Abstract
Implementations herein may include camless engines and methods for operating the same. An engine may comprise a cylinder including a cylinder wall, a piston, a compression ring disposed about the piston, and a cylinder head; a fuel injector in fluid communication with the combustion chamber; an air injector in fluid communication with the combustion chamber; an ignition device in communication with the combustion chamber; an exhaust port in fluid communication with an exhaust manifold and the cylinder; an angular position sensor configured to measure an angular position of a crankshaft in mechanical communication with the piston; and a controller configured to control the fuel injector, the air injector, and the ignition device.
Claims20
An injector, comprising:
- an injector body defined by a first port, a second port, a nozzle, a first internal pathway, a second internal pathway, and a needle cavity;
- and
- a needle defined by a first slot and a second slot and both rotatably disposed and slidably disposed at least partially within the needle cavity;
- wherein the needle is both rotatably disposed and slidably disposed at least partially within the needle cavity such that the needle is configured to rotate between a first open position, wherein the first port and the nozzle are in fluid communication via the first internal pathway and the first slot, and a second open position, wherein the second port and the nozzle are in fluid communication via the second internal pathway and the second slot, and the needle is configured to slide into and out of a closed position, wherein neither the first port nor the second port are in fluid communication with the nozzle.
An injector, comprising:
- an injector body defined by a first port, a second port, a nozzle, a first internal pathway, a second internal pathway, and a needle cavity;
- and
- a needle defined by a first slot and a second slot, the needle slidably and rotatably disposed at least partially within the needle cavity;
- wherein the injector body and the needle are configured such that:
- when the needle is in a first open position, the first slot is aligned with the first port and the first internal pathway such that the first port and the nozzle are in fluid communication via the first internal pathway and the second slot is not aligned with the second port and the second internal pathway, thereby restricting fluid communication between the second port and the nozzle;
- when the needle is in a second open position, the second slot is aligned with the second port and the second internal pathway such that the second port and the nozzle are in fluid communication via the second internal pathway and the first slot is not aligned with the first port and the first internal pathway, thereby restricting fluid communication between the first port and the nozzle;
- and
- when the needle is in a closed position, the needle restricts fluid communication between the nozzle and both the first internal pathway and the second internal pathway.
An injector, comprising:
- an injector body defined by a first port, a second port, a nozzle, a first internal pathway, a second internal pathway, and a needle cavity;
- and
- a needle defined by a first slot and a second slot, the needle movably disposed at least partially within the needle cavity.
