Homogeneous Charge Compression Ignition (HCCI) Combustion Engine- A Review
At present, it is highly required from the automobile sector to develop clean technologies with lower fuel consumption for ambient air quality improvement, green house gas reduction and energy security. Furthermore, due to continuously stringent emission legislation and the fast depletion of the primary energy resources, the development of new highly efficient and environment friendly combustio...
متن کاملAnalysis of combustion in a small homogeneous charge compression assisted ignition engine
Combustion analysis has been conducted on a small two-stroke glow ignition engine, which has similar combustion characteristics to homogeneous charge compression ignition (HCCI) engines. Difficulties such as unknown ignition timing and the polytropic index have been addressed by combining both heat release and mass fraction burn analyses. Results for all operating conditions have shown good cor...
متن کاملAn Experiment Study of Homogeneous Charge Compression Ignition Combustion and Emission in a Gasoline Engine
Homogeneous charge compression ignition technology has exhibited high potential to reduce fuel consumption and NOx emissions over normal spark-ignition engines significantly. Optimized kinetic process technology is implemented to realize homogeneous charge compression ignition combustion in a port fuel injection gasoline engine. The combustion and emission characteristics are investigated with ...
متن کاملControl of Homogeneous Charge Compression (HCCI) Ignition Engine Dynamics
The Homogeneous Charge Compression Ignition (HCCI) combustion concept lacks direct ignition timing control, instead the auto ignition depends on the operating condition. Since auto ignition of a homogeneous mixture is very sensitive to operating conditions, a fast combustion timing control is necessary for reliable operation. Hence, feedback is needed and the crank angle of 50% burnt (CA50) has...
متن کاملEffect of Hydrogen Addition to Natural Gas on Homogeneous Charge Compression Ignition Combustion Engines Performance and Emissions Using a Thermodynamic Simulation
The HCCI combustion process is initiated due to auto-ignition of fuel/air mixture which is dominated by chemical kinetics and therefore fuel composition has a significant effect on engine operation and a detailed reaction mechanism is essential to analysis HCCI combustion. A single zone-model permits to have a detailed chemical kinetics modeling for practical fuels. In this study a single-zone ...
