Abstract

Air conditioning in automobiles is done
by air conditioning compressor driven by the engine. The engine exerts a
specific power to run air conditioning system. During running, fuel
consumption, noise and vibration increase. Most of gasoline automobiles in
Turkey have used Liquefied Petroleum Gas (LPG) as an alternative fuel. In this
study, the effect of use of Air Conditioner (AC) on engine vibration in
gasoline car engines are experimentally investigated. According to the
experiment results, it is observed that the use of AC while running on LPG decreases
the engine vibration at the revolution speeds of 800, 2000, 3000 and 5000 rev/min
whereas the use of AC while running on gasoline decreases the engine vibration
at the revolution speeds of 2000, 3000 and 4000 rev/min. In addition to that,
when the AC is on, the levels of vibration increase in the engine while running
on LPG and gasoline are observed to be linear and nonlinear with the increase
in the idle revolution speeds, respectively. Accordingly, it can be concluded
that the car engine while using LPG is running more stably compared to that
while using gasoline.
