Predicting Tractor Fuel Consumption
Reports from the Nebraska Tractor Test Laboratory (NTTL) show improved fuel efficiency during the past 20 years. A 4.8% decrease in average annual specific volumetric fuel consumption for the data used in theASAE Standards was shown. Using fuel consumption and power data from the NTTL reports, new equations for fuel consumption were established that predict fuel consumption for diesel engines d...
متن کاملFuel Consumption and Operational Performance
Reducing fuel consumption is a major goal for the aviation community due to environmental concern and fuel price uncertainty. The Federal Aviation Administration (FAA) is currently developing and implementing Air Traffic Management (ATM) technologies to ensure reliable operational performance that is robust to delays caused by congestion and weather. These technologies will reduce planned and u...
متن کاملStriving for Lower Fuel Consumption
and a contra rotating propeller behind it mounted on a pulling mechanical thruster. The machinery has been confi gured to keep the initial cost low by avoiding expensive electric pods and drives, and by going to a simple mechanical drive of the forward propeller using a large bore main engine. A novel machinery and cargo ramp arrangement has been developed to facilitate also very large main eng...
متن کاملAirline Fuel Savings Estimation Based on Segmented Fuel Consumption Profiles
Fuel conservation programs are instruments used by airlines to improve operational efficiency and trim fuel related costs. Identifying fuel savings to accurately manage these programs has always been an issue due to the operation volatility and lack of reliable data. Advanced data management systems were developed to support these programs, but having means to identify fuel savings is still com...
متن کاملAlcohol consumption and domestic violence against mothers.
BACKGROUND A recent high-profile murder case and the passage of the Unborn Victims of Violence Act have focused policymakers' attention on domestic violence against pregnant women and new mothers. The link between men's alcohol consumption and spousal abuse has led some to suggest that more stringent alcohol regulations could ameliorate domestic violence. AIM OF STUDY (i) To examine the corre...
