Abstract
This paper presents a comparison between the energetic efficiency of motorcycles driven by electricity and by different combustion engines. Tests were carried out according to the European standards for motorcycles exhaust emissions (Directive 97/24/EC). Such standard has been adopted by CONAMA for homologation and certification of motorcycles in Brazil. Chassis dynamometer tests simulated road load conditions in cycles with variable speed in normalized time. Work performed during the each test was computed and the fuel energy expenditure along the cycle was measured. The energy efficiency was thus calculated by the ratio between the two. Results show that electric driven motorcycles are three times more efficient than motorcycles than internal combustion engines. Regulated emissions carbon monoxide (CO), total hydrocarbons (THC), nitrogen oxides (NOx) and carbon dioxide (CO2) were measured in the exhaust gases of the combustion engines.
