Ruifeng 2.4 gasoline car has just been overhauled, and its fuel consumption is too high. No.9 only used 300 yuan gasoline to run168km. What is the reason why the gasoline is running out?

Friends read your narrative; Your fuel consumption after the overhaul of Ruifeng 2.4 is really high, which is also related to the overhaul of the engine, but other parts will also cause excessive fuel consumption of the engine. Please check and eliminate several components that lead to increased fuel consumption; 1, the nozzle is not tightly sealed, and the fuel injection from the nozzle is uneven, which will increase the fuel consumption. Check and clean the fuel nozzle. 2. Dirty or bad oil pressure regulator leads to high oil pressure, and the normal idle injection pressure is 2.5-3 Pa. If it is high, the fuel consumption will increase. 3. Whether the spark plug of the ignition system has high pressure and weak fire will cause the power point to fail to keep up and the fuel consumption will increase a lot. 4. Check whether the relevant sensors work normally, including water temperature sensor, air flow meter, throttle position sensor, intake pressure sensor, etc. Then, check whether the air filter is seriously blocked. If there is congestion, it will lead to too little intake air and too rich mixture, which will lead to an increase in fuel consumption. Combined with my analysis, I went to the repair shop for on-the-spot judgment and inspection. I wish you an early troubleshooting of high fuel consumption.
