The air flow meter is broken. What's wrong with the engine?

Abnormal airflow voltage range, too high airflow voltage, too low airflow voltage, too thin mixture and too thick mixture will all lead to idling jitter, starting flameout, weak acceleration, increased fuel consumption and black smoke from the exhaust pipe.

Users can judge by measuring the output voltage data when the engine is running that the standard voltage of the engine is 0.8- 1.4V when idling, and the voltage signal can be close to 4V when accelerating to full load. If it is not within this range, it may be that the air flow sensor itself is damaged, or it may be caused by dirty things. Just clean it.

Precautions:

1, the installation location of the equipment should be selected in a place convenient for inspection, maintenance and disassembly, with good ventilation and easy installation and disassembly. Corrosive, vibration does not affect pedestrians and neighbors.

2. The women's seat of the equipment should be selected in the place where the overhaul, maintenance and disassembly I are well ventilated and have only a slight impact on the installation and disassembly of pedestrians and adjacent equipment.

3. The installation of the installation should be firm, neat and beautiful, and the signs such as equipment number, terminal number, use sign and operation sign should be intact and written correctly and clearly.

4. It is not suitable to install the equipment in places with high temperature, humidity, dust, explosion or fire danger, which will interfere with nearby instruments. When it is inevitable, corresponding protective measures should be taken.

5. When checking, cleaning or installing the equipment, the air flowmeter should not damage the insulation, internal wiring and contact parts of the equipment. When there is no special reason, the sealed adjustable device and cover of the equipment shall not be unsealed, and shall be resealed after unsealing, and records shall be made.
