Heavy-Duty Diesel Vehicle Fuel Consumption Modeling Based on Road Load and Power Train Parameters

Abstract

The EPA is developing a new generation emissions inventory model, MOVES (Motor Vehicle Emissions Simulator). The first version of the model outputs fuel consumption based on available modal data. However, due to the limited heavy-duty vehicle data, MOVES rates need to be supplemented with rates determined with the Physical Emission Rate Estimator (PERE). PERE combines vehicle tractive power together with vehicle powertrain parameters specific to the class of vehicle; the vehicle weight, shape, engine type, and transmission. Analysis of in-use data for heavy-duty diesel tractortrailer vehicles, city transit diesel buses, and dynamometer non-road diesel engines has enabled a determination of diesel engine efficiency and friction and transmission shift schedules for these engines and vehicles. These model parameters and a comparison of the model results to measured fuel consumption and CO 2 emissions are presented.

Sensitivity analysis of biodiesel blends on Benzo[a]pyrene and main emissions using MOVES: A case study in Temuco, Chile

“…One of the best simulation programs with the largest state-of-the-art options for doing mobile sources inventory is the program MOVES implemented by the Office of Transportation and Air Quality in the United States, pertaining to the U.S. Environmental Protection Agency (Giannelli et al, 2005;Gurjar et al, 2010;Guldner, 2013). This model is capable of estimating emissions for the aforementioned pollutants, as well as an ample range of substances in multiple scales of analysis, permitting as well the free use of the software (EPA, 2012a(EPA, , 2012b.…”

Modeling Relationship between Truck Fuel Consumption and Driving Behavior Using Data from Internet of Vehicles

“…Chen et al (2015) used Next Generation SIMulation data (NGSIM) and CMEM to analyze fuel consumption/emissions aggregated at both lane and link levels. Some researchers also carried out research with respect to the impact of driv-ing behavior on fuel consumption and emissions (Ericsson, 2001;Giannelli et al, 2005;Wu et al, 2015;Walnum and Simonsen, 2015).…”

Investigating the Potential of Waste Heat Recovery as a Pathway for Heavy-Duty Exhaust Aftertreatment Thermal Management

“…The input energy carried in by the intake air is calculated using the mass flow rate of the intake air, ̇ and the enthalpy of air at respective intake temperature. The rate of fuel energy supplied to the engine is calculated based on the mass flow rate of the fuel, ̇, and energy content of a diesel fuel provided by the lower heating value (LHV) taken as 43MJ/kg (Giannelli et al, 2005).…”
