Re: major misconception about ignition spark

[mark krawczuk]

hi, how does the spark know how much voltage is required? do i have to tell it? if you have a  coil that puts out  60,000 then thats what it will put out at the plug. how come, ive had ign systems in top condition,  then changed over for a high voltage performance  coil ( mallory, for instance) and there was a  NOTICABLE  improvement?   that like saying, even though ya car battery is 12 volts, its actually 7 volts..... also,  isnt the spark better if it has more current?     mark k ----- Original Message ----- From: Pete Parnell To: Ozdat List Sent: Thursday, November 28, 2002 10:47 PM Subject: major misconception about ignition spark Guys,     THE SPARK WILL USE ONLY THE REQUIRED AMOUNT OF VOLTAGE REQUIRED TO IGNITE THE CUMBUSTED MIXTURE.   This means that if your plugs, leads and other spark carying components are in good condition the spark may draw say 25kV.  That is even if you have a 'wam bam extra high voltage U beaut 60 000 volt coil you will staill only require a 25 000V spark.  The only need for high voltage spark is 1. if the combustion gas requires it (ie high compression performance engine) or 2. of you have dodgy ignition components.  A 60 000 Volt coil/ignition module does not give a 60 000 V spark.  Two spark plugs fired together does not give a higher spark potential on the firing cylinder.   Pete. --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
