Effect of volatility on air-fuel ratio distribution and torque output of a carbureted light aircraft piston engine. Final report, May 1981-September 1982
A comprehensive sea - level - static test cell data collection and evaluation effort to review operational characteristics of a carbureted light aircraft piston engine as related to fuel volatility and air fuel ratio distribution to cylinders. Sea - level - static test cell engine operations were conducted utilizing an AVCO Lycoming 0-320 engine connected to an eddy current dynamometer which facilitated data collection under various engine load conditions. Test cell instrumentation was utilized to obtain operational data (temperatures, pressures, flow rates, torque, horsepower, exhaust emissions, etc.) from idle through cruise to maximum power with fuel grades having reid vapor pressure of 6.7, 11.7 and 14.0. The primary purpose of test cell engine operation was to observe real time performance characteristics associated with automotive grade fuel utilized by piston powered light general aviation aircraft. In fulfillment of this task, baseline engine operations were established with 100LL aviation grade fuel followed by two blends of automotive grade fuel.
