Hydrogen is one of the most promising alternative fuels for transportation industry. The use hydrogen to enable lean burn in internal combustion engines an attractive solution reducing CO2 emissions from two points views: substitution carbon-based and increased thermal efficiency due operation. Combining this strategy with passive pre-chamber ignition system gasoline/hydrogen blends even more i...

Due to the difficulty directly study ammonia, present work investigated engine performance of lean iso-octane/air mixture approximate ammonia combustion behaviour. The was conducted using a single cylinder modified diesel that features spark plug and glow in sub-chamber. investigations varied speeds (1000 1500 RPM), voltages (6 10 volts), excess air ratios (1.4 1.8), ignition timings (-2 -5 °BT...

Premixed flames encounter gradients of mixture equivalence ratio in stratified charge engines, lean premixed gas-turbine engines, and a variety of other applications. In cases for which the scales—spatial or temporal—of fuel concentration gradients in the reactants are comparable to flame scales, changes in burning rate, flammability limits, and flame structure have been observed. This paper us...

Lean production has become an integral part of the manufacturing landscape as its link with superior performance and its ability to provide competitive advantage is well accepted among academics and practitioners. Lean production helps producers in overcoming the challenges organizations face through using powerful tools and enablers. However, most companies are faced with restricted resources ...

Liquefied natural gas (LNG) use as marine fuel is increasing. Switching diesel to LNG in ships significantly reduces air pollutants but the methane slip from engines can worst case outweigh CO2 decrease with an unintended effect on climate. In this study, a oxidation catalyst (MOC) investigated engine experiments lean-burn conditions. Since highly efficient needed oxidize very sensitive sulfur ...

Introduction: Severe burns result in prolonged hypermetabolism and skeletal muscle catabolism. Rehabilitative exercise training (RET) programs improved muscle mass and strength in severely burned children. The combination of RET with A-blockade or testosterone analogs showed improved exercise-induced benefits on body composition and muscle function. However, the effect of RET combined with mult...
