We use micro-level data on fuel consumption, mileage, and travel mode to study plug-in hybrid drivers’ response to fuel prices. When fuel prices rise, plug-in hybrids reduce fuel consumption more than gasoline and diesel cars. They do not reduce their mileage but increase electric recharging,...

We provide a framework for setting congestion charges that reflect emission and congestion externalities and policy responses, such as vehicle ownership, driving, and residential sorting. Using Swedish administrative microdata, we identify these responses by exploiting a temporary exemption for...

The number of passenger cars in Germany has increased continuously in recent years and reached a new high of 48.8 million in 2023. This means that on average, there are 1.2 passenger cars for the 40.7 million households in Germany. On average, new registra-tions amount to 3.1 million vehicles...

Im vergangenen Jahr waren die Zuwachszahlen im Bereich der Elektromobilität in Deutschland höher als jemals zuvor. Das enorme Wachstum ist vor allem der EU-Verordnung zur Flottenemissionsnorm zu verdanken. Die Elektromobilität hat damit einen wichtigen Schritt gemacht und gezeigt, dass sie...

Zur Sicherstellung der Vergleichbarkeit des Emissions- und Verbrauchsverhaltens von Kraftfahrzeugen ist es von entscheidender Bedeutung, dass die Randbedingungen während des Tests in engen Grenzen einheitlichen Vorgaben folgen. Der Gesetzgeber sieht hierfür genormte Geschwindigkeits-Zeit-...

The main advantage of hybrid powertrains is based on the efficient transfer of power and torque from power sources to the powertrain as well as recapturing of reversible energies without effecting the vehicle performance. The benefits of hybrid hydraulic powertrains can be better utilized with...

Der Beitrag stellt zunächst ein weiterentwickeltes Vorgehensmodell zur Entwicklung mechatronischer Systeme vor, das das u.a. aus der VDI-Richtlinie 2206 bekannte V-Modell um die Phase des Systembetriebs sowie um eine zeitliche Dimension ergänzt und auf diese Weise zu einem Kreismodell bzw....

This study examines attention effects in the market for hybrid vehicles. We show that local media coverage, gasoline price changes and unprecedented record gasoline prices have a significant causal impact on the consumers’ attention. As attention is not directly observable, we analyze online...

Emerging green-energy transportation, such as hybrid electric vehicles (HEVs) and plug-in HEVs (PHEVs), has a great potential for reduction of fuel consumption and greenhouse emissions. The lithium-ion battery system used in these vehicles, however, is bulky, expensive and unreliable, and has...

The development of hybrid and fully electric vehicles could deliver significant reductions of emissions from the Australian transportation sector by shifting its major energy source from internal combustion to electricity. This shift towards the the use of electricity shifts the point source...

This paper outlines a method for optimizing the design of a lithium-ion battery pack for hybrid vehicle applications using a hybrid numerical optimization method that combines multiple individual optimizers. A gradient-free optimizer (ALPSO) is coupled with a gradient-based optimizer (SNOPT) to...

The hybrid method is effective for energy savings. This paper presents an energy efficient hydraulic hybrid propulsion system for automobiles. The system consists of hydraulic common pressure rail, hydraulic transformer and hydraulic pump or motor. The parameter design and propulsion...

In this work the differences between the thermodynamic behaviour of real and ideal gases are analysed to determine their influence on the processes of compression and expansion of a gas-charged accumulator. The behaviour of real gas has a significant influence on the size of accumulators used...

A longstanding interest of the Authors' research group at University of Roma Sapienza (UDR1) is the design, development and fielding of a road prototype of a new concept of Hybrid Series vehicle, endowed with a small Gas Turbine set as a thermal engine. This solution offers several advantages...

The Atkinson cycle engines have larger expansion ratio, thus higher thermal efficiency, which are more suitable for the hybrid fuel-electric vehicles than the conventional Otto cycle engines. Larger expansion ratio in an Atkinson cycle engine can be realized by increasing the geometrical...

"This book analyzes how the governance of innovation can foster sustainability. The quest for innovation is consistently at the top of the agenda for policy makers around the globe, on the supra-national level, as well as for the nation states and all the way down to debates in local governance...
