Emission free compressed air powered energy system can be used as the main power source or an auxiliary unit in vehicular transportation with advantages of zero carbon emissions and improved overall efficiency integrated system. This work presented a detailed technological development compressed-air systems. The studies on powertrain transport sector are summarised including design new valve te...

In this paper, a novel Equivalent Consumption Minimization Strategy (ECMS) is developed for a series hybrid powertrain system, based on the flow of energy through energy sources and components. The performance of the controller is assessed using both urban and highway drive cycles, through comparing results for the series hybrid powertrain system against a comparable conventional powertrain. Fu...

Abstract: In hybrid electric vehicles with power-split configurations, the engine can be decoupled from the wheel and operated with improved fuel economy, while the entire efficiency of the powertrain is affected by the circular electric power flow. Two planetary gear (2-PG) sets with adding brakes/clutches, namely a type of four shaft elelctric continuously variable transmission (ECVT) can pro...

There are possibilities to reduce the fuel consumption in trucks using hybrid technology. New components are added when hybridizing a vehicle, and these need to be monitored due to safety and legislative demands. Diagnosis aspects due to hybridization of the powertrain are investigated using a model of a long haulage truck. Such aspects are for example that there are more mode switches in the h...

As part of the Challenge X competition, the University of Tennessee has chosen a hybrid electric powertrain architecture for conversion of a 2005 Chevrolet Equinox SUV to a more fuel efficient and environmentally responsible vehicle. A brief overview of the powertrain configuration is presented, as well as the corresponding supervisory control system architecture. The methodology for developing...

In the context of hybrid electric and full powertrains for future less-pollutant aircrafts, this paper focuses on multidisciplinary design optimization (MDO) actuation system, including a surface-mounted PMSM in order to maximize power density device: study is preliminary approach before integrating whole powertrain. After an introduction MDO context, analytical model motor detailed. It integra...

Tractors are usually applied in field operations, road transport, and other operations. Modern agriculture has higher design requirements for tractor powertrains due to the complicated working environments various To meet driving of under multiple a mechanic-electronic-hydraulic powertrain system (MEH-PS) tractors been designed according characteristics hydro-mechanical composite transmission e...
