A phenomenological combustion model for direct-injection, compression–ignition engines

Combustion Modeling for Modern Direct Injection Diesel Engines

In order to comply with stringent pollutant emissions regulations, a detailed analysis of the engine combustion and emission is required. In this field, computational tools like CFD and engine cycle simulation play a fundamental role. Therefore, the goal of the present work is to simulate a high speed DI diesel engine and study the combustion and major diesel engine emissions with more deta...

Combustion Characteristics Detection for Low Pressure Direct Injection Engines Using Ionization Signal

Combustion Control of Diesel Engines Using Injection Timing

We propose a model-based control strategy to adapt the injection settings according to the airpath dynamics of a conventional Diesel engine. This approach complements existing airpath and fuelpath controllers, and aims at accurately controlling the middle of combustion. For that purpose, start of injection is adjusted based on a combustion model and intake manifold conditions. In particular, no...

Multi-Dimensional Modeling of the Effects of Split Injection Scheme on Combustion and Emissions of Direct-Injection Diesel Engines at Full Load State

One of the important problems in reducing pollutant emission from diesel engines is trade-off between soot and NOx. Split injection is one of the most powerful tools that decrease soot and NOx emissions simultaneously. At the present work, the effect of split injection on the combustion process and emissions of a direct-injection diesel engine under full-load conditions is investigated by the c...
