Engine Combustion and Emissions Data for Oxyhydrogen/Bio-Isopropanol/Gasoline Ternary Fuel

Experimental data from a study on the composite dilution effect of exhaust gas recirculation and lean-burn strategies in a ternary fuel engine. The dataset includes core operational metrics such as combustion phasing, power outputs, and emissions of NO, CO, and HC. It was authored by Zhanglei Lei and last updated on June 2, 2026.

Use Cases

• Modeling the relationship between EGR rate, lambda (λ), and NOx emissions based on described experimental results.
• Analyzing combustion stability (CoV_IMEP) under different oxyhydrogen flow rates (OFR) and dilution conditions.
• Optimizing engine operating regimes (e.g., OFR, λ, EGR rate) for power output (IMEP, Pmax) and reduced emissions based on the described trade-offs.
• Benchmarking the performance of the BIDI + ONPI + GPI fuel architecture against standard gasoline engines under lean-burn conditions.

Strengths

• Specific experimental parameters are described, including oxyhydrogen flow rates (OFR) of 16 L/min and EGR rates up to 18%.
• Quantifies performance changes, such as a 90.4% average reduction in CO emissions at λ=1.1 versus λ=1, and an 84.86% average reduction in NO emissions with EGR.
• Identifies a specific optimal operational regime: 'OFR = 16 L/min, λ = 1.1, and EGR rate = 12%'.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (207.9 KB), indicating a limited experimental scope.
