Paddy is the most important agricultural crop product in Bangladesh since it is widely used in daily life as a main meal intake. Currently, traditional manual harvesting process is widely used to harvest paddy grains in Bangladesh. However, manual harvesting is laborious, time-consuming, and...

HeavyEq is an Indonesian company that remanufactures diesel engines for the mining industry. The company experiences delays in the remanufacturing process that lead to a sales backlog. The main purpose of this paper is to identify the root cause of, and propose a solution to, the problem. A...

Most of the current zero-dimensional (0D) predictive combustion models for diesel engines are based on their simple artificial assumptions rather than actual diesel spray processes, resulting in poor prediction accuracy. Conventional multi-zone models have good prediction performance but a long...

In this study, borax decahydrate as a fuel additive was studied in a diesel single-cylinder engine. Borax decahydrate was dissolved in 500 ml of methanol, 5 gr, 15 g and 25 g, and methanol was added 10% to diesel fuel. To be 90% Diesel + 10% Methanol (D90M10) 90% Diesel 10% Methanol + 1 g Borax...

We determine the environmental benefit of using electric buses rather than diesel or CNG for urban transit. For diesel and CNG we calculate air pollution damages by combining emission rates with damage valuations from the AP3 integrated assessment model and the social cost of carbon. For...

Cold start is one of the most problematic combustion phases for diesel engines. During this phase, a large proportion of pollutants are produced within the cylinder due to misfiring and incomplete combustion due to the low engine temperatures. Furthermore, exhaust after-treatment devices work...

Diesel Powered engines are predominately used in transport and power generators. Due to rapid depletion of fossils fuels like diesel, there is need to find alternate resources for as a fuel for transport and power sector. The use of third generation fuels like algae seems to be a promising...

Biodiesel is one of the renewable fuels which is similar to diesel fuel. Biodiesel fuel has more oxygen than diesel fuel and this leads to better combustion and thereby, decreases PM, CO, and UHC emissions. On the other hand, biodiesel has a higher viscosity and density than diesel fuel which...

Due to the depletion of petroleum products and fatal emissions from the tailpipe of diesel engines it has become a need to seek for the alternative of petroleum products for long-term use. Currently, researchers and experts have come to the conclusion that biodiesel along with higher alcohols...

This paper uses the 2015 Volkswagen emissions scandal as a natural experiment to provide causal evidence that group reputation externalities matter for firms. We find that the Volkswagen scandal reduced the U.S. sales of the other German auto manufacturers—BMW, Mercedes- Benz, and Smart—by...

This paper uses the 2015 Volkswagen emissions scandal as a natural experiment to provide evidence that collective reputation externalities matter for firms. We find that the Volkswagen scandal reduced the U.S. sales of the other German auto manufacturers—BMW, Mercedes-Benz, and Smart—by...

This paper uses the 2015 Volkswagen emissions scandal as a natural experiment to provide evidence that collective reputation externalities matter for firms. We find that the Volkswagen scandal reduced the U.S. sales of the other German auto manufacturers--BMW, Mercedes-Benz, and Smart--by about...

Delving into the current chronicles of research findings, explorations of biodiesel production and utilization in diesel engines have been at the forefront of sustainable and creative energy discovery. Far beyond the problems of energy crises, renewable biodiesel offers unlimited solutions to...

In Germany the Volkswagen Diesel scandal is originally a market failure because the harm from vehicle emissions to public health and to the environment is neither internalized by car producers nor by car drivers. This market failure is neither corrected by public regulation nor by civil...

Die Diesel-Technologie und die mit ihrer Nutzung verbundenen Belastungen durch lokale und globale Schadstoffemissionen stehen seit längerem im Fokus der umweltpolitischen Diskussion. Mittlerweile sind sogar Fahrverbote für Diesel-Pkw nicht mehr ausgeschlossen. Allerdings sind in der...

This paper uses the 2015 Volkswagen emissions scandal as a natural experiment to provide causal evidence that group reputation externalities matter for firms. Our estimates show statistically and economically significant declines in the U.S. sales and stock returns of, as well as public...

The Volkswagen diesel emissions scandal of 2015 not only pushed that company’s stock and retail sales into freefall, but also raised serious questions about the efficacy of existing regulatory controls. The same furtive actions taken by Volkswagen had been taken nearly twenty years earlier by...

"This book provides research on technical and environmental enhancements to the emission and combustion characteristics of diesel engines. While highlighting topics such as biodiesel emulsions, nanoparticle additives, and mathematical modeling, this book explores the potential additives that...

Rape-seed biodiesel is an interesting option to address the problem of decreasing availability of conventional fossil fuels, as well as to reduce the CO₂ emissions of internal combustion engines. The present paper describes an experimental campaign carried out on a current production 4-cylinder,...

Volkswagen is one of the leading car manufacturers in the world. Our article talks about the diesel emission scandal of Volkswagen Group and actions taken by the regulators of numerous countries.
