The spark

The spark plugs are responsible for blowing up a bow positive coil current traveling by means of an electrode isolated by ceramic with negative mass, which goes in the body of the plug. The spark plugs differ by size, thread and thermal range, and also have the ability to cool in their workplace. It should always wear those recommended by the vehicle manufacturer or the equivalent. They are currently disappearing hundreds of different models and are getting about 4 generic types of plugs for all motor.

The spark plug is a very useful to see the operation of the engine, as colors and acquires deposits similar to those in the combustion chamber mirror. Correct reading your expert eyes can deduct the mixture, detonation, and presence of oil and proper heat range of the spark plug.

It is a key to diagnosis in all synchronization. Electrodes that can be repaired (if not especially metal) with a flat condition for the spark to jump to the edges and the distance between them are recalibrated spent. Unless it is loose or broken pottery and loses compression, spark plug has no other problems.

When dirty excess oil (engine damaged), petrol (poorly tuned) or charcoal (fruit of the previous two) electrodes are isolated and not the spark. Although a passenger remedy is not correct to claim correct engine problems such as those cited by changing the heat range of the spark plug, which must always be the one who kicks the engine workshop manual. The special metal plugs do not increase engine power as evil but pray commercials are better conductors of electricity and less susceptible to fouling, especially in the cold start. The same goes for the multiple electrodes rise but ultimately not one spark and it seeks the best point, but does not improve performance.

Excessive electrode distance can also hinder or prevent spark jumping, so many recover with calibration.

Symptoms: Damaged or dirty spark plug is seen immediately by a lack of power (the work of the affected cylinder is lost) and the noise of engine failure is very easy to learn and detect.

Lifecycle: Spark plugs last 30,000 miles easily and more. If they are calibrated, you can extend your life once done service

Condenser

In the system of platinum and condenser plays a vital role because it not only protects the breaker sparks generated when making the circuit, but creates an increased tension in the primary circuit of the coil, so its capacity must agree with this.

Symptoms: When the engine has a fault it is impossible to immediately detect failure as low, in stockings, sometimes high, match and fails again, is surely the condenser and not has to change different arrangement.

Lifecycle: You can outlast the car and your damages are rare, perhaps because they change each synchronization unnecessarily because it’s like a light bulb: one replaces it if it melts when damaged. It is recommended, when it serviced the engine, keep the condenser surely going to change (and if you walked the engine is sure it works) 

Coil

The coil is responsible for generating the high voltage going to the spark plug and initiate combustion of the mixture when the spark jumps between two electrodes. Your inner work generates much heat, which is usually cooled by oil and is sealed. Do not believe the manual mechanical diagnosis usually predicts their status to the touch, because all are heated. Failures are damaging internal circuits or breaking the insulation where it exits the current.

Many are interchangeable, but in recent engines are usually specific for placement, connectors and compatibility with the computer or electronic module.

The test is simple, because if there is no spark no power, damaged. Do not confuse the coil current and should reach the spark plug, because it can be interrupted at the way the wires, distributor cap or brush.

Symptoms: the ignition and the engine is cut off.

Lifecycle: Unlimited but unpredictable, like any electrical appliance, and the only remedy is change. They have to be sealed under.

High Voltage Cables

Carbureted or injected, all engines are driving the high voltage between coils that produce and spark plugs. Lately they have come out with systems? Rolled into one? And the coil is directly over the spark plug without distributor as orders spark gives directly the computer, as the advance.

The cables are getting better and conductivity, so the replacement is not as frequent. But anyway generators are failures. Put thicker cables means no improvement in spark ignition or if the car has are adequate.

Symtoms: There are two problems. When the signal is cut, it may be due to rupture of the terminals, no current source (coil, or stops at the top). And if there is excessive resistance, haggling occurs when the engine goes under load, for example, accelerates to climb a bridge or spend a corner and the engine seems no power. Sometimes the wires are burned from hot parts as and when they approach exosto there is a spark jump out of the spark plug and the engine fails.

Lifecycle: It varies depending on the quality of the items. Must be replaced if there are no faults, then a measurement of the resistance to current flow, the corresponding apparatus. Do not change just because.

Injectors

The injectors of injection systems are highly protected. There are filters on the suction point in the tank, line and again at the entrance of the injector, so it’s not often get clogged. It happens with gasoline gum will sometimes blocking and flow is uneven, so the engine loses power or fails.

When the electric mechanism is damaged, the injector can be locked open and floods the motor (with danger of a hydraulic shock) or simply does not add fuel. This damage can be in the injector itself, the computer commands or line electrical signal.

 

It is advisable to bathe and clean with ultrasound every 50 thousand miles, but cautions problems that are equivalent to those of a dirt in the carburetor. The online liquid cleaners are not recommended because, somehow or another formula, contain detergents that will finally cylinders and dilute the oil. Or just move the dirt site.

 

Do not change them without going through the special machine to test as many mechanics choose to order new and very expensive, when they can be good or repairable.

Symptoms: If the engine works at least one cylinder and the spark plug is not, it’s probably the inoperative injector. Low power, intermittent, black exhaust smoke or very white tube may indicate miscalibraction thereof.

Lifecycle: Undefined, can go years without disturbing like entering Unfortunately anytime. Watching them every 50 thousand is correct.

Filters

The filters are of three types and all are part of routine maintenance. The most critical of all, in the sense that usually does not cause serious flaws but it induces a large engine wear is the air. If you are covered, hard little air and the mixture is very rich in gasoline, resulting in immediate dilution of the oil drop and lubricity. If no controls dust, motor quickly just because the land is sand in the cylinders.

The oil filter should be changed when the lubricant is replaced and is recommended between 8 and 10 thousand miles with conventional oil high specification.
Fuel filters are part of the synchronization process when the engine is carbureted and have a review cycle of about 40 thousand kilometers in the injected. In this case, as the filter is sealed, the weight of the unit is indicative of the amount of dirt that may be in and if you have much restriction immediately generates excessive strain on the electric pump until burning.

 

Symptoms: As every problem of gasoline, failures are jostling for intermittent fuel delivery and injection increased operating noise of the pump that will placed in the back near the tank or immersed in the perceived same.

Lifecycle: The values ​​quoted in the footnote, unless some specific failure.
