AN EXPERIMENTAL AND MODELING STUDY TO INVESTIGATE EFFECTS OF TWO-STAGE DIRECT INJECTION VARIATIONS ON HCCI COMBUSTION

Ali Turkcan; Ahmet Necati Ozsezen; Mustafa Canakci; Coşkun, Gökhan; Soyhan, Hakan Serhad; Usame Demir (TAYLOR & FRANCIS INC, 2015)

In this study, homogenous charge compression ignition (HCCI) combustion with two-stage direct injection (TSDI) strategies was modeled with stochastic reactor model (SRM) and validated by using the experimental results of ...
Analysis of an HCCI engine combustion using toluene reference fuel for different equivalence ratios - Comparison of experimental results with CFD and SRM simulations

Coşkun, Gökhan; Yusuf Delil; Usame Demir (ELSEVIER SCI LTD, 2019)

In this study; performance of 0-D and Computational Fluid Dynamics (CFD) software with two different chemical mechanisms are investigated in an HCCI engine using toluene reference fuel (79% toluene and 21% n-heptane). For ...
Computational investigation of combustion and emission characteristics of toluene reference fuel (TRF) mixtures in an HCCI engine using stochastic reactor model

Coşkun, Gökhan; Usame Demir; Yılmaz, Neslihan; Soyhan, Hakan Serhad (SPRINGER HEIDELBERG, 2017)

In this study, a homogeneous charge compression ignition (HCCI) engine was fueled with primary reference fuel (PRF) and toluene mixture using a zero-dimensional simulation code called stochastic reactor model (SRM) for ...
