The proof must be immediately visible
NTROPYX is a combustion catalyst.
It has one function: to bring each combustion cycle as close as possible to its theoretical efficiency — near-perfect combustion, in which the fuel’s energy is fully released rather than dissipated as losses, residue and smoke.
NTROPYX brings combustion closer to its useful efficiency, without adding a conventional additive and without modifying the engine. In documented cases, this translates into 8 to 12% less fuel, cleaner combustion, less fouling and lighter maintenance.
It acts on the reaction, never on the substance: laboratory chemical analyses detect no transformation of the treated fuel.
Everything rests on catalytic action of extreme precision, active at less than 0.02 ppm.
Official tests, conducted to European and Chinese standards, measure higher octane and cetane numbers, lower consumption, and a reduction in both fine particles and pollutant emissions.
A technology proven over fifteen years, commercialised for more than seven years, it is used across all fuels — road, marine, industry, generator sets — without any engine modification or change of equipment.
The result for the operator is direct: lower fuel costs, cleaner combustion, less engine fouling, lighter maintenance, longer service life.
Combustion, taken to its limit.Not a better fuel. The same fuel, burned as completely as chemistry allows.
The fuel stays the same. The combustion doesn’t.Active below 0.02 ppm — beneath what laboratory analysis can detect, inside the reaction where energy is released.
8 to 12% less fuel. Up to 70% fewer emissions.No engine modification. No equipment change. No downtime.
Fifteen years in service. Three billion road kilometres.Engineered in Switzerland. Verified under CNAS, ILAC-MRA and CMA.
One principle, fuels to be qualified.
-
White bottle. For road and standard fuels.
-
Brown and black bottles. For marine use.
-
Dosing. The logic stays the same; dosing is worked out per fuel and per operation.
-
Start with the fuel. End with the measurement. The right order is deliberately simple: fuel, bottle, dosing, proof, economic scenario.
The science, one page
Combustion explains the gain.
The point is not to rename the fuel. The point is to promote more complete oxidation, so that less energy leaves the engine as waste.

Technical evidence
Measurement decides before ROI.
Two engines on the bench, one vessel at sea. A laboratory measured NTROPYX in March 2026 on a road diesel engine and a marine diesel engine. On board the M/V KAYRA, measurements were taken on two generator sets.
NTROPYX app
A calculation that prepares the conversation in the field.
ROI, dosing and road testing are brought together to prepare a decision a fleet team can act on.
Decision path
Go from a fuel bill to a quantified decision.
A serious decision starts with only a few inputs: annual litres, fuel, available evidence, modelled savings and deployment scope.
Eight contexts to qualify
Each sector speaks its own language: volume, fuel, relevant evidence and purchasing logic.
Send an actionable request.
Once the scope is clear, the next step is not a pitch: it is a well-defined request.
Four inputs for a serious answer.
