This document supersedes SAE J819 - Engine Cooling System Field Test. The purpose of this SAE Recommended Practice is to establish a testing procedure to determine the performance capability of engine cooling systems, including charge air coolers, on heavy-duty vehicles with liquid-cooled internal combustion engines. The definition of heavy vehicles for this document includes, but is not limited to, on- and off-highway trucks, cranes, drill rigs, construction, forestry and agricultural machines. Vehicles equipped with side or rear-mounted radiators may require an alternate procedure of a towing dynamometer because of peculiar aerodynamics. Testing is generally conducted to determine compliance with cooling criteria established by the engine manufacturer or the end product user to meet a desired engine reliability goal.

What's New at ConExpo/IFPE A preview of some of the new products and technologies that companies plan to showcase at this year's ConExpo-Con/Agg, which is co-located with the IFPE fluid-power event in Las Vegas from March 4-8. Injection strategies for improving emissions characteristics Premixed charge compression ignition reduces NOx and soot emissions, but requires the optimization of the injection timing and pressure, fuel mass in pilot injection, and EG R rate. Systems that talk together, are efficient together Design teams take a holistic view, linking engines, transmissions, hydraulics, and aftertreatment systems to boost efficiency and performance. Managing the deluge of data The model-based development (MBD) process has been a key enabler of technical advancement in the transportation industry; however, the MBD process leads to the generation of large volumes of data artifacts and work products.

Putting lightweighting to the test Material laws and orientation information are coupled in a single finite element analysis to predict the performance of the hybrid composite beam under a dynamic three point bending load. Screens, cameras provide new look in cabs Video inputs are another option showing up on displays that increasingly offer touch control. Big performance in small packages By regulating light-duty engine variable speed fans based on heat rejection demands and ambient temperature, consistent power savings over the entire operating spectrum can be achieved.

Virtual casting improves powertrain design As designers continue to look for ways to cut weight and increase performance, casting simulations are helping optimize designs through faster, more accurate predictions of the casting process used to create key components. Horse racing America's pony cars are a favorite of racers and fans alike, so racing them against each other is natural. SAE 2015 World Congress Preview Tech trends and exhibitor products are highlighted. Tech trends and exhibitor products are highlighted in this special section, which features an exclusive interview with Honda R&D America's Jim Keller. Replicating the racing experience Professional driving simulators can be successfully exploited to shorten the traditional design-prototype testing-production process relative to a new racecar.

Clearing the air Sensors, diagnostics and controls advance to help trap emissions. Bringing the heat on cooling technologies Electronic controls, variable-speed fans cool engines, heat aftertreatment systems. 3D printing machines can't be built fast enough In the additive manufacturing world, the costs of components are dropping, the technology is becoming more reliable and parts are fabricated faster, allowing industries beyond aerospace to adopt additive technologies, says Oak Ridge Lab's Ryan Dehoff.

An updated version of GE Aviation’s T901-GE-900 turboprop engine used in the AH-64 Apache attack and UH-60 Black Hawk utility helicopters successfully completed the preliminary design review for the U.S. Army’s Improved Turbine Engine Program.
