Spark plug is one of the important device in SI engine. Standard spark plugs often have troubles firing, which can decrease the speed and reliability of a engine. For enhance the engine performance here we investigated the spark plug ground electrode as well as centre electrode by treated with silicone gel and Cr-Zn oxide for improving the life of spark plug and performance. This reduces the emissions from the engine while also increasing fuel efficiency. Also reduced carbon deposits inside the engine cylinder. This paper evaluated about the silicone gel, Zn & Cr, oxide Coating on the spark plug.
