In this paper, the implication of various grades of hydrogen rich gas on the in-cylinder flame speed, and on the knock propensity, are discussed. The laminar flame propagation speed of methane with various grades of hydrogen-rich gas addition has been calculated. The effect of adding hydrogen, hydrogen rich gas from an ideal reformer (synthesis gas), as well as that from a non-catalytic plasmat...

Opposed rotary piston engines are characterized by high power density, which makes them as an ideal source for hybrid vehicles and range extended electric vehicles. Hydrogen applications can fully exhibit the merits of opposed engines, achieve zero carbon dioxide emissions; however, seriously worsen nitrogen oxides emissions. In this investigation, lean-burn was adopted to low emissions using a...

The article presents the results of laboratory studies a modernized threshing device combine harvester. change in design thresher was carried out order to parameters air flows gap between drum and concave deck. It is shown that introduced changes contribute better separation grain from straw grate separated material prevent reverse movement masses beaters.

Modify the palm fruit thresher machine into a model dry split betel nut peeler by testing tool so that it can find out constraints of machine, and disassembling components or parts to be modified, namely; cover, collection channel, blade drive clutch. The cover is designed function sturdy from impact areca nuts cylindrical. reservoir channel allow peeled enter drain pipe blower in charge blowin...
