The compression ratio of LeFeng 1.4L engine is 10.2:1. You can keep the shift speed at around 2500-2800 rpm except for 1st gear, because if the speed is too low, the motor will feel insufficient power. at engine speed. Low speed means the load is too large, which will damage the motor and easily form carbon deposits.
How to charge the LeFeng RV battery
The oxygen sensor is damaged, replace the oxygen sensor.
The engine oxygen sensor is damaged. If the on-board computer fails to obtain the value, the amount of fuel injection into the engine will be abnormal, resulting in high and slow engine speed. after replacing the generator at 09 Lefeng, 80 miles at 3000 rpm. The oxygen sensor can be replaced.
The way to maintain the oxygen sensor is not to use mau gasolinegood quality. Poor quality gasoline contains a lot of heavy metals, which can easily cause poisoning and oxygen sensor failure after use.
How to charge the LeFeng RV battery? You can use a portable charger to charge the battery. Open the ventilation cover. The red clamp of the charger clamps the positive pole of the battery with the plus sign and the black clamp. Fix the negative pole of the battery with minus sign, then plug it in to charge. Generally, there is a generator in the car, which can produce electricity as long as the engine runs normally. Only the generator will charge the battery. When the battery is fully charged, it will stop charging. As long as the battery is not consumed, there is no need to recharge it. The generator charges without interruption or prescribed duration. The generator changes the charging current depending on the battery level.Each time the engine starts, the power consumed is enough to charge the generator for ten to twenty minutes. The power generated by the generator must first power all electrical equipment needed to operate the engine, and the remaining power can only be charged into the battery. . If you turn on the lights when driving at night, the charging time will be longer and the power consumption will be greater, so the car battery generally does not need additional charging unless the charging system or battery has failed. When the generator is not producing electricity while driving, it can operate normally as long as the battery has power. However, if the battery is not recharged, it will drain. Once the battery is discharged, the car can no longer be driven. Car battery charging principle: The car battery and generator are connected in parallel. As long as the engine is running, the engine charges the battery and powers other devices. When the engine is not running, energy is supplied by the battery. If high current is required, the generator and battery will provide power together. The generator does not charge the battery continuously and stably.
