WebThese plugs must be gapped to precisely 0.022" (0.56mm) using a spark plug gap tool! The replacement interval with these plugs is about half the OEM Bosch plug. These plugs will need to be changed every 15-20,000 miles. Just like ignition coils, spark plugs are key to the performance and efficiency of your BMW engine. http://everything.explained.today/spark_knock/
WebFactors affecting knocking in SI engine: Advancing the spark will result in more compression during sparking. The increase in temperature during the sparking will be higher, hence the tendency to knock will increase and by retarding the spark, the tendency to knock will decrease. The effect of inlet air temp is the same as the compression ratio.
WebPrevious work has demonstrated that knock in the spark-ignition engine is a phenomenon confined to the last part of the charge to burn, and that it is the chemical reactions in this ‘ end-gas ’ which determine whether or not knock will occur. t-shirt suppliers durbanWebEngine knocking at low engine speeds of 20 to 30mph is often spark knocking caused by low octane fuel or old fuel.
