Application number is that 201210021841.1 patent of invention relates to and a kind ofly administers that motor vehicle exhaust emission exceeds standard and the integrated approach of fuel-economizing, adopts engine depth maintenance scheme, in lambda sensor maintenance or ternary catalyzing unit maintenance more than two or two; Engine depth maintenance is that harmless static state is exempted from the mode of tearing open and removed carbon on engine, adopt the foam method of water-based band alkalescence, and special device is removed carbon on engine; The mode of cleaning and activating lambda sensor of pulling down is adopted in the lambda sensor maintenance, and the solution lambda sensor is blocked and lost efficacy and the poison deactivation problem; Ternary catalyzing unit do not lose efficacy and nonclogging situation under, adopt the ternary catalyzing unit washing agent to remove its surperficial sulphur phosphorus and complex compound; In the situation that ternary catalyzing unit stops up, first pull down ternary catalyzing unit, then clean and dispel its surperficial all complex compounds with the ternary catalyzing unit washing agent, guarantee that ternary catalyzing unit is unimpeded, then, with the activation of ternary catalyzing unit activator, recover its catalysis.This scheme can only of short duration removing motor carbon distribution and greasy filth, can not solve the engine chamber wearing and tearing that the friction of cold start-up cylinder causes, can not solve marginal lubrication problem, can not realize maintenance long-lasting of lambda sensor and ternary catalyzing unit.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of long-acting cleaning maintenance method of motor car engine and air inlet system and exhaust system, can not change under the structure prerequisite of motor, solve the engine chamber wearing and tearing that the cold start-up dry friction causes, solve marginal lubrication problem, realize maintenance long-lasting of lambda sensor and ternary catalyzing unit; To present stage the huge vehicle exhaust problem of exceeding standard carry out effectively administering and improving, cost is relatively low, to the user, does not bring extra burden can permanently effectively reach automotive emission again qualified.
In order effectively to reduce the discharge of engine exhaust harmful gas, the Combustion Process Control of motor and the external control of motor are crucial.The purpose of the Combustion Process Control of motor is to allow ignition mixture in cylinder fully burn.Guarantee abundant burning, except require accurately to control well inflammable mixture concentration (injection mode, air-flow control etc.), also to have enough velocity of combustion and period of combustion (igniting opportunity and valve timing control etc.).
The external control object of motor comprises toxic emission cleaning system, the contents such as engine lubrication system, fuel oil quality.
One, toxic emission cleaning system is analyzed:
The motor vehicle gasoline engine exhaust emission cleaning system of take is example, and normally ternary catalyzing unit works, and the raising of engine lubrication system maintenance and fuel oil quality is also the key that reduces the exhaust emission pollution discharge.
In order further to reduce CO, HC, NO in engine exhaust
XDischarge amount, the modern gasoline machine is generally installed purification plant in releasing system, above-mentioned three kinds of harmful gases are carried out to purified treatment, this purification plant is called triple mode catalytic converter.In order to effectively utilize triple mode catalytic converter to exhaust catalytic purifying usefulness, must adopt the feedback signal of lambda sensor, chemically correct fuel (A/F value) is carried out to accurate feedback control.
It is the recurrent fault of motor that lambda sensor lost efficacy, the reason and the fuel oil quality that have caused lambda sensor to lose efficacy, lubricant oil, condition of road surface has very large relation, because Chinese sulphur content of fuel oil is high, and use and contain manganese antiknock agent MMT, ethanol petrol is used in some areas, lubricant oil is used sulfur-bearing, phosphorus antioxidant, the reasons such as congestion in road, one section mileage rear engine lambda sensor of automobile running will produce sulphur phosphorism problem, the carbon monoxide poisoning problem, the poisoning problem of manganese deposition thing, cause engine air-fuel ratio feedback control three-way emission control system cisco unity malfunction, oil consumption increases, power descends, discharge exceeds standard.
Another motor is in the process of using, and long-time running will cause triple mode catalytic converter to stop up, when the exhaust triple mode catalytic converter nature that lost efficacy again that has some setbacks can exceed standard by engine exhaust emission.
