Methodology to Estimate Road Grade Effects on Consumption and Emissions from a Light Commercial Vehicle Running on the WLTC Cycle
Publisher: ASCE
Abstract: A novel methodology is suggested in this study, with the aim of assessing the impact of the road grade on a vehicle’s performance and emissions. This methodology consists of creating multiple sinusoidal elevation profiles ...
Assessment of NOx Emissions during Transient Diesel Engine Operation with Biodiesel Blends
Publisher: American Society of Civil Engineers
Abstract: The target of the present work is to review the literature regarding the effects of biodiesel blends on nitrogen oxide (
Numerical and Experimental Study by Quasi-Dimensional Modeling of Combustion and Emissions in Variable Compression Ratio High-Speed Spark-Ignition Engine
Publisher: ASCE
Abstract: This work presents the development and use of a comprehensive, quasi-dimensional, two-zone combustion model aiming at predicting the combustion characteristics, performance, nitric oxide (NO), and carbon monoxide (CO) ...
Combustion Instability during Starting of Turbocharged Diesel Engine Including Biofuel Effects
Publisher: American Society of Civil Engineers
Abstract: A series of starting tests was conducted on a turbocharged diesel engine to investigate combustion instability for various coolant temperatures, ranging from 20 to 80°C, and fuel blends (neat diesel, blend of diesel with ...
Comparative Evaluation of Two Straight Vegetable Oils and Their Methyl Ester Biodiesels as Fuel Extenders in HDDI Diesel Engines: Performance and Emissions
Publisher: American Society of Civil Engineers
Abstract: The present work evaluates the effects of using blends of diesel fuel with two (straight) vegetable oils, viz sunflower and cottonseed, and their corresponding methyl ester biodiesels in proportions of 10% and 20% (by ...
Combustion and Emissions in an HSDI Engine Running on Diesel or Vegetable Oil Base Fuel with n-Butanol or Diethyl Ether As a Fuel Extender
