Testing and documentation

Results, with their sources and limits

Each result is shown with its source, test conditions, units and limitations. Different tests are kept separate, and figures from different sources are never combined.

How we classify sources

Original laboratory report

The full report issued by the testing body.

Summary of a laboratory report

Figures quoted from a laboratory report in another document. The original is not published here.

Operator observation

Measurements and observations recorded by the equipment operator, without independent verification.

Projection

An estimate for conditions that were not tested. Not shown on this site.

A testing institution named in a document is not a certification or endorsement. We do not claim any certification for AY BIO MODÜL.

Change values are calculated by us from the cited figures. — = not reported in the source.

¹ The 1,000 km values come from a chart (Figure 3) in the same summary report; its results table lists only the baseline and 11,500 km values.

Limitations

  • One vehicle; the number of repeat runs is not stated.
  • Baseline and final measurements are 11,500 km apart, so vehicle condition, fuel batch and ambient conditions may differ.
  • The summary does not state whether an untreated reference vehicle was tested.
  • The summary does not describe the condition of the vehicle's exhaust aftertreatment at baseline.
  • The summary report describes a 1,000-fold particle reduction; the cited figures correspond to about 893-fold.

Marine generator, vessel operator's report

Operator observation
Equipment
55 kW constant-speed diesel generator on board a vessel
Period
About two months after installation
Method
Litres of fuel delivered to the generator, compared with earlier consumption
Confirmed by
The vessel's chief engineer and captain (written statement, names on file)
Source document
Operator's written report (Turkish), 2026
Supporting material
Engine-room footage of the installation
Reported observations
ObservationPeriodReported by the operator
Fuel consumptionMonth 118 % lower (net), 25 % lower (gross)
Exhaust smokeMonth 2Long-standing soot deposits expelled; smoke then barely visible
Response to sudden loadMonth 2Vibration and near-stalling no longer observed
Operator decisionAfter 2 monthsFit units to five further engines on board

Limitations

  • Not an independent or instrumented test.
  • The report does not define net and gross saving.
  • The report does not describe the baseline period, load profile or fuel quality.
  • The operator states it did not assess the unit's contents or construction.

Academic assessments

Two academics have reviewed the device and the available reports. Their documents interpret existing data and contain no new measurements. Each gives the author's own assessment, not a certification or an endorsement by their university.

Prof. Dr. Afif Sıddıki

Role
Faculty member, Atlas University, Istanbul
Document
AY Drive final report, 24 August 2026 (EN/DE/TR)
Scope
Leads the project design and academic evaluation. The report summarises the TÜBİTAK RUTE test shown above.

Assoc. Prof. Dr. İrem Düzdar

Role
Department of Industrial Engineering, Faculty of Engineering, Düzce University
Document
Assessment ‘AY Drive: Emission transformation and fuel efficiency’, 20 October 2026 (TR)
Scope
Reviews the consumption reports attached to it and concludes that use of the device reduces vehicle fuel consumption. Also discusses the economic and environmental case for the technology.

Patent documentation

US patent application 19/303,452

According to the USPTO Notice of Allowance dated 11 September 2026, US patent application 19/303,452 (‘Emission Reduction’, inventor Yusuf Aberle, filed 19 August 2025) has been allowed. A Notice of Allowance is not a patent grant.

What allowed claim 1 describes

  • A housing located between the fuel filter and the fuel pump
  • Top and bottom covers, each with a grommet for connection to the fuel line
  • A first ceramic element with multiple bores
  • At least one second ceramic element with a contorted through-channel
  • A magnetic zone of three to six rod-shaped magnetic elements and three to six spring coils, arranged alternately and lengthwise in a circle around a central passage
  • The magnetic zone sits between the first ceramic element and the bottom cover

Patent information describes the claimed invention. It is not evidence of the fuel-saving or emissions results presented on this website.

Source: USPTO Notice of Allowance and Fee(s) Due, mailed 11 September 2026, with Notice of Allowability.

Magnetic zone arrangement in claim 1
  • Magnetic element (rod)
  • Spring coil
  • Central passage

Projections

The developer's materials also contain estimated savings for other engine types and ages. These are projections, not measurements, so they are not shown here.
