Greater fuel economy results from reduced throttling losses when using fewer cylinders under light load conditions. Several approaches were considered, with the releasable fulcrum proving to be the most effective concept. Subsequent engineering efforts refined the design to develop a simple bolt-on device which would meet specific performance requirements.
