Abstract

Two-wheeled vehicles, especially motorcycles that we have encountered and used in the life of our surroundings in general people within the city of Bengkulu. Ignition System CDI (Capacitor Discarge Ignition) has always played an important role in motor vehicles. CDI ignition system can be interpreted as a whole in the heart in a series of two-wheeled vehicles. The authors conducted research on the use of a comparison with the standard AC-CDI of racing AC-CDI the engine performance. This research was carried out by varying the rear wheel rotation is 240 rpm, 250 rpm, 260 rpm, 270 rpm and 280 rpm in perseneling reduction of 1 and perseneling reduction of 2. The parameters obtained are Torque, Power and Specific Fuel Consumption (SFC). Standard AC-CDI perseneling reduction torgue of 1 = 4.3274 Nm, engine rpm 7466.34 rpm. Racing AC-CDI fueled pertamax higher torque value, the lower the engine revolution.Perseneling reduction torque of 1 = 6.2016 Nm, revolution the engine rpm 7454.08. Perseneling reduction torque of 2 premium = 7.0912 Nm, engine rpm 4465.81 rpm. Reduction torque pertamax = 10.1148 Nm perseneling rediction of 2 and revolution the engine 4484.12 rpm. Rated power perseneling reduction of 1, perseneling reduction power of 1, left = 4.5332 hp, perseneling reduction power of 1, pertamax = 6.4859 hp. In perseneling reduction of 2, premium = 4.4342 hp, perseneling reduction power of 2,pertamax = 6.3936 hp standard AC-CDI power lower its value compared to the racing AC-CDI. SFC value perseneling reduction of 1. SFC perseneling of 1, pertamax = 0.0595 kg / hp.h, SFC perseneling of 1, premium = 0.2614 kg / hp.h, perseneling reduction of 2. SFC perseneling of 2, pertamax = 0.0572 kg / hp.h, SFC perseneling of 2, premium = 0.2273 kg / hp.h. The use of racing AC-CDI generate greater power and greater torque as well as for the specific fuel consumption more efficient than standard AC-CDI.
