Car fuel consumption has always been a matter of concern to everyone. Many car owners will encounter such a situation: the more the car drives, the more familiar it is, but the fuel consumption is getting higher and higher! What's going on?
The soaring fuel consumption may be caused by this part-spark plug!
What is the relationship between spark plug and fuel consumption?
Spark plug is the main component that ignites the oil-gas mixture in the cylinder (diesel engines do not need spark plug ignition). If the engine is the heart of the car, then the spark plug is the "pacemaker" of the heart of the engine. Its poor performance or aging will inevitably lead to engine fatigue and increased fuel consumption.
If the combustion of the mixture in the cylinder is sufficient, the spark plug plays a great role and also has a great influence on the fuel consumption. If some spark plugs do not work, fuel consumption will increase significantly.
For example, for a car with four cylinder engines, if the spark plug working condition on one cylinder is not good or does not work, the fuel consumption will increase by more than 30%.
Some driver friends like to use ordinary spark plugs as long service life spark plugs. They think that the longer they take, the better the spark plugs will be. In fact, they will sacrifice high energy consumption.
The working environment of spark plug is very harsh. In the cylinder of the engine, it is ablated by high temperature and high pressure gas for a long time. In addition, due to the loss of electrode itself, its performance will continue to decline, especially its insulator porcelain items, the insulation decreased significantly, resulting in the breakdown of the high voltage of the mixture, from the insulator porcelain items "copy the shortcut", resulting in electricity leakage.
Suggestion: replace the spark plug frequently and keep the spark plug in good working condition all the time.
How do I check if the spark plug needs to be replaced?
1. Replace the spark plug according to its service life. Currently, the commonly used spark plugs are divided into resistance spark plugs, Platinum spark plugs and Iridium spark plugs. Generally speaking, the life of resistance spark plug is 20000 kilometers, the life of Platinum spark plug is 40000 kilometers, while the life of Iridium spark plug can reach 6 to 80000 kilometers.
2. Remove the spark plug and check it to see if the color of burning, the gap of electrode, the gap between porcelain body and metal shell leaks air, etc.
In addition to spark plugs, pay attention to these parts:
1. Throttle gate, always check the pollution situation and clean it timely to prevent carbon deposit or dust;
2. Sensors, especially those related to oil supply, gas supply, temperature, rotating speed, etc., ensure that the computer can obtain correct fuel supply information and always maintain timing and sufficient supply of economical and efficient fuel;
3. High voltage wire and ignition coil to ensure that the insulation does not age and always provide sufficient breakdown voltage for spark plugs;
4. Regular inspection and maintenance hit iron wire. In fact, 70% of the car's faults are caused by poor contact with iron wire. Due to poor iron wire, it will also cause poor ignition of spark plugs or poor operation of the fuel supply system of automobiles, resulting in poor ignition and inadequate ignition during ignition, repeated supply when fuel is supplied or should not be supplied, etc, causing waste of fuel;
5. Fuel electronic pump, ensure that it always has enough pump oil pressure;
6. The gas supply components of dual fuel vehicles must always be in good working conditions.
In a word, the components related to ensuring that the fuel can sufficient burning in the cylinder of the engine need regular or regular maintenance, so as to ensure that the fuel consumption of the engine is normal, economical and not wasted.
