Description
Technical field:
The utility model relates to a kind of car engine air admittance valve carbon deposit laboratory pick-up unit.
Background technology:
The development of advancing by leaps and bounds along with auto industry and the rapid increase of cities and towns flow motor, motor vehicle exhaust emission causes that atmospheric pollution causes serious threat to the people's health and environment.For realizing " headroom blue sky brings benefit to the people ", along with successful Olympic Games Bidding, the Chinese government will protect environment, and the regulation of restricting vehicle discharging is regular day by day.The whole world is to reducing vehicle emission pollution and improving this strategic objective of vehicle fuel economy and adopt new technologies and methods: purification techniques 1., promptly keep motor car engine fuel air system core position, as the cleaning of carburetor, fuel injector gas admittance valve with remove the sediment that these positions form, its objective is to allow fuel and air remain the good mixing state, improve burning efficiency; 2. improve engine design,, change diesel engine premixed combustion and change direct injection into, improve air and fuel mixization, improve burning efficiency as changing gasoline engine carburetor into fuel injector; 3. arrangement for catalytic purification is adopted in auto exhaust, with nuisance HC, Co, the No in the exhaust
xDeng the Co that is converted into the human body nonhazardous

2O and N
2, i.e. post-processing technology.Wherein the interior purification techniques of fuel air system is the easiest minimum with the input expense.But the interior purification of fuel air system requires to remain cleaning in operational process.Concerning petrol engine, used Fuel Petroleum contains alkene and diolefin, these potential gums, these are near more apart from the firing chamber with carburetor, fuel injector, gas admittance valve when it, the position that working temperature is high more, their high-temperature oxydations generate sedimental speed aggravation, and sediment increases.Usually the method that addresses this problem is to add fuel oil cleaning agent in gasoline.Detersive is various in style in the market, and to its cleaning and the effect of keeping a public place clean except through the conventional evaluation, also will be, and then further verify through actual road test through the Primary Evaluation and the sequence test of model engine stand of laboratory simulation test.Because the bench test cycle is long, the expense height, and a large amount of detersive and compound prescription screening can't be undertaken by them.China is studied in this regard at present, and mainly by import U.S. Southwest Research Inst. fuel nozzle deposit test instrument and gas admittance valve deposit test instrument, the consumption of not only expense height, and its accessory also will constantly rely on import.
Content of the present utility model:
The purpose of this utility model be to provide a kind of easy and simple to handle, the test materials are few, test is quick, save engine pedestal expensive expense, can arbitrarily change the sedimental laboratory of engine intake valve pick-up unit in test condition, the actual automobilism of simulation.
The purpose of this utility model can realize by following measure:
A kind of engine intake valve carbon deposit laboratory pick-up unit, on gun stand, be fixed with automatic spray gun, the gas access of automatic spray gun links to each other with wireway, links to each other with tank of compressed air with reduction valve by solenoid valve on the wireway, also is connected with the time relay on the solenoid valve; Also be connected with oil-storing cup on the automatic spray gun, be provided with deposition plate with the corresponding well heater of automatic spray gun, well heater links to each other with temperature controller by the thermometric galvanic couple.
The utility model has the following advantages compared to existing technology:
The utility model manufactures and designs according to the principle of work of automobile gasoline machine gas handling system, can simulate gas admittance valve duty in the moving row of actual automobile, therefore can utilize the utility model to fuel oil with the tendency of the gas admittance valve carbon deposit of fuel oil after the detersive under the real engine duty or the detergency of detersive.The utility model operating process is simple, and the automaticity height for engine rig test provides preliminary foundation, thereby is saved expensive engine rig test expense.

Preferred forms of the present utility model:
The utility model is also incited somebody to action in conjunction with the accompanying drawings, and embodiment is further described:
A kind of engine intake valve fouling test chamber pick-up unit, on gun stand 7, be fixed with automatic spray gun 6, automatic spray gun 6 is provided with flow regulation nut 8, the gas access 10 of automatic spray gun 6 links to each other with wireway 4, link to each other with tank of compressed air 1 with reduction valve 2 by solenoid valve 3 on the wireway 4, also be connected with the time relay 5 of two series connection on the solenoid valve 3; Also be connected with oil-storing cup 9 on the automatic spray gun 6, be provided with deposition plate 12 with automatic spray gun 6 corresponding well heaters 11, well heater 11 links to each other with temperature controller 15 by thermometric galvanic couple 14, and also is connected with heating power supply 13 on the well heater 11.
In the utility model, oil-storing cup 9 built-in screen packs to cross the residue of elimination formation testing, prevent to stop up the pipeline and the nozzle of spray gun, and in the test, solenoid valve 3 cuts out, and gas circuit is cut off, and fuel oil does not spray; Solenoid valve 3 is opened, and then air-flow ejection is sprayed fuel oil by automatic spray gun 6.The unlatching of solenoid valve 3 is realized by two time relays 5 respectively; And can regulate distributive value by testing requirements, air fuelization, injection rate and time length, can realize the various situations in the simulated automotive actual motion, under the confirmed test condition, by automatic spray gun body 6 jet-flow pneumatic nozzle atomization and air mixed, gas-oil mixture is ejected on the heated testpieces surface test fuel, tests deposition, the sediment weight of then weighing collected is with the sedimental cleansing performance of estimating gasoline cleaning agent of how much investigating.
