COMPARITIVE LIFE CYCLE COSTING FOR OF A GASOLINE AND A HYBRID CAR Digvesh khot , Narendran Neelagandan
The depletion of the fossil fuels is emerging as a concern for the whole world. The major sources for the consumption of this fossil fuel are our vehicles that use much of the oil for their operation. The need has been felt to devise the alternative fuel for our vehicles which should be the sustainable option so that it does not contribute to the environmental impacts rigorously. The objective of the comparative analysis is to know the feasibility of the hybrid car against the petrol car. The procedure adopted for the comparative analysis is to do life cycle costing of both the engines by considering the cost, benefits, maintenance and repairs for both the engines. The weight scoring model was also developed to analyze the feasibility of both the engines on the grounds of terms like safety, comfort, emissions and incentives. After completing the comparative analysis the life cycle costing model and the weight scoring model yield the results which were analyzed and the necessary recommendations were made. The results of the comparative analysis revealed that though the Hybrid cars initially cost more, but if they are run for more than 20,000 miles than the total cost per mile is less than the petrol cars. Also weighing model for both the cars gives more weightage to hybrid cars in terms of emissions and incentives. KEYWORDS: Life Cycle costing, alternative fuels, hybrid vehicles, petrol engines. LITERATURE REVIEW
Today the major problem the whole world is facing is the depletion of fossil fuels. Most of the vehicles run on these fossil fuels. It is estimated that if the consumption of these fossil fuels continues at the same rate then by the end of 2030 the fossil fuels will get reduced by 50% of the current value and the prices will increase by $10/ gallon (Kibert, 2008). To overcome this problem a lot of automobile companies are working on the new design of engine which will work on some other source of energy other than fossil fuels. So hybrid model cars were developed keeping in mind of these problems. The first hybrid car model was developed by Dr Ferdinand Porsche in 1902 using a petrol engine, rotating at a constant speed to drive a dynamo, which charged the accumulators (www.wikipedia.com; 10, 2008). These accumulators fed current to electric motors contained within the hubs of the front wheels. Before this several advancements were made in non-gasoline motors, mainly electric cars (www.wikipedia.com). Such non-gasoline car was invented somewhere around years from 1832 and 1839, by Robert Anderson of Scotland and his electric carriage (www.wikipedia.com; 10, 2008). After that several car manufactures have been working on different technology for a long time and recently hybrid cars were developed (www.wikipedia.com; 10, 2008). Hybrid cars are vehicles driven by hybrid engines, which are any engine that combines two or more sources of power, generally gasoline and electricity (Lipman, et.al, 2003). There are two types of gasoline-electric hybrid cars; the parallel hybrid, and the series hybrid. Both of these use gasoline-electric hybrid technology (Lipman, et.al, 2003). In parallel hybrid cars, the gasoline and electric motors work together to move the car forward. In series, the gasoline engine either directly powers an electric motor which in turn powers the vehicle or charges the battery that will in turn power the motor(Lipman, et.al, 2003). Both these type of hybrid cars use another technology called Regenerative braking which stores the kinetic energy that is created while braking. This energy is stored in a battery which runs the electric motor. (Lipman, et.al, 2003) PROJECT SUMMARY
This project was based on the life cycle costing and the comparative analysis of the hybrid engines and the petrol engines. The goal of the project was to calculate the total cost of both the engines during...
