Internal Combustion Engines

5 self-contained study topics — notes, diagrams, formulas, and worked examples for exams and GATE.

Topics

Engine Cycles
Engine cycle analysis relates compression ratio and heat addition mode to efficiency and output.
$Compression ratio r = \frac{V_{max}}{V_{min}}$
Fuel Injection Systems
Fuel injection meters fuel mass precisely using pressure, injector flow, and ECU timing.
Combustion and Emissions
Combustion quality controls power, while temperature and oxygen availability control regulated emissions.
Engine Performance Testing
Performance testing converts torque, speed, fuel, and airflow measurements into efficiency and economy metrics.
Alternative Fuels
Alternative fuels trade storage, combustion behavior, and life-cycle emissions against conventional fuels.
