Cylinder Charge Temperature Control for an Internal Combustion Engine
First Claim
1. A method of operating an engine including at least a first cylinder and a second cylinder, the method comprising:
- operating the first cylinder of the engine to provide a net flow of gases from an intake manifold to an exhaust manifold over a plurality of cycles of the first cylinder and performing auto-ignition in said first cylinder of a mixture including said gases; and
during said operation of the first cylinder, operating the second cylinder of the engine to provide a net flow of gases from the exhaust manifold to the intake manifold.

Abstract
As one embodiment, a method of operating an engine including at least a first cylinder and a second cylinder is provided. The method comprises operating the first cylinder of the engine to provide a net flow of gases from an intake manifold to an exhaust manifold over a plurality of cycles of the first cylinder and performing auto-ignition in said first cylinder of a mixture including said gases; and during said operation of the first cylinder, operating the second cylinder of the engine to provide a net flow of gases from the exhaust manifold to the intake manifold.

17. A method, comprising:
-
during a first operating condition, operating a first cylinder and a second cylinder to each provide a net flow of gases from an intake manifold to and an exhaust manifold while each combusting a mixture including said gases and fuel; during a second operating condition, operating the first cylinder to provide a net flow of gases from the intake manifold to the exhaust manifold while combusting a mixture including said gases and fuel by auto-ignition, and operating the second cylinder of the engine to provide a net flow of gases from the exhaust manifold to the intake manifold. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. An engine system for a vehicle, comprising:
-
a first cylinder including a piston moveably arranged within the first cylinder configured to initiate combustion within the first cylinder by auto-ignition; a second cylinder; an intake manifold communicating with the first and second cylinders; an exhaust manifold communicating with the first and second cylinders; a control system configured to operate the first cylinder to repetitively perform auto-ignition and further configured to vary a flow rate of gases supplied to the intake manifold from the exhaust manifold via the second cylinder to adjust a timing of said auto-ignition performed by the first cylinder. - View Dependent Claims (25, 26)
