Heat transfer affects the performance, emissions and durability of the engine as well as the design, packaging, material choice and fatigue life of vehicle components. This course covers the broad range of heat transfer considerations that arise during the design and development of the engine and the vehicle with a primary focus on computational models and experimental validation covering the flow of heat from its origin in the engine cylinders and its transfer via multiple paths through engine components. Specifically, the course will cover heat transfer design considerations related to the following: engine cooling and lubrication systems as well as bay-to-bay breathing; exhaust system and after-treatment components; tail pipe gas temperatures, as well as thermal interactions between the engine and its exhaust system with the components in the vehicle under-hood and under-body; turbochargers; passenger cabin HVAC system, including windshield de-icing; battery cooling; heat exchangers and challenges associated with predicting thermal mechanical fatigue life of components.

The In-Vehicle user environment is transitioning from fixed dedicated features to an extensible connected interface that can dramatically increase complexity faced by the driver. This course will provide a systematic design method to develop intuitive and safe vehicle interface solutions. Participants will learn user interaction design steps, tools, and the team synergies required to develop an interface from concept to the final product. The course will use exercises to practice interface design, with example interfaces to cover lessons learned. Participants will learn key interaction elements and principles to build a robust and flexible interface.

The abundance of personal electronic devices is causing a shift in individual expectations of personal mobility. These expectations are conflicting: consumers desire personalization of their devices, but manufacturers strive for commonality; some consumers view personal mobility as a chore, others as an expression of their individuality. We will explore these dichotomies, and discuss the near and mid-term shifts in the expectation of how consumers will perceive personal mobility devices.

In scooters, the Continuously Variable Transmission(CVT) is used to transmit the power from the engine to the wheels. The CVT transmission consists of a two pulleys connected to each other through a belt . The change in the transmission ratio is achieved due to the change in the pulley diameters. A centrifugal clutch is attached to the rear pulley to transmit the power to wheels once the engaging engine speed is reached. The heat is generated due to the belt slippage and the engagement of the centrifugal clutch. Excessive heating may damage the belt ,clutch and deteriorate its performance. The cooling of the belt , pulleys and the clutch is thus important for its safe operation. The cooling is achieved by the centrifugal cooling fan which forces the air over the belt, pulley and clutch. A clear understanding of the cooling system is important in designing the air flow path for clutch cooling of CVT housing. The efficiency of the cooling system depends on the quantity and direction of flow .

In our modern industrial civilization, the vast majority of mechanical work is produced by heat engines. While the efficiency of heat engines has improved over the years, they remain relatively inefficient, losing a significant portion of the input heat as waste heat. Waste heat recovery as a means of improving the overall efficiency of these engines in automotive applications has gained momentum in recent years. While many waste heat recovery (W.H.R) systems have been proposed and tested, the balance between, their efficiency, package size, the ease of being integrated to the drivetrain and most importantly cost, have made most nonviable. This paper introduces an alternative heat engine capable of harnessing waste heat, particularly for automotive applications. Theory: High temperature liquids held in a subcooled state are capable of storing energy and then explosively releasing this energy when depressurized, in a phase change process known as "Flashing". The rapid volume expansion that results from the flashing of superheated liquids to vapour has been harnessed to drive an expansion engine working on a cycle similar to the Rankine Cycle.

Abstract Automotive climate control systems are evolving at a rapid pace to meet the overall vehicle requirements and the user expectations for comfort and convenience. This poses a challenge in the product development life cycle of multi-platform vehicle systems with respect to development time and optimal performance in the Heating, Ventilation and Air Conditioning (HVAC) system. This paper proposes rapid HVAC plant model design and development using simplified one-dimensional (1D) simulation models for fast simulations. The specific accuracy limitations of such a simplified model are overcome using limited three-dimensional computational fluid dynamics (3D CFD) modelling. User-level control strategy is developed in an integrated simulation environment that includes a reference 1D model and a control algorithm simulator. The simulation data is used to study and analyse the temperature and airflow distribution in the system. Based on these results, simpler models for the HVAC system are derived.

Abstract Exhaust emission reduction and improvements in energy consumption will continuously determine future developments of on-road and off-road engines. Fuel flexibility by substituting Diesel with Natural Gas is becoming increasingly important. To meet these future requirements engines will get more complex. Additional and more advanced accessory systems for waste heat recovery (WHR), gaseous fuel supply, exhaust after-treatment and controls will be added to the base engine. This additional complexity will increase package size, weight and cost of the complete powertrain. Another critical element in future engine development is the optimization of the base engine. Fundamental questions are how much the base engine can contribute to meet the future exhaust emission standards, including CO2 and how much of the incremental size, weight and cost of the additional accessories can be compensated by optimizing the base engine. This paper describes options and potentials to improve the base engine for future commercial and industrial engines.

The need for energy-efficient thermal management (TM) provides a challenge for designers of vehicle systems. Papers are being solicited for efficient TM spanning the range from component concepts (phase change materials, electronics cooling, spray cooling, heat pipes/loop heat pipes, materials research, etc.) through system-level TM integration (integrated vapor cycle/air cycle hybridization, system-level impacts of single-phase vs. two-phase heat transport, etc.).
