Performance analysis of Asykar Urban Gasoline energy saving car braking system

Abstract

Asykar Urban Gasoline is an energy efficient car which is made by students of Riau University. The car consist of multiple system to run properly such as steering system, electrical system, engine system, transmission system and braking system. In order to participate in the energy-efficient car event (KMHE), Asykar Urban must meet several requirements according to regulations, one of which is the condition of the brake system, because brake system affects driver safety and fuel consumption. This research aims to analyze the braking system, due to it is vital role and also effects the fuel consumption of the car. It is done on 2 types of roads: asphalt and concrete (dry and wet) with 3 speed variation of 25 km/h, 35 km/h, 45 km/h. The result show that the highest braking distance on wet asphalt within 45 km/h is 7.96 m theoretically and 7.5 m on field with 5.7% error. Next, braking distance with the biggest range among all data is on the wet asphalt within 35 km/h velocity and braking distance of 4.83 m theoretically and 4.3 m on field with 9.93% error. It means the amount of range in general is not really big which not exceeding 10%. Results also show the stabilization of the car tends to over steer regardless on theoretical calculation or in actual test.
