you might have a short in the electrical system
the motor could pre-detonate or "knock" that can cause damage
she could knock all the air out of it and cause it to die
No, it will not cause the engine to knock.
Do you mean the knock sensor? It's a device that detects engine knock so that the computer can retard the timing. If the knock sensor isn't functioning, it could be a connector or the sensor.
If the knock sensor failed the CEL (Check Engine Light) would be illuminated and the engine may "ping" or "spark knock" under load. Serious "spark knock" can damage the engine if allowed to continue.
A knock sensor assures that you're getting as much power and fuel economy as is possible from your engine. More details: A knock sensor allows the engine to run with the ignition timing as far advanced as possible. The computer will continue to advance the timing until the knock sensor detects pinging. At that point the computer retards the ignition timing just enough for the pinging to stop. The knock sensor responds to spark knock caused by Pre-detonation of the Air/Fuel mixture. As the flame front moves out from the spark plug ignition point, pressure waves in the chamber crash into the piston or cylinder walls resulting in a sound known as a knock or ping. This is caused by using a fuel with a low octane rating, overheating, or over advanced timing. Sometimes it can be caused by hot carbon deposits on the piston or cylinder head that raise compression. A knock sensor is comprised of Piezoelectric materials; Crystals that when impacted, generate a voltage (same idea as a BBQ ignitor). This voltage is monitored by the computer, and when an irregularity is detected, the computer corrects timing in VVT (variable valve timing) engines, or triggers a DTC Diagnostic Trouble Code) in older vehicles.
yes when it is not working properly
Rod or main bearings. Those are located on the crankshaft.
you have oo knock your head on something hard and pass out this could cause notcia(pronounced nor-zi-a)
No, knocking in an engine is normally more serious than a gasket leak. Depending on how heavy the knock sound is it could be the Big Ends bearings need changing or it if its fainter than that it could be the timing is out. Either way it can cause real damage to the engine and should be repaired as quickly as possible. Have seen exhaust manifold gasket leaks that are described as a 'knock' by inexperienced persons. Normally a knock is piston connecting rod bearings that have gone out.
The knock sensor sends a voltage pulse to the computer whenever it detects the vibrations caused by metal, such as the conditions caused by the spark knock. When the knock sensor sends a voltage pulse, the computer retards the timingin an effort to stop the spark knock.
Not sure exactly what you're asking, but yes, you can knock a runner over by tripping into them. All it really takes is a hard shove, because a runner's feet rarely touch the ground at the same time.
