Ignition Delay Period Prediction for Compression Ignition Engines Fueled with Ethanol/Diesel Blends
Journal of EngineeringA key characteristic of diesel engines is predicting the ignition delay period. This work predicts the ignition delay in diesel engines using combinations of ethanol/diesel fuel blend and pure diesel as fuel replacements.

Effects of ambient temperature and injection pressure on biodiesel ignition delay
Journal of Mechanical Engineering and Sciences, 2017 Biodiesels are promoted as alternative fuels due to their potential to reduce dependency on fossil fuels. The main problem in diesel combustion chamber design is to understand the importance of interaction phenomenon between fuel spray and surrounding ...

Ignition Delay in Low Temperature Combustion
SAE Technical Paper Series, 2018 <div class="section abstract"><div class="htmlview paragraph">Low temperature combustion (LTC) strategies present a means of reducing soot and oxides of nitrogen (NOx) emissions while simultaneously increasing efficiency relative to conventional combustion modes. By sufficiently premixing fuel and air before combustion, LTC strategies avoid

A Bayesian approach to the determination of ignition delay [PDF]
Applied Thermal Engineering, 2013 A novel in-cylinder pressure method for determining ignition delay has been proposed and demonstrated. This method proposes a new Bayesian statistical model to resolve the start of combustion, defined as being the point at which the band-pass in-cylinder pressure deviates from background noise and the combustion resonance begins.

Advanced Science, EarlyView.Operando gas diagnostics reveal a previously unrecognized chemical activation (CA) stage during thermal runaway in lithium‐ion batteries. A physics‐informed gas generation kinetics network (GGKNet) is developed to reconstruct reaction pathways and physical models automatically.

Bound Water as a Reinforcing Element for Ultra‐Strong Polyacrylamide
Advanced Science, EarlyView.Rather than acting as a conventional plasticizer, bound water serves as a reinforcing element in polyacrylamide by constructing strong PAM–water–PAM hydrogen‐bond networks. This water‐mediated architecture delivers ultra‐high mechanical strength and exceptional flame resistance, redefining the role of water in polymer reinforcement.
