Measuring Energy Consumption, Fuel Economy and Emissions of Conventional and Hybrid Medium/Heavy-Duty Vehicles using a Powertrain Dynamometer

2017-06-22
WIP
J2711/2
This SAE Recommended Practice was established to provide an accurate, uniform and reproducible procedure for simulating use of MD/HD conventional vehicles and hybrid-electric vehicles (HEVs), as well as plug-in hybrid-electric vehicles (PHEVs) and battery electric vehicles (BEVs) on powertrain dynamometers for the purpose of measuring emissions and fuel economy. This document does not specify which emissions constituents to measure (e.g., HC, CO, NOx, PM, CO2), as that decision will depend on the objectives of the tester. While the main focus of this procedure is for calculating fuel and energy consumption, it is anticipated that emissions may also be recorded during execution of this procedure. It should be noted that most MD/HD powertrains addressed in this document would be powered by engines that are certified separately for emissions. The engine certification procedure appears in the Code of Federal Regulations, Title 40-§86 and §1065.

This document defines a physical layer having a higher bandwidth capacity than the classic physical layers defined for SAE J1939-14 by using flexible data rates. CAN controllers are now available which support the Flexible Data Rate Frame Format as defined in ISO 11898-1:2015. These controllers and compatible high speed transceivers are required for use on SAE J1939-17 networks. This SAE Recommended Practice is intended for light- and heavy-duty vehicles on- or off-road as well as appropriate stationary applications which use vehicle derived components (e.g., generator sets).

Diesel Fuels

2017-06-07
CURRENT
J313_201706
Automotive and locomotive diesel fuels, in general, are derived from petroleum refinery products which are commonly referred to as middle distillates. Middle distillates represent products which have a higher boiling range than gasoline and are obtained from fractional distillation of the crude oil or from streams from other refining processes. Finished diesel fuels represent blends of middle distillates and may contain other blending components of substantially non-petroleum origin, such as biodiesel fuel blend stock, and/or middle distillates from non-traditional refining processes, such as gas-to-liquid processes. The properties of commercial distillate diesel fuels depend on the refinery practices employed and the nature of the crude oils from which they are derived. Thus, they may differ both with and within the region in which they are manufactured. Such fuels generally boil, at atmospheric pressure, over a range between 130 °C and 400 °C (approximately 270 °F to 750 °F).
