• How to replace spark plugs

    Every gasoline engine has spark plugs, a cylinder has one, and individual high - speed g gasoline engine have two spark plugs per cylinder. The spark plug is only a small part, but it is so important parts in the ignition system. Spark plugs are consumables, yet most drivers pay little attention to such a common part. As the core of a car engine, the performance of spark plugs can almost directly determine the car’s performance, so we recommend you often check your car's spark plugs. How to judge the spark plug life Spark plug is an essential part of the normal operation of the engine. After the mixture is sucked into the cylinder and compressed, it must be ignited by the spark plug to complete the work. Therefore, to a certain extent, the performance of the spark plug will directly affect the ignition explosion of the mixture. However, the spark plug electrode will also be consumed during the ignition process. Depending on the melting point, hardness and other factors of the electrode material, the electrode will be gradually consumed. When the electrode gap is too large, the vehicle will appear power decline, hard cold start, increase in fuel consumption and other problems, then it is best to consider the replacement of spark plug. Generally speaking, the normal service life of the spark plug of the family car is about 20,000 kilometers. In addition, to extend the durability of spark plugs, some manufacturers use precious metals such as platinum and iridium in the electrodes, as well as the strength of the ignition energy.

  • How to remove the carbon deposit

    Speaking of car with electronic fuel injection, maybe a layman can tell one or two of its advantages, such as energy saving, environmental protection and so on. With the popularization of electronic fuel injection, some of its special faults also follow, the most typical is the symptom of carbon deposit. Carbon deposit can generate in valve, combustion chamber and intake pipe 1. Carbon deposit in valves and combustion chamber The characteristics of the engine with electronic fuel injection determine the ignition, injects the air- fuel mixture, then ignites. When we turn off the engine, the ignition is cut off immediately, but the working cycle has done, the useless fuel will exist. Due to volatilization of gasoline, some substance (wax and gel)will stay on inlet valve and combustion chamber wall and harden after repeated heating, carbon deposit has generated over time. If the engine burns oil, or the gasoline is filled with low quality impurities, the valve will accumulate more carbon and form more quickly.

  • Driving habits cause carbon sludge buildup on your engine

    Most of us encountered such a problem in the driving process, the car engine shakes while idling, and idling speed up to 950 RPM. We got into the panic. Generally, it is not a big issue, we just need to figure out what causes lead to this symptom. In fact, there are several reasons for this symptom, roughly divided into three main reasons: engine misfire, excessive carbon deposition of throttle, excessive pressure fluctuation of fuel system.

  • What is a distributor

    Distributor is a part of the ignition system, which can control the switch of the primary circuit and distribute the spark to the spark plug of each cylinder in order. The distributor is mainly used in the conventional ignition system and the common electronic ignition system, but these two ignition systems have been basically eliminated. Now the automobile engine eliminate the distributor. Working principle of distributor In the battery ignition system, the distributor and the breaker are usually on the same shaft and driven by the valve camshaft. It also has ignition advance angle adjustment device and capacitor, etc. Breaker arm in distributor closes the contact with a spring leaf and opens the contact with breaker cam. The opening clearance is about 0.30~0.45 mm. The number of bulge in breaker cam is the same as the number of cylinders.

  • Toyota Corolla fault diagnosis and maintenance of ignition system

    Toyota Corolla fault diagnosis and maintenance of ignition system . The ignition system is a key component for car , which is also the source of many faults. If we want to troubleshoot problems, we must be in-depth analysis and to explore the ignition system fault diagnosis and maintenance. Taking Toyota Corolla ignition system as the analysis object, explore its fault diagnosis and maintenance , hope to help maintenance technicians to repair ignition system problems. Ignition system with distributor In the conventional ignition system, the current flows into the coil and be intensified field, routed through the distributor via contact with rotor on the distributor. The distributor is driven by the engine’s camshaft. As it rotates, the cam pushed the points open and close. Each time the points open, the flow of current is interrupted through the coil, collapsing the magnetic field and producing a high voltage surge through the secondary winding. Toyota Corolla use the electronic ignition system, which use semiconductor component to produce pulse signal to ignite. The current of ignition coil can be switched on and off directly, at the same time, the high voltage current in secondary circuit was distributed to the spark plug through the distributor and jump spark. If accompanied with failure, its diagnosis and repair need to pay attention.

  • Ignition system upgrade

    We'll start with the ignition system for gasoline cars, and logically break the content of ignition system down into easy to read chunks. With the development of automobile technology, the ignition system is basically divided into traditional ignition system and electronic ignition system. In fact, these two ignition system are still used in automobiles. The two ignition system work on roughly the same principle and operate in the same circuit. The only difference is whether the type of ignition is mechanical or computerized.

  • Why my check engine light on

    Check engine light different from other warning light on the dashboard such as oil level light, water temperature light. If check engine light is on, the problem is much more complex. Check engine light is also a common problem, If check engine light comes on suddenly while driving, can I continue to drive? This is a very difficult question, because check engine light, the problem can be severe or mild. Even no problem also can be detected "false failure", and another phenomenon is that check engine light occasionally is on or off. In fact, this false failure is also very easy to understand, indicates the fuel is not up to fuel standard, or the oil is poor quality. Other problems (such as carbon deposition) caused by insufficient mixture combustion can illuminate engine warning light. Fuse and some of the sensor circuit is poor contact by vibration when a car is running, which also lead to check engine light on occasionally.

  • Faults and symptoms of ignition coil

    The common faults of ignition coil are: Damaged by external forces and burnt due to excessive current. If the ignition coil is damaged, the ignition system will not work and the engine will not be able to start. Another fault is inevitable, which is caused by the aging of ignition coil. The ignition coil fails in several situations 1. An individual cylinder does not work without spark, lead to shake at idle and poor acceleration when refueling. 2. The electrical leakage of ignition coil, idling engine wobble sometimes have or sometimes not, but poor acceleration when refueling 3. When accelerating,sometimes resulting in engine wobble because the electricity supply has been cut off. 4. If the ignition coil has a fault, the car doesn’t start.
