PENGARUH PENAMBAHAN RANGKAIAN DARLINGTON SISTEM PENGAPIAN DAN PUTARAN TERHADAP TEGANGAN JARUM YANG DIHASILKAN PADA MESIN KIJANG TYPE 5 K

Abstract

Abstract: Vehicle technology development in this era pushes every vehicle industry to compete tightly in producing of practical, economic and environmentally sound vehicles. Recent fact shows that there are so many vehicles in its operation failed in having correct specification, creating wasteful of fuel consumtion and bad emission through certain limit. Economically, in reaching thrift gasoline with optimal power, it can increase the needle voltage  which is resulted when plug jumped a fire and started the ignition. The research aimed to test the difference between the use of circuit of Darlington ignition system to the needle voltage  in vehicle at low, middle, and high rotation of Toyota Kijang 5K motor. The data collection was done by testing needle voltage in vehicle which used conventional ignition system and Darlington serial ignition system. Research method used was testing the needle voltage which is resulted from conventional ignition system and Darlington ignition system by using factoral 2x2 Design. The results show that the use of Darlington serial ignition system in every motor rotation caused a significant difference with ratio F = 10,214 and P<0,005 to the needle voltage of Toyota Kijang 5K. Its averages show that by using Darlington circuit System in ignition system, it can get higher needle voltage than conventional ignition system.
