DESIGN AND CONSTRUCTION OF A FUELLESS AUTOMOBILE (ELECTRIC) MACHINE FOR TOWN SERVICES USING TRICYCLE ENGINE STANDARD

ABSTRACT This project is Design and Construction of a Fuelless Automobile (Electric) Machine for Town Services Using Tricycle Engine Standard. The tricycle uses an electric brushless direct current motor connected to the rear wheels of the tricycle using the chain and sprocket mechanism. This motor is powered by direct current from the battery bank. The battery bank is charged via a solar PV system directly installed on the roof of the tricycle. This enables the panel to charge the battery bank while the tricycle is in motion. The tricycle also employs the regenerative braking system which also charges the battery every time the brake is initiated. If effectively deployed, an estimated 32tonnes of CO2 emissions is calculated to be the CO2 savings effected by this energy system annually. Conclusively, this paper addresses the need to provide a sustainable and affordable solution to commercial passenger transportation in developing countries of the world. Full wave bridge rectifier At this stage, D2 and D3 are reverse biased and thus only negligible leakage current will flow through. This implies D2 and D3 do not allow current to pass through in the opposite direction and thus the diodes behave like a switch At the opposite half cycle D2 and D4 are now forward biased, thus current flows out of the lower part of the transformer through D2 to the load and then to the ground and also up from the ground to the upper part of the transformer through D4 and D1 and D3 are now reverse biased.

The availability and the cost of the raw materials needed for this fabrication will pose as a major challenge. The Bill of Engineering Measurement and Evaluation (BEME) was used to get the list of work items, their estimated quantities and cost prepared from the specification and drawings of a project. The BEME serves as a tool for estimating the cost of construction of the project before, during and after its implementation and also a part of the tender documents.
