Question

What is the firing frequency equation?

A) Engine rpm multiplied by the number of cylinders.
B) Engine rpm multiplied by half of the number of cylinders.
C) Engine rpm multiplied by twice the number of cylinders.
D) Engine rpm multiplied by three times the number of cylinders.

Answer 1

The firing frequency equation in an engine is calculated by multiplying the engine RPM by the number of cylinders.

Step-by-step explanation:

The firing frequency equation in an engine relates to the number of times the spark plugs fire in a given time period. The equation is calculated by multiplying the engine RPM (revolutions per minute), denoting how fast the engine rotates, by the number of cylinders in the engine. Thus, the correct formula is Engine RPM x Number of Cylinders.
