รถประหยัดน้ำมันเชื้อเพลิง

Abstract

Nowadays the fuel energy is consumed more than it was used in the past and most of energy used comes from petroleum which is not reuseable. Morever, the crude oil which is raw material to be refmed is likely to take place in nature; it usually takes a long time. Therefore, this natural resource must be used efficiently to maximize its benefits. Contructing Econo Power Car will be one ofmany methods to decrease the energy consumption. The Econo Power Car was designed to be water drop in order to reduce the wind resistance. The body was designed to cover all parts in order to decrease the circulation of air and the lightweight aluminium alloys were the materials to use. Besides the engine was improved to increase the complete combustion by adding 2 more spark plugs and an inlet valve rocker arm slide was installed to reduce the energy consumption ofthe engine while it was turn off. The test to fmd out the economy rate was done by collecting data based on the theory from the Automotive Engineering. The crucial factors affecting the economical fuel consumption was frictions which were friction of the road and friction of the air. Therefore, the design to be water drop-shaped with closed cover was done to reduce friction and the wheels were adjusted everytime before competition. The results revealed that it archieves the goal. From the 7th Honda Econo Power it could save energy at the rate 543.018 km per litre at the speed 25 km per hours.
