Investigations of Process and Component Parameters for the Number of Particles and Size Distribution of a Supercharged DI-SI Engine2022-01-070003/29/2022
Due to the short mixture formation times in the direct injection of modern gasoline engines, there is an increase in the emission of undesirable particle emissions in gasoline engines. As a result of previous studies with a portable emission measurement system (PEMS) of raw emissions and cleaned emissions, the particle number (PN) of the sampling point after the catalyst was higher than before the catalyst at the same process parameters and engine operating points. Based on this reproducible phenomenon, several theories were proposed. The theories set up dealt on the one hand with the question of process control with regard to the formation of particles, but also fundamentally with the question of whether conventional exhaust gas aftertreatment systems (3-way catalytic converters) are suitable for influencing the number of particles. In addition, studies of the oil consumption via the blow-by system and its influence on particle emissions also played a role. To verify these theories

Application of Selective Assembly as an Aerospace Design for Manufacturing and Assembly Principle for Effective Variation Management in Aerospace Assemblies2021-01-000503/02/2021
Aerospace engine parts are complex precision-engineered products with tighter assembly tolerances produced by conventional and non-conventional manufacturing processes. Variations in these manufacturing processes have to be controlled, process risks mitigated, and managed effectively, to facilitate the ease of aero-engine assembly to reduce overall variation and improve the assembly quality. One such technique is the application of the Selective Assembly as a Design for Manufacturing and Assembly (DfMA) tool. The paper details the methodology of Selective Assembly, its applications, benefits, and limitations in the aerospace industry along with a framework case study with a focus on ease of assembly and meeting the design intent of the assembly fit with the detailed study on the current traditional assembly process. The focus is to analyze the current challenges faced on the application of the Selective assembly of Aero-engine components through a case study on the development and

Application of Metrology, Statistics, Root Cause Analysis, and Cost of Quality to Enable Quality Improvements and Implementation of Statistical Process Controls for Acceptance of Large Complex Assemblies2021-01-002503/02/2021
For new aircraft production, initial production typically reveals difficulty in achieving some assembly level tolerances which in turn lead to non-conformances at integration. With initial design, tooling, build plans, automation, and contracts with suppliers and partners being complete, the need arises to resolve these integration issues quickly and with minimum impact to production and cost targets. While root cause corrective action (RCCA) is a very well know process, this paper will examine some of the unique requirements and innovative solutions when addressing variation on large assemblies manufactured at various suppliers. Specifically, this paper will first review a completed airplane project (Project A) to improve fuselage circumferential and seat track joins and continue to the discussion on another application (Project B) on another aircraft type but having similar challenges. The use of Project A and B is used here to ensure proprietary protection of internal and supplier

Single-Use Applications Maximize Biomanufacturing AgilityTBMG-3806611/01/2020
Biopharmaceutical manufacturing is changing. With the rise of biologics and personalized medicine, the industry is appreciating the single-use manufacturing style. Instead of large-scale production processes, manufacturers are finding it pays to be agile — which is why many are increasingly adopting single-use technologies to turn over new products and batches quickly and efficiently. Single-use technologies utilize disposable bioprocessing equipment in place of traditional stainless steel. By eliminating the time-consuming clean-in-place (CIP) and steam-in-place (SIP) processes between batches, single-use technologies cut down on the costs of labor, materials, and utilities — all while shortening time to market.

Microstructure-Fatigue Property Relationships for Cast Irons2020-01-018704/14/2020
Cast irons are widely used for combustion engine/exhaust system applications, not only because they are less expensive but also because they offer some attractive properties such as good thermal conductivity, relatively high specific yield strength, and good oxidation resistance. Cast irons can be made with a wide variety of microstructures containing either flake-like graphite (FG), nodular graphite (NG) or vermicular graphite (VG), or mixing of the above, which control their mechanical and fatigue properties. In this paper, a microstructure-fatigue property relationship model is developed, combining the Tanaka-Mura-Wu’s fatigue crack nucleation model with Eshelby’s solution for materials containing ellipsoidal inclusions. This applies to cast irons considering its microstructural graphite characters (shape, size, elastic modulus and Poisson’s ratio). This model is used to analyse ductile cast iron (DCI) with nodular graphite (NG) microstructure, grey cast iron (GCI) with flake-like

Avoidance of Hydrogen Embrittlement of SteelUSCAR5-5 (Current)02/27/2019
This standard outlines the conditions that enhance the risk of hydrogen embrittlement of steel and defines the relief procedures required to minimize the risk of hydrogen embrittlement. It is intended to control the process. Hydrogen embrittlement of steel, which can cause brittle fractures under stress, occurs as a result of the absorption of hydrogen during cleaning, phosphate coating and plating processes. The susceptibility to hydrogen embrittlement increases with increasing stress (internal or externally applied stress) and increasing material strength. Hardness readings in this specification are in Vickers scale. SAE J417 should be referred to for conversion to other scales.
