When the spark plugs have carbon deposits or are used for too long, it is easy to affect the ignition performance, causing incomplete fuel combustion and increasing fuel consumption. There will also be some problems, such as weak acceleration and exhaust pollution. At this time, the spark plugs should be replaced in time.
If the gap between the spark plugs is too large or too small, fuel consumption will basically increase. If the gap is too large and the ignition is not good, it is easy to cause insufficient fuel combustion, thereby affecting fuel consumption. However, if the spark plug gap is too small, the arc capacity will increase. However, due to the obvious fire extinguishing effect, the mixed gas is insufficiently burned and fuel consumption increases.
The calorific value of the spark plug will also affect fuel consumption. The heat generation is too large, the heat dissipation is faster, and the spark plug temperature is lower, which is easy to cause carbon deposits and fuel consumption. In addition, the ignition intensity of the spark plug may also affect fuel consumption, so the ignition intensity decreases and the fuel consumption naturally increases.
Therefore, factors such as spark plug gap, calorific value, and ignition intensity will affect fuel consumption. Of course, pay attention to the gap and calorific value of the spark plug when replacing the spark plug. Replacing the appropriate spark plug can increase power and save fuel.
Spark plugs, commonly known as spark plugs. The function of the spark plug is to discharge the pulsed high voltage electricity sent by the high-voltage wire (spark plug wire), break through the air between the two electrodes of the spark plug, and generate electric sparks to ignite the mixed gas in the cylinder.
The main types are: quasi-type spark plugs, edge-protruding spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, surface-jumping spark plugs, etc. The spark plug cooperates with the ignition system and the fuel supply system to make the engine work, and largely determines the performance of the engine.
The electric plate of the spark plug ignites the mixture in the cylinder through repeated and continuous power generation. At this time, other parts of the ignition system generate timely high-voltage electric pulses, forming sparks and explosions to provide the energy required for the engine power output.
The structure of the spark plug is made of a thin metal plate passing through a ceramic material with insulating function. There is a metal shell around the lower part of the insulator, which is screwed on the cylinder head in a screw thread manner. An electrode is welded at the bottom of the metal shell to form a grounding effect with the car body. In addition, at the end of the center of this electrode, it must be separated by a tiny discharge gap.
Then, the high-voltage current from the distributor will pass through this central electrode for conduction, and then discharge in the discharge gap at the bottom. At this time, the spark plug will play a role in generating sparks to burn the mixture, and the engine will get energy and output power.
It can be seen that the spark plug is a device that ignites the gasoline and air mixture entering the engine for combustion. It works under harsh conditions of high temperature and high pressure. It is one of the vulnerable parts of the gasoline engine. It plays a very important role in the operation of the engine. It has a lot to do with whether the car is fuel-efficient and whether it runs smoothly.
What other factors are related to fuel consumption?
Fuel consumption is closely related to the displacement and appearance of the car. For example, SUV cars generally consume more fuel than ordinary cars, and 1.5 displacement cars generally consume more fuel than 1.0 displacement cars. The greater the wind resistance of the car, the higher the fuel consumption.
Fuel consumption is also closely related to the external environment. If the road conditions are not very good, the car needs to constantly step on the accelerator and brake, which will also increase fuel consumption.
Car fuel consumption is also closely related to car maintenance, such as low tire pressure or oil stains on the engine surface, carbon deposits in the gearbox, etc., which will increase fuel consumption.
If the vehicle is overloaded and has irregular driving habits, such as frequent braking, slamming on the brakes, slamming on the accelerator, etc., it is easy to increase fuel consumption.
