Calibration of Pratt & Whitney R-1830-86 Engine
Abstract
Tests were conducted on a Pratt & Whitney R-1830-86 engine equipped with a PD12E2-2 carburetor to determine the performance characteristics and to evaluate operation when using fuel having an aromatic content of approximately 20%. Comparative mixture control runs extending over the complete cruise range and including normal and take-off conditions indicated that best economy mixture results averaged 1% richer when using aromatic fuel. The mixture temperatures, when using aromatic type fuel, were found to be slightly less, and the Bendix PD12E2 carburetor metered approximately 2.5% richer at the air flows near and above rated, but a negligible amount at air flows in the cruising range. Generally, no difference in engine operation, including smoothness and acceleration, was noticeable. No signs of detonation were present when using either fuel.
