Description
Technical field
The invention belongs to automobile carbon deposition cleaning technology fields, and in particular to one kind is used for the air inlet of gasoline in-cylinder direct fuel-injection engine
The carbon deposit cleaning agent of system.
Background technique
Gasoline in-cylinder direct fuel-injection engine (GDI, Gasoline Direct Injection engine) is equipped with turbine
The gasoline in-cylinder direct fuel-injection engine (T-GDI) of booster is that gasoline is directly sprayed into combustion chamber, does not pass through air inlet port.Vehicle exists
In routine use, since the quality of some oil products has differences and other external factor are such as started although design is very accurate
Inevitably there is carbon distribution in systems, the in-cylinder direct fuel-injection engine intake valves such as machine crankshaft case forced ventilation, exhaust gas recycling, due to
Lack self-cleaning ability, so as to cause a series of engine failure.And the alkene in gasoline can generate in engine
A large amount of carbon deposits, and in fuel tank in also will form colloid, influence the accurate of oil circuit and oil meter.In long-term operational process, into
Air valve and ternary catalyzing unit (containing three-way catalyst in ternary catalyzing unit) can generate obvious or even serious carbon distribution, and (intake valve is heavy
Product object, IVD).
Ternary catalyzing unit is mounted in most important outer purifier in automobile exhaust system, the inside load containing platinum,
The three-way catalyst of rhodium, palladium metal, carbon monoxide, hydrocarbon and nitrogen oxides that vehicle exhaust can be discharged for it etc. are harmful
Gas is changed into harmless carbon dioxide, water and nitrogen by oxidation and reduction.
Intake valve and ternary catalyzing unit (agent) carbon distribution can bring many harm：(1) low-temperature cool starting is difficult, and cold vehicle idling reaches
Less than defined revolving speed, cold vehicle idling can stop working when serious, and idling is low after hot vehicle；(2) engine charge resistance increases, engine
Power decline, causes pinking when serious；(3) driving performance is deteriorated；(4) shortening spark plug, lambda sensor, ternary catalyzing unit makes
Use the service life；(5) gasoline combustion is incomplete, accelerates unsmooth, oil consumption increase, exhaust emissions increase, and the service life of engine shortens.
Common solution has in maintenance using additive or cleaning agent, and cooperates kerosene or aviation kerosine conduct
Retarder thinner can allow driver to feel that the power of vehicle enhances, but this is not the function of additive due to there is the presence of kerosene
Effect, but the effect of kerosene.The ingredient of common cleaning agent has the sub- amide (PIBSI) of polyisobutene fourth two, can clean
Oily device and air throttle and air inlet pipe deposit, but effect is not fine.Polyetheramine (PEA) can also clean carbon distribution, but cost compared with
It is high.And presently commercially available leaning solvent has certain swelling action to the rubber and plastic glue component of pipeline, will affect the sealing of oil circuit
Performance and used life；Commercially available cleaning agent high expensive；Cleaning effect is bad, and cleaning efficiency is low；In particular, existing commercially available clear
Lotion is harmful to three-way catalyst (for example adhere to or cover on three-way catalyst, or inactivate three-way catalyst), influences
The service life of three-way catalyst.
Main engine plants' existing product, market various brands traditional curing product not can effectively solve in-cylinder direct fuel-injection engine into
Air valve carbon distribution problem, and existing commercially available carbon on engine cleaning agent cannot effectively be directed to the air inlet of gasoline in-cylinder direct fuel-injection engine
System is preferably cleaned.It can be in engine after even thering is individual method to need to dismantle engine, or cleaning in cleaning
Interior formation residuals, these all can bring adverse effect to engine.
Therefore, market needs in-cylinder direct fuel-injection engine intake valve cleaning new product safe, disassembly and wash free, that effect is strong.
