摘要： An intake port pressure control system comprises an intake passage leading to a cylinder in an engine, and a check valve in the intake passage to allow fluid flow toward the cylinder and obstruct fluid back-flow in the reverse direction. A bypass port is located on the intake passage so that the bypass port communicates with a trapped volume defined by the portion of the intake passage between the check valve and intake valve. The intake port pressure control system further comprises a control valve having an outlet passage, a secondary passage, and an actuator enabling communication between the outlet passage and secondary passage. The actuator further enables active adjustment of the flow area of the flowpath between the secondary passage and outlet passage throughout a range of engine operating conditions. The outlet passage is connected to the bypass port, and the secondary passage is connected to a secondary air source. The control valve enables a controlled air flow therein between the secondary air source and the trapped volume when the intake valve is closed.

摘要： An intake reservoir system is for an engine having an intake passage leading to a cylinder, and a check valve in the intake passage to allow fluid flow toward the cylinder and obstruct fluid back-flow in the reverse direction. A bypass port is located on the intake passage so that the bypass port communicates with a trapped volume defined by the portion of the intake passage between the check valve and cylinder. The intake reservoir system comprises an inflower for enabling fluid to flow into the trapped volume when the pressure therein is at least equal to the pressure upstream of the check valve. The intake reservoir system further comprises a reservoir cavity, a port passage connected between the reservoir cavity and bypass port enabling communication between the reservoir cavity and trapped volume, and a volume controller enabling adjustment of the volume of the reservoir cavity.

摘要： An automotive vehicle engine includes multiple power-producing cylinders including a first group of deactivation cylinders capable of being selectively deactivated during engine operation and a second group of cylinders capable of continued power production during deactivation of the first group. An air intake system includes a turbocharger compressor connected to intake valves of all the cylinders for supplying charge air to the cylinders. An exhaust system includes a turbine connected for driving the compressor, which includes twin scrolls with first and second exhaust flow passages separately connecting the turbine with exhaust valves of the first group of cylinders and with exhaust valves of the second group of cylinders. At high loads, the engine operates on all cylinders and is turbocharged for maximum power. At lower loads, the first group of cylinders may be deactivated and the engine may be driven by the second group of cylinders to obtain increased fuel efficiency.

摘要： An engine charge control system operates by initially reducing power from full load by retarding exhaust valve closing timing to increase exhaust gas charge dilution up to the limit for efficient operation. Further load reductions are made by reducing charge mass without increased dilution via alternative steps such as throttling (in conjunction with intake check valves or using individual cylinder valves) or retarding intake valve opening timing without throttling. Partial substitution of external charge dilution is also contemplated.

摘要： An active reed valve for a fluid passage comprising a sealing means sealingly fixed to the passage walls, and a primary petal seat having a primary seat port and a downstream primary seat end. A flexible primary petal is sealingly attached to the primary petal seat in a cantilevered manner. The primary petal seat and a primary baffle are sealingly attached to the sealing means. The primary baffle is spaced apart from the primary petal seat so that fluid can flow between the primary baffle and petal seat. A positioning means enables the primary baffle to sealingly engage the primary seat wherein fluid flow between the primary baffle and petal seat is directed by the primary baffle toward the primary seat port. Fluid flow through the primary seat port is allowed by the primary petal flexing away from the primary petal seat and fluid back-flow is obstructed by seating of the primary petal on the primary petal seat. The positioning means further enables adjustable separation between the downstream primary baffle end and downstream primary seat end.
