In this paper, we use an agency theory framework to address the relative efficiency of a duty to creditors, a duty to refrain from wrongful trading, or contractual devices.
In late October, the EPA and U.S. Department of Transportation released the first national standards to reduce greenhouse gas emissions from and improve fuel efficiency of heavy-duty vehicles including combination tractors, heavy-duty pickups and vans, and vocational vehicles (such as delivery trucks, dump trucks and buses).
In order to investigate the effects of altitude on the brake thermal efficiency of heavy-duty diesel engines, an experimental study on a heavy-duty diesel engine operating at various altitudes was conducted.
Thermal barrier coatings (TBCs) may improve the fuel efficiency of heavy-duty diesel engines by reducing heat losses.
A theoretical study is conducted to investigate the potential improvement of the overall efficiency of a heavy-duty truck diesel engine equipped with a Rankine bottoming cycle for recovering heat from the exhaust gas.
The new vehicle standards will eliminate billions of tons of carbon dioxide emissions and double the fuel efficiency of the American light-duty transportation fleet over the next decade.
"While we were working to improve the efficiency of cars and light-duty trucks, something interesting happened," he said in a statement.
Additionally, PepsiCo has joined other leading companies in calling for strong standards to increase the fuel efficiency of heavy- and medium-duty trucks.
The observed overall duty cycle efficiency of the power-plant was from 28%to40%0% and peak-power demand, such as during acceleration, was provided by the battery-pack, while average power during the duty cycle was met by the fuel cell stack, as designed.
He instilled a sense of duty, efficiency and professionalism in the Indian Army, and he taught officers to stand up to political masters and bureaucratic interference.
The best recovery efficiency is about 2%, with an average thermoelectric material efficiency of approximately 4.4%, for the light-duty vehicle.
