The purpose of this SAE Standard is to provide a standardized test procedure for measuring the fuel consumption of spark ignited engines in the range of 225-999cc used in the consumer and commercial turf industry. The load points and associated fuel consumption rates will be measured as the engine operates on the engine speed governor, reflecting how the user will operate the equipment. The fuel consumption calculated in gallons of useage per hour will be derived from a specified engine speed and load map to be communicated universally to end users.

This SAE Standard specifies: a test method for assessing the lubricating property of diesel fuels including those which may contain a lubricity enhancing additive, and the performance criteria necessary to ensure reliable operation of diesel fuel injection equipment with respect to fuel lubrication of such equipment. It applies to fuel used in diesel engines.

This SAE Recommended Practice applies to the function of building reciprocating spark-ignition engines which are used in conjunction with standard and high-performance ancillary components in applications intended to achieve a minimum of 1 hp/in3. This document does not apply to rebuilt engines which may only be partially repaired with little or no machining, nor does it apply to second-hand or used engines.

This SAE Standard specifies the dimensional requirements for the assembly of high-pressure pipe connections for compression-ignition (diesel) engine fuel injection equipment. It applies to 60 degrees female cones with external threaded connectors types 1 and 2 (see Figures 1, 2, and 3), and to the internal threaded tube nuts and male cone type end assembly (see Figure 4) of high-pressure pipe connections for tubes with diameters up to 12 mm inclusive.

This SAE Recommended Practice covers power transfer units (PTUs) used in passenger car and sport utility vehicles to support all wheel drive (AWD) operation. PTUs are typically full-time use geared devices (see 3.1). Some PTUs have additional features such as part-time on-demand capability via electronically actuated disconnect features, and other configurations are possible.

This SAE Standard specifies the dimensional requirements necessary for the interchangeability of tapered shaft ends and hubs for fuel injection pumps of diesel engines.

This SAE Standard specifies the dimensional requirements necessary for the interchangeability of tapered shaft ends and hubs for fuel injection pumps of diesel engines.

The fuel injection pump is intended to validate the accuracy of calibrating nozzle and holder assemblies for applications using 0.4 - 0.8 mm diameter orifice plates and to assist in identifying problems in fuel injection pump test stands. This SAE Recommended Practice is divided into two parts: Part I—Design, Description and Specifications of the Fuel Injection Pump; and Part II—Test Procedures for Using the Fuel Injection Pump.

The correct setting and adjustment of fuel injection pumps requires standardized testing conditions. This SAE Standard summarizes the design and operating parameters for test benches so that, using certain information supplied by the pump manufacturer, the pump test schedule, and certain information supplied by the test bench manufacturer, it can be determined whether a particular test bench is suitable for driving a particular injection pump. This document is in most cases a summary of the ISO Standard 4008, Parts 1, 2, and 3 and is intended to provide its critical aspects. Standard ISO 4008 should be referred to for more details.

This SAE recommended practice is intended for use in testing and evaluating the performance of light-duty automotive electric engine cooling fan assemblies. These Electric Cooling Fan (ECF) assemblies are purchased by light-duty truck and passenger car OEMs from suppliers. They are purchased as complete assemblies, consisting mainly of the fan(s), motor(s), and shroud (see Figure 1); this Recommended Practice will only consider such complete assemblies. Some purchased assemblies using brush-type motors may also include digital control devices such as power resistors or pulse width modulation (PWM) electronics or local interconnect network (LIN) for speed control. In the case of brushless motor technology, the controller is an integral part of the motor where it also performs the commutation process electronically. The performance measurement would include fan output in terms of airflow and pressure, and fan input electric power in terms of voltage and current.

This procedure incorporates test cycles that produce relative fuel economy data relating to long haul, short haul, and. local driving patterns, or any combination of these and to those components developed to improve fuel economy for these patterns. The tests conducted on a specific vehicle are to reflect that vehicle’s general mode of operation. The procedure is intended to be used under controlled, warmed-up conditions on a test tract or on suitable roads. A minimum of two vehicles running simultaneously is required. Test condition recommendations are provided for undertaking this engineering test. If it is necessary to conduct a test outside of these test conditions, the purpose of the test and the variant conditions should be recorded and noted whenever the results are reported.

This recommended practice applies to the laboratory measurement of the rolling resistance of pneumatic tires designed primarily for use on trucks and buses in normal highway service, as defined by the Tire and Rim Association, Inc. (TRA); it does not include light truck tires (designated LT). The procedure applies only to straight, free-rolling tires under steady-state operation and includes the following three basic methods:
