In three-dimensional (3D) computational fluid dynamics (CFD) simulations, the effects of injection timing and spray inclusion angle (SIA) on performance emissions diffusion-controlled Premixed Charge Compression Ignition (PCCI) combustion in part load for a heavy-duty direct (HDDI) diesel engine are studied. The start (SOI) 146° SIA injector is varied between ?70 ?10 °crank (°CA) after top dead...

Estimation of combustion phasing and power production is essential to ensuring proper load control. However, archetypal control-oriented physics-based models can become computationally expensive if highly accurate predictive capabilities are achieved. Artificial neural network (ANN) models, on the other hand, may provide superior computational capabilities. using classical ANNs for model-based ...

The development of modern vehicle drives is aimed at reducing fuel consumption (i.e., crude oil) and minimizing the exhaust emission toxic components. One such implementation a two-stage combustion system. Such system initiates ignition in prechamber, then burning mixture flows into main chamber, where it ignites lean mixture. allows efficient mixtures, both liquid gaseous fuels, cylinder. This...

It has been proposed that ipsilateral motor pathways play a role in the control of ipsilateral movements and recovery of function after injury. However, the extent to which ipsilateral motor pathways are engaged in voluntary activity in intact humans remains largely unknown. Using transcranial magnetic stimulation over the arm representation of the primary motor cortex, we examined ipsilateral ...

In this study, the effect of second injection timing on the combustion and emissions characteristics of a direct injection HCCI gasoline engine was investigated by using ethanol and methanol blended gasoline fuel. For this aim, a diesel engine was converted to an electronically controlled HCCI gasoline engine. The injection timings and fuel quantity for each injection were adjusted to get desir...
