The world’s climatic conditions rises and there is a demand for environment friendly vehicle designs. The automobile industry strives hard to ensure low carbon emissions. This refers to the mass reduction and fuel consumption. This paper investigates to achieve the overall Body-in-white (BIW) bending and torsion stiffness performance using Topology optimization and light weight internal reinforcements. The potential opportunity of achieving light weight structure using the efficient way of defining the internal reinforcements has been investigated. BIW at the conceptual design phase has been considered for the research. Topology optimization was performed considering the roof rail and the rocker as the design space with an approach of achieving the improved torsion and bending stiffness performance. The optimized bulk head design locations have improved the BIW stiffness performance with minimal mass increase in the BIW. This method can be widely used at various stages of the BIW design to identify the weaker sections and then design the load path using internal reinforcements effectively. The optimized internal reinforcements has achieved higher torsion and bending performance with minimal mass addition.Keywords

Compression ignition engines are widely used due to their lower energy consumption and enhanced combustion efficiency. In this experimental investigation, the feasibility of fuelling a single cylinder 4 stroke direct injection compression ignition engine with methyl esters of palmkernel (PME) oil along with various fractions of aluminium oxide nano particles (ANOP) were analysed. Two stage transesterification process was adopted to prepare PME. PME20 blend was formulated and fused using high speed homogenizer with varying proportions of AONP as 25 ppm, 50 ppm and 100 ppm in the presence of hexadecyl trimethyl ammonium bromide as surfactant. The experimental investigations were conducted at rated power of 3.5kW at 1500rpm. It was noticed that supplementation of AONP affected the ignition delay significantly favouring enhanced combustion efficiency. The rate of heat release and in-cylinder pressure was substantially increased with notable reduction in ignition delay. Addition of AONP showed an increase in brake thermal efficiency and exhaust gas temperature with diminution in brake specific energy consumption. The unburned hydrocarbons, carbon monoxide and smoke density decreased sharply with an upsurge in NOx. Increase in AONP concentration up-to 100 ppm with PME20 was found to give better combustion and performance characteristics.Keywords
