1. What are the types of mass flow meters?
2. Air sensor malfunction!!! The air flow sensor is one of the important sensors in electronic fuel injection engines. It is installed between the air filter and the intake hose to detect the intake volume of the engine cylinder and adjust the fuel distribution based on it. Once the air flow sensor malfunctions, it will affect the performance of the engine. Damaged air flow meters are often caused by long-term non replacement of air filters or the use of inferior air filters, resulting in the accumulation of dust inside the air flow meter, which affects its detection accuracy and lifespan. There are five common faults with air flow sensors, including abnormal air flow voltage range, high air flow voltage, low air flow voltage, lean and rich mixture. These faults can cause the car to experience idle shaking, start and stop, weak acceleration, increased fuel consumption, and black smoke from the exhaust pipe. It can be determined by measuring the output voltage data of the engine during operation: the dynamic signal voltage at the signal end of the beam containing the car plug signal. When the engine is idling, the standard voltage is 0.8-1.4V; when accelerating to full load, the voltage signal can approach 4V. If it is not within this range, it may be due to damage to the air flow sensor itself or dirt, and cleaning is sufficient. It can be judged by measuring the output voltage of the sensor: using a multimeter to detect, the general voltage value is 5V. Use a hair dryer to blow air into the sensor. If the voltage changes with the size of the incoming air volume, it is normal; If there is no change or small variation, it indicates that the flowmeter is faulty and nee
3. What is the difference between the Aivka F7 detector and the F6?
The Aivka F6-d is mainly a car fault detector. Cannot detect LNG trucks. Here are a few common questions about LNG trucks, hoping to be helpful to you.
1. How many liters of diesel is equivalent to one cubic meter of natural gas? How to convert natural gas and diesel? This is a question that users are more concerned about. LNG saves money, but how much can be saved? The answer may be found from the conversion value. 1 cubic meter of natural gas has a calorific value equal to 0.86 liters of diesel; The power generated by natural gas is equivalent to 0.75-0.8 liters of diesel.
2. In some places, LNG refueling stations are measured in kilograms, while in other places, they are measured in cubic meters. Which is more reasonable? The measurement in kilograms and cubic meters is essentially the same, except that the measurement unit is different. It should be determined according to local customs, and the measurement unit in different regions should be determined based on comprehensive analysis of customer and market conditions. The sales price can be adjusted based on changes in gasification rate using cubic meters as the unit of measurement, while kilograms are a more common unit of m
