“…Other cities, such as Toronto, Canada [12], Iran [13], and Singapore [14] also have adopted local driving cycles. Local governments in Malaysia continue to use the NEDC for legislative purposes, as well as local manufacturers and suppliers for evaluation [15].…”

Over the years, many models have been created to estimate pollution inventories and fuel usage. These models can be divided into two types: travel-based and fuel-based. One of the most used travel-based models for estimating emission inventories is driving cycles. It can be used for a variety of different things, such as establishing pollution regulations, traffic control, and calculating journey time. For these goals, researchers have previously attempted to use easily available, well-established driving cycles. In many ways, however, the local environment differs greatly from that of the driving cycle's genesis. As a result, these cycles' applications have failed to provide high-quality results. This research aims to analyse the various approaches utilised for driving cycle construction in various locations of Malaysia under varied operational situations.

“…It was observed a huge influence of the shielding gas on the thermal properties (thermal expansion, thermal diffusivity and thermal conductivity) of the weld metal in relation to the base metal (DH36 steel plate). Abas R. H. and Taieh, N. K. [5] measured the thermal diffusivity and thermal capacity in a temperature range (from 1473 K until ambient temperature) for different duplex steels in order to complement thermophysical data of these alloys. Betini et al [6] found low value for thermal diffusivity for pure argon as shielding gas using conventional GTA welding process in heat-affected region.…”

This study describes the thermal diffusivity of thin duplex steel plates in the thickness direction measured using the laser-flash method after welding. The work reports the experimental efforts in recording temperature profiles of the grade UNS S32304 duplex steel during autogenous welding. The butt weld autogenous joints were carried out by the GTAW (gas tungsten arc welding) process with either argon or argon - 2% nitrogen atmospheres. The amount of nitrogen in the heat affected regions, after welding, was measured and correlated with the variation of the thermal diffusivity of the studied material. The temperature profiles were obtained using k-type thermocouples connected to a digital data acquisition system. Different thermal cycles and thermal diffusivity values were observed in the heat-affected zone (HAZ) for both samples. In the solidified zone (SZ) was observed similar increase of the thermal diffusivity values for the plates welded with pure argon and argon plus nitrogen atmosphere.

“…Besides, in the last years two-wheelers vehicles are increasingly being used and represent a large proportion of motorised vehicles, especially in urban areas of Asia and Europe [1,2]. Starting from these considerations, a numerical-analytical analysis was performed on the cold exhaust emissions of two high-performance motorcycles (1000 cm 3 and Euro-3 legislative category).…”

Modern vehicles equipped with a spark ignition engine come with fuel injection and electronic mixture control, in combination with a three-way catalyst: as a result, carbon monoxide and unburned hydrocarbon cold emissions represent a significant share of total emissions if compared with those given off in hot conditions, so implying direct consequences on the air quality of metropolitan areas. The purpose of this research is to investigate the engine efficiency and emissive performance of last generation engines during the cold-start phase. For this aim, an experimental-analytical procedure was optimised and applied to study the cold emission behaviour of two motorcycles, characterised by similar technical specifications; the exhaust emissions of these motorcycles were measured on a chassis dynamometer in the laboratories of the National Research Council (CNR-Italy). By using this calculation procedure and the emission results measured during the experimental tests, the duration of the cold phase and the total emissions released during the cold-start transient were evaluated for carbon monoxide and unburned hydrocarbons. The average values of cold emission factors and warm-up transient durations obtained for unburned hydrocarbons were 1.05 g/km and 162 s, respectively. Regarding carbon monoxide, the average values of cold emission factors and warm-up transient durations were 14.9 g/km and 152 s, respectively. The results of this study are very useful for better characterising the emission levels of the last generation motorcycles under real urban conditions.
