Exploratory Program to Evaluate a Deep Pocket Rotor Configuration in the Stratified Charge Rotating Combustion Engine Using the RC1-90 Test Rig.
Abstract
Testing of the stratified charge rotating combustion engine was continued. The objective of the current work was to evaluate the performance of a modified rotor assembly having a new deep narrow combustion chamber pocket shape and compare it to previous test data from earlier rotor configurations using the same basic spark plug/fuel injector configuration. Test results showed an improvement in the light load - lean mixture operation, both in fuel economy and leanability. At rich mixture - high power operation the new pocket shape gave considerably lower SFC's than the original standard pocket rotor but gave slightly higher SFC's than the 'Beetle' pocket rotor. Differences in the performance is related to variations in the pocket shapes. Continued development is recommended with emphasis placed upon improving the lean mixture - light load operability.