Two, engine lubrication system analysis:
After engine cooling, machine oil has been got back to oil sump, high engine speeds running while again striking sparks, and lubricant oil can not reach the parts friction surface moment, caused the dry friction between parts, although such dry friction just in a flash, the amount of friction caused causes more than 60% of automobile wearing and tearing.And the most of reason that causes dry friction is the two large killers that generally acknowledged by industry due in engine lubrication system: greasy filth and carbon distribution.Greasy filth and carbon distribution can make engine consumption increase, and power reduces, and discharge exceeds standard.
1, the generation of greasy filth:
While in motor, using I. C. engine oil, the city automobile recoverable amount is more and more higher, causes urban highway traffic crowded, and automobile often is in the state of low-speed running.Now the imperfect combustion Fuel Petroleum of part enters crankcase, generates with the further oxidation of I. C. engine oil, condensation, has so just produced greasy filth.Modern motor all is furnished with crankcase vent valve, is responsible for the pressure of balance crankshaft case when engine running.By engine oil impurity, after greasy filth etc. partly or completely stopped up, the discarded and water vapour of crankcase inside can not be discharged in time when crankcase vent valve, and after chemical reaction, just caused the generation of greasy filth, and produce vicious circle, and greasy filth is more and more serious.
Greasy filth is a kind of colloid substance of strong adhesion, mainly appear at each parts of crankcase inwall, each parts of cylinder head camshaft surrounding, the time rule lids near on each parts.Machine oil is as the important oiling agent of engine interior, if greasy filth too much blocks oil duct, will cause parts to lose lubricated excessive wear and scrap.
2, the formation of carbon distribution:
(1) in engine work, gasoline and normally enter the engine motor oil of firing chamber, under the condition of hypoxia, can not perfect combustion in cylinder, produce the particulate that oil smoke and lubricant oil burn; When motor remains in operation, further be subject to oxidation and become colloid, be bonded at securely on piston top, on piston ring, the valve back side, the suction tude inner face, in throttle body and firing chamber etc.; Under the repeated action of high temperature, again colloid is become to asphalitine, resinite and carbonaceous, thereby form carbon distribution;
(2) crankcase ventilation setting.For preventing contaminated air, the cylinder waste gas (HC) of altering of engine interior is directly introduced to intake manifold, along with entering firing chamber together, fresh air burns.The oily vapours of high temperature is full of intake manifold with fresh air, and a part is attached to tube wall and valve back and forms carbon distribution, and another part is mixed to form mixed gas at the intake valve place with the fuel oil sprayed into inlet stream, is discharged from outside car after entering combustion chambers burn;
(3) gasoline is in storage, transportation process, easily and air generation oxidation reaction, generate colloid substance, perhaps the content of the colloid of gasoline own is with regard to very high (gasoline quality is poor), fuel oil supply system by vehicle enters inside, firing chamber to these colloids with gasoline, then, after with gasoline, together burning, will make the positions such as firing chamber, piston ring groove, spark plug, intake valve back, intake duct of oil sprayer, motor in fuel oil supply system produce a lot of carbon distributions and greasy dirt etc.;
(4) urban traffic situation blocked up, make vehicle be in all the time the state loitered, motor can not high rotation speed operation, fuel oil or the also absolutely burning of lubricant oil of scurrying into firing chamber, unburned part oil plant forms colloid under the effect of high temperature and oxygen, stick on the part surface of engine interior, then form carbon distribution through high temperature action;
(5) position of inflammable mixture formation, the outer electronic fuel injection engine of spraying of cylinder is controlled characteristics, inflammable mixture forms at the inlet manifold place of cylinder outside, because the structural feature of motor is attached on intake valve and chamber wall the part oily vapours, wax and colloidal material in gasoline have but stayed, if things go on like this wax in gasoline and colloidal material are more long-pending thicker, and the rear hardening of repeatedly being heated has just formed carbon distribution.
It is inevitably that engine operation produces carbon distribution and greasy filth etc., but will cause engine operation bad when carbon distribution is too much in motor, produces different phenomena of the failure, causes motor vehicle exhaust emission not up to standard.
Three, fuel oil quality analysis:
Not as more external developed countries, the colloid in oil product and asphalitine can be stayed filter cleaner by an oil supply system part and cause fuel path not smooth due to the fuel oil quality of China, the operating mode reduction of motor, incomplete combustion; A part enters engine chamber, these colloids and asphalitine when incomplete combustion occurring, can sintering on oil nozzle and valve, vicious circle appears, power descends, discharge exceeds standard.
