Kefid · Abstract: This paper provides a comparative assessment of three economic optimal control strategies, aimed at minimizing the fuel consumption of heavy-duty trucks in a highway environment, under a representative lead vehicle model informed by traffic data. These strategies fuse a global, off-line dynamic programming (DP) optimization with online model predictive …
Kefid · Vehicle Energy Consumption calculation TOol - VECTO. VECTO is the new simulation tool that has been developed by the European Commission and shall be used for determining CO 2 emissions and Fuel Consumption from Heavy Duty Vehicles (trucks, buses and coaches) with a Gross Vehicle Weight above 3500kg. From 1 January 2019 the tool will be
As part of a parallel research program, UC Riverside has developed a Mobile Emissions Research Laboratory (MERL) that can be attached to a number of heavy duty rigs to measure instantaneous (i.e., modal) emissions and fuel consumption in-situ. Using MERL, a variety of trucks were extensively tested under a wide range of operating conditions.
Kefid · Commercial medium- and heavy-duty truck fuel efficiency technology study – Report #2. MYNHTSA's fuel consumption standards are voluntary in model years 2014 and 2015, becoming mandatory with model year 2016 for most regulatory to improve long haul truck engine fuel consumption by 5% without 2-waste heat recovery a
These emission factors and fuel consumption rates are for gasoline-fueled passenger cars and light-duty trucks only. Diesel cars represent less than 0.5 percent of all cars on the road in the United States as of 2005, and diesel light trucks represent less than 2 percent of all light-duty trucks on the road.
Fuel consumption model for heavy duty diesel trucks: Model
Kefid · Keywords: medium-duty, heavy-duty, powertrain, energy consumption, simulation 1 Introduction Many countries are establishing fuel economy standards for medium duty and heavy duty (MD/HD) trucks as part of programs to reduce greenhouse gas emissions. This paper is concerned with projecting the fuel
Kefid · 1. Support FCTO medium & heavy duty target settings – Develop models for fuel cell electric trucks (FCETs) that would meet or exceed the performance of present and future diesel powered trucks – Compare energy consumption of FCETs against best in class diesel powered class 8 sleeper trucks
Kefid · Unlike light-duty fuel economy standards, which mainly affect gasoline consumption, standards for medium- and heavy-duty vehicles will primarily affect diesel fuel consumption. As such, diesel consumption by medium- and heavy-duty vehicles in the Phase 2 Standards case is 18% lower (0.5 million boe/d) in 2040 compared to the Reference case.
Kefid · Fuel Consumption Standards for Heavy Duty Vehicles. Winston Harrington. Date. Oct. 17, 2011. The Environmental Protection Agency and the National Highway Traffic Safety Administration have recently introduced regulations for fuel economy and carbon dioxide emissions from heavy duty vehicles. This marks the first time the federal government has
Kefid · idle fuel consumption from a sample of 19 medium heavy-duty diesel and gasoline vehicles with model years ranging from 1974 to 2001. These data are particularly relevant because, according to the 2002 U.S. Census Bureau, 75% of the medium-duty trucks operating in the United States were model year 1997 or older. No new data were found, but this
Kefid · Heavy-duty trucks contribute approximately 20% of fuel consumption in the United States of America (USA). The fuel economy of heavy-duty vehicles (HDV) is affected by several real-world parameters like road parameters, driver behavior, weather conditions, and vehicle parameters, etc. Although modern vehicles comply with emissions regulations, potential …
Kefid · An instantaneous energy consumption model is developed for diesel heavy duty trucks. The model does not produce a bang-bang control system. A convex fuel consumption model captures grade and truck weight impacts on fuel consumption. The model estimates are demonstrated to be consistent with the field measurements.
Abstract. A simple, efficient, and realistic fuel consumption model is essential to support the development of effective eco-freight strategies, including eco-routing and eco-driving systems. The majority of the existing heavy duty truck (HDT) fuel consumption models, however, would recommend that drivers accelerate at full throttle or brake at
2 · Download the 2021 Fuel Consumption Guide [PDF – 2.63 MB] The 2021 Fuel Consumption Guide gives information about the fuel consumption of 2021 model year light-duty vehicles. You can use this information to compare vehicles as you shop for the most fuel-efficient vehicle that meets your everyday needs. Remember as you shop that fuel is an

Overview. 2 and fuel consumption reductions vary by vehicle type and range from 6–23% compared to a model year 2010 baseline. Phase 2 standards are applicable for 2018–2027 and are estimated to reduce CO 2 and fuel consumption 16% for heavy-duty pickup trucks and vans, 16%–19% for vocational vehicles, and up to 30% for tractor-trailers.
