Abstract
Throttle-at-valve apparatus, internal combustion engines employing throttle-at-valve apparatus, and methods of throttling an internal combustion engine using a throttle-at-valve apparatus, where the throttle-at-valve apparatus includes a throttle slide body disposed within a throttle slide cavity that is defined between and in fluid communication with both an unobstructed air intake passage and an intake valve of an internal combustion engine, where the air flow from the air intake passage to the intake valve is regulated by the reciprocal movement of the throttle slide body within the throttle slide cavity.
Claims19
A throttle-at-valve apparatus, comprising:
- a throttle slide body disposed within a throttle slide cavity;
- wherein the throttle slide cavity is defined between and in fluid communication with both an unobstructed air intake passage and an intake valve of an internal combustion engine;
- and
- the throttle slide body is disposed within the throttle slide cavity such that an air flow from the air intake passage to the intake valve is regulated by a reciprocal movement of the throttle slide body within the throttle slide cavity;
- and wherein the throttle-at-valve apparatus is disposed immediately adjacent to the intake valve and thereby substantially eliminates a vacuum chamber between the throttle-at-valve apparatus and the intake valve.
An internal combustion engine, comprising:
- an unobstructed air intake passage;
- an intake valve for a combustion chamber;
- and
- a throttle-at-valve apparatus, the throttle-at-valve apparatus including:
- a throttle slide cavity defined between and in fluid communication with both the unobstructed air intake passage and the intake valve;
- a throttle slide body disposed within the throttle slide cavity, so that a reciprocal movement of the throttle slide body within the throttle slide cavity meters an air flow from the air intake passage to the intake valve;
- and
- wherein the throttle-at-valve apparatus is disposed immediately adjacent to the intake valve and thereby substantially eliminates a vacuum chamber between the throttle-at-valve apparatus and the intake valve.
A method of throttling an internal combustion engine via a throttle controller, comprising:
- disposing a throttle-at-valve apparatus between an unobstructed air intake passage and an intake valve of the internal combustion engine such that the throttle-at-valve apparatus is disposed immediately adjacent to the intake valve and thereby substantially eliminates a vacuum chamber between the throttle-at-valve apparatus and the intake valve;
- wherein the throttle-at-valve apparatus includes a throttle slide cavity between and in fluid communication with both the unobstructed air intake passage and the intake valve, and a throttle slide body disposed within the throttle slide cavity such that a reciprocal movement of the throttle slide body within the throttle slide cavity meters an air flow from the air intake passage to the intake valve;
- retracting the throttle slide body within the throttle slide cavity by the throttle controller via a throttle linkage to increase the air flow;
- and
- extending the throttle slide body within the throttle slide cavity by the throttle controller via the throttle linkage to decrease the air flow.
