Turbines' rotational operation ensured a smoother power delivery than vibrating piston engines. With fewer moving parts, turbines were generally smaller and lighter. This was a significant shift ...

We’re introduced to the traditional two-stroke diesel engine as thermally efficient but not smooth-running, and then the gas turbine as smooth but much more inefficient. The free piston engine ...

Technical difficulties were never fully overcome, the increasing cost of fuel made gas turbine cars uneconomic to run, and meanwhile by the 1960s the piston engine had improved immeasurably over ...
