Autoignition studies of NH3/CH4 mixtures at high pressure
, 2020 Autoignition delay times of NH3/CH4 mixtures with CH4 fractions of 0%, 5%, 10% and 50% were measured in a rapid compression machine at equivalence ratio φ = 0.5, pressures from 20 to 70 bar and temperatures from 930 to 1140 K.

Visualization of the homogeneous charge compression ignition/controlled autoignition combustion process using two-dimensional planar laser-induced fluorescence imaging of formaldehyde [PDF]
, 2003 The paper reports an investigation into the HCCI/CAI combustion process using the two-dimensional PLIF technique. The PLIF of formaldehyde formed during the low-temperature reactions of HCCI/CAI combustion was exciting by a tunable dye laser at 355nm ...

Neki aspekti primene različitih metoda u ispitivanju eksplozivnih materija / Some aspects of applying different methods in testing explosives [PDF]
Vojnotehnički Glasnik, 2004 Eksplozivne materije, pored relativno velike osetljivosti na dejstvo spoljnih impulsa, imaju sklonost ka termičkoj dekompoziciji usled čega postoji opasnost od njihovog samozapaljenja u slučaju ispunjenja kritičnih uslova. Radi toga uspostavljen je čitav

Hydrogen SI and HCCI Combustion in a Direct-Injection Optical Engine [PDF]
, 2009 Hydrogen has been largely proposed as a possible alternative fuel for internal combustion engines. Its wide flammability range allows higher engine efficiency with leaner operation than conventional fuels, for both reduced toxic emissions and no CO2 ...
