It is supposed to sense smoke.
The smoke detectors use the photoelectric effect or a sensor based on the ionization differences between smoke and air.
Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
A photoelectric smoke sensor works by using a light source, typically a light-emitting diode (LED), and a photosensitive sensor positioned at an angle to the light beam. Under normal conditions, the light travels unobstructed. However, when smoke particles enter the sensing chamber, they scatter the light, causing some of it to reach the photosensitive sensor. This change triggers the alarm, indicating the presence of smoke.
A photoelectric smoke detector uses a light sensor and a light source to detect smoke particles in the air. When smoke enters the detector, it scatters the light, triggering the alarm.
Sensors do not make an engine smoke, unless one is causing the engine to run rich.=Black smoke = Overly rich fuel/air mixture.==Blue smoke = Burning oil.==White smoke = Coolant entering the combustion chamber.==The O2 Sensor would be suspect if it is running rich.=
02 sensor
why could there be black smoke coming out my 2000 calalier
A bad air filter can cause black smoke or bad fuel injector and maf,tp sensor
to add, if you are getting black smoke out of your exhaust, your problem would be related to a fuel issue. Couldbe that your choke is sticking in your carb. Some carb cleaner usually does the trick ridding of the carbon which causes parts to stick. FYI: black smoke=fuel, white smoke=water, blue smoke is oil.AnswerIn my experience the o2 sensor is bad. Just replace the oxygen sensor. check for corrosion at coolant temp sensor or unplugged or possibly bad coolant temp sensor
No, unless the smoke alarm remains accessible and is supplemented by another sensor that is NOT covered up.
Whatever they have been designed to measure. Different sensors are designed to measure different things.
A dual sensor smoke alarm offers better protection because it can detect both fast-burning and smoldering fires, while a traditional smoke alarm may only detect one type. This increases the chances of early detection and provides more comprehensive safety in case of a fire.
