It is widely used in diesel engines. Diesel cycle is similar to Otto cycle except in the fact that it has one constant pressure process instead of a constant volume process (in Otto cycle). Diesel cycle can be understood well [...]

Derivation of mean effective pressure of Otto cycle http://mechteacher.com/otto-cycle-mean-effective-pressure-derivation/ http://mechteacher.com/otto-cycle-mean-effective-pressure-derivation/#comments Fri, 07 Dec 2012 13:02:24 +0000 http://mechteacher.com/?p=520 In my previous articles, I gave an introduction to Otto cycle and derived the air-standard efficiency of Otto cycle. In this article, I will derive the mean effective pressure (m.e.p) of Otto cycle. What is Mean Effective Pressure? Mean effective pressure is the ratio of work done (W) during the working stroke(s) of a cycle [...]

Otto Cycle – Processes with p-V and T-s Diagrams http://mechteacher.com/otto-cycle/ http://mechteacher.com/otto-cycle/#comments Wed, 03 Oct 2012 11:11:42 +0000 http://mechteacher.com/?p=155 Otto cycle is a gas power cycle that is used in spark-ignition internal combustion engines (modern petrol engines). This cycle was introduced by Dr. Nikolaus August Otto, a German Engineer. An Otto cycle consists of four processes: Two isentropic (reversible adiabatic) processes Two isochoric (constant volume) processes These processes can be easily understood if we [...]

Introduction to Gas Power Cycles http://mechteacher.com/introduction-to-gas-power-cycles/ http://mechteacher.com/introduction-to-gas-power-cycles/#comments Wed, 25 Jul 2012 07:35:00 +0000 http://www.mechteacher.com/?p=6 A thermodynamic cycle is a sequence or series of processes performed on a system, that eventually returns the system to its original state. Gas power cycles are thermodynamic cycles, which use air, as the working fluid. A gas power cycle may consist of heat transfer, work transfer, pressure variations, temperature variations, volume variations and entropy [...]
