Engine builders can take advantage of the higher octane to raise the compression ratio, which improves
the thermodynamic efficiency of an engine.
Not exact matches
As a result — regardless
of load or
engine speed — the valves always strike the perfect balance between minimal friction and high
thermodynamic efficiency.
With an octane rating
of up to 130, NG has the potential to optimize an
engine's
thermodynamic efficiency through a high compression ratio.
The range
of measures here is quite great; for example,
engine efficiency can be improved by three different kinds
of measures, increasing
thermodynamic efficiency, reducing frictional losses and reducing pumping losses (these losses are the energy needed to pump air and fuel into the cylinders and push out the exhaust) and each kind
of measure can be addressed by a great number
of design, material and technology changes.
The
thermodynamic efficiency and power
of the Hadley system, considered as a heat
engine, is estimated at 200 terawatts.
