can give the driver a sense of accelerated posted back turbocharger has become mainstream, but many owners still have equal Turbo concept of “Trouble” is.
Indeed turbo cars because of increased peripheral part relationships, maintenance is certainly more complicated things, but the owners do not just have to get off delay flameout, with regular oil changes two concepts, but also be able to understand engines, turbines associated with peripheral configuration, when the problem occurred where to go to check, or what kind of potential crisis this sign will appear. As long as they have a preliminary understanding, contacts turbine will not difficult, really enjoy the height of the turbine car fun to drive.
turbo car first heavy oil supply / ignition status most important
is a turbo car ignition and fuel supply situation, the most able to show the status of the spark plug engine, you must always check, because the combustion turbine engine, if unusual, immediately will allow the engine to malfunction.
Usually a turbine in order to protect the vehicle engine, when tuning and oil are more richer value cold spark plug, the spark plug will therefore when viewing slightly moist and slightly dark, the spark plug inspection of the turbine engine, the first is Note whether the center electrode of the spark gap is too large, and whether the electrodes to melt phenomenon, if there is likely to be on behalf of the spontaneous combustion of mixed gas, oil into the combustion chamber of the abnormal phenomenon of the explosion, to hurry to check whether the oil tuning problems .
and the ceramic portion of the center electrode and with a pressurized oil supply and its value in the event of cracks also represents a very serious engine knocking, the ignition timing must go. Further As presentation while viewing the spark plug electrode over white, if the upper end of the ceramic charred, theoretically the number of the spark plug is coupled with lack of oil caused by low numbers, if the alloy particles reattach the tip, then the spark plug had completely meltdown these metal particles already inside the cylinder as the actuator in damage to the engine, can only be disassembled overhaul!
car driving turbine supplies must be used as a spark plug, it is recommended every 2-40000 kilometers that is updated on a turbo car due to a spark plug in high-pressure compression state moving testimony, the spark plug electrode wearVery large, life will be relatively short, the job must be replaced from time to time. It is noteworthy that today’s popular iridium spark plug electrodes are very thin, with a high ignition efficiency reasons, often still can ignition electrodes are gone, but you must not continue to retain, the job must be replaced as soon as possible.
Collection FAQ turbine
will be the case throughout the turbine engine operating failure occurs, mostly air leakage intake process, the electronic control components errors, as well Turbine failure caused, in addition to these problems are indeed affect the whole body except, sometimes even cause engine damage overall, to completely avoid these faults out, keep in mind the following conditions.
One problem: a sudden increase in speed can not be
If you experience such problems should first check flow meter (Flow Meter) or pressure Sensor (MAP Sensor) whether the fault, if fault happens to the dashboard also lit the lamp can be more certain issues both happened. Cause
flowmeter malfunction, mostly to increase the engine turbine, the air volume which exceeds the range of voltage values can be otherwise measured, resulting in burning of the lead meter, through no longer is the air filter when no dress or poorly fixed by the dust collection effect or wet filter element, so that the core wire inside the meter is broken by vibration and oil stains and dust damage.
so carefully choose the installation of air core and indeed it is a very important thing, especially in sensitive flowmeter Japanese vehicles, but also to pay attention to its fragile hotline core, clean-up when using high-pressure air gun must not be, but naturally dried after spraying of cleaning agent.
Further turbine type flowmeter can best car modified Blow-off, pressurized air does not backflushed to prevent back flow meter rapid resumption of oil and damage.
Second problem: abnormal sudden drop boost value
When this issue, the intake line first thought possible leakage, which often occurs in the charge transfer value after high (Boost-up) or modified pre intercooler. If it is found emit exhaust blackSmoke, the more can be determined entrance side of the pipeline into the intercooler depilated or squib, a strong need to use sub-beams on the folder, high density silicone tube (Silicon) is indeed locked; relief valve stuck in addition, wear and spring pounds is not enough, they will form a leak must be checked at any time to clean up, to ensure safety.
again when you have the problem of excessive pressurization problems may be the boost control solenoid valve, which is connected with a suction pipe without cracks stability, hence the situation of excessive Boost produced; reverse If the damage is a continuation of the positive pressure tube, the pressure will raise it up. In general electronic controller into the solenoid valve, are attached to the cartridge access end, i.e. object is to prevent clogging of the valve, if a failure as early as possible in this area processing, due to the unstable Boost and very easy to damage to the turbine engine.
three problems: exact unpressurized
If it is found, then no pressurized, one can easily determine the fault source, is inside turbine diaphragm for a long time continuous operation of driving high supercharging intake or broken due to debris, the debris will impact the metal audible through the exhaust pipe while rotating.
