Change fuel from the molecular level.
NENSOKU PLUS — Liquid Fuel Combustion Accelerator
A single drop transforms combustion, cutting costs and emissions simultaneously.
From Japan, half a century ago, through enzyme technology to molecular dispersion
OUR STORY
Half a century of technology, carried into the next generation.
In the 1970s, a liquid fuel reforming technology called "EX-7" was born in Japan. But as its original developer's owner reached retirement age, continuing development and sales became difficult.
Determined not to let this technology disappear, we entered this field under a newly established company — SDT Co., Ltd. — and took over the technology and the business. We further refined it into an enzyme-free molecular dispersion technology that overcomes the weaknesses of enzyme-based approaches — and today deliver it to the field as NENSOKU PLUS.
Technology validated in Japan, the Americas, and Europe
Global Track Record
Proven on 3 Continents
Born in Japan, this technology has spread worldwide over half a century. "Star Tron" in the USA and "X-BEE" in Europe are sibling brands sharing the same Japanese origin. Under different names in different markets, the same core technology continues to earn trust globally.

Features, mechanism, and how to use NENSOKU PLUS
Improves combustion efficiency at the molecular level, helping lower fuel costs. Verified through JIS standard testing; results vary by fuel type, equipment, and usage conditions.
Cleaner combustion means far less carbon buildup in engines, nozzles, and DPF filters — directly reducing maintenance costs.
Residual carbon (soot) reduction confirmed through JIS standard testing. Helps support environmental compliance and decarbonization goals; actual results depend on fuel type and operating conditions.
No equipment modifications required. Works with any liquid fuel — diesel, gasoline, kerosene, heavy oil. Just add to the tank.
Conventional enzyme-based additives can lose effectiveness with heat or storage time. NENSOKU PLUS uses no enzymes or biological components, so quality stays consistent regardless of temperature or storage conditions.
The science behind NENSOKU PLUS
NENSOKU PLUS disperses fuel hydrocarbon molecules that are clumped into large clusters into finer, more uniform particles.
Finer, more uniform molecules dramatically increase the fuel surface area in contact with oxygen, enabling more thorough mixing.
More complete combustion means less unburned fuel, less carbon residue, and maximum energy extraction from every drop of fuel.
One mechanism delivers three benefits at once: better fuel economy, cleaner exhaust, and reduced equipment stress.

CAUSECloser to complete combustion
Complete combustion extracts maximum energy per unit of fuel. Dramatically reduces fuel costs in high-consumption applications like trucks, vessels, and boilers.
Less unburned fuel means less soot (residual carbon), less NOx, and cleaner exhaust. Enables compliance with increasingly stringent environmental regulations.
Drastically reduced carbon deposits on engines, nozzles, burners, and DPF filters. Lower maintenance costs and extended equipment life.
The vicious cycle caused by fuel molecular state
Fuel clusters agglomerate into uneven, oversized clumps — and are sent to the combustion chamber as-is.
Oversized molecular clusters can't fully contact oxygen. Energy is wasted and escapes as exhaust.
RESULT — Three Consequences
↑ Rising Fuel Costs
↑ NOx & Carbon
↑ Repair Costs
Simple drop-in process — no equipment modifications
Pour NENSOKU PLUS directly into the fuel tank. No special equipment or modifications needed.
The additive mixes uniformly throughout the fuel as the vehicle or equipment operates normally.
Improved combustion begins from the first tank. Effects on fuel economy and emissions are measurable immediately.

Range of fuel types covered
Uses plant-derived enzymes as a catalyst to break down hydrocarbons, sludge, and water in the fuel. The most widely used approach across the industry.
Typical use: Gasoline through heavy oil (varies by product)Uses a surfactant to emulsify water into the fuel, promoting micro-explosions in the combustion chamber.
Typical use: Industrial furnaces & boilersUses a metal compound, such as magnesium hydride, as a catalyst — its hydrogen acts as an ignition point to even out combustion.
Typical use: Marine & heavy-oil applicationsDisperses the fuel molecules themselves evenly and finely, without relying on enzymes or metal catalysts. Made from kerosene only, with no extra additives.
Typical use: All fuel types in one productFrequently asked questions
Yes. NENSOKU PLUS works with all liquid fuels — diesel, gasoline, kerosene, and heavy oil. It can be used in engines, boilers, burners, and generators.
No modifications are needed. Simply pour the additive into the fuel tank at the specified dilution ratio. Works with existing equipment from day one.
Effects typically begin from the first tank of treated fuel. The improvement in combustion efficiency is measurable immediately. Continued use also delivers cleaning benefits as carbon deposits are gradually reduced.
Yes. NENSOKU PLUS is based on technology with over 50 years of track record worldwide, including use in transcontinental railways and heavy marine applications. It has no adverse effects on engines or equipment.
The product has been certified through Japan's JIS standard testing, holds US EPA certification, and has been sold commercially across Europe. The scientific basis is well-established internationally.

"I was skeptical at first, but after continued use, I noticed our refueling intervals started to change. I can't say exactly why, but something feels different."
※ Individual experience. Results may vary.
"Our facility staff mentioned that the boiler startup felt different, which is how we first noticed. It's a subjective impression, but we've kept using it since."
※ Individual experience. Results may vary.
"I use it in my kerosene fan heater. I feel like the unpleasant smell has become less noticeable, though it may just be my impression. I've kept repurchasing it either way."
