Technology

An engineering description, and how we measure. Nothing here is a claim about your engine — we make those only after we have measured it, under the protocol below.

What the retrofit is

An exhaust treatment retrofit for compression-ignition engines: an aftertreatment stage fitted to the exhaust line, sized to the engine’s power band and duty cycle. It treats the exhaust stream after combustion. It does not modify the engine’s fuelling, timing, or internals, and it is not a certified emissions-control device unless a certificate has been issued for that exact build.

How it is fitted

We survey the installation first — the engine, the exhaust routing, the available space, and the duty cycle the engine actually runs. The retrofit is then specified to that survey. A standby generator that runs a monthly test and a machine that runs a full shift are different installations even with the same engine, and the survey is what tells them apart.

The measurement protocol

We do not publish a headline figure and ask you to assume it applies to your engine. Instead we measure on your own engine, before and after, under an agreed protocol:

1. Baseline. We record the engine, its rating, and the load points we will test at, then measure the exhaust under those load points with a named analyser, on a recorded date.
2. Retrofit. We fit the treatment stage specified from the survey.
3. Repeat. We measure again at the same load points with the same analyser, and record the date.

Every measurement we report carries the engine, the load, the analyser, and the date it was taken under. A figure without those four things is not a measurement and should not be read as one. The supporting documents live in the proof locker; supplier material there is labelled as the manufacturer’s own.

What we do not claim

We do not state a guaranteed outcome for your engine before we have measured it, and we do not describe the retrofit as certifying your plant’s emissions. What we offer is a survey, a before-and-after measurement, and a conversation about what the numbers mean for your site.
