Q1. What is the function of a spark plug?
A It serves as a lighter to ignite the air/fuel mixture.
It operates under extreme conditions.
Q2 What is the heat rating of a spark plug?
A spark plug must dissipate the heat produced by the combustion gases. The heat rating is a measure of the amount of heat dissipation.
It is essential to use a spark plug with a heat rating that matches a specific engine and its condition of use.
When a wrong heat rating is selected,
When the heat rating is too high,
The spark plug temperature remains too low and causes deposits to build up on the firing end; the deposits provide an electrical leakage path that possibly cause misfire.
When the heat rating is too low,
The spark plug temperature rises too high and induces abnormal combustion (pre-ignition); this leads to melting of the spark plug electrodes that could cause problems such as piston damage.
Q3 How long will a spark plug last?
A Even when a spark plug is correctly used, periodic replacement is required as it is a consumable item.
Examples of problems caused by excessively long periods of use: Worn-out electrodes will have difficulty in sparking.
Deposits accumulated on the firing end may induce abnormal combustion, causing problems that include melting of the electrodes or damaging engine
These spark plugs require replacement.
It must be noted that these phenomena may also be caused by inadequate engine servicing (fuel systems and ignition system) and incorrect spark plug selection.
