Abstract
Methods and systems for supplying fuel to a diesel engine during a cycle of a cylinder are described. In one example, a cylinder is supplied fuel via two fuel injectors having different fuel flow rates. The two fuel injectors may be arranged opposed to each other or in a way that fuel spray from one injector intersects and collides with fuel spray from the other injector.
Claims14
An engine system, comprising:
- an engine including at least one cylinder and two pistons positioned within the at least one cylinder;
- a first diesel fuel injector supplying fuel to the at least one cylinder;
- a second diesel fuel injector supplying fuel to the at least one cylinder, the second diesel fuel injector a higher fuel flow rate injector than the first diesel fuel injector;
- and
- a cavity in a first of the two pistons, where the cavity is asymmetric about a horizontal centerline of the cavity, and where a first opening width of the cavity is less than a second opening width of the cavity.
