Single-cylinder 125 cc Stepped-piston Engine for Mobility and Portable Power Generation Applications [PDF]
International Journal of Technology, 2016 Two-stroke engines are far simpler than four-stroke engines from a physical perspective. For a given brake output, two-stroke engines are lighter, easier to work on, and provide higher power-to-weight ratio than four-stroke engines, making them ...

Measurement driven single temperature engine [PDF]
Phys. Rev. E 98, 042122 (2018), 2018 A four stroke quantum engine which alternately interacts with a measurement apparatus and a single heat bath is discussed in detail with respect to the average work and heat as well as to the fluctuations of work and heat. The efficiency and the reliability of such an engine with a harmonic oscillator as working substance are analyzed under different ...

Non-Markovian thermal operations boosting the performance of quantum heat engines [PDF]
Phys. Rev. E 106, 014114 (2022), 2022 It is investigated whether non-Markovianity, i.e., the memory effects resulting from the coupling of the system to its environment, can be beneficial for the performance of quantum heat engines. Specifically, two physical models are considered. The first one is a well known single-qubit Otto engine; the non-Markovian behaviour is there implemented by ...

Two-Stroke Wankel Type Rotary Engine: A New Approach for Higher Power Density
Energies, 2019 The Wankel engine is a rotary type of four-stroke cycle internal combustion engine. The higher specific power output is one of its strong advantages. In Wankel rotary engine, every eccentric shaft revolution corresponds to one four-stroke cycle, whereas ...

Stroboscopic two-stroke quantum heat engines [PDF]
Phys. Rev. A 102, 042217 (2020), 2020 The formulation of models describing quantum versions of heat engines plays an important role in the quest toward establishing the laws of thermodynamics in the quantum regime. Of particular importance is the description of stroke-based engines which can operate at finite-time.

Catalytic enhancement in the performance of the microscopic two-stroke heat engine [PDF]
Phys. Rev. E 110, 044120 (2024)We consider a model of heat engine operating in the microscopic regime: the two-stroke engine. It produces work and exchanges heat in two discrete strokes that are separated in time. The working body of the engine consists of two $d$-level systems initialized in thermal states at two distinct temperatures.

Scavenge flow analysis of opposed-piston two-stroke engine based on dynamic characteristics
Advances in Mechanical Engineering, 2015 Opposed-piston two-stroke engine has been proposed by Beijing Institute of Technology to improve power density and complete machine balance relative to conventional engines. In order to study opposed-piston two-stroke engine scavenging flow, a scavenging
