“…For instance, reducing the EC weight decreases the vehicle fuel consumption 10,11 by reducing the mechanical propulsion energy demands. Also, reducing the vehicle frontal surface by reducing the EC component size, such as the radiator in the case of ICE or the proton-exchange membrane fuel cell (PEMFC), 12,13 reduces the vehicle fuel consumption by reducing the aerodynamic drag resistance power. Furthermore, increasing the EC efficiency reduces the fuel consumption since less amount of fuel is burnt for a same EC output power required.…”

Gas turbine systems are among potential energy converters to substitute the internal combustion engine as auxiliary power unit in future series hybrid electric vehicle powertrains. Fuel consumption of these auxiliary power units in the series hybrid electric vehicle strongly relies on the energy converter efficiency and power-to-weight ratio as well as on the energy management strategy deployed on-board. This paper presents a technological analysis and investigates the potential of fuel consumption savings of a series hybrid electric vehicle using different gas turbine–system thermodynamic configurations. These include a simple gas turbine, a regenerative gas turbine, an intercooler regenerative gas turbine, and an intercooler regenerative reheat gas turbine. An energetic and technological analysis is conducted to identify the systems’ efficiency and power-to-weight ratio for different operating temperatures. A series hybrid electric vehicle model is developed and the different gas turbine–system configurations are integrated as auxiliary power units. A bi-level optimization method is proposed to optimize the powertrain. It consists of coupling the non-dominated sorting genetic algorithm to the dynamic programming to minimize the fuel consumption and the number of switching ON/OFF of the auxiliary power unit, which impacts its durability. Fuel consumption simulations are performed on the worldwide-harmonized light vehicles test cycle while considering the electric and thermal comfort vehicle energetic needs. Results show that the intercooler regenerative reheat gas turbine–auxiliary power unit presents an improved fuel consumption compared with the other investigated gas turbine systems and a good potential for implementation in series hybrid electric vehicles.

“…Engine cooling technologies, including conventional and subcooled systems have been excellently reviewed, from different perspectives, in 2004, 1 in 2005 2 and more recently in 2010. 3 Conventional systems are, however, reaching their limits for efficient thermal management, in particular for aggressively downsized, highly boosted engines. This limitation motivates the search for alternative cost-effective, efficient, durable and controllable cooling systems.…”

“…The proposed cooling system is specific to the retarder and was shown to be significantly more effective. Lin and Sunden [3] published a literature survey on vehicle cooling systems for reducing fuel consumption and CO2 emissions. This included not only those for engine cooling but also air conditioning, cooling of electronics, and cooling of parts affected by friction.…”

The evaporative cooling system concepts proposed over the past century for engine thermal management in automotive applications are examined and critically reviewed. The purposes of this review are to establish the evident system shortcomings and to identify the remaining research questions that need to be addressed to enable this important technology to be adopted by vehicle manufacturers. Initially, the benefits of the evaporative cooling systems are restated in terms of the improved engine efficiency, the reduced carbon dioxide emissions and the improved fuel economy. This is followed by a historical coverage of the proposed concepts dating back to 1918. Possible evaporative cooling concepts are then classified into four distinct classes and critically reviewed. This culminates in an assessment of the available evidence to establish the reasons why no system has yet been approved for serial production commercially. Then, by systematic examination of the critical areas in evaporative cooling systems for application to automotive engine cooling, the remaining research challenges are identified

“…Reducing the amount of energy lost in engine and passenger compartment space cooling systems will enhance the efficiency of the vehicles. 2 Considerable progresses have been made over the last 20 years by the integration and miniaturization of sensors and electronic controls of cooling system components. A traditional cooling system is made up of (i) pump, (ii) thermostat valve, (iii) heat exchanger and (iv) cooling fan.…”

In recent years, a considerable effort has been devoted towards the application of advanced techniques for turbomachinery efficient fluid dynamic control during operations. A novel strategy to dynamically modify and optimize the performance during operations takes advantage of shape memory alloys properties. Experimental and numerical analyses on a morphing polymeric blade for an automotive axial fan are presented. The blade shape change was achieved by shape memory alloys strips, thermomechanically treated, embedded in the blade and thermally activated by hot air stream flow. Measurement of fluid temperature, blade surface temperature pattern and three-dimensional shape change of the blade during activation was performed by means of an innovative image analysis technique in a purpose-built wind tunnel. Computational fluid dynamics numerical simulations were performed to study performance variations and three-dimensional fluid dynamic behavior of the fan originated from the shape memory effect.
