Detailed Technical Analysis of Experimental Data (Table 2.6)
Evaluation of the R3+R7 Device Efficiency vs. Base Engine
This comprehensive analysis evaluates the impact of the R3+R7 device on engine performance, fuel efficiency, and exhaust gas composition across four distinct operating modes. The data confirms that the R3+R7 device acts as a highly effective fuel catalyst and combustion optimizer. It successfully breaks the traditional automotive compromise by simultaneously increasing power and drastically reducing fuel consumption.
1. Fuel Economy & Absolute Efficiency
The R3+R7 device delivers outstanding results in reducing specific fuel consumption (g_e) across all tested engine speeds and throttle positions.
High-Load Optimization (60% Throttle): The device shows its maximum commercial and technical potential under heavy loads.
At 2500 rpm (Mode 2): Specific fuel consumption dropped from 295.8 to 232.5 g/kW·h, achieving a massive 21.4% fuel savings.
At 3500 rpm (Mode 4): Fuel consumption decreased from 277.6 to 224.5 g/kW·h, resulting in a 19.1% fuel savings.
Part-Load Efficiency (40% Throttle): In cruising and moderate acceleration modes, the device maintains highly stable efficiency.
At 2500 rpm (Mode 1): Achieved a 9.6% reduction (down to 243.8 g/kW·h).
At 3500 rpm (Mode 3): Achieved a 9.7% reduction (down to 249.5 g/kW·h).
Key Takeaway: The device perfectly matches the 9% to 30% savings range claimed by OILCOM technology. Saving ~20% of fuel under high load makes this device highly valuable for real-world driving conditions, where fuel consumption is naturally at its peak.
2. Power Output Enhancement
Unlike standard eco-tunings or restrictors that save fuel by "starving" or restricting the engine, the R3+R7 device increases effective engine power (N_e) in every single mode.
Maximum Power Gain: At 3500 rpm and 60% throttle (Mode 4), the engine's power output increased from 44.7 kW to 48.9 kW (+9.4%).
Low-RPM Power Gain: At 2500 rpm and 60% throttle (Mode 2), power increased from 32.2 kW to 33.2 kW (+3.1%).
Part-Load Gains: Power increased by +1.2% in Mode 1 and +1.9% in Mode 3.
Key Takeaway: The concurrent rise in power and drop in fuel consumption proves an increase in the engine's Overall Thermal Efficiency (Indicated Efficiency). The R3+R7 device extracts more mechanical work from each gram of fuel.
3. Exhaust Gas Chemistry & Combustion Quality
The most profound evidence of the R3+R7 device's catalytic nature lies in the exhaust gas data. It fundamentally changes how the fuel-air mixture burns.
A. Radical Destruction of Unburnt Hydrocarbons (CH)
The CH parameter indicates raw, unburnt fuel escaping into the exhaust. The R3+R7 device triggers a massive drop in these emissions:
Mode 4 (3500 rpm, 60%): CH plummeted from 125 ppm down to 52 ppm (a 58.4% reduction).
Mode 3 (3500 rpm, 40%): CH dropped from 117 ppm to 63 ppm (a 46.2% reduction).
Modes 1 & 2 (2500 rpm): CH dropped significantly by 30.5% and 17.3% respectively.
Scientific Explanation: This is a major victory for the R3+R7 device. In a standard engine, when the air-fuel mixture gets richer, CH levels spike because the fuel lacks time or oxygen to burn. The R3+R7 device chemically alters the fuel kinetics, forcing the hydrocarbon chains to ignite faster and burn completely, transforming latent fuel waste into raw engine power.
B. The Air-Fuel Ratio (lambda) and Carbon Dioxide (CO_2) Paradox
Shift to Power Mixture: The base engine operated on a slightly lean mixture (lambda = 1.026 - 1.058). Installing the R3+R7 device shifted the lambda down to a rich/power-oriented zone (lambda = 0.889 - 0.962).
The CO_2 Efficiency Retention: Normally, running an engine at a rich lambda (lambda < 1) causes a severe drop in carbon dioxide (CO_2) because of poor combustion efficiency. However, with the R3+R7 device at 2500 rpm, CO_2 levels remained incredibly high and stable (13.93% and 14.26%, down only minutely from ~14.5%).
At 3500 rpm, CO_2 levels stabilized at 12.90% and 13.42%. Combined with the massive drop in CH, this proves that even on a richer power mixture, the fuel molecules burn with an abnormally high completeness factor.
