GUIDE TO MANIFOLD ABSOLUTE PRESSURE TRANSDUCER REPRESENTATIVE TEST METHOD

1981-06-01

CURRENT

J1346_198106

This guide is intended to cover test procedures applicable to MAP transducers; it is also applicable to transducers such as Barometric (Ambient) Absolute Pressure transducers, Manifold Vacuum transducers, and similar pressure transducers used in automotive systems. Although oriented towards active devices (those using internal signal conditioning), it can be applied to passive devices with minor modifications.

Performance Engine Building Recommended Practices

2019-10-03

CURRENT

J2379_201910

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.

Validation of Compressibility Test Systems for Friction Materials

2021-01-13

CURRENT

J3079/1_202101

This SAE Recommended Practice (RP) applies to the validation process for test systems used to measure deflection (compressibility, creep, or swell and growth) of friction materials and friction material assemblies. The materials or assemblies can fit passenger cars, light trucks, and commercial vehicles equipped with hydraulic or air brake systems, using disc or drum brakes.

Low-preload Deflection Measurement for Brake Pads, Noise Shims, and Brake Pad Assemblies

2016-07-14

CURRENT

J3079/2_201607

This SAE Standard specifies a method for measuring the deflection of friction materials, noise insulators, and disc brake pad assemblies to be used in road vehicles with a Gross Vehicle Weight Rating below 4336 kg. This part of the SAE J3079 includes the test for deflection and creep at various pressures under ambient temperature conditions. This SAE test method differs from SAE J2468 and ISO 6310 in the preload and maximum load applied to the test sample when deflection is measured. It also introduces additional measurements such as for deflection offset, hysteresis, and creep.

Cleanliness Rating of Steels by the Magnetic Particle Method

2018-01-09

CURRENT

J421_201801

This SAE Recommended Practice provides a rating procedure for the cleanliness rating of steels by the magnetic particle method. The procedure is based on counting the number of indications (frequency) and employs a weighted value to obtain a severity factor. The method outlined is similar to that described in SAE Aerospace Material Specification AMS 2301.

CURRENT

J3231_202206

This SAE Recommend Practice specifies a method for measuring the deflection of friction materials and disc brake pad assemblies in a manner more consistent with classical material compressive strain testing. This SAE test method differs from SAE J2468 in the preload and maximum load applied to the test sample when deflection is measured. It adopts the material applied stress levels found in ISO 6310 (0.5 to 8.0 MPa) using a 25 mm diameter flat plunger.

Internal Combustion Engines--Piston Rings Coil Spring Loaded Oil Control Rings

2008-06-30

CURRENT

J2003_200806

This SAE Standard is equivalent to ISO Standard 6626. Differences, where they exist, are shown in the appendix with associated rationale. This document specifies the essential dimensions of piston ring types DSF-C, DSF-CNP, SSF, GSF, DSF, DSF-NG, and SSF-L coil spring loaded oil control rings. For the cast iron part the recommended material is class 10 according to SAE J1590. For special applications material classes 20 to 50 may be used. Variation in face design and spring groove from these may be used, as recommended by individual manufacturers, in plain or chromed versions. The tangential forces of coil spring loaded oil control rings can be varied over a wide range. Explanations and recommendations are given in Section 6. The normal range for axial width of coil spring loaded oil control rings (3 to 8 mm inclusive) is divided into 0.5 or 1.0 mm steps.

J2914_201111

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 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.

This document describes the various scuffing failure modes of the power cylinder system in an internal combustion engine. The causes and preventative measures for each failure mode are discussed. It should be noted that many remedies for scuff can lead to NVH (noise vibration and harshness) issues. However, NVH is not considered in this document.
