Embodiment Construction

[0019] The following description refers to the figure 1 Systems and methods for a variable air bag of an engine intake system are depicted. The airbag can be provided on a tubular casing inserted into the engine bulkhead, such as Figure 2-7 shown. Figure 8A-Figure 8C Various embodiments of the disclosure are depicted. In conjunction with the actuators and information from a variety of applicable sensors, the airbags may be adjusted via the controller. The controller can be programmed with instructions to execute control routines (for example, Figure 9 routine) to respond to reduced engine load (e.g., the intake throttle is closed more) by controlling the valves that supply compressed air to the air bags and / or supply ventilation air from the air bags to atmosphere The airbag is inflated. refer to Figure 10 Cooperative operation of first and second airbags positioned at different locations of the air intake is discussed.

Abstract

The invention relates to a method and system for an engine variable charge motion system. Methods and systems are provided for introducing a charge motion to a cylinder via a bladder in an intake manifold runner. In one example, a system may include positioning a bladder in an intake port proximate to a cylinder.

Description

technical field [0001] The present invention generally relates to methods and systems for controlling a vehicle engine to adjust a variable bladder within an intake passage. Background technique [0002] In some cases, increased movement of air and / or fuel charges injected into an engine combustion chamber may improve combustion efficiency. For example, charge motion can increase combustion efficiency by introducing air velocity and turbulence in a direction perpendicular to the direction of flow. By introducing additional kinetic energy into the combustion chamber, the ignition front can move more rapidly and more uniformly across the volume of the combustion chamber to interact with the increased fuel mass before thermal energy is converted to piston motion. In addition, creating turbulence increases the homogenization of the air-fuel mixture within the combustion chamber while increasing the burn rate, which is the time it takes for the air-fuel mixture to completely bur...
