Carnot cycle - Wikipedia
The Carnot cycle is a theoretical ideal thermodynamic cycle proposed by French physicist Nicolas Léonard Sadi Carnot in 1824 and expanded upon by others over the next few decades. It provides an upper limit on the efficiency that any classical thermodynamic engine can achieve during the conversion of heat into work, or conversely, the efficiency of a refrigeration system in creating a
What is Otto Cycle | Complete Explaintion on P-v & T-s Diagram
The Valve Timing Diagram of a 4 Stroke Otto Cycle Engine In this engine, the inlet valve opens during the suction stroke and the exhaust valve opens during the exhaust stroke. The exact movement at which each of the valves opens and closed with reference to the position of piston and crank can be shown graphically in a diagram.
Valve Timing Diagram For IC 2 stroke and 4 Stroke SI and
1. Theoretical valve timing diagram for four-stroke cycle engine. The theoretical valve timing diagram for a four-stroke cycle engine is shown In this diagram, the inlet valve opens at A and the suction takes place from A to B. The crankshaft revolves through 180º and the piston moves from T.D.C. to B.D.C.
Brayton Cycle - Gas Turbine Engine - Nuclear Power
Brayton Cycle – Turbine Engine. In 1872, an American engineer, George Bailey Brayton advanced the study of heat engines by patenting a constant pressure internal combustion engine, initially using vaporized gas but later using liquid fuels such as kerosene. This heat engine is known as “Brayton’s Ready Motor” means, the original Brayton engine used a piston compressor and piston
Stirling engine - Wikipedia
The Stirling engine (or Stirling's air engine as it was known at the time) was invented and patented in 1816. It followed earlier attempts at making an air engine but was probably the first put to practical use when, in 1818, an engine built by Stirling was employed pumping water in a quarry. The main subject of Stirling's original patent was a heat exchanger, which he called an "economiser
What is Otto Cycle - P-V and T-S Diagram Easiest
The entire modern petrol engine works on Otto cycle. It consist of four processes, Two isentropic (reversible adiabatic) processes and two isochoric (constant volume) processes. It has low compression ratio ranges from 7:1 to 10:1. Here we will try to understand this cycle with help of its P-V and T-S diagram.
Four-Stroke Cycle - an overview | ScienceDirect Topics
The actual pressure–volume diagram from an engine operating on a gas or vapor power cycle is called an indicator diagram, 10 and the enclosed area is equal to the net reversible work produced inside the engine.
Otto Cycle - an overview | ScienceDirect Topics
The spark ignition engine is a heat engine which means that is converts heat energy into a mechanical output, or in thermodynamic terms, into work. The actual engine cycle is complex to analyse but it can be simplified or idealised. A thermodynamic schematic of the ideal Otto cycle pressure–volume diagram is shown in Fig. 4.2.
2-Stroke vs 4-Stroke Engine — What’s the Difference
Repairing engine valves is a complicated and expensive procedure, so it is critical that a 4-stroke engine always operate at the correct oil pressure, using the correct type of oil. When moving beyond routine maintenance to long term maintenance and repairs, 2-stroke engines are both easier and cheaper to keep running.
Rankine Cycle - Steam Turbine Cycle
Rankine Cycle – Steam Turbine Cycle. In 1859, a Scottish engineer, William John Macquorn Rankine advanced the study of heat engines by publishing the “Manual of the Steam Engine and Other Prime Movers”ine developed a complete theory of the steam engine and indeed of all heat engines. Together with Rudolf Clausius and William Thomson (Lord Kelvin), he was a contributor to the
