thus avoid the creation of hot spots around the combustion chamber that could ignite the fuel , ... which in turn limited the compression ratiocausingpre - ignition ( knocks

thus avoid the creation of hot spots around the combustion chamber that could ignite the fuel ,causingpre - ignition ( knocks

too lean of a air / fuel mixture ( not enough fuel to mix with the available air ) or too much ignition advance for engine load and throttle position combined with a lean mixture or excessive carbon d(passive) is generally caused bypre - ignition

Detonationcausesearly ignition

heat buildup in engine components or overheating of the air - fuel mixture during compression(passive) is caused byPre - ignition

a mixture ... , vacuum leaks , too much spark - advance causing pre - ignition , overheating , insufficient octane in the fuel ( if high - compression 350causingpre - ignition

by timing , low octane fuel , and high cylinder temperatures(passive) can be causedPre - ignition

One of the causes of hot - spots is carbon deposits in the engine headcausingpre - ignition

_ Engine designed with too high compressioncausingpre - ignition

by low octane fuel or incorrect engine timing(passive) caused bypre - ignition

an ignition source other than the spark plug , such as hot spots in the combustion chamber , a spark plug that runs too hot , or carbon deposits in the combustion chamber(passive) is caused byPre - ignition

A lower octane in a high - compression enginecan resultin pre - ignition

when the fuel in the chamber is ignited prior to the spark in the normal combustion process(passive) is causedPre - ignition

improper spark plug temperature , incorrect timing , carbon deposits in the cylinder(passive) can be caused byPre - ignition

the heat from the compression processcan causepre - ignition

small hot spots in the combustion chamber which may be carbon or similar(passive) is caused byPre - ignition

A plug that 's too hotwill causepre - ignition

That can cause the engine to run hotcausingpre ignition

too much spark advance or too low octane gas(passive) can be caused byPre - ignition

the temperature of spark plug ... so highto causepre ignition

by the high compression and timing(passive) caused bypre - ignition

by high - compression engines(passive) caused bypre - ignition

a mixture ... , vacuum leaks , too much spark - advance causing pre - ignitioncausingpre - ignition

Operating conditions at increased engine speed and engine load ... more likelyto causepre ignition

an ignition source other than the spark produced by your spark plugs , such as hot spots in the combustion chamber , a spark plug that runs too hot for the application , or carbonaceous deposits in the combustion chamber heated(passive) is caused byPre - ignition

by hot spots in the combustion chamber , such as on a spark plug or exhaust valve , or on carbon deposits(passive) are causedpre - ignition

point sources of heat ... depositsmay causepre - ignition

the incorrect timing of the spark to the plug or some other means of ignition that does not require the spark from a plug(passive) can be caused byPre - ignition

hot spots " in the combustion chamber which ignite the charge prior to the spark(passive) is caused byPre - ignition

too much spark - advance ... if high - compression 350causingpre - ignition

carbon deposits in the engine headcausingpre - ignition

hot spots like the tip of a spark plug or carbon deposits(passive) is often caused byPre - ignition

In such a case it will act as ignition source to ignite the mixture of fuel and air before the supply of sparkthus causingpre - ignition

too much advance , hot carbon deposits in the chambercausingpre - ignition
