This paper studies the effect of nitric oxide (NO) on the onset of knock in a cooperative fuel research (CFR) engine. The experiments are conducted at both the standard knock intensity (SKI) condition for research octane number (RON) tests, as well as at a richer operating condition of a similar knock intensity but a higher compression ratio. Iso-octane is the fuel. The experiments show clearly...

The capability of a cell bound biosurfactant produced by Lactobacillus pentosus, to accelerate the bioremediation of a hydrocarbon-contaminated soil, was compared with a synthetic anionic surfactant (sodium dodecyl sulphate SDS-). The biosurfactant produced by the bacteria was analyzed by Fourier transform infrared spectroscopy (FTIR) that clearly indicates the presence of OH and NH groups, C=O...

homogenous charge compression ignition (hcci) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. to avoid excessive pressure rise rate and knocking, hcci engines are fueled with highly diluted mixture using a combination of excess air and/or egr. hcci combustion is attractive due to ext...

Nowadays, automobiles and motorcycles manufacturer produced more powerful efficient engines. This engine usually has high compression pressure to achieve performance economic gasoline consumption. Unfortunately, only few people known that requires octane number gasoline. The aim of this research were find out the differences power & torsion output one cylinder combustion which given several...

We started to implement SMP support for the OpenBSD/sgi port and selected the SGI Octane as the first target machine. We are now at the point where we have almost finished, except for the implementation of some non-critical features. SMP support is now operational on SGI Octane systems and the code has been merged into the OpenBSD tree.

Poly-generation systems are an exciting new technology that provide alternative to separating existing energy production methods in buildings. A poly-generation system enables the efficient simultaneous of heating, cooling, fresh water, and electricity, resulting many technological, economic, recovery, environmental advantages. This study numerically investigates three proposed novel solar-driv...

The normal specifications of motor gasolines as well as their combustion characteristics in internal combustion engines are reviewed in this paper. The effective factors influencing the fuel performance, such as the molecular structure of the fuel constituents, the operating conditions and the atmospheric pressure and temperature are also discussed. A relationship between the optimum octane num...
