Fuel system

A fuel system, comprising:

• an intake port;
• a first runner in fluid communication with the intake port;
• a second runner in fluid communication with the intake port;
• a cylinder defining a combustion chamber, the first runner allowing the combustion chamber to be placed in fluid communication with the intake port, the second runner allowing the combustion chamber to be placed in fluid communication with the intake port, the first runner positioned downstream from the intake port and upstream from the combustion cylinder, the second runner positioned downstream from the intake port and upstream from the combustion cylinder, whereby fluid in the intake port must choose one of the first and the second runner to travel from the intake port to the combustion chamber;
• and
• a high flow fuel injector in fluid communication with the intake port upstream of the first runner and upstream of the second runner, whereby a high flow of fuel from the high flow fuel injector can reach the combustion chamber through one of:
• the first runner alone, the second runner alone, and a combination of the first runner and the second runner.

A fuel system, comprising:

• a cylinder defining a combustion chamber;
• an intake port upstream of the combustion chamber, the intake port selectively supplying air to the combustion chamber;
• a first runner extending downstream from the intake port to the combustion chamber and a first intake valve that controls fluid communication of the intake port to the combustion chamber through the first runner;
• a second runner extending downstream from the intake port to the combustion chamber and a second intake valve that controls fluid communication of the intake port to the combustion chamber through the second runner;
• and
• a high flow fuel injector in fluid communication with the intake port upstream of a fork defined by the first runner and the second runner, whereby a high flow of fuel from the high flow fuel injector reaches the combustion chamber through the first runner alone while the first intake valve is open and the second intake valve is closed, the second runner alone when the second intake valve is open and the first intake valve is closed, and a combination of the first runner and the second runner when both the first intake valve and the second intake valve are open.
