Our company once did such an experiment: using a van, after starting the car, turn on the air conditioner, and close the doors and garage doors.
After 20 minutes, turn off the car’s engine. The measured carbon monoxide concentration in the air in the garage is 800-900mg/m3, and the hydrocarbon concentration is 9000-10000mg/m3, which are 66.7 times and 34.7 times higher than the national standard respectively; the carbon monoxide concentration in the car is 1800-2000mg/m3, and the hydrocarbon concentration The concentration is 10000-10400mg/m3. Half an hour after leaving the garage door fully open, neither carbon monoxide nor hydrocarbons were detected in the center of the garage.
Therefore, it can be seen from the above experiments that if the car is completely closed, the car is vulnerable to carbon monoxide damage. It is necessary to install a carbon monoxide sensor for car. In this way, the carbon monoxide sensor for car is installed, and we can avoid the harm caused by carbon monoxide in time.
