TL;DR: In this paper, a premixed charge compression ignition engine, and a control system, is provided which effectively initiates combustion by compression ignition and maintains stable combustion while achieving extremely low nitrous oxide emissions, good overall efficiency and acceptable combustion noise and cylinder pressures.

TL;DR: In this article, a structure for the diesel combustion process based on a combination of previously published and new results is proposed, which is validated with data from production-like direct injection diesel engines.

TL;DR: In this paper, the influence of oxygenated hydrocarbons as additives to diesel fuels on ignition, NOx emissions and soot production has been examined using a detailed chemical kinetic reaction mechanism.

TL;DR: In this article, a combined experimental and modeling study of product gas temperatures in engine combustion and their influence on emission levels is presented, which is the principal cause for the large temperature dependence of the extended Zeldovich NO{sub x} mechanism.

TL;DR: In this paper, an operating condition detection unit for detecting engine operating a condition which indicates combustion history, determining a combustion history value based on an engine operating condition signal, and feeding at least one control signal based on the value.
