The primary function of the spark plug is to ignite the air-fuel mixture within the combustion chamber under any operating condition. So first of all, if it were not for him I wouldn't be here with all of this knowledge today. Choose brandname and start typing model number. Pre-ignition occurs when the air-fuel mixture is ignited by a hot object/area in the combustion chamber before the timed spark event occurs. For this reason, most racers add high-energy ignition systems. Xiaomi Redmi 6. I only wish I could thank her in person and show her these videos. INDEXING. Let us know. 0000008169 00000 n Those with modified engines must remember that higher compression or forced induction will typically require a smaller gap setting (to ensure ignitability under higher pressure). Register Today It's free! The insulator nose of a hotter spark plug has a longer distance between the firing tip of the insulator and the point where insulator meets the metal shell. My very first manager (Mr Nadin), who gave me a chance straight out of school despite me not being the most ideal candidate for the position of engineers apprentices at the time. hb```b``# Heavy knock can cause breakage and/or erosion of combustion chamber components. Also, if too many washers are added, the firing end of the plug will not be as far into the combustion chamber and performance can decrease. Sure, ad-blocking software does a great job at blocking ads, but it also blocks useful features of our website. So the motor would run and should not take any damage by using the plug that does not stick as far into the chamber than the stock spark plug.

As a general guideline, among identical spark plug types, the difference in tip temperature from one heat range to the next is approximately 70C to 100C. If an air-fuel ratio meter or gas analyzer is not available, it will be necessary to visually inspect the spark plugs frequently during the tuning process to determine the proper air-fuel mixture. When the spark plug firing end (tip) temperature exceeds 800C, pre-ignition originating from the overheated insulator ceramic can occur. 3341 0 obj <>stream Spark plugs have been around as long as internal combustion engines have and are often a misunderstood component. A colder heat range spark plug may be necessary if the ignition timing has been advanced to near the knock level. Pre-ignition will dramatically raise the cylinder temperature and pressure, which can melt and hole pistons, burn valves, etc. 3301 41 In identical spark plug types, the difference from one full heat range to the next is the ability to remove 70C to 100C from the combustion chamber. Products with electrical plugs are designed for use in the US. Specifications. When the spark plug firing end (tip) temperature exceeds 800C, pre-ignition originating from the overheated insulator ceramic can occur.

The two colliding flame fronts contribute to the knocking sound. The spark plug heat range has no relationship to the electrical energy transferred through the spark plug. I really hope that all of my tutorials are understandable by most, if not all, people who wish to view them. The heat rating of each NGK spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type. If the air-fuel mixture is not properly richened, and the mixture is too lean, higher cylinder pressures/temperatures, knocking, and the subsequent increase in the spark plug tip temperatures can result. The spark timing can be advanced further because ethanol blend fuel has a higher resistance to knock (higher octane). NGK Spark Plug, CMR7H. Higher altitude = less air = less fuel.
