The testing technique outlined in this SAE Recommended Practice was developed as part of an overall program for testing and evaluating fuel consumption of heavy-duty trucks and buses. The technique outlined in this recommended practice provides a general description of the type of equipment and facility which is necessary to determine the power consumption of these engine-driven components.It is recommended that the specific operating condition suggested throughout the test be carefully reviewed on the basis of actual data obtained on the specific vehicle operation and the fan.Because of the variation in size, shape, configuration, and mountings available in cooling fans, specific test devices have not been included.

Requirements For Engine Cooling System Filling Deaeration And Drawdown Tests written by Cooling Systems Standards Committee and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1989 with categories.
This SAE Information Report is applicable to all engine cooling systems used in heavy-duty vehicles, industrial applications, and automotive applications The purpose of this document is to list the requirements which are in general use for filling, deaeration, and drawdown of engine cooling systems for heavy-duty, industrial and automotive applications. Due to the differences in heavy duty and automotive cooling systems, they are dealt with in separate sections of this report. In the case of heavy duty, these procedures apply to both the main jacket water pump and separate circuit water pumps. The material presented in this document is for information purposes only, and does not constitute a SAE Standard.

The past 10 to 15 years have seen a dramatic change in heavy duty coolants and cooling system maintenance practices. Controversy exists about the relative merits of newer organic acid (OAT) coolants and more conventional products, especially in the area of thermal stability. Coolant life has been extended from two years/240 K miles to at least five years/600 K miles. It is not uncommon for the same charge of coolant to remain in the cooling system until engine rebuild. Further, there has been an equally significant increase in the coolant service intervals. Reinhibition of the coolant was once tied to the oil change interval at 15 to 25 K miles. Now this additive addition has been extended in many cases to one year/150 K miles to two years/300 K miles. • Along with these dramatic increases in coolant life and service interval, strategies to reduce exhaust emissions such as EGR have increased and will continue to increase coolant temperatures. Sorting out coolant stability issues in the field is both expensive and time consuming. Further, it is very difficult to control a field test so as to obtain reliable data. In this environment, a bench test method that can quickly simulate high temperature, severe field service conditions is of vital importance. This paper compares four bench test methods as far as their ability to sort out thermal stability issues based on results from five coolants representing different additive packages and glycol qualities.

Annotation Emerging from a November 1991 symposium in Scottsdale, Arizona, 19 papers report on advances in developing, testing, and applying engine cooling fluids for automobiles and heavy duty engines. Among the topics are carboxylic acids as corrosion inhibitors in engine coolant, phosphate-molybdate supplements to heavy duty diesel engines, the toxicity and disposal of engine coolants, and the characterization of used engine coolant by statistical analysis.

Three levels of fan structural analysis are included in this practice: (a) Initial Structural Integrity (b) in-vehicle Testing (c) Durability 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 that may be used depending on type of fan, equipment availability, and end objective.Each of the previous levels builds 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 heavy-duty trucks, construction equipment, industrial, and agricultural equipment. It does not necessarily include passenger cars and light trucks.The purpose of this document is to identify the general methodology for the structural analysis of engine cooling fans, and to provide expanded information on subset practices within the general methodology, such that a user of this practice can adapt specific subsets related to a vehicle class.
