Comparison of Different Vehicles Driven by Alternative Fuels and Hybrid Driveline Focusing on Emission, Efficiency and Economy (original) (raw)

Reducing Gas Emissions from Transport by Introducing Hybrid Electric Vehicles

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science

The work presents one of the most serious problems related to air pollution as it can have effects both in the short term, but especially in the medium and long term. By increasing the number of automobiles put into circulation every year, in addition to the increase in fuel consumption, the problem of pollution has been accentuated, due to the noxious emissions of the internal combustion engines used for their propulsion. The requirement to reduce fuel consumption has become even more acute as it is closely related to environmental pollution.

Comparison of the environmental damage caused by vehicles with different alternative fuels and drivetrains in a Brussels context

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2003

A comprehensive methodology has been developed to compare the environmental damage caused by vehicles with different alternative fuels, such as CNG, LPG, etc., and drivetrains, such as electric and hybrid drives. This paper describes how the environmental effect of vehicles should be defined and includes parameters concerning vehicle emissions and their influence on human wellbeing and the environment. It then describes how the environmental effect of vehicles could be defined, taking into account the availability of accurate and reliable data. Rating systems are analysed as a means of comparing the environmental effect of vehicles, allowing decision-makers to dedicate their financial and non-financial policies and measures as a function of the ecological damage. Different types of pollution (acid rain, photochemical air pollution, noise pollution, etc.) and their effect on numerous receptors such as ecosystems, buildings and human beings (e.g. cancer, respiratory diseases, etc.) an...

Comparative fuel economy, cost and emissions analysis of a novel mild hybrid and conventional vehicles

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering

Mild hybrid vehicles have been explored as a potential pathway to reduce vehicle emissions cost-effectively. The use of manual transmissions to develop novel hybrid vehicles provides an alternate route to producing low cost electrified powertrains. In this paper, a comparative analysis examining a conventional vehicle and a mild hybrid electric vehicle is presented. The analysis considers fuel economy, capital and ongoing costs and environmental emissions, and includes developmental analysis and simulation using mathematical models. Vehicle emissions (nitrogen oxides, carbon monoxide and hydrocarbons) and fuel economy are computed, analysed and compared using a number of alternative driving cycles and their weighted combination. Different driver styles are also evaluated. Studying the relationship between the fuel economy and driveability, where driveability is addressed using fuel-economical gear shift strategies. Our simulation suggests the hybrid concept presented can deliver fue...
