“Evaluation of the Drift of vehicle Inspection/Maintenance Emission Analyzers in use- A California Case Study”

1989-05-01
891119
Quality assurance (QA) in motor vehicle emissions inspection/maintenance (I/M) programs is a continuing concern, especially in decentralized programs with hundreds or even thousands of licensed stations. The emissions analyzers used in such stations are an important focus of governmental QA efforts because of the central role of analyzers in determining which vehicles need to be repaired. Therefore, the In-use performance of I/M emission analyzers has a large impact on the quality of 1/M programs as a whole. This paper reports on the results of an investigation in California designed to determine in-use performance of emission analyzers in the field. The investigation was designed to evaluate both drift rates and the ability of analyzer systems with automatic gas calibration capability to correct analyzer responses outside of accepted tolerances.

ZINCROMETAL: Its Manufacture, Testing,and Use

1977-02-01
770362
ZINCROMETAL usage in the automotive sector has increased rapidly since 1972. As one might expect, this has led to considerable interest in the details of producing this product. In order to fulfill this expressed need, a description of the manufacture of ZINCROMETAL is presented here. Since the process is inextricably involved with a variety of quality control and quality assurance testing procedures, they are incorporated into this paper also. Finally, a long but incomplete listing of parts where ZINCROMETAL has been applied in auto bodies is reviewed.

What is Flight Inspection?

1997-05-01
971482
Flight Inspection is the Quality Assurance program which the Federal Aviation Administration uses to verify the performance of air navigation facilities and associated Instrument Flight Procedures. As an integral part of the National Airspace System, it is imperative that these facilities and procedures conform to the prescribed standards throughout their published service volume. This paper attempts to explain to the reader just how the FAA uses their Flight Inspection aircraft to accomplish that mission.

Welding and Joining of Magnesium

2001-10-01
2001-01-3443
The use of magnesium in a wide range of structures is expected to increase, together with the need to join it to other materials. Laser welding may be used for magnesium-magnesium joints, but other techniques will be needed for joining magnesium alloys to other materials, notably aluminium. It is shown that, for seam joints, friction stir welding is a contender, while self-piercing rivets and clinching are promising techniques for point joints. However, much further development needs to be done both to understand joint performance and to prove their industrial applicability.

Weight saving in small engine and vehicle component by utilization of die cast creep resistant alloys

2009-11-03
2009-32-0010
Magnesium alloys have been used and developed in applications for various motorcycle components and others such as cylinder head cover, crankcase and oil pan due to light weight, high specific strength and recycles ability. However, many of those alloys suffer from inferior die cast ability and high temperature properties, such as creep resistant. Ryobi limited has developed the creep resistant alloy in order to be utilized for the various motorcycle components and so forth. The properties of new die cast creep resistant alloy have been introduced. The targets for development of the properties of new alloy are the same creep resistant as aluminum die cast alloys and the same diecastability as ASTM magnesium alloys, such as AZ91D or AM60B alloys. Specific approaches of development with several types of evaluation have been performed for the purpose of fulfillment of this goal.
