DEVELOPMENT OF VEHICLE INFOTAINMENT DISPLAYS BASED ON LEGIBILITY AND READABILITY REQUIREMENTS

2020-09-25
2020-28-0321
Vehicle infotainment displays are the displays that the driver need to look at during driving for getting critical information or entertainment related information’s. It can be seen that the time available to glance these screen while driving is very less and it is directly related to the driving safety. Hence it is critical to have these displays readable and legible. The legibility and readability of text, pictures on the display screens (Includes the instrument cluster and center console displays) is critical since it is combination of the available space and geometric constraints. The instrument cluster position is constrained by the instrument panel packaging and size / diameter of the dials of instrument cluster. Hence the text size should be decided based on the position of display which will be legible and readable for all target population users from their designated seating position.

The continuous efforts are been put by production engineers and process planning engineers to reduce or maintain minimum manufacturing lead time. The existing radial drilling machine took 184s for grooving six-holes in the tie rod. The operator has produced the six grooves by repositioning the tie rod in the fixture. The total machining time required for completing one tie rod is 184s out of which 138s were machining time and the remaining 46s was material handling time. In the present work design and fabrication of multi-spindle drilling, the head is done for increasing the production capacity of the manufacturing unit. The other merits of this design are quality and quantity products by minimizing operator fatigue. The methodology followed to accomplish the above work included concept development Process and modeling. Design calculations and finite element analysis were carried out on the critical part such as gear and gear on the shaft for design validation.

The Variation of Functional Characteristics of a EURO VI Selective Catalytic Reduction Reactor after Ageing

2020-09-15
2020-01-2205
The selective catalytic reduction (SCR) of nitrogen oxides by ammonia is commonly applied as a method of exhaust aftertreatment for lean burn compression ignition engines. The catalytic reactor of a SCR system, as all catalytic emission control devices, is susceptible to partial deactivation as its operating time progresses. Long-term exposure of an SCR reactor to exhaust gas of fluctuating temperature and composition results in variations of the characteristic of its catalytically active layer. The conducted research aimed to observe and investigate the variation of parameters characterizing the SCR reactor as a result of its ageing. Attention was paid to changes in ammonia storage capacity, selectivity of chemical reactions and maximum achievable NOx conversion efficiency. The experimental setup was a heavy duty EURO VI-compliant engine and its aftertreatment system. The setup was installed on a transient engine dyno instrumented with emission measurement devices.

A comparison of the flame structure for two different fuels, dodecane and oxymethylene dimethyl ether (OMEX), has been performed under condition of Spray A of the Engine Combustion Network (ECN). The experiments were carried out in a constant pressure vessel with wide optical access, at high pressure and temperature and controlled oxygen concentration. The flame structure analysis has been performed by measuring the formaldehyde and OH-radical distributions using Planar Laser-Induced Fluorescence (PLIF) techniques. To complement the analysis, this information was combined with that obtained with high speed imaging of natural luminosity and OH chemiluminescence radiation in the UV. Formaldehyde molecule is excited with the 355nm radiation from the third harmonic of a ND:YAG laser, whilst OH is excited with 281 nm wavelength from a dye laser.

Accelerated Aging Method of Three Way Catalyst Run on Test Bed with Emission Performance and Oxygen Storage Capacity Evaluation

The aim of this paper was to describe a method of accelerated three way catalyst (TWC) aging performed on a test bed for OBDII monitoring purposes and screening of different catalyst solutions. To accelerate the catalyst aging process, the exhaust gas temperature was elevated to a range above 1150°C, which is typical for an aging cycle performed using ovens. Catalyst emissions performance was checked at new condition (after degreening) and subsequently at predefined intervals, based on the oxygen storage capacity (OSC) evaluation. The emission tests were performed in the laboratory on the chassis dynamometer using legislation cycles. The accelerated aging method was found to be of use for verifying the EOBD functionality under vehicle operation with a degraded catalyst substrate.

Particulate Contamination in Biodiesel Fuel under Long-Term Storage

2020-01-2143
Many incidents associated with filter plugging have extensively been reported in microbially contaminated diesel and biodiesel fuel systems, especially under long term storage conditions. In this study a quantitative assessment of the undesirable insoluble solids produced in contaminated biodiesel fuels was carried out in order to evaluate their evolution rate during biodeterioration. For this purpose, a series of contaminated biodiesel fuel microcosms were prepared and stored for six months under stable conditions. The quantity of the particulate contaminants was monitored during storage by a multiple filtration method which was followed at the end by a comparison with the active bioburden per ATP bioluminescence protocol. Additional similar microcosms were treated with a commercially available biocide in order to examine the latter’s activity both on solids formation and the microbial proliferation.

REAL-e: Robust and Affordable IoT Solution for In-Service Conformity Testing

2020-01-2187
REAL-e: Robust and affordable IoT solution for in-service conformity testing Since 2019 in-service conformity testing for vehicles as described in EU legislation 2018/1832 is active and obliges numerous emission control tests on WLTP and RDE cycles. For the on-road portion of these tests typically Portable Emissions Measurement System (PEMS) are used. While these systems provide all necessary regulated emissions measurements, their use and handling are difficult due to their weight, cumbersome installation, and their limited accessibility due to a high price point. In order to make the real-driving measurement accessible for a maximum of institutions, IFPEN is developing with REAL-e a compact measurement system with an advanced cloud modeling of the vehicle for more cost-effective and user friendly RDE and ISC testing. REAL-e is based on a combination off-the-shelf and in-house sensors build in a compact and easy-to-maintain packaging.

e-Fuel Production via Renewables and the Impact on the In-Use CO2 Performance

2020-09-15
2020-01-2139
The trend towards renewable energy sources will continue under the pre-amble of GHG emission reduction targets. The main question is how to harvest and store renewable energy properly. The challenge of intermittency of the renewable energy resources make the supply less predictable compared to the traditional energy sources. Chemical energy carriers like hydrogen and synthetic fuels (e-Fuels) seem to be at least a part of the solution for storing renewable energy. The usage of e-Fuels in the existing ICE-powered vehicle fleet has a big lever arm to reduce the GHG emissions of the transport sector in the short- and medium term. The paper covers the whole well-to-wheel (WtW) pathway by discussing the e-Fuel production from renewable sources, the storage and the usage in the vehicle. It will be summarized by scenarios on the impact of e-Fuel to the WtW CO2 fleet emissions.

The selection of aircraft consumable materials in aerospace manufacturing and assembly processes is a major customer design data-driven process, which is designed and developed early at the product design stages. With the rapid improvements in the aerospace manufacturing and assembly industry, these consumable material sources are prone to both obsolescence and counterfeit risks. Thus, aircraft design teams must carefully identify the selection of these materials and sources, which can provide products and services till the end of the product life cycle, which, if not, can impact both the design and the functional intent of the aircraft assembly. The study discusses the challenges faced in the current aerospace consumable industry and the opportunities for improvement in it.
