Abstract In this work we have proposed an interesting clamping solution of V-band which has an important industrial impact by reducing the cost and assembly process as well compare to the traditional V-band. The design what we are focusing for is applied for all size of turbochargers which helps to connect the hot components such as manifold and turbine housing. The cost for V-band is mainly from T-bolt. It is made from special stainless steel which represents 50% of the total cost. In this work it is proposed a new V-band joint by changing bolt clamping status from tension to compression. From tension to compression we change the bolt material from high cost steel to low cost steel. The new total cost is reduced by 40%. The prototype is made and performed in static tests including anti-rotating torque test and salt spray test. The new joint meets the design requirements at static condition. Further work will focus on the dynamic qualification and at high temperature as well.

Abstract Health Ready Components are essential to unlocking the potential of Integrated Vehicle Health Management (IVHM) as it relates to real-time diagnosis and prognosis in order to achieve lower maintenance costs, greater asset availability, reliability and safety. IVHM results in reduced maintenance costs by providing more accurate fault isolation and repair guidance. IVHM results in greater asset availability, reliability and safety by recommending preventative maintenance and by identifying anomalous behavior indicative of degraded functionality prior to detection of the fault by other detection mechanisms. The cost, complexity and effectiveness of the IVHM system design, deployment and support depend, to a great extent, on the degree to which components and subsystems provide the run-time data needed by IVHM and the design time semantic data to allow IVHM to interpret those messages.
Porsche, Audi, Toyota, and Nissan each chose a different path for its hybrid-electric prototype racer at Le Mans, but one solution rose to the occasion.
To reduce cost and improve performance in engines, Honeywell is offering a software tool to embed virtual sensors in engines, using first-principles models that resides in the engine control unit.
As the proliferation of and demand for “smart” technology in off-highway vehicles has risen, so has the notion that sensors are the only suitable solutions for these control loops. The switch, meanwhile, tends to be viewed as an antiquated and irrelevant technology of legacy systems.

Turbochargers are widely used to boost internal combustion engines for both on and off high way applications to meet emission and performance requirements. Due to the high operating temperature, turbochargers are subjected to hostile environment. Low vibration level is one of the key requirements while designing turbo for every application. An engine bracket is employed to support turbine housing to reduce total vibration level. Turbine housing in the turbocharger is commonly equipped with boss to accommodate the engine bracket supporting which eventually includes additional constraints in the turbocharger system. Additional constraints in the turbine housing can lead to adverse impact in the Thermo-Mechanical Fatigue (TMF) life of the housing component. Boss generally has critical influence to thermal stress distribution of the turbine housing.

Interior Climate Control Committee reactivates development of standards for R-744 mobile air-conditioning (carbon dioxide as a refrigerant), after several German automakers choose to renew work on a system. R-1234yf maintains worldwide lead as low-global-warming refrigerant choice to replace R-134a. German association of the auto industry (VDA) assigns R-744 development work to automakers.
Dassault Aviation has built into its upcoming Falcon 5X flight controls and displays experience not only from the Falcon family of business jets but also from the Rafale multi-role combat fighter.
The push to trim fuel consumption and emissions may prompt aircraft manufacturers to adopt some of the electric motor technologies used in hybrid cars and trucks.
New R-1234yf production is promised by Arkema. SAE Cooperative Research Group shows R-445A blend has potential, and vehicle prototype charging equipment for assembly line and service shop is undergoing testing. German automakers resurrect the R-744 (carbon dioxide as a refrigerant) development program.
Chromalloy signed 10-year repair license and supplier agreements with Honeywell. The agreements cover aircraft engine components and engineering services for parts, and special coating processes. Chromalloy will repair and manufacture gas path components and provide thermal barrier coatings and other materials for aircraft engines.
Honeywell and Embraer signed an agreement worth $2.8 billion over its lifetime to provide Honeywell's Primus Epic as the integrated avionics system for Embraer's second-generation of the E-Jet aircraft family.
Daimler's decision to halt use of the new refrigerant on safety concerns leads to a product defense by joint-venture suppliers Honeywell and DuPont, citing SAE studies and their own tests. Although GM is the only U.S. maker with R-1234yf cars, Ford also backs the refrigerant's use.

The operating environment of aircraft causes accumulation and build-up of contamination on both the narrowest passages of the ECS (Environmental Control System) i.e: the heat exchangers. Accumulated contamination may lead to reduction of performance over time, and in some case to failures causing AOG (Aircraft on Ground), customer dissatisfaction and elevated repair costs. Airframers/airlines eschew fixed maintenance cleaning intervals because of the high cost of removing and cleaning these devices preferring instead to rely on on-condition maintenance. In addition, on-wing cleaning is t impractical because of installation constrains. Hence, it is desirable to have a contamination monitoring that could alert the maintenance crew in advance to prepare and minimize disruption when contamination levels exceed acceptable thresholds. Two methods are proposed to achieve this task, The effectiveness of these methods are demonstrated using analytical and computational tools.

Natural atmospheric radiation effects have been recognized in recent years as key safety and reliability concerns for avionics systems. Atmospheric radiation may cause Single Event Effects (SEE) in electronics. The resulting Single Event Effects can cause various fault conditions, including hazardous misleading information and system effects in avionics equipment. As technology trends continue to achieve higher densities and lower voltages, semiconductor devices are becoming more susceptible to atmospheric radiation effects. To ensure a system meets all its safety and reliability requirements, SEE induced upsets and potential system failures need to be considered. The purpose of this paper is to describe a process to incorporate the SEE analysis into the development like-cycle. Background on the atmospheric radiation phenomenon and the resulting single event effects, including single event upset (SEU) and latch up conditions is provided.

The goal of the presented research is to study the effective operational range for a centrifugal vaneless diffuser turbocharger compressor with ported shroud typically used in diesel engines. A turbocharger bench facility was designed and tested in order to define the performances of the compressor and to better understand the occurrence of instabilities in the housing. Specific emphasis was given to the low mass flow rate region of the compressor performance characteristics where instabilities occur with fluctuations that can be significantly large in the case of surge. Static pressures and dynamic pressure fluctuations were measured at the inlet, the outlet, as well as at different positions around the volute and diffuser sections of the compressor in order to assess the development and propagation of flow instabilities. The dynamic signature of the flow was measured along with the elaboration of the compressor mapping.
