    摘要: Method and arrangement for a turbocompound type internal combustion engine including an exhaust system for ducting the engine's exhaust gases. A supercharger turbine drives a compressor for the engine's combustion air, and an exhaust turbine is placed in the exhaust system downstream of the supercharger turbine for extracting residual energy from the exhaust flow via transmission to the combustion engine's crankshaft. The exhaust system also has an exhaust braking throttle placed downstream of the exhaust turbine. The exhaust braking throttle includes a pressure-controlled exhaust pressure regulator that makes possible variable regulation of an exhaust braking pressure in at least two steps.

    摘要: A variable valve actuation system for providing discrete exhaust and intake valve lift profiles for various operating modes of an internal combustion engine. The variable valve actuation system includes exhaust and intake rocker assemblies, exhaust and intake hydraulic extension devices operatively coupling corresponding rocker assemblies with respective engine valves and exhaust and intake control valves for selectively supplying the pressurized hydraulic fluid to the extension devices so as to independently switch them between a pressurized condition and a depressurized condition. The engine further includes an exhaust brake provided to initiate a small lift of the exhaust valve during the engine braking operation while the exhaust extension device maintains the exhaust valve open during a compression stroke for bleeder-compression release braking. The exhaust and intake valves can be adjusted independently to provide combinations of valve lift modes.

    摘要: A vehicle engine brake has a body in which an internal passageway is defined and a valve member movably positioned within the passageway to selectively restrict flow through the passageway. The valve member is movable between at least first and second positions. In the first position, the valve member blocks a substantial portion of the internal passageway, thereby restricting exhaust gas flow through the engine brake in a flow direction. In the second position, the valve member allows flow through the passageway and past the valve member without substantial restriction.

    摘要: An exhaust system for a multi-cylinder engine can include a plurality of exhaust pipes with first upstream ends connected to exhaust openings of a multi-cylinder engine, and a collecting pipe connected to the second downstream ends of the exhaust pipes for collecting exhaust introduced from the exhaust pipes and directing it to a silencer. The collecting pipe has a front-end portion communicated to exhaust passages of the exhaust pipes, a middle portion for collecting the exhaust introduced from the front-end portion, and a rear-end portion for further collecting the exhaust introduced from the middle portion. The middle portion is provided with exhaust control means for controlling the area of the exhaust passages in accordance with engine speed.

    摘要: Internal combustion engines, which have an exhaust-gas turbocharger that possesses an adjustable turbine geometry, include a waste-gate bypass. When a valve controlling the waste-gate bypass malfunctions, the pressure in the intake-system branch and the exhaust-system branch may increase to an undesirably high level, which may result in component parts being damaged. To prevent this in an internal combustion engine having an exhaust-gas turbocharger, a pressure sensor is provided, which determines the pressure in or upstream from the turbine and transmits it to an electronic control unit. When the control unit determines that a preselected limiting value of the pressure has been exceeded, the turbine geometry is modified so that the turbine may be prevented from being damaged. This arrangement is provided for internal combustion engines, which have an exhaust-gas turbocharger and are equipped with, in particular, an engine-braking device.

    摘要: A vehicle auxiliary braking system is provided to accomplish a braking effect similar to engine braking inexpensively, to extend the life of the brakes, and to reduce the work cycle time in order to improve work efficiency. The system has a centrifugal sensor 20, an accelerator sensor 21, and a braking clutch engaging means that includes a braking hydraulic circuit 22. The centrifugal sensor 20 detects that the vehicle is traveling when the vehicle is moving at or above a prescribed speed. Accelerator sensor 21 detects when the depression amount of the accelerator pedal 6 is at or below a prescribed amount. The braking clutch engaging means engages the clutch that corresponds to the opposite travel direction when the vehicle is traveling at or above the prescribed speed and the accelerator depression amount is at or below the prescribed depression amount.
