FAQs — Restoring Efficiency & Reducing Emissions

DPF = Diesel Particulate Filter. It traps soot (solid particles) from diesel exhaust to reduce smoke and particulate emissions. Keeping the DPF healthy helps avoid blockages and expensive replacements. Our cleaning and maintenance approach helps your DPF regenerate effectively so it lasts longer.

EGR = Exhaust Gas Recirculation. It routes a portion of exhaust gas back into the intake to lower combustion temperature and reduce NOx emissions.Our service helps clean the intake path and reduce deposits that cause sticking. (If the mechanism has failed mechanically, replacement may be required.)

Both systems are fitted to modern engines to help meet emissions standards and keep the air cleaner. When they become clogged or sticky due to carbon build-up, drivability and reliability suffer.

The difference depends on the starting condition: the dirtier the engine, the bigger the improvement. Expect smoother idle, better throttle response, reduced smoke, cleaner emissions and improved economy. Think of it like a car wash: a very dirty car looks dramatic afterwards; a clean one looks refreshed.

Carbon build-up is worse on diesels, high-mileage vehicles, cars driven only on short trips, taxis/buses and vehicles that idle a lot.

• Engine warm (ideally after a short drive).
• Space to position our unit near the intake.
• Access to mains power (or a portable generator can be arranged).

1. Arrival checks: leaks, mechanical noises, warning lights and a quick diagnostic scan.
2. Short rev-range exercise to baseline throttle response and idle quality.
3. Consent/work sheet signed; intake prepared and safely sealed after the air filter and MAF.
4. Hydrogen/oxygen flow connected; engine idles for ~45–90 minutes (longer if required).
5. Every ±10 minutes a rev exercise is repeated to accelerate cleaning.
6. Post-clean diagnostics and a final check; intake returned to stock.
7. Where a stationary rev-limiter prevents heat, we may split the clean into two cycles with a brief “spirited” drive between to raise temps.

Hydrogen and oxygen are introduced through the intake. The gases burn quickly and hot, promoting a cleaner combustion event with an oxygen surplus that reacts with carbon deposits. Loosened carbon exits through the exhaust, helping clean the DPF/CAT path as it goes.

On suitable vehicles, EGR passages may also benefit. Very heavy slurry deposits can remain and may require mechanical cleaning if severe.

The cleaning cycle is typically 45–90 minutes plus connection/disconnection and checks. Complex intakes can take longer; very heavy deposits or targeted DPF/EGR/turbo cleaning may require extended time.

As a preventative measure, many owners align it with annual servicing or every 10–15000 km depending on driving style (short urban trips benefit most). You can also book when symptoms appear (rough idle, smoke, sluggishness).

No. The process works on petrol and diesel engines — from passenger cars to bikes, vans, trucks, generators and more.

Yes. It cleans through the intake and across the combustion path. Manifold deposits on some DI designs can be stubborn; we may split the clean into two cycles with a short drive between. Some residual build-up can remain and, if severe, may require walnut blasting or mechanical cleaning.

No. We recommend quality fuels and appropriate service intervals; our process works through the air path.

Before your service is ideal, then change oil/filters so loosened contaminants are captured. If you have existing leaks or faults, fix those first.

Do the clean before tuning. You’ll get the calibration onto a healthier, cleaner baseline.

No. We use hydrogen and oxygen, and the engine’s own combustion heat. No solvents, no oils.

No steam cleaning. The hydrogen does not reconstitute to water in the engine. Because the gas ratios and combustion conditions aren’t stoichiometric for pure water formation, unreacted hydrogen/oxygen remain to aid the cleaning reaction. (See stoichiometric ratio.)

We don’t “pump” them in — the engine’s vacuum draws what it can use. Flow is controlled for engine size and safety.

We have excellent results where there’s still sufficient flow. If a DPF is fully blocked (no flow), mechanical intervention may be required first. Afterwards, a clean engine helps the DPF regenerate properly.

If the issue is caused by carbon contamination (not mechanical failure), cleaning can free sticky vanes or linkages. Mechanical failures still require repair/replacement.

The process cleans catalysts, but if the core is breaking up, cleaning can reveal the failure. In that case, replacement is the correct fix.

The clean works wherever gas can reach. However, for normal road use we do not offer or endorse removal/defeat of emissions equipment. We’re focused on cleaner running and legal compliance.

Cleaning removes carbon that may be masking existing faults. If a component (e.g. failing catalyst, damaged turbo) is only “held together” by deposits, the underlying fault can be revealed. We always perform checks and discuss any concerns before starting.

Hydrogen is non-corrosive; the process targets carbon build-up, not healthy metal surfaces. Aside from the note above (exposing already-failing parts), the procedure is designed to be safe when carried out by trained technicians.
