Turbocharging is becoming a key technology for both Spark Ignition (SI) and diesel automotive engines. As regards gasoline engines, turbocharging can help to reduce CO2 emissions when used in conjunction with other technologies, such as engine downsizing, direct injection and variable valve actuation, all managed on the basis of appropriate control strategies. However, the successful applicatio...

Atmospheric aerosols and particulate matter from a wide variety of emissions sources measurements are conventionally performed by recording PM mass. The ambient standards are written in terms of mass concentrations, and emission regulations are based on mass rates. However, in order to understand better the nature of the mobile source contribution to ambient PM, many research groups are current...

In the present study, an existing commercial light-duty automotive diesel engine is modified to a flexible dual-fuel (FDFE). The FDFE operates with different low and high reactivity dual fuel combinations under temperature combustion (LTC) mode using combined multipoint injection common rail direct systems. can smoothly transit between LTC conventional (CDC) mode. combines SI CI benefits stands...

Biodiesel is one of the best renewable fuels to reduce dependence on petroleum derivatives. The objective this work evaluate mechanical and environmental performance in compression ignition engines with use biodiesel proportions 5 % (B5), 15 (B15), mixtures additive B5A B15A, through experimentation automotive measuring equipment, for mass application vehicles. methodology applied based develop...

The present work aims to assess the influence of composition blends hydrogen (H2) and Natural Gas (NG) on Dual Fuel (DF) combustion characteristics, including gaseous emissions. 3D-CFD study is carried out by means a customized version KIVA-3V code. An automotive 2.8 L, 4-cylinder turbocharged diesel engine was previously modified in order operate DF NG–diesel mode, tested at dynamometer bench....

Development of local technologies is crucial to the sustainable energy agenda in resource-limited countries and world. Strengthening green promoting utilization will reduce carbon emissions that could be generated during transportation delivery products from one country another. In this paper we developed bio-oil/diesel blends using a low-tech pyrolysis system designed for smallholder farmers d...

A manufacturer’s assortment is the set of products that the company offers to its customers. Assortment planning considerably affects both the sales revenue and product offering costs for the company and it had experienced growing attention across different industries over recent decades. In this study, we propose a modeling framework that seeks to identify the optimal assortment for a manufact...
