An internal combustion engine may include a first piston reciprocatingly disposed in a first cylinder, and a second piston reciprocatingly disposed in a second cylinder. A crankshaft may be coupled with the first piston and the second piston for rotational motion associated with reciprocating movement of at least one of the first piston and the second piston. A combustion chamber may be fluidly coupled with the first cylinder and the second cylinder. An ignition source may be at least partially disposed within the combustion chamber. An intake valve may provide selective fluid communication between an intake system and the combustion chamber, and an exhaust valve may provide selective fluid communication between an exhaust system and the combustion chamber.

Multiple cylinder engine

An internal combustion engine may include a first piston reciprocatingly disposed in a first cylinder, a combustion chamber fluidly coupled with the first cylinder, and an ignition source at least partially disposed within the combustion chamber. An intake valve may provide selective fluid communication between an intake system and the combustion chamber, an exhaust valve may provide selective fluid communication between an exhaust system and the combustion chamber. A second piston may be reciprocatingly disposed within a second cylinder, configured to draw a fluid into the second cylinder via a fluid inlet, and expel the fluid via a fluid outlet. A pressure accumulator may receive the fluid from the second cylinder and provide a reservoir of pressurized fluid. A crankshaft may be coupled with the first piston and the second piston for rotational motion associated with reciprocating movement of the first piston and the second piston.

A water jet assembly includes a faceplate with at least one opening, a housing constructed to cooperate with the faceplate, and a mover disposed within a chamber of the housing. The mover is configured to move between a first position adjacent the at least one opening of the face plate and a second position offset from the faceplate to provide a variable volume within the chamber. The water jet assembly also includes an exciter connected to the housing and configured to transition the mover between the first position and the second position to increase and decrease the volume to move fluid into and out of the chamber via the at least one opening.
