“…Furthermore, several production applications already incorporate solutions such as PWM electro-fans, brazed radiators with complex geometry and high efficiency, controlled thermostatic valves, and variable water pumps [9,10]. However, implementing new technologies and more complex solutions in the automotive industry can be costly [11,12].…”

This study aims to enhance energy efficiency by reducing parasitic losses in the engine cooling system through a new drive strategy involving a two-stage water pump and a variable electro-fan. The fuel consumption gain analysis focused on a vehicle with average characteristics typical of 1.0L hatchbacks in the Brazilian market and urban driving conditions. The methodology implemented aims to minimize power absorbed by the forced water circulation and thermal rejection, thereby reducing parasitic losses, particularly during low-speed urban driving, without causing air-side heat exchanger saturation. The results show a potential decrease of up to 80% in power absorbed by the cooling system, leading to an estimated fuel consumption saving of approximately 1.4% during urban driving cycles.

“…They have also tended to look at energy efficiency through a homogenizing lens, posing one-size-fits-all solutions for different regions of the world (Hawkins et al 2013, Girardi et al 2015, Burchart-Korol et al 2018. Some studies have focused on the potential for specific demand-side mechanisms but have not developed specific scenarios that capture the contextual factors of specific countries (Chen and Kockelman 2016, Amatuni et al 2020, Migliore et al 2020, Yoo et al 2021. This presents a gap in identifying appropriate energy efficiency and demand-side mechanisms at a national level considering contextual characteristics to developing policies that will reduce the environmental impacts of passenger transportation.…”

Despite the deployment of low- or zero-emission technologies, achieving emissions reductions in the passenger transportation sector remains challenging. Demand-side mechanisms can be instrumental in reducing environmental impacts of transportation and reconfiguring transportation systems in a way that shifts users away from private car ownership.In this article we look at the Netherlands, Sweden, and the United States to quantify the environmental benefits from such shifts in passenger transportation, considering socio-technological drivers of transportation including well-being, digitalization, shared mobility, and electrification. We establish pathways for each of these countries considering their context. We frame these pathways using the avoid-shift-improve (ASI) framework which shapes the scenarios that we quantify in our analysis. We use a travel demand model as an input to calculate carbon, energy, and air pollution footprints. We quantify direct emissions considering the characteristics of the private fleet and indirect using multiregional input-output (MRIO) analysis.The results show that target thresholds can be reached under the proposed supply and demand initiatives. For the United States, these actions are more dramatic than for the Netherlands and Sweden due to that country’s stronger car dependence. A deep social transformation is needed to make these scenarios possible and enable a shift towards public, active and shared transportation in urban areas.
