Auto paster benefits, to listen to the other riders say

    Auto paster benefits, to listen to the other riders say

With more and more hot weather, the temperature inside the car from 21 degrees Celsius to 27 degrees, the temperature error probability of the driver's reaction time increased 50%, down 22%, so a good car with the car air-conditioning, can effectively increase the strain capacity, prevent accidents. In addition, the film can effectively prevent accidents when the additional damage caused by glass splash, protect the car etc.. The film what in the end? Here, I discuss with you.
Auto paster what effect is there?
Energy Film Window Film 36-by-48-Inch
(1) to create the best beauty. When the owners envious of high-grade imported car glass color beauty, riot solar film can make this beauty become a reality in the owner of the car.
(2) to improve the anti explosion performance. Vehicle antiriot solar film can safe level at the time of the accident car, make the car broken glass to a minimum, the maximum to avoid damage to the passenger's accident.
(3) to improve the efficiency of the air conditioning. Vehicle antiriot film insulation rate can reach 50%-95%, effectively reduce the automobile air-conditioning use, save fuel, improve the efficiency of air conditioning.
(4) against harmful uv. Ultraviolet radiation sterilization, but on human skin also has the violation, the crew for long time, the car body, basically in a static state, the more easy to UV damage, cause skin disease. Sun film can prevent the ultraviolet ray effectively, the protection of human skin.
(5) ensure your privacy. If the owner is the importance of privacy, sun film single perspective for the owners to stop ordinary vision. Put away
How to choose the car?
Judge the film to look at their own fitness standards on membrane function where demand. If the pursuit of high definition and high anti ultraviolet properties of the preferred 3M, if the pursuit of high thermal insulation on the choice of 3M crystalline series, quantum diamonds 70 or V-KOOL's V series, but if the pursuit of high insulation and mind stop signal performance and oxidation on the election of 3M crystalline 70, if the pursuit of high privacy is the preferred 3M (unidirectional perspective effect is good) choose a good brand, more important is the choice of construction of the store, the most basic choice to ensure stronger scale authorized stores, posted the first selective membrane when had better try a few small sample comparison, have a look the color match, permeability, increased privacy requirements and other aspects Is it right? Suitable.
Automobile summer film how to choose?
Auto paster main considerations in several aspects:
1, put the sun film site must keep the environment clean, try not to use the electric fan, not on the side of the road construction.
2, the window must be absolutely clean, to do repeated washing, if the glass on the residual dust, will seriously affect the adhesion of film and the definition of the sun.
Inner 3, sun film only affixed to the glass.
The predetermined type 4, surface
Will the sun film affixed to the side window glass plane is not difficult, but attached to the surface of the windshield, high technical requirements, the general is the outer side of the front windshield as model, heat reservation on solar film.
Methods the predetermined type of the protective film solar films outward, lateral spread on the surface of glass, put water in between the sun film and glass, hair dryer with adjustable temperature to heat the solar film, while the heat while using a plastic scraper extrusion glass bubbles and water, so that the solar membrane deformation, surface until and the glass match. In need of special attention is, heat uniformly, do not over concentration, or temperature is too high may cause the glass cracking.
5, the film process
First on the inside of the clean glass spraying water, protective film and torn solar films, surface of glue also sprayed water, will the sun film is pasted on the glass, and plastic scraper extrusion, remove the solar film inner bubbles and excess water. The curved glass, such as individual parts do not agree, can also be used hair dryer heating, so that its deformation, achieve complete agreement. When the sun film after drying, can be firmly adhered to the glass.
6, because the sun film is affixed to the window side, the film before, should be in the space inside the car spraying water, makes the dust particles to sink. The film, even though the temperature inside the car is high, but also do not use the car air conditioning. Put away
Car should be how to care?
Auto paster, in seven days, please don't lift window or water wash, do not let the air conditioning outlet to the glass blowing, lest cause fall off water wet. Due to the weather and different metallic materials, film paste after drying degree will have the difference, the fast 2 days, slowly 7-15 days, in some climates, car membrane may appear mist or beads, please don't worry, is a normal phenomenon, will automatically disappear. Membrane surface stains, please do not wipe with a chemical solvent, preferably with clean wet towel, towel with water or cotton swab with detergent for cleaning. Auto paster, don't open the heating wire 10 days, open the heating wire can cause heating wire edge bubbles appear, later to repair.
Car after the need to pay attention to what?
1 just after construction of the film adhesion is very low, do not touch the film by hand, especially the mask edge.
2 just after construction of the film may produce bubbles and Alice, please return to the shop review on the second day; water marks, small blisters or fog phenomenon after the dry disappear (about 1 weeks -1 months), unclear please consult the film master or we just stick film, please more than the sun.
3 just after construction of the 7 days not window, and don't open file electrothermic demister wire, clear

