quantum otto cyclewave-functionoptimal work outputefficiencyAn idealized reversible Otto cycle working with a single quantum mechanical particle contained in a potential well is investigated based on the Schrdinger equation in this paper. The model of a reversible quantum Otto cycle, which consists of...
We now consider a general two-heat-source heat engine, which may be Carnot cycle, Brayton cycle, Diesel Cycle, or Otto cycle, etc55. The diagram of such a heat engine is illustrated in Fig. 1. The cyclic heat engine gets the working subsystem back to its original state at the end of...
Radial engines have a relatively low maximum rpm (rotations per minute) rate, so they can often drive propellers without any sort of reduction gearing. Because all of the pistons are in the same plane, they all get even cooling and normally can be air-cooled. That saves the weight of wate...
Almost every car with a gasoline engine uses afour-stroke combustion cycleto convert gasoline into motion. The four-stroke approach is also known as theOtto cycle, in honor of Nikolaus Otto, who invented it in 1867. The four strokes are illustrated inthe animation. They are: Intake stroke Co...
There's no doubt that Otto's gasoline engine was an invention of genius—but it's now a victim of its own success. With around a billion cars on the planet, the pollution produced by vehicles is a serious—and still growing—problem. The carbon dioxide released when fuels are burned is...
A gas power engine is expected to output work or power through cycle, and the work is expected as much as possible in terms of viewpoints of a unit fuel, a unit volume of an engine, or a unit displaced volume of an engine. Evaluation of gas power engines with thermal efficiency, especi...
As a visual aid points, between which the quantum system operates as the working substance in an Otto cycle, in dynamical configuration space are depicted in a\((\rho , H)\)-coordinate system. FromAtoBthe heat\(\Delta Q_h\)is absorbed from the hot reservoir at temperature\(T_h\)and ...
Analyze and solve the following exercise: An ideal Otto cycle, as shown in the diagram, has a compression ratio of9and a cylinder volume of2liters. At the beginning of the compression process the air is at101.33kPa and20.15°C,...
Gasoline-powered engine: At the heart of the Reitwagen was the groundbreaking, one-cylinder, Otto-cycle engine. This engine, fueled by gasoline, allowed the motorcycle to generate power and propel itself forward. It marked a significant advancement in the use of internal combustion engines for tra...
In this system, a sprocket mounted to the output shaft (i.e., the shaft in the transmission) is connected to a sprocket attached to the rear wheel of the motorcycle by a metal chain. When the transmission turns the smaller front sprocket, power is transmitted along the chain to the ...
