Assembly production

1, through the automatic powder machine, the amount of resistance powder (with Bosch the same supplier) + center electrode + screw + expansion powder into the finished ceramic insulator inside, after heating, the internal structure of the spark plug has been formed.

2, after forming the need for internal voltage test, after 25000V high voltage on each of the detection of whether the breakdown of insulation and leakage, excluding unqualified products.

3, through the hot-pressing assembly line, the insulator and iron shell welding. And we are using hot riveting welding technology, this technology is currently Bosch's spark plug is also being used. Because the welding is the need for heating, so in the hexagonal screw will be under a circle of light blue halo. The NGK is the use of cold riveting technology, so the insulator and iron shell where there will be a small layer of pale white powder.

4, after assembly into the finished product, will be simulated air pressure detection, simulation of the engine cylinder operating pressure, the finished product installed into the test center electrode and the distance between the side of the electrode to achieve the ignition requirements of the engine to detect its performance and quality.

5, the detection of quality problems of finished products, for packaging.

Maintenance analysis

1, the normal working conditions: the top of the insulator was light brown, no fuel or oil deposits.

2, carbon deposition: the surface of the black sediment, indicating that the mixed gas is too thick, weak ignition or calorific value is too low. So it is recommended to check the fuel and ignition system of the engine before replacing it.

3, the electrode burned: the calorific value is not correct, or the mixture is too thin or too early ignition time, waste recycling system and the ignition line of mutual inductance may lead to early ignition.

4, the engine jitter analysis: * Idle jitter 1, intake manifold or more valve leakage; 2, throttle and inlet fouling too much; 3, idling control element failure; 4, nozzle clogging or sealing bad ; 5, ignition coil high-voltage line aging failure; 6, spark plug leakage, coke, the gap is too large. 3, the transmission shaft bending deformation; 4, oil blockage, poor oil; 5, the valve damage, cylinder pressure uneven. 2, the tire pressure is not balanced; 3, 4, the ignition coil energy is insufficient; 5, the spark plug is attached to the oil dirt, gap fire, and the fire is not enough, * Occasional flameout 1, poor fuel supply, fuel injector or oil block; 2, the sensor failure; 3, motor failure.

Engine knocking phenomenon

Engine knock is an engine abnormal combustion (overheating combustion) phenomenon, knock is usually very serious, if it is in high-speed high-load continuous and serious knock, not a minute, Spark plug and piston melting, serious even the cylinder and the engine body will be blown wear. There are six reasons: Ignition time premature - Ignition is too early, means that the piston before the deadline to establish the pressure, will hinder the piston rise, lack of power, because the piston to overcome the resistance to reach and cross the top deadline. It is possible in the intake valve is not completely closed when the combustion gas poured into the intake pipe burning, called temper, but also very scary. So to adjust the ignition time. The engine there is a serious carbon deposition - fuel or oil quality is not good, so that burning is not good, resulting in excessive carbon deposition, so to clean up the engine in time. Air-fuel ratio (A / F) is too low - air-fuel ratio, which represents the mixing ratio of air and fuel. Air-fuel ratio is an important parameter when the engine is running, it has a great impact on the exhaust emissions, the engine's power and economy, and this should check the oxygen sensor first. Cooling and cooling system work poor - cooling water due to leakage, infiltration or evaporation and reduce the natural heat away from the body will be reduced, so that the engine accumulated heat too much. The same heat sink device will make the engine heat load is too large, but also make the engine knock, timely inspection of cooling water, heat sink. Turbocharged vehicle turbines are pressurized high - turbocharged in general will allow the temperature of the front cabin to be higher and adjust the turbine pressure control device. Do not tighten the spark plug - according to the torque requirements to install the spark plug, if the spark plug did not tighten, will leak combustion gas, loss of power at the same time will lead to early ignition, causing knocking phenomenon. When this happens, remove the spark plug and observe the gasket. To determine whether our spark plug tightened, it depends on whether the sealing gasket pressure down
