Study Notes
Combustion Engineering
- The subject ME 3213 is about Combustion Engineering, which is part of the Mechanical Engineering program at Romblon State University.
The Ideal Cycle
- The ideal cycle is a simplified model of the combustion process, assuming ideal conditions and ignoring some complexities.
- It takes into account only the first two strokes and assumes the gases are air only, with heat being added and removed from external sources.
The Four Strokes of an Engine
- The four strokes of an engine are:
- Intake stroke: piston moves down, pulling in air-fuel mixture
- Compression stroke: piston moves up, compressing the mixture
- Power stroke: spark plug ignites the mixture, pushing piston down
- Exhaust stroke: piston moves up, pushing out exhaust gases
The Otto Cycle
- The Otto cycle is the ideal cycle for internal combustion engines, using gasoline and a spark igniter to generate thermal energy.
- It consists of four strokes: intake, compression, power, and exhaust.
- The Otto cycle is a thermodynamic cycle that generates motion from thermal energy.
Processes in the Otto Cycle
- Isentropic compression: first stroke, from state 1 to 2
- Isochoric heat addition: between strokes 1 and 2, at constant volume
- Isentropic expansion: second stroke, from state 3 to 4
- Isochoric heat rejection: between strokes 2 and 3, at constant volume
