"Knock", sometimes called "ping" is mostly caused by pre-ignition, a function of improperly set timing. Since the advent of computer-controlled ignition, this once-common problem has greatly diminished. When it happens in modern cars, it can be caused by a buildup of carbon in the cylinder heads, which is usually traced to cheap, bargain-brand (non-labeled) gas. The last car I owned that developed a problem with pre-ignition was a 1980 Chevrolet Chevette, and that was only after it passed 85,000 miles.
It's time for a new engine.
No, it will not cause the engine to knock.
the motor could pre-detonate or "knock" that can cause damage
check the anti knock sensor on the side of the motor
it reads if your motor is knocking. say bad rod bearings or loose valves. it will kick your check engine light on if it reads knock from the motor.
Knock on wood means you are hoping that it happens.
Motor
A knock sensor detects engine knock in the motor(aka pinging, detonation, or uncontrolled explosions. it basically means the motor is about to blow up or potentially could.) the second part to a knock sensor is that it keeps the ignition timing as advanced as possible to make the most power without making engine knock. So if you have a bad knock sensor or have a check engine light form a knock sensor your car will be slower. this is when your car goes into LIMP mode which is basically a preset running condition which is safe for the motor.
Entering a House - "Ko ko!" means "Knock knock!"
knocking as in spark knock? or engine knock? spark knock is adjusted through a knock sensor via ignition timing. eng. knock is due to brg. knock as in low oil pressure or sluge in engine or just a tired motor
if it has a knock that is not the issue, cooling fan relay goes bad, they run hot & develop a knock inside the motor
knock each other out
