Journal ArticleDOI
Impact of emulsion fuel with nano-organic additives on the performance of diesel engine
Wenming Yang,Hui An,Siaw Kiang Chou,Kian Jon Chua,Balaji Mohan,Vedharaj Sivasankaralingam,Vallinayagam Raman,Amin Maghbouli,Jing Li +8 more
TL;DR: In this article, the performance and emissions of the diesel engine fueled by the emulsion fuel are tested and compared with that of pure diesel, and the results indicate that a better brake thermal efficiency can be achieved with the EM fuel.
Journal ArticleDOI
Optimization of biodiesel fueled engine to meet emission standards through varying nozzle opening pressure and static injection timing
TL;DR: In this paper, the performance and emissions of B20 blend of MME was investigated using a single cylinder diesel engine at various nozzle opening pressures (NOP) and static injection timings (19°, 21°, 23°, 25°, 27° bTDC) in accordance with ISO 8178 D2 cycle.
Journal ArticleDOI
Homogeneous charge compression ignition (HCCI) and partially premixed combustion (PPC) in compression ignition engine with low octane gasoline
Yanzhao An,Mohammed Jaasim,Vallinayagam Raman,Francisco E. Hernández Pérez,Jaeheon Sim,Junseok Chang,Hong G. Im,Bengt Johansson +7 more
TL;DR: In this paper, the in-cylinder combustion for low octane 70 primary reference fuel (PRF70) was investigated by the method of the flame index during the transition from homogeneous charge compression ignition (HCCI) combustion to partially premixed combustion (PPC).
Journal ArticleDOI
Combustion stability study of partially premixed combustion with low-octane fuel at low engine load conditions
Yanzhao An,Vallinayagam Raman,Qinglong Tang,Hao Shi,Jaeheon Sim,Junseok Chang,Gaetano Magnotti,Bengt Johansson +7 more
TL;DR: In this paper, the sensitivity of combustion stability to the intake air temperature for partially premixed combustion (PPC) was investigated in a full view optical engine at low load condition.
Journal ArticleDOI
Impact of spray-wall interaction on the in-cylinder spatial unburned hydrocarbon distribution of a gasoline partially premixed combustion engine
Vallinayagam Raman,Qinglong Tang,Yanzhao An,Hao Shi,Priybrat Sharma,Gaetano Magnotti,Junseok Chang,Bengt Johansson +7 more
TL;DR: In this paper, the authors investigated the detailed spray-wall interaction and its effects on the two-stage ignition, i.e., low and high-temperature heat release (LTHR and HTHR), and the in-cylinder spatial UHC distribution of PPC in a full-view optical engine at low engine load.
