摘要:
The invention relates to an improved system of electro-mechanical hydraulic valve lifters for piston engine automobiles that increases fuel economy and reduces fuel emissions. The electro-mechanical hydraulic valve lifters contain that enclose a magnetorheological fluid chamber, containing magnetorheological fluid. A control module manages voltage sent to the magnetorheological fluid in the magnetorheological fluid chamber. The control module introduces various amounts of magnetic flux to the magnetorheological fluid in the magnetorheological fluid chamber. The magnetorheological fluid's viscosity changes based on the amount of magnetic flux applied to it from the electromagnets and, along with the magnetorheological fluid chamber spring, controls how much an intake and exhaust port of the spark plug engine opens to control the amount of fuel used and exhaust let out of the engine.
摘要:
One variation may include a product including: an engine having at least one cylinder, the cylinder having at least one blowdown exhaust valve, at least one scavenging exhaust valve, and at least one intake valve, the engine further having a first actuator connected to the at least one blowdown exhaust valve and a second actuator connected to the scavenging exhaust valve and controller connected to one of the first or second actuator and adapted and configured to advance the timing of one of the blowdown or scavenging exhaust valves when the controller receives a braking signal.

A method to select cylinder and valve operational modes in an internal combustion engine with valves that may be deactivated. A simplified method to select cylinder and valve modes is presented.
摘要:
A valve train for an internal combustion engine that uses motors to open/close intake valves of cylinders. The motors drive the intake valves for each of a plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals. Since the intake valves are driven for each of the plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals, the explosion stroke is performed regularly even when an operation is conducted with only a particular group of cylinders. This makes it possible to inhibit driveability deterioration.
