Abstract
An engine assembly may include an engine block, a first piston, a second piston, and a cylinder head. The cylinder head and the engine block may define a first combustion chamber and a second combustion chamber. The cylinder head may define a first intake port and a second intake port. The first intake port may be in communication with the first combustion chamber and may include a first inlet extending through an upper surface of the cylinder head. The second intake port may be in communication with the second combustion chamber and may include a second inlet extending through a side of the cylinder head.
Claims20
A cylinder head comprising:
- a first intake port defined in the cylinder head that provides air flow to a first combustion chamber and includes a first inlet extending through an upper surface of the cylinder head;
- and
- a second intake port defined in the cylinder head that provides air flow to a second combustion chamber and includes a second inlet extending through a side of the cylinder head.
An engine assembly comprising:
- an engine block defining a first cylinder bore and a second cylinder bore;
- a first piston located in the first cylinder bore;
- a second piston located in the second cylinder bore;
- and
- a cylinder head coupled to the engine block, cooperating with the first cylinder bore and the first piston to define a first combustion chamber and cooperating with the second cylinder bore and the second piston to define a second combustion chamber, the cylinder head defining:
- a first intake port in communication with the first combustion chamber and including a first inlet extending through an upper surface of the cylinder head;
- and
- a second intake port in communication with the second combustion chamber and including a second inlet extending through a side of the cylinder head.
An engine assembly comprising:
- an engine block defining a first cylinder bore and a second cylinder bore;
- a first piston located in the first cylinder bore;
- a second piston located in the second cylinder bore;
- and
- a cylinder head coupled to the engine block, cooperating with the first cylinder bore and the first piston to define a two-stroke operating cycle combustion chamber and cooperating with the second cylinder bore and the second piston to define a four-stroke operating cycle combustion chamber, the cylinder head defining:
- a first intake port in communication with the two-stroke operating cycle combustion chamber and including a first inlet extending through an upper surface of the cylinder head;
- a second intake port in communication with the four-stroke operating cycle combustion chamber and including a second inlet extending through a side of the cylinder head;
- and
- a first exhaust port in communication with the first combustion chamber and the second combustion chamber and providing exhaust gas from the first combustion chamber to the second combustion chamber.
