Laboratory Testing of Light-Duty Vehicle Electric Cooling Fan Assemblies for Airflow Performance

2024-10-02
CURRENT
J2867_202410
This SAE Recommended Practice is intended for use in testing and evaluating the performance of electric cooling fan (ECF) assemblies typically used for vehicle engine cooling. Conducted in a laboratory environment with intended heat exchangers, the performance measurement includes fan output in terms of airflow and pressure and fan motor input in terms of voltage and current. This information can be used to calculate the efficiency of the assembly, including aerodynamic efficiency of the fan and shroud, and electrical efficiency of the motor. The electric power consumption can be used to estimate electrical charging system sizing and fuel economy. The performance of a given fan assembly depends on the installation details of the application, including the effects of system resistance and geometries of the grill, heat exchangers, engine and other underhood components, and front end components.

Test Method for Measuring Performance of Engine Cooling Fans

2024-09-18
CURRENT
J1339_202409
This SAE Recommended Practice is intended for use in testing and evaluating the approximate performance of engine-driven cooling fans. This performance would include flow, pressure, and power. This flow and pressure information is used to estimate the engine cooling performance. This power consumption is used to estimate net engine power per SAE J1349. The procedure also provides a general description of equipment necessary to measure the approximate fan performance. The test conditions in the procedure generally will not match those of the installation for which cooling and fuel consumption information is desired. The performance of a given fan depends on the geometric details of the installation, including the shroud and its clearance. These details should be duplicated in the test setup if accurate performance measurement is expected.

This document provides an overview on how and why EGR coolers are utilized, defines commonly used nomenclature, discusses design issues and trade-offs, and identifies common failure modes. The reintroduction of selectively cooled exhaust gas into the combustion chamber is just one component of the emission control strategy for internal combustion (IC) engines, both diesel and gasoline, and is useful in reducing exhaust port emission of nitrogen oxides (NOx). Other means of reducing NOx exhaust port emissions are briefly mentioned, but beyond the scope of this document.

Test Method for Determining Power Consumption of Cooling Fan Drive Systems

2022-08-26
CURRENT
J1342_202208
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 cooling systems using the types of drives listed below. This power consumption may then be used in determining engine net power per SAE J1349.

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.
