Simply drop the D-Ball into your diesel tank through the filler cap — no tools, no modifications. Make sure to avoid placing it near the fuel level sensor float (if your equipment has one) to prevent interference with fuel gauge readings. That's it. The ceramic technology starts working immediately and requires zero maintenance for up to 10 years.

The D-Ball is designed for small diesel engines with tank capacities up to 20 liters. This includes equipment like small generators, lawnmowers, compact tractors, scooters, and small marine auxiliaries. If your tank is larger (e.g., 60L or 100L+), you'll need a different model — reach out and we'll help you find the right fit.

Yes. The D-Ball is compatible with standard diesel (ULSD), biodiesel blends (B5, B20, etc.), and most diesel fuel types. The ceramic technology works by breaking down fuel molecule clusters, so it adapts to various diesel formulations. Performance may vary slightly depending on fuel quality and blend ratio.

The D-Ball contains Greentech's patented ceramic formula that emits far-infrared energy to reduce fuel viscosity and improve atomization. It's a solid, sealed unit — nothing dissolves, leaks, or contaminates your fuel. It's non-toxic, non-reactive, and has been certified by TÜV Rheinland, , and DOTARS. Safe for your engine, safe for the environment.

The D-Ball has a service life of approximately 10 years under normal use. No maintenance, no refills, no replacement parts. Once installed, it keeps working silently in your tank. After a decade, you can replace it with a new unit if you want to continue the benefits.

Real-world results vary by equipment age, condition, and usage patterns, but customers typically report 5–15% fuel efficiency improvement and noticeably cleaner exhaust (lower smoke, reduced odor). Fleet tests have shown emission reductions of 25–85% in HC, CO, and NOx. Your mileage may vary — older, poorly maintained engines tend to see bigger gains.

No. Greentech is a B2B product line, and we do not provide free trials, pilot programs, or risk-free samples. The way customers verify performance is through an initial commercial order. If you're a fleet operator, distributor, or equipment dealer and want to test at scale, contact us with your fleet size and timeline — we'll work out a commercial purchase that fits your validation process.

Absolutely. We work with fleet operators, authorized distributors, and commercial buyers worldwide.

Leave your contact info and our team (Rita) will follow up with a formal quote.

Great to hear! We evaluate distributor partnerships based on territory availability. First, tell us which countries or regions you're targeting (please list all of them). We'll check whether those areas already have active distributors — we don't overlap territories or offer the same pricing structure where representation exists. Once we confirm availability, we'll discuss terms. Please provide your company details, target regions, and expected first-order volume to get started.

The D-Ball and Greentech's ceramic technology are backed by TÜV Rheinland (Germany), Taiwan, DOTARS/Orbital (Australia ADR-79/81), and have been tested by fleets and government agencies in India (KSRTC), UAE (IFFCO), Portugal, Saudi Arabia, Qatar, Ethiopia, Hong Kong PolyU, and Vietnam. All reports and certifications are from commercial deployments or official government fleet trials — not lab-only tests.

D-Ball is built for small diesel engines with fuel tanks up to 20 liters — think compact generators, agricultural equipment, small marine engines, or diesel scooters. If your tank is larger (around 100L), you'll want our D10/D11 series instead.

No. D-Ball is formulated specifically for diesel fuel. For gasoline engines under 20L, use our G-Ball. For LPG/CNG systems, we offer a separate Gas Fuel Saver that's installed inline on the gas pipe — contact us for engineering specs.

D-Ball contains a proprietary ceramic compound that emits far-infrared energy to break down diesel molecule clusters and reduce viscosity. It's completely non-toxic, non-combustible, and chemically inert — it doesn't dissolve, leak, or react with fuel. Certified by TÜV Rheinland, , and DOTARS Australia.

Real-world results vary by engine condition, load, and maintenance history — typically 5–15% improvement in fuel efficiency, with emissions reductions up to 85% in HC, CO, and NOx. Newer, well-maintained engines see more consistent gains. Performance is cumulative and improves over the first few weeks of use.

None. Once installed, the ceramic core works continuously for up to 10 years with zero upkeep. No cleaning, no recharging, no consumables. Just drop it in and forget it.

Absolutely. Greentech is a B2B brand — we work with fleet operators, equipment dealers, and authorized distributors. For volume pricing or distributor inquiries, contact us with your company details, order quantity, and region. We do not offer free trials or pilots; all testing is done through commercial orders.

We ship globally from Taiwan. Lead time depends on order size and destination — typically 2–4 weeks for standard commercial orders. Shipping and terms are finalized during the quotation process. For urgent or large deployments, reach out to our team directly.

D-Ball is a patented ceramic-based fuel enhancer designed for small diesel engines with tanks under 20 liters. You simply drop it into your fuel tank—no installation required. The ceramic core emits far-infrared waves that break down diesel molecule clusters, reducing viscosity and creating finer fuel atomization. This means more complete combustion, better fuel efficiency, and lower emissions. It's a non-invasive solution that works passively for up to 10 years without any maintenance.

D-Ball is perfect for compact diesel engines with fuel tanks 20 liters or smaller. Common applications include diesel scooters, small generators, portable pumps, compact construction equipment, lawn and garden machinery, and small agricultural tools. If your equipment runs on diesel and has a tank under 20L, D-Ball is designed for you. For larger tanks (60–100L and up), we recommend our D10/D11 or D20/D21 models instead.

Installation is simple: open your fuel tank cap, drop the D-Ball directly into the tank, and close the cap. That's it. The only thing to watch for is avoiding your fuel level sensor or float gauge—placing D-Ball away from the sensor ensures your fuel gauge reads correctly. For best results, we recommend having a technician or mechanic handle installation if you're unsure about your tank's internal layout.

Absolutely safe. The D-Ball uses a proprietary ceramic formula developed in Taiwan under our Molecule Enhance Technology (MET). The ceramic material is inert, non-toxic, and designed specifically for long-term fuel tank exposure. It doesn't dissolve, corrode, or react chemically with diesel fuel. The device is certified by TÜV Rheinland, Taiwan, and Australia's DOTARS ADR-79/81 standards. It poses no risk to your engine, fuel system, or the environment.

Results vary based on equipment age, operating conditions, and maintenance history, but typical improvements include 5–15% fuel savings and significant reductions in harmful emissions—HC, CO, and NOx can drop by 25–85% depending on baseline engine condition. You'll notice smoother engine performance, less smoke, and over time, lower fuel costs. D-Ball has been validated in commercial fleets and government testing (like India's KSRTC and UAE's IFFCO), so real-world performance is well-documented.

D-Ball lasts up to 10 years with zero maintenance. There's nothing to replace, refill, or service. Once installed, it works continuously as long as it remains in the tank. This makes it an incredibly low-effort, long-term investment for improving fuel efficiency and emissions.
