Fundamental insights on ignition and combustion of natural gas in an active fueled pre-chamber spark-ignition system

Rajasegar, Rajavasanth; Niki, Yoichi; García-Oliver, José M; Li, Zheming; Musculus, Mark P.B. (Elsevier, 2021-10)

[EN] Pre-chamber spark-ignition (PCSI), either fueled or non-fueled, is a leading concept with the potential to enable diesel-like efficiency in medium-duty (MD) and heavy-duty (HD) natural gas (NG) engines. However, the ...
Influence of pilot-fuel mixing on the spatio-temporal progression of two-stage autoignition of diesel-sprays in low-reactivity ambient fuel-air mixture

Rajasegar, Rajavasanth; Niki, Yoichi; Li, Zheming; García-Oliver, José M; Musculus, Mark P. B. (Elsevier, 2021)

[EN] The spatial and temporal locations of autoignition for direct-injection compression-ignition engines depend on fuel chemistry, temperature, pressure, and mixing trajectories in the fuel jets. Dual-fuel systems can ...
Spatio-Temporal Progression of Two-Stage Autoignition for Diesel Sprays in a Low-Reactivity Ambient: n-Heptane Pilot-Ignited Premixed Natural Gas

Rajasegar, Rajavasanth; Niki, Yoichi; García-Oliver, José M; Li, Zheming; Musculus, Mark (SAE International, 2021-04-15)

[EN] The spatial and temporal locations of autoignition depend on fuel chemistry and the temperature, pressure, and mixing trajectories in the fuel jets. Dual-fuel systems can provide insight into fuel-chemistry aspects ...
Verification of diesel spray ignition phenomenon in dual-fuel diesel-piloted premixed natural gas engine

Niki, Yoichi; Rajasegar, Rajavasanth; Li, Zheming; Musculus, Mark P.B.; García-Oliver, José M; Takasaki, Koji (SAGE Publications, 2022-02)

[EN] Dual-fuel (DF) engines, in which premixed natural gas and air in an open-type combustion chamber is ignited by diesel-fuel pilot sprays, have been more popular for marine use than pre-chamber spark ignition (PCSI) ...
