Heat Augmentation Prevention Shield on Tractor Horizontal Exhaust Pipe for Field Fire Safety Compliance
2020-09-25
2020-28-0370
Off highways vehicles especially tractors are prone to operate on fields where tractors are exposed to dry crops, chaffs (the husks of corn or other seed separated by winnowing or threshing) and particles which can catch fire easily when it is exposed to surface/skin temperature of more than 200 degree Celsius. It will be a basic projection that tractor will be having vertical exhaust tube at a height but there are certain tractors and applications where exhaust pipe must be below certain height, and which will be close to the ground. In these scenarios the skin temperature of exposed exhaust tail pipe part must be within a limit and that must be within the existing design. Break firing point of chaffs and husk also experimented at different moisture level. Several options are being verified on different heat flow and geometry changes, additional air entry jet nozzle with double pipe arrangement.

Trends in Hydraulic Hose and Assemblies
1991-09-01
911884
Hoses and assembies used in hydraulic applications are constantly being required to do more and more. The hydrostatic drives are becoming more sensitive to dirt and contamination. In addition, new hydraulic fluids are now being introduced that are more environmentally, safe. As a result, care must be taken in choosing the materials used and the processes of manufacturing in order to ensure that the assemblies provide long life and will not contribute to system failures.

Testing and Prediction of Material Compatibility of Biofuel Candidates with Elastomeric Materials
2015-11-01
2015-01-9075
In this paper compatibility studies of biofuel candidates and similar liquids with the elastomeric materials nitrile butadiene rubber and fluoroelastomer are presented. The results gained with defined reference elastomers are compared to results gained with the materials used in the technical application. For this purpose test specimens are prepared from fuel hoses and the material used for shaft seals of fuel pumps. The experimental results are subsequently used to evaluate prediction approaches based on the HSP- and QSPR-method. Finally a comparison of these two approaches is given.

Oil Change System for Quick Service of Off-Road Self-Propelled Work Machines
2007-03-20
HISTORICAL
J1069_200703
This recommended practice deals with sizes, design considerations, and practices related to evacuating and refilling by positive means any oil comportment. This practice may also be applicable to other fluid compartments and is to supplement rather than eliminate the drain plug. (Ref. ISO TC 131/4/N27)

CURRENT
J1350_201111
This information report covers fuel fired pre-heaters which burn gasoline, diesel, or propane fuels. This type of heater must be used in remote areas where 110/220 V, 60 Hz electric power is not available, and is recommended anywhere an on-board self contained system is required. The guidelines in this report are applicable, but not limited to, fuel burning heater installations on the off-road self-propelled work machines described in SAE J1116.

CURRENT
J1394_201306
This SAE Standard covers the minimum requirements for metric sizes of nonmetallic tubing as manufactured for use in air brake systems. Nonreinforced products are designated type A and reinforced products type B. It is not intended to cover tubing for any portion of the system that operates below -40 °C (-40 °F), above +93 °C (+200 °F), above a maximum working gage pressure of 1.0 MPa (150 psi), or in an area subject to attack by battery acid. This tubing is intended for use in the brake system for connections that maintain a basically fixed relationship between components during vehicle operation.
