Air Plains Services, of Wellington, Kan., and Petersen Aviation Inc., of Minden, Neb., have agreed to partner on an Anti-Detonation Injection System (ADI), which will allow GA engines to run on low-octane fuels.
In the early 1990s Petersen Aviation certified ADI Systems on Cessna 188s, 210s and Barons, which allowed operation of these aircraft using 91 octane autofuel when the anti-detonation injection system is installed.
With the rising concern on the elimination of avgas, the two companies are combining resources to rediscover the answer that general aviation has been waiting for, company officials said.
Petersen’s ADI System was developed to allow high compression engines to run on low octane fuels safely. Air Plains Services intends to develop additional Supplemental Type Certificates for ADI, which will enable the installation of the system components on the aircraft and provide the owner with more fuel choices.
Anti-Detonant Injection, also know as Water Injection, is not a new technology or invention. As a matter of fact, it has been used in aircraft prior to World War II, company officials said. During the war water injection was used to prevent detonation while developing significant additional power. ADI can also be used to develop rated power on a lower octane fuel. The installation of a modernized ADI system into the general aviation fleet will provide the user with a significant amount of flexibility.
