Aircraft engines are running on full load for almost all the time, with added load during take off. Car engines are not, a modern car engine would blow up running under the same load patterns then aircraft engines. And sincr ICE engines are dying bread when it comes to aircraft, why bother if the current ones work perfectly fine for what they are supposed to do?

  Wouldn't surprise me if aviation engines would move to turbines (see TurbAero and Turbotech for turboprops designed for the GA end of the market), and electric for short range. Leaving little if any space for piston engines. Though of course existing planes aren't going away for a long time.

    Turbines are internal combustion engines. But I guess the comment I originally replied to meant non-turbine ICE only?

        Obviously claiming turbine powered aircraft are a dying breed would be outlandish. I wrote ICEs, and meant piston powered aircraft... my bad...

        No worries. I thought you were looking into some far future of electric aircraft? At the moment, that seems outlandish, but also not totally implausible.

        Short distance electrical aircraft can and will will soon enough, by aerospace standards so in the next decade. Long distance, what is currently served by exisiting commercial airliners, batteries are by far too heavy for now. Green fuel alternatives will happen sooner I guess. Aerospace is changing fast currebtly, I haven't seen anything like it in the last 20-30 years. Interesting times in deed.

  Modern aircraft use turbines, either as turboprops or jet engines. Those burn kerosene.

And yet many light aircraft are powered by very simply-adapted car engines.

  And those are following totally different certification requirements.
