Maintain to how the engine performs, not to a clock.

Interval schedules overservice healthy engines and miss the ones drifting off baseline. EBM™ measures combustion and tells your shop where the opportunity actually is.

Answer first

How does emissions-based maintenance diagnose a diesel engine from its exhaust?

Emissions-Based Maintenance measures the chemistry a diesel engine leaves in its exhaust and compares it against the engine's own EPA-certified baseline. When an engine runs as the manufacturer designed, it leaves a distinct emissions profile; when it drifts out of tune, the chemistry shifts. The size of that shift is quantified as recoverable fuel and a specific repair.

Tier-independent
EBM™ reads upstream of aftertreatment, so the method holds from Tier 2 iron to Tier 4 final.
Both directions
High and low deviations are both meaningful. The full picture of combustion, not one side of it.
OEM-agnostic
32,000+ EPA-certified engines, 200+ manufacturers, model years 1996 to 2027.
Emissions-Based Maintenance™ Methodology

The Diagnostic & Repair Flywheel

Every verified repair feeds the next test. The loop keeps turning for as long as the engine runs, so the benefit carries across the entire life of the unit.

Skinner™ AI

The judgment of one master technician, available to every engine.

Skinner™ does not replace the technician. It scales a way of reading engines that took forty years to earn, and applies it consistently across the whole fleet, with a recovery target held to 5 to 7% of fuel.

How the method works, answered.

How is combustion efficiency measured from exhaust?

When an engine runs as the manufacturer designed, it leaves a distinct emissions profile; when it drifts out of tune, the chemistry shifts. EBM™ measures that chemistry against the engine's own EPA-certified baseline, and the size of the shift is quantified as recoverable fuel and a specific repair.

What is Skinner™ AI?

The diagnostic intelligence inside the platform: AI-powered diagnostics trained by 40+ years of a master diesel technician and a comprehensive diagnostic protocol, built to think like Skinner™ and diagnose more engines than one expert ever could.

How is this different from a fault code?

An OEM fault code fires only after a problem crosses a threshold the engine controller watches. EBM™ reads combustion chemistry directly, so it catches efficiency drift well before any code triggers, and recommends the correction early.
