THE EFFECT OF USE OF AIR CONDITIONER ON ENGINE VIBRATION IN GASOLINE CAR ENGINES

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 insert ignore into journalissuearticles values(LPG); as an alternative fuel. In this study, the effect of use of Air Conditioner insert ignore into journalissuearticles values(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.
