摘要： A control system for engine braking for a vehicle powered by a turbocharged engine uses a supercharger to assist a turbocharger compressor to boost turbocharger air flow into the engine cylinders. An engine driven air pumping device draws ambient air, or alternately exhaust gas through the pump inlet, compresses the air, and delivers the compressed air through the pump outlet to the turbocharger compressor inlet or alternately the turbocharger compressor outlet. The increased air flow into the cylinders and out of the cylinder exhaust valves increases retarding power of the vehicle.

摘要： In an engine braking system of the type wherein a cam lobe lifts a follower by direct contact, wherein the follower is at least partially contained in a brake housing containing oil. A slave piston is also at least partially contained in the brake housing, and during engine braking, movement of the follower causes the oil to move the slave piston outward. Movement of the slave piston opens an engine braking exhaust valve to open a flow path between an engine cylinder and an exhaust conduit. An oil passage through the follower is provided to lubricate an interface between a flat face of the follower and the cam lobe with oil from the brake housing. The oil passage has an outlet hole that is open on the flat face outside of the contact area between the flat face and the cam lobe.

摘要： When the difference by which pressure in an engine exhaust manifold exceeds pressure in an engine intake manifold becomes less than a selected difference while an intake valve operating mechanism is closing cylinder intake valves at a selected time in the engine cycle, while an EGR system is conveying the engine exhaust component of an air/exhaust mixture from an exhaust system to an intake system, and a certain quantity of NOx is present in engine exhaust entering the exhaust manifold, the quantity of NOx present in engine exhaust entering the exhaust manifold is reduced below that certain quantity by causing the intake valve operating mechanism to close the cylinder intake valves earlier in the engine cycle than the selected time.

摘要： An apparatus and method for varying a counter force to valve spring preload of a brake exhaust valve to undertake engine braking, includes a solenoid controlled hydraulic actuator. A control cylinder is arranged to move with a rocker arm and a control piston is arranged to slide within the control cylinder. During engine braking the control piston slides to press the valve stem to open the brake exhaust valve. An oil chamber is arranged above the control piston and is open into the control cylinder. A source of pressurized oil is selectably introduced into the oil chamber by the solenoid controlled hydraulic actuator to slide the control piston within the control cylinder to open and hold open the brake exhaust valve.

摘要： An engine control system coordinates control of a pressure regulating mechanism associated with a turbocharger turbine and control of a variable valve actuating (VVA) mechanism for expanding the range of possible exhaust gas recirculation rates over a large portion of an engine operating map to provide EGR rates which are greater than typical present-day levels while mitigating engine pumping losses by causing the turbocharger to operate with better efficiency in some regions of the map where it otherwise would not. Turbocharger efficiency is improved by controlling the VVA mechanism to set the timing of operation of its respective cylinder valves in accordance with a predetermined correlation of operating efficiencies of a compressor to timing of operation of respective engine cylinder valves, causing the compressor to operate at points of better efficiency than it otherwise would without use of VVA.
