Hybrid control of homogeneous charge compression ignition (HCCI) engine dynamics
TL;DR: In this article, a six-cylinder heavy-duty HCCI engine was controlled on a cycle-to-cycle basis in real-time by using model predictive control (MPC).

TL;DR: The HYPO-RT-PC trial as mentioned in this paper compared conventional fractionation and ultra-hypofractionation up to 6 years after treatment in patients with localised prostate cancer, and the results showed that UHF was non-inferior to traditional fractionation regarding 5-year failure-free survival and toxicity.
Proceedings ArticleDOI
The Effect of Combustion Chamber Geometry on HCCI Operation
TL;DR: In this article, the effect of the combustion chamber geometry and the turbulence on homogeneous charge compression Ignition (HCCI) operation has been experimentally investigated, and it was shown that the high turbulent square bowl in piston combustion chamber was compared with a low turbulent disc combustion chamber.
Proceedings ArticleDOI
Model predictive Control of Homogeneous Charge Compression Ignition (HCCI) engine dynamics
TL;DR: In this paper, a six-cylinder heavy-duty HCCI engine was controlled on a cycle-to-cycle basis in real time using a variety of sensors, actuators and control structures for control of the combustion in comparison.
Proceedings ArticleDOI
Optical Diagnostics Applied to a Naturally Aspirated Homogeneous Charge Compression Ignition Engine
TL;DR: In this paper, basic optical properties of a homogeneous charge compression ignition (HCCI) engine have been investigated in order to characterize the combustion process, and the results obtained are believed to be valuable in future applications of optical diagnostics in similar environments.
