Homogeneous Charge Compression Ignition (HCCI) engines stands unique for its efficiency and its less pollutant emitting nature.
Their topics include an asymmetrical solar still with various basin materials, a theoretical investigation of combustion with preformed vortex patterns, the computational analysis of an early direct injected homogeneous charge compression ignition engine with a turbocharger using bio-ethanol and diesel blends, optimizing operating parameters on the wear behavior of manganese phosphate coated die steel, and discussions about the thermodynamic entropy property and its existence in vehicle dynamics of automobiles for improving the mileage.
He refers to what they are working on as an "ultra-efficient internal combustion engine." Their approach is not homogeneous charge compression ignition (FICC1), nor is it reactively controlled compression ignition (RCCI).
However, there are specific applications, where the low- and intermediate-temperature oxidative regions become important, for example, homogeneous charge compression ignition (HCCI) internal combustion engines (ICE) [4-6], lean premixed prevaporized (LPP) combustors in gas turbines [7, 8], and liquid fuel reformers for fuel cell applications [9-11] or industrial safety [12, 13]; in these cases, cool flame reactions largely determine the overall reactivity and have to be taken into account.
Homogeneous charge compression ignition (HCCI) has been attempted with hydrogen, and in the regime where it is feasible, an efficiency gain over spark-ignited hydrogen combustion engines was observed (Stenlaas et al.
The first generation of high-efficiency, low-emission technologies included HCCI (homogeneous charge compression ignition), M-K (modulated kinetics, also called smokeless rich), and UNIBUS (uniform bulky stratified combustion).
Delphi claimed e-Phaser would contribute to the continued development of homogeneous charge compression ignition (HCCI) technology, further reducing fuel consumption and NOx emissions.
