A method of reducing the conductivity of deposits on spark plugs formed from the combustion of a fuel comprising ferrocene, said method comprising adding a manganese-containing compound to the fuel, wherein the manganese-containing compound is chosen from the group consisting of cyclopentadienyl ...
fuel contains tungsten or tungsten compound will interact with iron resulting from the combustion, and reduce iron deposits on spark plugs, valve seats, exhaust system; prevent leading to sparkplug failuredoi:US7794512 B2The present invention relates to an apparatus and method for delivering tungsten...
The system comprises producing a spark discharge operative to ignite a mixed gas in an usual manner and selectively producing a purifying and sweeping spark discharge operative to remove carbon deposited on said creeping discharge path. An ignition circuit for carrying out the system is also ...

The method may further include selectively generating an indication of a recommendation to change one or more spark plugs of the ignition system based upon a primary current measured after the dwell period.
A special form of combustion chamber deposits, well known under the synonym spark plug fouling, is a carbon needle on spark plugs, which can cause the total damage of the catalysts (Japanese Industrial Standard D 1606: Adaptability Test Code of Spark Plug for Automobiles). The Coordinating ...
Spark ignition enginesA four-cylinder engine with a slice between the head and the block carrying instrumented plugs has been used to study the growth of combustion chamber deposits and knock. Deposit thicknesses vary substantially at different locations, the thickness generally being greatest at the...
