• Otto_cycle abstract "An Otto cycle is an idealized thermodynamic cycle which describes the functioning of a typical spark ignition reciprocating piston engine, the thermodynamic cycle most commonly found in automobile engines.The Otto cycle is constructed out of:Top and bottom of the loop: a pair of quasi-parallel and isentropic processes (frictionless, adiabatic reversible).Left and right sides of the loop: a pair of parallel isochoric processes (constant volume).The isentropic processes of compression and expansion implies no loss of mechanical energy due to friction and no transfer of heat into or out of the system during those processes, hence the cylinder, and piston are assumed impermeable to heat during those processes. Heat flows into the loop through the left pressurizing process and some of it flows back out through the right depressurizing process, and the difference between the heat added and heat removed is equal to the net mechanical work generated.The processes are described by:Process 0-1 a mass of air is drawn into piston/cylinder arrangement at constant pressure.Process 1-2 is an isentropic and adiabatic compression of the air as the piston moves from bottom dead centre (BDC) to top dead centre (TDC).Process 2-3 is a constant-volume heat transfer to the working gas from an external source while the piston is at top dead centre. This process is intended to represent the ignition of the fuel-air mixture and the subsequent rapid burning.Process 3-4 is an isentropic expansion (power stroke).Process 4-1 completes the cycle by a constant-volume process in which heat is rejected from the air while the piston is at bottom dead centre.Process 1-0 the mass of air is released to the atmosphere in a constant pressure process.The Otto cycle consists of isentropic compression, heat addition at constant volume, isentropic expansion, and rejection of heat at constant volume. In the case of a four-stroke Otto cycle, technically there are two additional processes: one for the exhaust of waste heat and combustion products at constant pressure (isobaric), and one for the intake of cool oxygen-rich air also at constant pressure; however, these are often omitted in a simplified analysis. Even though those two processes are critical to the functioning of a real engine, wherein the details of heat transfer and combustion chemistry are relevant, for the simplified analysis of the thermodynamic cycle, it is more convenient to assume that all of the waste-heat is removed during a single volume change. A P-V animation of the Otto cycle is very useful in the analysis of the entire process.".
