Combustion phasing is the main obstacle to the development of controlled auto-ignition based (CAI) engines to achieve low emissions and low fuel consumption operation. Fuel combinations with substantial differences in reactivity, such as diesel/compressed natural gas (CNG), show desirable combustion outputs and demonstrate great possibility in controlling the combustion. This paper discusses a ...

The present work investigates the performance and emission characteristics of hydrous methanol fuelled Homogeneous Charge Compression Ignition (HCCI) engine. In the present work a regular diesel engine has been modified to work as HCCI engine. Hydrous methanol is used with 15% water content in this HCCI engine and its performance and emission behavior is documented. A spark plug is used for ass...

In the present work, pure and Cr-doped MoO3 microrods were successfully prepared through sol gel auto combustion method. The phase evaluation microstructural, dielectric, optical properties of synthesized samples investigated by using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), an impedance analyzer (1 MHz–3 GHz). All showed hexagonal struc...

Nanoparticles of CoGdxFe2 ? xO4 (x = 0%, 25%, 50%) synthesized via sol–gel auto combustion technique and encapsulated within a polymer (Eudragit E100) shell containing curcumin by single emulsion solvent evaporation were formulated in this study. Testing nanoparticles was carried out using different characterization techniques, to investigate composition, crystallinity, size, morphology, surfac...

Abstract In this study, we presented two reliable methods, the sol–gel and autocombustion, to synthesis a high purity BiFeO 3 single phase with low calcination time using glycine as chelating agent. The glycine-autocombustion method produced either or concentrations of reactants (Bi(NO ) + Fe(NO ), while glycine-sol–gel delivered reactants. case tartaric acid urea agents, mixtures Bi 25 FeO 40 ...
