China’s fuel quality standards and fuel supply management have long been an impediment to improved air quality by hindering the progress of vehicle emission control. This paper summarizes the status of China’s fuel quality standards, fuel supply and vehicle emission standards focusing on the major problems of fuel quality management. The mechanism that China uses to establish its fuel quality s...

The Fuel Quality Standards Act 2000, which received Royal Assent on 21 December 2000, provides the framework for a national fuel quality standards regime. This legislation has been developed in response to an urgent need to address the quality of fuel currently available in Australia. New vehicle emission standards, harmonising Australian standards with international vehicle emission standards,...

The main objective of this paper to discuss the research output for getting better engine performance with lower noxious emissions by improving the fuel quality. The control of diesel fuel properties as a means of Regulated pollutants continues to be charged with reaching various air quality goals. Some additives play effective role in diesel fuel for improving fuel‟s quality and minimize the p...

The quick growth of vehicles is due to fast urbanization in mega cities during last decades. This phenomenon has serious impacts on air quality, as emission from mobile vehicles is the major source of air pollution. As a result, any attempt to reduce the emitted air pollutants is needed. This study aims at improving the fuel quality in transporting system with particular emphasis on taxis in Te...

In this paper, the sensor selection approach is investigated with the aim of using fewer sensors to provide reliable fuel cell diagnostic and prognostic results. The sensitivity of sensors is firstly calculated with a developed fuel cell model. With sensor sensitivities to different fuel cell failure modes, the available sensors can be ranked. A sensor selection algorithm is used in the analysi...

With a view to understanding the air-fuel mixing behavior and the effects of the mixture quality on the emissions formation and engine performance, a new quantitative factor of the in-cylinder air-fuel homogeneity named Homogeneity Factor (HF) has been developed. Its characteristics under various injection conditions and air swirl motions within the cylinder have been investigated with CFD simu...
