cleaning uses a solvent-based cleaning agent with a calorific value, and the cleaning agent replaces the fuel to make the engine run normally at idle speed. Since the cleaning agent has a certain calorific value, the cleaning agent is a flammable chemical, that is, a dangerous chemical, which brings risks in product production, storage, transportation, and use.
