I made a presentation where I derived, or at least attempted to derive, the formulae for the upper bounds of the efficiency/cop (cop = coefficient of performance) for a heat engine, work driven heat pump, and a heat driven heat pump with 3 thermal reservoirs, hot, warm, and cold. The...
The system consists of two compact, powerful electric motors that work alongside an Atkinson-cycle 1.5-litre DOHC i-VTEC petrol engine, a lithium-ion battery and an innovative fixed-gear transmission coupled to an intelligent power control unit. The e:HEV powertrain is already...

According to this formula, the only parameters that need to be determined are the α and ξe-ξh. For an ideal OLED, ξe-ξh is suggested to be equal to the voltage biased to the contact of the OLED. Also, the absorption distribution parameter can be simplified as the narrow ...
The article reviews the existing methods of increasing the energy efficiency of electric transport by analyzing and studying the methods of increasing the energy storage resource. It is grouped according to methods, approaches, and solutions. The most ef

The most common are hybrid cars powered by a “tandem”, consisting of an internal combustion engine (petrol or diesel) and an electric unit [1,2,3]. However, not all combustion–electric drives are the same and can be divided into the following three main groups: the plug-in hybrid (...
Transport costs are strongly influenced by fuel prices and fuel consumption in transport, i.e., energy efficiency. The aim of the article is to present the problem of energy efficiency in freight transport with the use of Heavy Duty Vehicles (HDV). The authors presented the factors of energy...
However, these studies have limitations due to evaluating the energy efficiency of vessel fisheries without considering essential input factors such as crew, vessel size, and the engine’s power. To overcome the limitations of previous studies in the fisheries sector, we adopted the SFA model that...