Single point injection and multi-point EFI,EFI car nozzle repair experience

Single point injection and multi-point EFI
http://www.amazon.com/gp/product/B004LFCZM6/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B004LFCZM6&linkCode=as2&tag=seeworld07-20&linkId=ACUKDLD4GAFW7ZZO

Review: A, single point injection and multi-point EFI comparison: single point injection is also called the motorcycle carburetor, is controlled by computer will be a cavity in the oil is injected into the similar carburetor, (only one nozzle) and then turn into the cylinder combustion. Multi point injection is the oil injected directly into the gas cylinder combustion, one for each cylinder head. Multipoint EFI EFI technology development results, because it is sprayed directly into the cylinder combustion respectively, so the fuel ratio control is more accurate, better engine emissions, speed faster, throttle sensitive. Single point injection is the result of the carburetor to EFI technology transition, because with the carburetor work in basically the same, so don't change the original carburetor engine cylinder design, directly to the carburetor to change a set of computer control equipment. Two, EFI engine open-loop control and closed-loop control: control refers to the engine computer can process according to engine speed sensor, the tail is oxygen sensor feedback back the information, control fuel further more accurate than, so that the engine can fully burning at different speeds. Open loop control refers to the engine according to set parameters in the computer (the parameter is some theories on the curve fitting) to adjust the fuel under different speed ratio, not according to the feedback information. Therefore, if the engine changes, is not to the feedback information and timely adjustment. Closed loop control is mature results of engine of the computer, and the open loop control is only transitional technology. Economic type of car engine: the multi point injection engine closed-loop control: sail, antelope, 金夏利, Xiali 2000, Yue, Pario, polo. Single point injection: ICAS, Chery, Xiali 7101, 7101UA
 
Nozzle EFI car, if not normal to open the fuel injection, will cause the engine not working, common maintenance methods are replaced with new parts, the nozzle of the broken parts can be repaired. Some disabled long car, if difficult to start, or after starting the engine nozzle shaking, no open normally caused by this phenomenon is the individual nozzle or cold start, EFI car is old, the more this phenomenon. Then you can get a screwdriver, contact the nozzle to nozzle nozzle work, the normal work of the sound is crisp patter, frequency with the engine speed increases, the abnormal sound weaker, or simply not to hear the clatter of nozzle opening, this is because the auto oil has been used for a long time later, the internal will precipitate glial more sticky, needle valve nozzle will be glial stick, cause the needle valve side. It does not need to replace the nozzle, can remove the nozzle, the nozzle of the measured resistance, different car, different types of nozzle resistance is different, but the resistance of the same car should be basically the same, the same car nozzle resistance value of maximum error for high resistance nozzle should be in 0.8 Omega, for the low resistance injector, in 0.2 Omega within the resistance value, if qualified, we can try to repair according to the following method.
Take a bottle of carburetor cleaning agent, to find a small bottle, the carburetor cleaning agent is sprayed on the bottle, then put into the oil mouth cleaning agent inside the cap into the nozzle end, filled, the nozzle exterior for cloth, and then sealed with transparent tape upper oil inlet, to prevent the cleaning agent evaporation then, the nozzle inlet, placed on the night, second days, the nozzle mounted to the electronic test instrument can carry out repair work. Spray cleaning tester of many types, including a domestic ANLI-2000 (safety signs) machine is very good, this machine on proprietary file was used to repair the nozzle. The boot after the election to ninth gear, machine nozzle wire inserted in the nozzle, press the start button, the machine will send to the nozzle driving pulse, then can get a screwdriver with wooden handle, one end of the central tap nozzle, nozzle can be recovered action, then put the nozzle in the ultrasonic cleaning tank cleaning, cleaning after being placed on the test stand test, through the comprehensive test to determine whether the nozzle nozzle available, in addition to the conventional sealing, spray shape, flow testing, should also test the nozzle on jet engine speed variation of the responding ability and speed of all kinds, such as acceleration, jerk Deceleration Test after passing, can the loading.
