Subject field(s)
  • Transformation of Momentum (Mechanical Components)
  • Engines (Motor Vehicles)
CONT

When a piston in an engine is pushed up into its cylinder, the upward movement traps the mixture of air and fuel above it and compresses it to one-eighth or one-ninth of its original volume. This puts the molecules closer together, so they hit the piston head far more often. Thus, the pressure goes up.

Campo(s) temático(s)
  • Transformación de la cantidad de movimiento (Componentes mecánicos)
  • Motores (Vehículos automotores)
CONT

La forma del émbolo y la de aplicar la fuerza del gas a la biela a través del perno del émbolo dependen además mucho de la forma de la cámara de combustión y por lo tanto de la forma de la cabeza del émbolo, y del sistema de combustión empleado y sus presiones máximas de combustión.
