Question

(T/F) A cold plug is designed so that the insulator tip is reasonably short to hasten the rate of heat transfer from the tip through the spark plug shell to the cylinder head,

Answer 1

A cold plug is designed with a shorter insulator tip to enhance heat transfer from the tip to the cylinder head, ensuring that engines operate effectively within the correct temperature range.

Step-by-step explanation:

True. A cold plug is specifically designed to transfer heat quickly from the insulator tip to the spark plug shell and then to the cylinder head. The shorter insulator tip in a cold plug assists in hastening this rate of heat transfer. Understanding the function of different types of spark plugs is important in ensuring that engines operate within the desired temperature range, which is vital for optimum performance and longevity.
