Improving Fuel Efficiency with Engine Oils

2019-05-06
Improving vehicular fuel efficiency is of paramount importance to the global economy. Governmental regulations, climate change and associated health concerns, as well as the drive towards energy independence, have created a technical need to achieve greater fuel efficiency. While vehicle manufacturers are focusing efforts on improved combustion strategies, smaller displacement engines, weight reduction, low friction surfaces, etc., the research involved in developing fuel efficient engine oils has been less publicized.

Measurement of Passenger Compartment Refrigerant Concentrations Under System Refrigerant Leakage Conditions

2011-02-04
CURRENT
J2772_201102
This Standard is restricted to refrigeration circuits that provide air-conditioning for the passenger compartments of passenger and commercial vehicles. This Standard includes analytical and physical test procedures to evaluate concentration inside the passenger compartment. In the early phases of vehicle evaluation, usage of the analytical approach may be sufficient without performing physical tests. The physical test procedure involves releasing refrigerant from an external source to a location adjacent to the evaporator core (inside the HVAC-Module). An apparatus is used to provide a repeatable, calibrated leak rate. If the system has multiple evaporators, leakage could be simulated at any of the evaporator locations. This standard gives detail information on the techniques for measuring R-744 [CO2] and R-1234yf [HFO-1234yf], but the general techniques described here can be used for other refrigerants as well.

Refrigerant 12 Automotive Air-Conditioning Hose

2015-04-21
CURRENT
J51_201504
This SAE Standard covers reinforced hose, or hose assemblies, intended for conducting liquid and gaseous dichlorodifluoromethane (refrigerant 12) in automotive air-conditioning systems. The hose shall be designed to minimize permeation of refrigerant 12 and contamination of the system and to be serviceable over a temperature range of −30 to 120 °C (−22 to 248 °F). Specific construction details are to be agreed upon between user and supplier.1 NOTE—R12 refrigerant has been placed on a banned substance list due to its ozone depletion characteristics. SAE J51 specification will be phased out as new automotive A/C systems are using R134a. SAE J2064 is the Standard for refrigerant 134a hose. For refrigerant 134a use, refer to SAE J2064.

Push-On Hose and Mating Hose Fittings

2014-06-06
CURRENT
J2552_201406
SAE J2552 provides limited, dimensional and general performance requirements for low pressure, field attachable, push-on hose and their mating hose fittings. The intended application is for fluid and pneumatic power used with petroleum base hydraulic fluids, lube oils, water glycols and air, within the temperature ranges listed in Table 1. The maximum working pressure is 1.7 MPa (see Table 2). For air applications the maximum working pressure is at 0.7 MPa. Hose and hose fittings are manufactured within certain dimensions with tolerance ranges in order to provide the proper gripping and sealing. SAE J2552 hose from one manufacturer may not be compatible with SAE J2552 hose fittings supplied by another manufacturer. It is the responsibility of the fabricator to always follow the manufacturers’ instructions for proper preparation and fabrication of hose assemblies.

Sleeve Type Half Bearings

2011-06-10
CURRENT
J506_201106
This SAE Standard defines the normal dimensions, dimensioning practice, tolerances, specialized measurement techniques, and glossary of terms for bearing inserts commonly used in reciprocating machinery. The standard sizes cover a range which permits a designer to employ, in proper proportion, the durability and lubrication requirements of each application, while utilizing the forming and machining practices common in manufacture of sleeve type half bearings. Not included are considerations of hydrodynamic lubrication analysis or mechanical stress factors of associated machine structural parts which determine the nominal sizes to be used, selection of bearing material as related to load carrying capacity, and economics of manufacture. For information concerning materials, see SAE J459 and SAE J460. These suggested sizes provide guidelines which may result in minimal costs of tooling but do not necessarily represent items which can be ordered from stock.
