Thermal Flow Control Valve Nomenclature and Application

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J3142_201811
  • Current
Published 2018-11-02 by SAE International in United States
The purpose of this SAE Information Report is to define common industry terminology and nomenclature relative to thermal flow control valves and to describe common thermal flow control valve applications in automotive, highway truck, mobile construction equipment, and industrial applications. This document is primarily directed at internal combustion engine or electric powered applications and the downstream systems to which power is provided, such as transmissions, hydraulics, air compression, etc. The information contained herein does not constitute an SAE Standard.

Coolants for Internal Combustion Engines

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J814_201803
  • Current
Published 2018-03-29 by SAE International in United States
This SAE Information Report is a source of information concerning the basic properties of engine coolants which are satisfactory for use in internal combustion engines. Engine coolant concentrate (antifreeze) must provide adequate corrosion protection, lower the freezing point, and raise the boiling point of the engine coolant. For additional information on engine coolants see ASTM D3306 and ASTM D4985.

Heavy Duty Vehicle Cooling Test Code

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J1393_201712
  • Current
Published 2017-12-12 by SAE International in United States
The purpose of this SAE Recommended Practice is to establish a testing procedure to determine the performance capability of heavy duty vehicle cooling systems to meet Original Equipment Manufacturer or end user thermal specifications to ensure long term reliable vehilcle operations. The recommendations from the present document are intended for heavy-duty vehicles including, but is not limited to, on- and off-highway trucks, buses, cranes, drill rigs, construction, forestry and agricultural machines.

Test Method for Determining Power Consumption of Engine Cooling Fan Drive Systems

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J1342_201706
  • Current
Published 2017-06-26 by SAE International in United States
The techniques outlined in this SAE Recommended Practice were developed as part of an overall program for determining and evaluating fuel consumption of heavy-duty trucks and buses, but it is applicable to off highway vehicles as well. It is recommended that the specific operating conditions be carefully reviewed on the basis of actual installation data. Cooling requirements are affected by all heat exchangers that are cooled by the fan drive system. These may include radiators, condensers, charge air coolers, oil coolers, and others. Because of the variation in size, shape, configuration, and mountings available in cooling fans and fan drive systems, specific test devices have not been included. Using known power/speed relationships for a given fan, this procedure can be used to calculate the fan drive system’s power consumption for engine cooling systems using fixed ratio, viscous or speed modulating, and mechanical on/off fan drives including electronically activated fan drives. This power consumption may then be used in determining engine net power per SAE J1349. For fan power/speed relationships, refer to SAE J1339.

Engine Cooling Fan Structural Analysis

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J1390_201706
  • Current
Published 2017-06-01 by SAE International in United States
Three levels of fan structural analysis are included in this practice: a Initial Structural Integrity b In-vehicle Testing c Durability (Laboratory) Test Methods The Initial Structural Integrity section describes analytical and test methods used to predict potential resonance and, therefore, possible fatigue accumulation. The In-vehicle (or machine) section enumerates the general procedure used to conduct a fan strain gage test. Various considerations that may affect the outcome of strain gage data have been described for the user of this procedure to adapt/discard depending on the particular application. The Durability Test Methods section describes the detailed test procedures for a laboratory environment that may be used depending on type of fan, equipment availability, and end objective. The second and third levels build upon information derived from the previous level. Engineering judgment is required as to the applicability of each level to a different vehicle environment or a new fan design. This SAE Recommended Practice is applicable to any engine cooling fan application including medium and heavy-duty trucks, buses, construction equipment, industrial, and agricultural equipment.
