There are three main reasons for high car fuel consumption. Below is a detailed introduction to the causes of high fuel consumption and their solutions: 1. Temperature effects causing fuel consumption fluctuations: The vehicle should be cooled down promptly. You can park the car in a shaded area or use water for physical cooling. 2. Long-term lack of maintenance: Dirty engine oil and air filters can easily lead to increased fuel consumption. It is necessary to clean the engine oil and air filters promptly. Replace the air filter if necessary. 3. Aging spark plugs: Spark plugs have a certain service life. When they age, the ignition energy becomes insufficient, which can lead to delayed ignition and increased fuel consumption. Spark plugs should be replaced in a timely manner.

I've encountered high fuel consumption many times, mainly due to poor driving habits like sudden acceleration and hard braking, coupled with delayed vehicle maintenance. Issues like spark plug carbon buildup or a dirty air filter can make the engine work harder and less efficiently. The solution is to develop good driving habits, maintaining a steady speed of 60 to 80 km/h for optimal fuel economy. Regular maintenance, checking tire pressure to ensure it's at the standard value to reduce resistance, and avoiding carrying unnecessary weight in the car also help. I remember once when I skipped a minor service, my fuel consumption spiked by 30%. After cleaning the throttle body and replacing the filter, it returned to normal. This approach not only saves money but is also eco-friendly. Safety comes first on the road, and prevention is key to avoiding problems.

What are the symptoms of a faulty intercooler?

The symptoms of a faulty intercooler include: decreased vehicle power, black smoke from the exhaust, severe engine cylinder wear, and serious engine carbon buildup. The intercooler is a supporting component of turbocharging, and its function is to reduce the temperature of the high-temperature air after pressurization, thereby lowering the thermal load on the engine, increasing the intake volume, and enhancing the engine's power. The cleaning method for the intercooler is as follows: 1. Add a water solution containing about 2% soda ash at a temperature of 70-80°C into the intercooler; 2. Fill it up and wait for about 15 minutes, then shake it back and forth several times before pouring out the cleaning solution; 3. Rinse with a clean water solution containing about 2% soda ash until it is relatively clean; 4. Finally, rinse with clean hot water at a temperature of 80-90°C until clear water comes out.

What Causes Shaking When Starting an Automatic Transmission Car?

The reasons for shaking when starting an automatic transmission car are: 1. The throttle is too dirty, causing uneven air intake and operation; 2. Fuel line obstruction, leading to insufficient fuel supply at low throttle and uneven operation of engine cylinders; 3. Abnormal transmission operation; 4. Broken or burnt high-voltage wires or spark plug breakdown causing some cylinders to misfire, resulting in unstable engine operation; 5. Battery voltage is outside the specified range. The correct starting sequence for an automatic transmission car is: 1. Turn the ignition key to the power position to initiate the car's computer system self-check for about 6 seconds; 2. Press the foot brake, shift the gear from P to N, release the foot brake, then turn the ignition key to the start position to fire up the engine; 3. Press the foot brake, release the handbrake, shift from N to D gear, and slowly release the foot brake to start moving.
