The Automotive Seating Systems Report from IHS SupplierBusiness takes an in-depth look at the global seating market including the key changes currently underway in the industry and what the future holds for this sector. The report considers in-house seat manufacture and supply chain developments along with advances in safety, comfort and convenience. Fitment rates for various seat features such as powered and memory functions, lumbar support and massage have been increasing and will continue to do so as vehicle interiors become “smarter”. Much of the technology in today’s seats is electric or electronically driven, and can be remotely controlled via links on the dashboard or controllers located throughout the vehicle. The market is opening up to New Tier 1 suppliers as well as Tier 2 and specialist niche technology players, all of whom will intensify the competition for supplying the world’s leading seating companies.

Oil debris monitoring in aero engines In a gas turbine engine, small particles or "chips" are generated at the point of wear, serving as an advanced warning that catastrophic failure will occur if the wear is not addressed. Health monitoring systems, such as oil debris monitoring, are used to find these small particles so that the wear can be resolved before it's too late. Indigenous powertrain development Customer needs and expectations on drivability, fuel economy, and safety has pushed Indian and multinational OEMs to think about the development of powertrains and gearboxes for local needs with global standards. The next wave of crash simulation As computing speed has improved and software itself has made significant speed and performance gains with each release, modeling tools are now quick enough to build high-quality, large, high-detail vehicle models in a very efficient manner.

Abstract The Instant Mileage Assistance (IMA), as the name indicates, is a system to guide the vehicle users to realize maximum fuel economy (mileage). This system is targeted to provide users with instantaneous mileage indication depending on the current driving pattern, correct gear operating zone (in case of a geared vehicle) through gear up/down shift assist indication and the accurate distance the vehicle can travel before the fuel tank is empty, thereby assisting the user in harnessing maximum fuel economy the vehicle can deliver and also safely reach the next refilling station. The instantaneous mileage is calculated by mapping the distance travelled by the vehicle and the respective amount of fuel consumed, during a particular period of time, and is displayed using an instrument cluster.

Abstract In this paper, a light-duty exhaust heat recovery heat exchanger prototype is proposed to enhance the heating capacity of an automobile cabin. Even though the prototype is a small and simple structure of offset fins installed on a double tube, it showed a heat recovery capacity of more than 800 W. Therefore, the prototype is expected to be used in vehicles such as recreational vehicles and light utility vehicles with a cabin roof. The prototype was compared with a mass-produced model in tests of heat transfer and pressure drop performance by using hot air and a coolant. The results showed that the overall heat transfer coefficient for the prototype exceeded that for the mass-produced model for a Reynolds number of less than 1500.

Abstract The deposition of thick, pore-free, high-performance copper alloy matrix composite coatings is a topic of interest for several industrial applications, including friction materials, high-strength electrical contacts, and welding electrodes, among others. This study investigates the use of cold spray to deposit CuCrZr/Al2O3 cermet coatings on aluminum alloy 6060. The objective is to integrate copper-based materials with aluminum-based materials, ensuring a high degree of mechanical and thermal contact, using a low temperature process that does not adversely affect the properties of the base materials. This technique can be used to produce integral coolers and aluminum-based bearings for automotive and motorcycle applications. Fused and crushed alumina and gas-atomized CuCrZr powder blends have been used as initial feedstocks, with compositional weight ratios of 65/35 and 80/20 (ceramic/metal).

Abstract For detailed temperature estimates in the engine of a running motorcycle, newly researches were conducted on the method for calculation of temperature distribution using a three-dimensional (3D) thermal conductivity simulation after calculating the total balance of heat generation and heat dissipation of the engine using a one-dimensional (1D) thermal simulation. This project is targeted at air-cooled engines in which the cooling conditions vary significantly depending on the external shapes of the engines and the airflow around them. The heat balance is calculated using the 1D thermal simulation taking into account all the routes and processes for dissipation to the atmosphere of the heat that is generated by the combustion in the engine. The 1D engine cycle simulation is applied to calculate the heat transmission to the engine from the combustion. For the calculation of heat transfer within the engine, the engine components are converted to a one-dimensional model.

