摘要： An engine assembly includes an engine structure including an engine block defining a cylinder bore and a cylinder head, a piston located in the cylinder bore, and a camshaft assembly. The piston, cylinder head, and cylinder bore cooperate to define a combustion chamber including first and second longitudinal end surfaces defined by the cylinder head and the piston. A first protrusion may extend longitudinally from one of the first and second longitudinal end surfaces and radially inward from a circumference of the combustion chamber to a location between a first intake port and a first exhaust port in communication with the combustion chamber. The camshaft assembly may include a first intake lobe that opens a first intake valve and a second intake lobe that opens a second intake valve. The first intake lobe may be rotationally offset from the second intake lobe in a rotational direction of the camshaft assembly.

The sampling module receives a first mapping of thermal efficiency of a spark-ignition engine generated based on operation of the spark-ignition engine with a dynamometer. A combustion chamber of the spark-ignition engine has a first compression ratio. The map generating module generates a second mapping of the thermal efficiency of the spark-ignition engine based on the first mapping and the combustion chamber having a second compression ratio. The second compression ratio is different than the first compression ratio.

摘要： A vehicle may include a drive axle, an engine assembly, a coupling device, and an engine load management system. The engine assembly may include a valvetrain including a fixed-lobe camshaft and intake and exhaust valves supported by the engine assembly. The fixed-lobe camshaft may include a first lobe engaged with the intake valve to open the intake valve and a second lobe engaged with the exhaust valve to open the exhaust valve. The first and second lobes may be fixed relative to one another to define a constant valve overlap condition that provides for opening of the intake valve before the exhaust valve is fully closed, creating an engine operating condition that results in combustion instability below an engine load limit. The engine load management system may be in communication with the engine to prevent engine operation below the engine load limit.

摘要： A control system for an engine includes a spark module and a fuel module. The spark module advances spark timing of a cylinder R degrees past a spark limit for N consecutive cylinder firing events, and retards spark timing of the cylinder past the spark limit for M consecutive cylinder firing events after the N consecutive cylinder firing events. The fuel module supplies a rich fuel-air charge to the cylinder for the M consecutive cylinder firing events. According to the system, R is a real number greater than zero, N and M are integers greater than zero, and the spark limit is a control value used to limit an amount of spark advance to prevent spark-knock. A method for controlling an engine is also provided.
