BACKGROUND The purpose of this study was to compare the efficacy of the hybrid chemotherapeutic regimen COPP/ABV/IMEP (cyclophosphamide-vincristine-procarbazine-prednisone-doxorubicin-bleomycin-vinblastine-ifosfamide-methotrexate-etoposide) (CAI) with that of the standard regimen COPP/ABVD (COPP/ABV, dacarbacine) (CA) in the treatment of advanced-stage Hodgkin's disease (HD). PATIENTS AND MET...
Biodiesel as a clean energy source could reduce environmental pollution compared to fossil fuel, so it is becoming increasingly important. In this study, we investigated the effects of different pilot injection timings from before top dead center (BTDC) and exhaust gas recirculation (EGR) on combustion, engine performance, and exhaust emission characteristics in a common rail diesel engine fuel...
Experimental studies were conducted on an off-highway heavy duty diesel engine running on different viscosity grade engine oil, for determining the friction power in a firing engine by measuring the indicated mean effective pressure (IMEP) by in–cylinder pressure sensor and calculating the Indicated power and Brake power. It is known fact that hydrodynamic friction is related to the viscosity o...
The potential use of hydrogen peroxide as an ignition promoter to enable the ammonia in compression engines is explored current study. A simplified numerical HCCI engine model within Chemkin Pro suite employed. investigation reveals that proposed significantly more advantageous against conventional method preheating intake charge achieve ignition, whilst using a glow plug. In particular, IMEP, ...
ABE can be used as an alternative fuel for engines. This paper studies the combustion and emission performances of SI engine with GPI plus ABEDI at different speeds loads. The operating conditions included 1000–2600 rpm MAP = 50 kPa loads 30–70 a speed 1800 rpm. ABEDIr contained 0%, 20%, 40%, 60%, 80%, 100%. At 1000–1800 or 2200–2600 rpm, testing results showed corresponding to maximum IMEP 80%...
To improve the non-uniformity of a multi-cylinder marine diesel engine caused by manufacturing assembly errors and performance degradation fuel injection system, with instantaneous speed applied as control target, feedback variable each cylinder’s exhaust temperature was used to obtain information quantity cylinder variable; inhomogeneity accomplished modifying pulse spectrum. The model AVL Cru...
Abstract The development of new piston geometries has shown great potential to achieve the low levels soot emissions required by regulation. Thus, present paper aims characterize influence a design over combustion process. It is characterized introduction protrusions around periphery bowl, evenly spaced. performance this geometry compared other that have been extensively analyzed in literature,...
This study investigated the effects of high exhaust gas recirculation (EGR) rates on dimethyl ether (DME) fuel combustion performance, exhaust emissions and particle emission characteristics in a small direct injection diesel engine under various injection timings. To examine the effect of EGR and injection timings, the experiment was performed under high EGR rates (0%, 30%, 50%) and injection ...
Lignocellulosic materials have been identified as potential carbon–neutral sources of sustainable power production. Catalytic conversion of lignocellulosic biomass results in liquid fuels with a variety of aromatic molecules. This paper investigates the combustion characteristics and exhaust emissions of a series of alkylbenzenes, of varying number of methyl branches on the monocyclic aromatic ...
