In view of the problem plant entanglement threshing roller in process mechanized flax harvesting, a comb-brush air-suction composite capsule harvesting test stand was designed based on method capsules independently and then breaking to thresh them. The following four parameters were selected as experimental factors: shape comb tooth cross-section, rotational speed roller, relative machine trave...

In this paper, a numerical study is performed to provide the combustion and emission characteristics resulting from fuel-reactivity controlled compression ignition (RCCI) combustion mode in a heavy-duty, single-cylinder diesel engine with gasoline and diesel fuels. In RCCI strategy in-cylinder fuel blending is used to develop fuel reactivity gradients in the combustion chamber that result in a ...

The electrohydraulic servo variable speed volume pump control system (hereinafter referred to as ESPCS) is integrated with a permanent magnet synchronous motor motor), fixed-displacement pump, and hydraulic cylinder. By controlling the speed, output flow of can be controlled, displacement, force, Compared traditional electro-hydraulic valve system, ESPCS has advantages high power-to-weight rati...

Nowadays biodiesel is receiving more attention as a most important renewable energy for using in diesel engines. Inthis research, the application of Response Surface Methodology (RSM) was highlighted to investigate the effects of biodiesel-diesel blends (B0, B20, B50 and B100), engine operating parameters (engine load and  speed) on CO2 emission of a diesel engine. The experiments were conducte...

In internal combustion engines, exhaust valve and its seat gain considerable temperature as the hot gases exit through them. So, the rate of heat transfer should be under control. In this study, the contact heat transfer coefficient has been estimated. An experimental study on an Air-Cooled internal combustion engine cylinder head has been considered. Using the measured temperatures of sensors ...
