Off-Road Self-Propelled Work Machines Operator enclosure environment Part 4:Heating, ventilating and air conditioning (HVAC) test method and performance

2014-09-16
WIP
J3078/4
J3078/4 specifies a uniform test method for measuring the contribution to operator environmental temperature provided by a heating, ventilating and air conditioning system operating in a specific ambient environment. The method might not determine the complete climatic environment of the operator since this is also affected by heat load from sources other than those on the machine, for example solar heating. J3708/6 is to be used in conjunction with J3078/4 to determine more accurately the complete heat loading on the operator enclosure. Minimum performance levels for the machine’s operator enclosure heating, ventilating and air conditioning systems are established in J3708/4.

Auxiliary Power Unit Electrical Interface Requirements for Class Eight Trucks

2010-07-06
HISTORICAL
J2891_201007
This SAE Recommended Practice covers the design and application of a 120 VAC single phase engine based auxiliary power unit or GENSET. This document is intended to provide design direction for the single phase nominal 120 VAC as it interfaces within the truck architecture providing power to truck sleeper cab hotel loads so that they may operate with the main propulsion engine turned off.
