    摘要: A collector is disclosed for the primary pipes of an exhaust manifold in an internal combustion engine. The collector includes a common cavity and a plurality of primary pipes having a first cross-sectional area at their outlet ends and second cross-sectional area at an upstream location, the first cross-sectional area being less than the second cross-sectional area, with the primary pipes being in direct contact with the common cavity of the collector and further arranged to include a single central pipe with the remainder of the pipes spaced around the central pipe, with the outlet of the central pipe being formed as a conically tapering portion and the outer wall of the central pipe forming part of the inner wall of the remainder of the pipe.

    摘要: A method is provided for reducing turbolag in a turbocharged internal combustion engine including an inlet manifold, an exhaust manifold, an exhaust gas recirculation (EGR) valve and a Variable Geometry Turbine (VGT) turbo unit. The method includes demanding torque for shifting the internal combustion engine from a stationary engine mode to a transient engine mode, closing the EGR valve during the transient engine mode, repositioning guide vanes of the VGT turbo unit from a first position when in the stationary engine mode to a second position when in the transient engine mode, increasing a duration of overlapping of at least one inlet valve and at least one outlet valve provided in a cylinder head of the internal combustion engine from a first duration when in the stationary mode to a second duration when in the transient mode for increasing the amount of air flowing from the inlet manifold to the exhaust manifold and thereby increasing acceleration of a turbine of the VGT turbo unit.

    摘要: An internal combustion engine arrangement (10) for a vehicle with a turbo charger (16) and configured for influencing the boost pressure of the turbo charger at low engine speeds. The arrangement includes a tank (32) for storing a pressure medium, a line (31) for supplying pressure medium to the turbo charger and a valve (30) for controlling the supply of pressure medium. The line (31) connects to a mouthpiece (33) directed toward the impeller of the turbo charger (16). A pipe line (23) is connected to the exhaust-gas line (16) and the inlet line (20) enabling the recirculation of exhaust gas from the exhaust-gas line to the inlet line.

    摘要: A turbo-charged internal combustion engine with a twin-entry exhaust turbine and with a valve arrangement (20) disposed in the turbine housing (11). By means of the valve arrangement (20) the exhaust channels (9, 10) in the turbine housing can be short-circuited. The valve arrangement also functions as a waste-gate valve by virtue of the fact that its valve element (26), in one position, permits exhaust to by-pass the turbine housing through a shunt (18).
