Various efforts of Naval Academy researchers have been directed toward improving the combustion cycle of spark ignition engines. During the past several years they have developed a technique which is based on pressure exchange between two zones in the combustion chamber thereby achieving a heat balanced cycle (NAHBE) which supposedly combines the best characteristics of the Diesel and Otto cycles. In 1977 EPA was requested to test an engine modified to the NAHBE configuration. Due to the required break-in of new engines, the testing was done in early 1978. The tests involved characterizing the fuel economy and emission of the test engines under operating conditions.
