Innovation and the Development of Flight
With such fuels and water-alcohol injection, the rated War Emergency Power of
the P-47 Thunderbolt increased from 2,200 to 2,600 horsepower. The Ethyl
Corporation identified triptane as potentially one of the most powerful antiknock
fuels.
A new motor fuel, triptane, will raise engine power fifty percent over that obtained
with 100-octane gasoline. Possessing remarkable anti-knock properties, the
hydrocarbon will permit higher compression ratios in new engines, with resulting
...

One of the new high-octane blending agents is triptane, known to the chemist as
2.2.3 trimethyl butane. Triptane has the highest anti-knock quality of any of the
alkylate-type fuels yet developed. It is far better than the “perfect” iso-octane of a ...
