On some older vehicles, a different type of coolant sensor may be used. Some of these are essentially an on/off switch that opens or closes at a predetermined temperature. The sensor may be wired directly to a relay to turn the electric cooling fan on and off, or it may send a signal...
An oxygen sensor in the exhaust stream makes sure there is enough oxygen available for the catalyst to work and adjusts things if necessary. Besides gas, what else powers your car? The electrical system consists of a battery and an alternator. The alternator is connected to the engine by a...
One of the most common mistakes made by new weed growers is to conduct spur-of-the-moment experiments and hurt or even kill their plants. You should always at least do a quick google search before you try any new technique. Why make your plants be the guinea pig of an experiment that ...
and a computer to monitor and adjust everything. For example, the catalytic converter uses a catalyst and oxygen to burn off any unused fuel and certain other chemicals in the exhaust. Anoxygen sensorin the exhaust stream makes sure there is enough oxygen available for...
With this system, we found a couple of leaks in an intake manifold in five minutes even though we had no idea where to start. It's also good for finding exhaust leaks, as an exhaust leak upstream of the O2 sensor can pull in extra oxygen and mimic a vacuum leak even if it's not...
pond pictures are intended to correspond with the next DIY sections of this article, and some of these images are redundant with the images included in Part 3. If you read something that you’re having trouble visualizing, hop back up here to the slideshow and you’ll probably find an ...
Make yourself big:Make it easier for others to find you. Wear bright colors. Blow your whistle. Make a big X in the ground with sticks or rocks. Animals are afraid of humans:If you hear a noise blow your whistle or yell. If it is an animal, it will run away. If it is a rescue...
The principle of the program is simple:A lost child who stays put is easier to find than one who keeps moving. Initial searches typically focus where the child was last seen. If the child keeps moving, that information becomes less and less helpful. Once an area is searched, resources focu...
The resulting signals from PRRs are processed and integrated to produce an inflammatory response that initiates an immune response to restore tissue homeostasis. An essential family of PRRs is the inflammasome sensor family, cytosolic proteins that upon activation trigger inflammatory signaling and cell ...
If the coolant contains silicates (conventional green antifreeze), it can also foul the oxygen sensor and catalytic converter. If enough coolant leaks into the cylinder (as when the engine is sitting overnight), it may even hydro-lock the engine and prevent it from cranking when you try to ...
