  • During the instroke of the piston, the cylinder fills with the air-fuel mixture.

Examples

  • Engineers measured the pressure at both the instroke and outstroke for optimal performance.

  • Wear and tear are most noticeable after repeated instrokes in high-speed engines.

  • The instroke is essential.

  • During the instroke, air enters.

  • During the instroke of the piston, the cylinder fills with the air-fuel mixture.

Morphology

instroke = stroke (semi-transparent) = in + stroke

The parts suggest an inward stroke, but the exact engine-specific meaning is technical rather than fully predictable for a general learner. [Postprocessing: moved 'in' from base_words to prefix]

Etymology

Instroke joins the prefix in- ('in') and the common word stroke ('a movement'), so it names the piston’s 'in' movement during a stroke; that's why engineers call this particular part of the engine motion the instroke.
