text: The diesel engine has the highest thermal efficiency of any standard internal or external combustion engine due to its very high compression ratio.
text: The intake compression ratio, which can be as high as 32:1 at Mach 3, adds to that of the engine compressor to give the Overall pressure ratio and η t h {\displaystyle \eta _{th}} for the Thermodynamic cycle.
text: With a "spinner," the bottom-end must be up to the task (that means premium parts, dead-nuts machining, and meticulous assembly), the compression ratio should be as high as practical for the available fuel, the cam needs to have sufficient lift and duration, the valvetrain must be stable at rpm, and the cylinder heads must be capable of flowing sufficient air at high rpm-or the engine won't live long enough to reach its full theoretical power potential.
