Numerical Simulations of Pre-Chamber Induced HCCI Combustion (PC-HCCI)

SAE Technical Paper Series, 2023
<div class="section abstract"><div class="htmlview paragraph">Advanced combustion concepts that rely on the lean-burn approach are a proven solution for increasing the efficiency and reducing the harmful emissions of SI engines. The pre-chamber spark ignited (PCSI) engines utilize high ignition energy of the multiple jets penetrating from ...

Modeling for control of HCCI engines

Proceedings of the 2003 American Control Conference, 2003., 2004
The goal of this work is to accurately predict the phasing of homogeneous charge compression ignition (HCCI) combustion for a single cylinder research engine using variable valve actuation (VVA) at Stanford University. Three simple single-zone models were developed and compared with experiment.
