Finite-time performance of a single-ion quantum Otto engine [PDF]
Phys. Rev. E 103, 032144 (2021), 2021 We study how a quantum heat engine based on a single trapped ion performs in finite time. The always-on thermal environment acts like the hot bath, while the motional degree of freedom of the ion plays the role of the effective cold bath. The hot isochoric stroke is implemented via the interaction of the ion with its hot environment, while a projective

Pengaruh Penambahan Langkah Kerja terhadap Unjuk Kerja Motor Bakar
Rekayasa Mesin, 2020 The duration of fuel-air diffusion in the 4 stroke combustion engine is relatively short, which is 0.02 seconds at 3000 rpm so that at high rotation the level of homogeneity of the fuel-air mixture becomes low.

Modeling of two-stroke aviation piston engines for control applications
Advances in Mechanical Engineering, 2023 Two-stroke Aviation Piston Engines are multivariable systems with severe non-linear dynamics, making their modeling challenging for control engineers. Although many studies have been conducted on simplified modeling of four-stroke gasoline engines and ...

SIX STROKE ENGINE ARRANGEMENT [PDF]
The International Conference on Applied Mechanics and Mechanical Engineering, 2012 In six stroke engine, there are additional two strokes, namely another power and exhaust strokes. The engine works through harnessing wasted heat energy created by the fuel combustion. After the combustion stage water is injected into the super- heated cylinder. The water explodes into steam and force the piston down.

The four-stroke reduction engine [PDF]
Proceedings of the 1986 ACM conference on LISP and functional programming - LFP '86, 1986 © 1986 ACM. Functional languages are widely claimed to be amenable to concurrent execution by multiple processors. This paper presents an algorithm for the parallel graph reduction of a functional program. The algorithm supports transparent management of parallel tasks vlth no explicit communication between processors.

Availing non-Markovian dynamics in effective negative temperature-based transient quantum Otto engines [PDF]
Phys. Rev. A 109, 022207 (2024), 2023 We demonstrate that the efficiency of effective negative temperature-based quantum Otto engines, already known to outperform their traditional counterparts operating with positive-temperature thermal reservoirs, can be further improved by terminating the isochoric strokes before the working substance reaches perfect equilibrium with its environment ...

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 ...