General omen before a failure occurs turbine will be that it will issue a percussion sound (sound design will be great unless it is some of the mechanical structure of the ceramic blade) or there is oil leakage into the trachea Road initiator exhaust white smoke, the blade bearing is already loosened, resulting in oil leakage, the exhaust gas loss of airtightness scurry like. Once inside the turbine bearing balance destroyed, unless they are shaking bring different sound with the seal to leak outside, cracked blades during actuation there will “call out” of wind noise, if not repaired as soon as possible, get a new word , engine oil stocks are likely to lack a high likelihood of injury to the internal structure of the engine.
of the turbine will generate a fault condition, the main factors to boost value to improve excessive overspeed (Over boost), cause leaf discoloration, loss of the final curved guide angle to injury bearings, so to boost the value of the lift raised the horsepower output, air filter, intake line needs to find ways to reduce the internal resistance (such as the use of air-core straight-through or an increase in diameter), or can be involved regardless of turbine inlet how much wind or no filling to achieve optimal efficiencyIt should be, and the great burden of instant acceleration. Particularly in third gear, or fifth gear full pressurization in the case of the instant acceleration heavy loads, such as not coherent suction, the negative pressure within the tube becomes large, and thus the bearing lubrication oil sucked out, the lack of lubricity.
Therefore, when making modified high boost setting, set to dress a large diameter intake pipe, a result of addition to the protection and easier to play a preferred high speed performance, but when the catheter is too large , there will be less than the low-speed torque and boost slow phenomenon, how to strike a balance in both, that’s a test of skill construction.
Question 4: Length instability car idling turbine
Many owners prefer turbine air bleeder Blow-off sound , but the problem often encountered is a dress up, it will make the idle is low, turn off the oil back into the case, which was due Blow-off valve is too soft so that pressurized air is released too much, resulting in a flow meter has been passed the flow rate signal and the actual engine intake computers vary, the result is partial concentration of oil and gas resulting in low speed or even turn off.
To solve this problem there are two methods, one is replaced original lead the way back into circulation after the meter, it will not affect the supply of computers calculating, as another modification Map sensor (Sensor manifold pressure), the oil supply supplemented by a computer to tune. Putting the relief valve when the valve is too soft, the whole supercharging leak situation occurs, can not achieve the expected boost value, the weight must be adjusted charge energizing spring (the upper end of the adjustment screw is attached), such as when not resolved, you need to dress up a higher number of pounds of spring.
Also as long as the engine, too dirty and blocked at the intake of the air cleaner case, the intake resistance can cause large idle could be reduced, although there is now a computer idling motor speed automatic do the movements, but because of active and passive cut into each other, the idle will have peaks and valleys of imbalances.
excessively dirty air filter, the performance of the overall performance of horsepower will be discounted, so must be regularly cleaning and maintenance. And the air flow meter case arranged turbine car, which is a continuation of the mounting position in the rear of the cartridge, because if the frontParts of excessive lead contamination caused the meter to detect the wrong words, ECU error message will be passed, thereby affecting the proper fuel adjustment corresponds to engine idle speed instability and even weakness will appear.
As mentioned above, however, the flow meter is best not to just clean up, because hotline in the heart of its very fragile, or handed over to construction professionals to more appropriate. Probability
Because of the multitude of the vehicle again the turbine conduit reason, idle instability occurs to the vehicle than the self-priming, when the situation is slightly leak, the negative pressure is low and will idle, and at full throttle state under pressure and can not reach the normal signs of smoke emissions, you can quickly noticed unusual form, so dress good quality and temperature, pressure of the vacuum tube Silicon is very important.
Finally, after the re-checked as above problems still idle instability situation, it must be the idle speed control or idling motor may have serious coke screws, need to open completely clean up; in addition, one nozzle may also be a problem, because it is not the moment, it will be ups and downs when it is idle or malfunction or discharge flow rate.
In addition to checking the computer back to the original insertion addition, there is a simple method for detecting, using a screwdriver to touch each cylinder injector actuating listen to see if, since a nozzle is not That will not be stable idling fuel injection, fuel injection is not on the problem-solving, is very simple to check whether the plug is loose or fall off, not what it should be fixed right, it can only be replaced at no.
See here, I think we should be due to substantial mechanical principles turbo car understanding of their repair and maintenance also have in-depth understanding, but I know most of my friends may still do not understand, so open turbine car, or find a familiar maintenance shops do it.
