There are many factors that affect the operation of vehicle
engines. Not working regularly of an engine causes a decrease in the
performance; on the other hand, an increase in the fuel consumption, the
vibration and the HC emission. These adverse impacts reduce vehicle comfort and
increase travel costs, and also damage nature much more. Vehicles are normally
designed in such a way that they provide optimum operating parameters. However,
as the vehicle is used, these parameters negatively change. In this study, it
has been investigated that the effects of spark plug gap on vibration, noise
and HC emission in a gasoline engine. It is a fact that, the spark plug is
abraded in a certain amount because it is continuously ignited. This abrasion
increases the distance between the center electrode and the electrode head, and
changes the quality of the composed spark. In experiments, it has been detected
that, when the spark plug clearance and the number of revolutions are
increased, the vibration and noise increase proportionally; on the other hand,
the exhaust emission (HC) value increases at 0,7 mm, 0,8 mm and 1,0 mm plug gap
and decreases at 0,9 mm plug gap. As a result, setting the standard spark plug
gap in the gasoline engines to 0,9 mm instead of 0,7 mm can provide a
significant reduction in exhaust emissions; thus, an improvement in performance
can be achieved.