Abstract At a micro-CHP unit the target size of the engine controller is not mechanical torque but thermal and mechanical power. Accordingly, these demands must be implemented by the engine controller. This means that on the one hand a mechanical demand is answered under the boundary condition of the highest actual efficiency and that on the other hand thermal demands have to be processed. Since the thermal- and mechanical power output is coupled with the actual efficiency, exceeding the nominal load of the thermal power, the actual efficiency can be regulated in order to answer the demand. This can be done in consideration of the maximum achievable actual efficiency. Limits are set by the combustion stability and thermal protection functions. The functions are modelled with Matlab/Simulink and the ECU code for a rapid control prototyping system is generated. A dynamic engine test bed for internal combustion engines up to 12 kW was built to verify the motor control functions.

Abstract Recently, a potentiality of Dedicated EGR (D-EGR) concept SI engine has been studied. This concept engine had four cylinders and operated with exhaust gas supplied from the single cylinder to the intake manifold. Compared with conventional SI engines, it was able to increase thermal efficiency and decrease CO, HC, and NOx emission by the high D-EGR ratio 0.25. In this study, numerical analysis of a SI engine with D-EGR system with various D-EGR ratios was conducted for detailed understanding the potentiality of this concept in terms of thermal efficiency and NOx emission. #1 cylinder of assumed engine was used as D-EGR cylinder that equivalence ratio varied from 0.6 to 3.4. Entire exhaust gas from #1 cylinder was recirculated to the other cylinders. The other cylinders run with this exhaust gas and new premixed air and fuel with various equivalence ratios from 0.6-1.0.

Abstract It is known acoustic comfort is a key feature to meet customer expectations for many products. In the current automotive industry, vehicle interior quietness is seen as one of the most important product attributes regarding perceived quality. A quiet interior can be achieved through an appropriate balance of noise sources levels and acoustic materials. However, the choice of the most efficient acoustic content may be challenging under severe cost and mass restraints commonly found in emerging market vehicles. Therefore, it is fundamental to develop efficient materials which will provide high acoustic performance with lower weight and cost. In this paper the fine tuning of the headliner structure is presented as an efficient way to increase acoustic performance. Structures currently employed for this vehicle subsystem are described. Airflow resistance and sound absorption measurements are used to guide development and make precise manufacturing process changes.

Abstract Air conditioning systems are being increasingly applied in the Brazilian automotive industry becoming indispensable rather than an optional item for car buyers, who are constantly seeking out more comfort. Conversely, the application of these systems in motor vehicles involve the use of compressors which operate at high pressures, making them important sources of vibration and unwanted noise in the cabin of the vehicle, thus causing vibratory discomfort and noise annoyance. Despite the major technological developments in automotive air conditioning systems, there is still a shortage of engineering research conducted in the field of vibration and noise originated in these particular systems. The present study is aimed at investigating and characterizing experimentally the vibration and acoustic propagation in the interior of a vehicle, generated by the compressor of the air conditioning system.

Abstract Fuel consumption of vehicles has received increased attention in recent years; however one neglected area that can have a large effect on this is the energy usage for the interior climate. This study aims to investigate the energy usage for the interior climate for different conditions by measurements on a complete vehicle. Twelve different NEDC tests in different temperatures and thermal states of the vehicle were completed in a climatic wind tunnel. Furthermore one temperature sweep from 43° to −18°C was also performed. The measurements focused on the heat flow of the air, from its sources, to its sink, i.e. compartment. In addition the electrical and mechanical loads of the climate system were included. The different sources of heating and cooling were, for the tested powertrain, waste heat from the engine, a fuel operated heater, heat pickup of the air, evaporator cooling and cooling from recirculation.
