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...
متن کاملModeling of Heat Losses Within Combustion Chamber of Diesel Engines
The cylinder working fluid mean temperature, rate of heat fluxes to combustion chamber and temperature distribution on combustion chamber surface will be calculated in this research. By simulating thermodynamic cycle of engine, temperature distribution of combustion chamber will be calculated by the Crank-Nicolson method. An implicit finite difference method was used in this code. Special treat...
متن کاملModeling the Effects of Combustion Variability for Application to Idle Speed Control in SI Engines
Combustion in the cylinder of a spark ignition engine, particularly under low load conditions, is subject to cycleby-cycle variations due to factors such as mixture quality and quantity and internal exhaust gas recirculation. The major result of this phenomenon is an increase in the variability of indicated engine torque at a given engine operating point. Automotive control problems dealing wit...

متن کاملExcitation Signals for Nonlinear Dynamic Modeling of Combustion Engines
A crucial point in nonlinear dynamic modeling is the design of a suited excitation signal. It has to fulfill several criteria, like coverage of important amplitude levels and of important frequency range, and for multichannel systems an orthogonal or at least as orthogonal as possible design is desired. Differing from theoretically optimal excitation signals, we suggest the use of smooth signal...
