Oxy-fuel combustion for carbon capture and storage in internal combustion engines - A review

Xiang Li et al.

Summary: As global warming worsens, oxy-fuel combustion is seen as a promising solution to reduce carbon emissions in IC engines. Optimizing oxygen concentration, EGR rate, ignition timing, compression ratio, fuel injection, and water injection is crucial for achieving this goal.

Experimental investigation on ammonia combustion behavior in a spark-ignition engine by means of laminar and turbulent expanding flames

Charles Lhuillier et al.

Summary: The study aims to elucidate the combustion characteristics of ammonia blends under engine-relevant turbulent conditions, finding that the effects of hydrogen or methane enrichment observed in SI engines cannot be fully explained by the measured laminar burning velocities. The combustion regimes studied are at the boundary between thin and broken reaction zones, influenced by flame-turbulence interactions.

The effect of oxygen content on the turbulent flame speed of ammonia/oxygen/nitrogen expanding flames under elevated pressures

Shixing Wang et al.

Summary: Ammonia is a promising carbon-free fuel and hydrogen carrier for renewable energy, with turbulent flame speed found to increase with oxygen content but turbulent-to-laminar flame speed ratio decreasing. The study presents correlations of turbulent flame speed based on Karlovitz number and Damkohler number, showing that ammonia/oxygen/nitrogen mixtures can achieve similar turbulent flame speed as methane/air.

Spark effects on compression ignition of PRF95 direct injection spray in a constant volume combustion chamber

Libing Wang et al.

Summary: The study found that peak heat release rate initially increases then decreases with ambient temperature, with the highest rate occurring around 650-700 K. The timing of peak heat release rate decreases with increased ambient temperature or oxygen levels. Under low ambient temperature, oxygen levels play a major role in affecting combustion. Proper spark timing can advance peak HRR and shorten ignition delay, especially at low ambient temperatures.

Effect of CH4, Pressure, and Initial Temperature on the Laminar Flame Speed of an NH3-Air Mixture

Xiaolei Zhang et al.

Summary: This study focuses on the laminar flame speed of NH3-CH4-air mixture, revealing the effects of CH4 in the fuel and the impact of high pressure and temperature on flame speed. The research results show good agreement with experimental data and propose a more effective method to calculate the flame speed of NH3-air mixture.

Operating Limits for Ammonia Fuel Spark-Ignition Engine

Christine Mounaim-Rousselle et al.

Summary: This paper explores the potential use of ammonia as a carbon-free fuel in a spark-ignition engine, finding that adding less than 10% H-2 to NH3 can allow the engine to operate stably in most conditions. Introducing a 10% dilution limit of H-2 into the intake gases can reduce NOx emissions by up to 40% while maintaining stable operation.
