CAMLESS ENGINES
CAMLESS.ppt (Size: 462 KB / Downloads: 40) INTRODUCTION The cam controls the “breathing channels” of the IC engines , that is, the valves through which the fuel air mixture (in SI engines) or air(in CI engines) is supplied and exhaust driven out. Besieged by demands for better fuel economy, more power, and less pollution, motor engineers around the world are pursuing a radical “camless” design by which it can give us more fuel efficiency. CAMS Control the breathing channels (valves) of an IC engine Connected to camshaft which is operated by crankshaft Cams push open valves at proper time & guide their closure But they are inflexible except VTEC & VVT-I Engineers could not vary timing, lift & duration of valve opening infinitely CAMLESS ENGINES Eliminated mechanical linkages Could provide infinite variation of valve parameters It can make engines clean, efficient & responsive Actuators It is a electro-hydraulic camless valve train (ECV) Uses elastic property of compressed hydraulic fluid which acts like a liquid spring, accelerates & decelerates the valves Conclusion Even though some disadvantages are present, we can expect electrohydraulic & electromechanical valves to replace the conventional camshaft technology.
