The Impact

A Monte Carlo simulation methodology is suggested in order to assess the impact of ambient wind on a vehicle’s performance and emissions. A large number of random wind profiles is generated by implementing the Weibull and uniform statistical distributions for wind speed and direction, respectively. Wind speed data are drawn from eight cities across Europe. The vehicle considered is a diesel-powered, turbocharged, light-commercial vehicle and the baseline trip is the worldwide harmonized light-duty vehicles WLTC cycle. A detailed engine-mapping approach is used as the basis for the results, complemented with experimentally derived correction coefficients to account for engine transients. The properties of interest are (engine-out) NO and soot emissions, as well as fuel and energy consumption and CO2 emissions. Results from this study show that there is an aggregate increase in all properties, vis-à-vis the reference case (i.e., zero wind), if ambient wind is to be accounted for in road load calculation. Mean wind speeds for the different sites examined range from 14.6 km/h to 24.2 km/h. The average increase in the properties studied, across all sites, ranges from 0.22% up to 2.52% depending on the trip and the property (CO2, soot, NO, energy consumption) examined. Based on individual trip assessment, it was found that especially at high vehicle speeds where wind drag becomes the major road load force, CO2 emissions may increase by 28%, NO emissions by 22%, and soot emissions by 13% in the presence of strong headwinds. Moreover, it is demonstrated that the adverse effect of headwinds far exceeds the positive effect of tailwinds, thus explaining the overall increase in fuel/energy consumption as well as emissions, while also highlighting the shortcomings of the current certification procedure, which neglects ambient wind effects.

Secondary Information

Objective- a study has been conducted to scrutinize the vehicle production and sales by segment in ASEAN. Methodology/Technique- The study is prepared grounded on primary evidence and secondary material. The primary evidences have composed through oral interview from stalwarts of automotive industry. The secondary information has collected from the reports of international Insight of automotive industry and all existing literature has obtained from internet automotive websites, auto business magazines, and e-auto journals. Findings- Outcome of the research divulges that, in vehicle production and sales by segment i.e. Light Commercial Vehicle (LCV), Large Size and also Compact Vehicles in ASEAN expected to increase further in future years, so the Automotive Industries of ASEAN should uninterruptedly participate in Research and Development in order to keep up with their Global competitors in terms of technological advance. Novelty - ASEAN countries would implement the thoughtful and achievement policies in Automotive Industry in agreement to the auto information and world-wide automotive industry competition tendency, to enhance the development of automotive industry.
