nowadays, due to the increasing power of diesel engines, especially heavy duty diesel engines, and increasing gas pressure inside the combustion chamber, the forces acting on the engine bearings have dramatically raised. on the other hand, becaus eof the competition in the market, it is necessary to increase the engine bearing life and reduce its failure as much as possible. the engine bearings...

Aerospace engineers have always been leading in the field of design using computational simulations. We design vehicles that go fast, fly high, and operate in extreme conditions. Because computation can help reduce expensive tests that physically simulate these extreme conditions, we benefit from computational simulation and design. This is why successful aerospace companies and agencies, such ...

in this study, the mf285 tractor engine vibrations resulting from the use of different combinations of biodiesel, bioethanol and diesel as fuel were studied. engine vibrations in three directions and three engine speeds: 1000, 1600 rpm 2000 and ten fuel level was measured. to investigate the influence of measured parameters on engine vibration of factorial design in a randomized complete block ...

in this paper, the amount of wasted heat from different parts of a 12 liter compression ignition engine and their potential for waste heat recovery were investigated. then, two-stage configuration of organic rankine cycle was introduced for simultaneous heat recovery from exhaust gases and coolant. finally, parameters like hybrid generated power, engine thermal efficiency and brake specific fue...

Abstract The stratosphere is the atmospheric layer with strongest impact on long-range infrasound propagation. Natural and anthropogenic signals are efficiently ducted between refraction altitudes of 30 to 60 km reflections ground thus propagated receivers over long distances. direction favorable stratospheric ducting depends state atmosphere, primarily driven by seasonal variation winds. This ...

in order to comply with stringent pollutant emissions regulations, a detailed analysis of the engine combustion and emission is required. in this field, computational tools like cfd and engine cycle simulation play a fundamental role. therefore, the goal of the present work is to simulate a high speed di diesel engine and study the combustion and major diesel engine emissions with more details,...
