Diesel Efficiency & Decarbonization Solution
A comprehensive five-pillar approach delivering 15%–20% fuel savings for diesel fleets
Solentis Labs presents a multi-dimensional approach to diesel engine efficiency enhancement that integrates five synergistic technologies targeting lubrication, air intake, fuel chemistry, thermal management, and driver behavior. The combined system is projected to deliver 15% to 20% fuel savings with corresponding reductions in carbon emissions.
Nano-Friction Reduction
Lubrication System Optimization
The Technology: An advanced nanoscale lubricant additive is introduced to the engine oil. The additive deposits a nanofilm of high-performance solid lubricant (e.g., nanodiamonds or tungsten disulfide) onto the cylinder wall and piston ring friction surfaces.
The Mechanism: This film converts boundary sliding friction into lower-resistance rolling friction during operation, significantly reducing surface wear and operating temperatures. The nanofilm fills microscopic surface asperities on the cylinder walls, creating a smoother bearing surface.
The Benefit: Reduced mechanical friction leads to smoother engine operation, lower operating temperatures, and a direct reduction in parasitic drag. Studies on analogous nano-additives have demonstrated fuel savings of up to 12%–15% under controlled test conditions.
Projected saving: 12%–15% fuel reduction | Smoother operation, lower temperatures, reduced mechanical friction
Vortex-Induced Airflow
Intake System Optimization
The Technology: A vortex-generating static mixer constructed of corrosion-resistant titanium or stainless steel is installed in the engine air intake duct.
The Mechanism: The device imparts a high-velocity swirl to the incoming charge air. In a diesel engine, this enhanced swirl improves air-fuel mixing during the compression stroke and injection event. Superior air entrainment ensures better oxygen distribution around each fuel droplet, promoting more complete chemical reaction during combustion.
The Benefit: Enhanced charge motion results in a faster, more complete combustion event. This increases peak effective cylinder pressure per mass of fuel injected, yielding greater brake thermal efficiency. Optimized charge motion has been shown to reduce brake specific fuel consumption (BSFC) by approximately 2%–5% in engine dynamometer testing.
Projected saving: 2%–5% fuel reduction | More complete combustion, greater power from same fuel volume
Cetane Enhancement
Fuel System Optimization
The Technology: A high-performance fuel-borne catalyst and cetane improver, such as 2-ethylhexyl nitrate (2-EHN), is dosed into the diesel fuel.
The Mechanism: Cetane improvers shorten the fuel ignition delay—the time interval between the start of injection and the onset of combustion. A shorter, more controlled ignition delay reduces premixed combustion spike, produces smoother pressure rise rates, and lowers emissions of particulate matter (PM) and unburned hydrocarbons (HC). The fuel begins burning at the optimal crank angle for thermal efficiency.
The Benefit: By optimizing combustion phasing and kinetics, this additive ensures more of the fuel chemical energy is converted into indicated expansion work rather than lost as waste heat in the exhaust or as unburned species. Fleet trials and laboratory tests of similar fuel conditioners have demonstrated net fuel economy gains ranging from 2% to 10%.
Projected saving: 2%–10% fuel reduction | More energy converted to useful work, cleaner exhaust
OBD Telematics & AI Coach
Driver Behavior Optimization
The Technology: An intelligent telematics unit connects to the vehicle diagnostic port (OBD-II or J1939), interfacing directly with the Engine Control Module (ECM).
The Mechanism: The device continuously monitors ECM data—including engine speed (RPM), accelerator pedal position, gear ratio, and instantaneous fuel rate. Proprietary algorithms analyze driver behavior in real time to identify fuel-inefficient operating modes such as harsh acceleration, lugging, improper shift points, and excessive idling. The system provides immediate audio/visual driver coaching.
The Benefit: Driver behavior is arguably the single largest variable in on-road fuel consumption. Studies consistently show that aggressive driving can increase fuel consumption by 20%–50%. By providing actionable feedback, this system helps operators achieve a 10%–25% reduction in fuel usage. Importantly, our system is designed to guide driver behavior rather than to modify ECU calibration, ensuring safety and regulatory compliance.
Projected saving: 10%–25% fuel reduction | Guides behavior, not ECU calibration — safe, compliant, effective
Thermal Management
Maintaining the Ideal Operating Window
The Technology: A system ensuring the engine coolant temperature is maintained within its optimal range of 75°C–90°C (167°F–194°F). This is achieved through the inspection, maintenance, and potential upgrade of existing thermostatic and cooling fan controls.
The Mechanism: An engine running below target operating temperature suffers increased heat transfer losses through the cylinder walls. This quenches the combustion boundary layer, retards flame propagation, and degrades overall thermal efficiency while increasing oil viscosity drag. This process ensures the engine reaches and holds its sweet spot for thermal efficiency using properly functioning OEM cooling components.
The Benefit: Maintaining optimal coolant temperatures—rather than allowing the engine to run cold—yields fuel savings of 3%–7%. No aftermarket chemical coolant additives are required; the improvement relies purely on sound thermodynamic principles.
Projected saving: 3%–7% fuel reduction | Optimal thermal efficiency window prevents heat loss
Integrated System Services
Installation & Maintenance Requirements
Professional Installation: Our technicians provide complete turn-key installation for all five systems. Proper installation and adherence to maintenance protocols are critical to achieving and sustaining the projected 15%–20% overall fuel savings.
Installation Requirements:
- Engine Oil Specification: Must use a stable, single-brand engine oil that meets the manufacturer's specifications. Do not mix oil brands.
- Engine Flush: Prior to refilling with fresh oil, the crankcase must undergo a thorough flush using an approved flushing agent to clear sludge and deposits.
- Hot Oil Fill and Run-In: Fresh oil and additive must be added to an engine at operating temperature. The engine should be started immediately and operated under load for a minimum of 15 minutes to facilitate initial nanofilm deposition.
- Cetane Additive: The cetane improver must be dosed strictly per the provided blend ratio at every treat interval or every 6,000 miles (10,000 km).
- Air Intake Maintenance: The induction system must remain leak-free and clean. Replace the air filter element at standard service intervals to prevent excessive restriction across the vortex mixer.
- Driver Re-assignment Procedure: When reassigning a vehicle to a new driver, cycle power to the telematics module (unplug and re-seat the OBD/J1939 connector) to reset the driver baseline profile. This ensures the AI Coach accurately calibrates to the new operator.
Service Support: All installations include training for fleet maintenance staff and a comprehensive maintenance schedule document. Ongoing technical support is available.
