As part of a product improvement program, an extensive spark-ignited, turbocharged, natural gas engine exhaust valve test program was conducted using laboratory and field engines. Program objectives were to identify a valve and seat insert combination that increased mean time between overhauls (MTBO) while reducing the risk of premature valve cracking and failure. Following a thorough design review, a large number of valve and seat insert configurations were tested in a popular 900 RPM, 166 BHP (0.123 Mw) per cylinder industrial gas engine series. Material, head geometry, seat angle and other parameters were compared. Careful in-place measurements and post-test inspections compared various configurations and identified optimal exhaust valving for deployment in new units and upgrades of existing engines.
