Brazilian Dynamometer Testing Documents Up to 11% Fuel Savings and Reduced Smoke Opacity
How was SuperTech® evaluated by RETIMAQ (Brazil)?
RETIMAQ – Retífica de Máquinas Ltda. (Brazil), a certified engine testing and remanufacturing facility and regional distributor for Volkswagen commercial vehicles, conducted a controlled laboratory dynamometer evaluation of the SUPERTECH® Combustion Optimizer.
The test was carried out on a Mercedes-Benz OM 447 TA diesel engine removed from a long-service commercial truck and fully overhauled prior to testing, ensuring performance comparable to a new engine of the same model.
Evaluation Scope & Method
The evaluation was conducted under repeatable, laboratory-controlled conditions and included:
Dynamometer bench testing using a SCHENCK U1-25 engine dynamometer
Fuel consumption measured gravimetrically using a digital fuel-mass scale
Exhaust smoke opacity measured using a Bosch smoke opacity analyzer
Identical test sequences performed before and after installation of SuperTech®
Multiple engine speeds (1200–2100 RPM) and load conditions (up to 750 N)
A stabilization period allowing SuperTech® to act on the full fuel volume prior to testing
No engine tuning, mechanical changes, or system modifications were made during the evaluation.
What were the observed results?
According to the consolidated test data and final conclusions:
Fuel-consumption reductions exceeding 11% were recorded under normal operating loads (600–750 N @ 1,800 RPM)
Minimum fuel savings of approximately 4% were observed even at low engine loads
Fuel-saving performance increased with higher engine load and RPM, aligning with real-world duty cycles
Clear and repeatable reductions in exhaust smoke opacity were measured across tested RPM ranges
When SuperTech® was removed, smoke opacity levels returned rapidly toward baseline values
The results demonstrated a direct relationship between combustion load and the effectiveness of upstream fuel optimization.
What is the key takeaway for engineers and fleet operators?
The RETIMAQ evaluation provides controlled laboratory evidence that upstream, in-tank combustion-support technology can deliver measurable fuel-consumption reductions and smoke-opacity improvements without modifying engine systems.
