Validation
Acoustic & combustion stability
Combustion noise is a direct acoustic signature of pressure behaviour inside the cylinder. Recording it gives a third, independent view of whether combustion has genuinely changed.
Recorded
Stability measurements
~70%
Fewer combustion pressure spikes recorded on a Mitsubishi Fighter
Smoother
More repeatable cycle-to-cycle pressure behaviour under load
Lower NVH
Reduced combustion harshness carried into cabin and structure
Less fatigue
Fewer pressure excursions reduce cumulative mechanical stress

Why fleets care about stability
Pressure spikes are the mechanism behind a large share of long-run engine wear: bearing loading, head gasket stress, injector and piston crown fatigue. Reducing their frequency reduces the rate at which the asset consumes its own design life.
Stability also shows up operationally as smoother running, lower cabin noise and fewer driver-reported drivability complaints — a small but real factor in driver retention.
