The purpose of this chapter is to discuss the uses of non-precious metals for the development catalytic converters. Copper powder and nickel catalyst were chosen as the alternative catalysts to reduce the use of precious group metals (PGMs) platinum, palladium, and rhodium. Simulation by COMSOL has shmcvTI that Nickel and copper were very effective

The purpose of this chapter is to present the results of an experimental study ofthe performance of ceramic monolith three-way catalytic converters (TWCC) employed in automotive exhaust lines for the reduction of gasoline emissions. Two ceramic converters of different cell density, substrate length, hydraulic channel diameter and wall thickness wer

The purpose of this chapter is to present the results of an experimental study of the performance and conversion efficiencies of ceramic monolith three-way catalytic converters (TWCC) employed in automotive exhaust lines for the reduction of gasoline emissions.

This chapter provides the detailed information involved in the design of the Second generation InJM buggy car project. Part I includes all details regarding the method of design, design's philosophy, concept and model construction and result evaluation. Background research and literature review have been done in order to provide a basic referen

This chapter describes part of the detailed methodology of relationship between noise and back pressure for muffler design. Starting with a brief introduction, an attempt is made here to present different steps of muffler design considering the relation between noise and back pressure. The design ofthe muffler chamber separation and arrangement is

This chapter provides the detailed information involved in the fabrication of the Second generation HUM buggy car project. Part II includes all details regarding the fabrication process Background research and literature review have been done in order to provide a basic referenc for this buggy car design. Analyses have been carried out extensively

The exhaust system consists of the exhaust manifold, the header, the catalytic converter, the muffler, and the tailpipe. Certain flow characteristics must be met for the optimal performance of the exhaust system. The main objective of this chapter is to design exhaust system (particularly the exhaust manifold) using GT-Power software and to optimiz

This chapter describes the final part of the detailed methodology of relationship between noise and back pressure for muffler design. This part includes experimental setup, experimental procedures, results and discussions. The experimental data show a general shape of an average design ofthe muffler which would be the most suitable for the test car

A mixed 110\\ impeller has heen used as an alternative mixing strategy for hiodiesel production. in order to comhine salient hydrodynamic features and overcome stagnation during mixing. This unique comhined radial and axial flow is presented is to show the advantage of this impeller. The numerical simulation of this impeller was carried out using t

Dhaka, capital city of Bangladesh, with a population of 12 million, receives 300,000 to 400,000 rural migrants annually. During last three decades, city population has grown over 7%, annually. Bastee population of city has grown from 1.0 million in 1990 to 3.4 million in 2005. Several policy approaches such as eviction, resettlement and upgrading,
