WebFeb 6, 2016 · Download chapter PDF. Otto cycle is one of the thermodynamic cycles used in the internal combustion engines. It comprises (in its ideal version) two isochors (combustion of air-fuel mixture in the engine cylinder and gas exhaust) and two isentropes (compression of fuel-air mixture in the cylinder and expansion of gases in a working … WebOtto Cycle – Otto Engine. In 1876, a German engineer, Nikolaus August Otto, advanced the study of heat engines by building the first working four-stroke engine. A stationary engine using a coal gas-air mixture for fuel. Wilhelm Maybach (1846-1929), one of the most important German engineers, perfected the construction, which was produced in ...

WebSep 10, 2024 · The Otto Cycle that governs the popular four-stroke engine has four separate phases, controlled by precise valve and ignition timing, enacted over two revolutions of the crankshaft: 1) intake, 2) compression, 3) combustion, and 4) exhaust. Each corresponds to a full piston stroke inside the cylinder. WebThe meaning of OTTO CYCLE is a four-stroke cycle for internal-combustion engines of the type used in automobiles wherein the first stroke consists of the suction into the cylinder of the explosive charge (as gas and air), the second stroke consists of the compression, ignition, and explosion of the charge, the third stroke consists of the expansion of the … WebMar 30, 2024 · The Otto cycle is an ideal thermodynamic cycle that requires 4-strokes with a piston: Intake, Compression, Ignition, and Exhaust. The fuel and air mixture is compressed, an electric spark ignites it, the sudden expansion pushes the piston producing a power stroke, and the spring action of the piston pushed the combusted gas away. lincolnton post office nc
