Recent trends in Four-Stroke Internal Combustion Engines of Two-Wheelers

This paper deals with highlighting the improvisations in the working of a two-wheeled four stroke internal combustion engines. The efficiency of these small engines were enhanced with increased power output just by increasing the number of fuel igniting element i.e. Spark Plug. Conventional engines employed a single spark plug in its engine for igniting the mixture of fuel and air. But to have more effective burning of the mixture in order to increase the power output and reduce the wastage of this mixture as unburnt, the number of spark plug was doubled for efficient burning of the mixture. Two spark plugs helped in igniting the fuel from two directions rather than one, as in conventional engines. This new technology was termed as “Twin Spark Ignition System”. Although this technological trend proved to be sufficient, a new well-improvised ignition system was given birth and named as “Triple Spark Technology” involving the use of three spark plugs rather than one or two. A detail about this trend in IC engine is discussed below.
