Abstract

The study was conducted by varying pully diameters of 70, 73, 82 mm where all three variations of this diameter were testedthree times each. Testing was conducted on rounds of 1000, 1900 and 2500 rpm engines. And in conclusion the researchersstated that there is an effect of the increase in the rotation of the machine and the pully diameter of the alternator on theoutput voltage of the alternator but has no effect on the output current of the alternator, at each turn and at any pullydiameter size there is no significant effect on the slow or rapid charging of the batrai. Slow or fast charging of the batterydepends heavily on the size of the current used and usually the large current used is 10% of the battery capacity charged.

Abstract

Motorized vehicles are generally equipped with a driving engine which functions as a driver for the car. Motorized vehicles have engines consisting of one cylinder, two cylinders, three cylinders, and so on, and all of them require air as a medium for burning fuel in the combustion chamber to produce power to drive the vehicle. Motorized vehicles, both at sea and on land, operate at different air temperatures in all corners of the earth. This research was carried out by varying the air temperature entering the combustion chamber. The intended temperatures are 20oC, 25oC, 30oC, 35oC, and 40oC, and what will be examined is fuel consumption, HC, and CO exhaust emissions. The research results show that air temperatures from 20 to 40 degrees do not significantly affect fuel consumption or HC and CO exhaust emissions.
