| 20140245983 | AIR INTAKE SYSTEM FOR INTERNAL COMBUSTION ENGINE - An intake manifold is provided that controls swirl on entry to a combustion chamber. Each intake manifold includes a fin or rib portion positioned to reduce or eliminate swirl induced by the configuration of the intake manifold, particularly when used in a large engine having a left bank and a right bank of combustion chambers. By controlling swirl induced by the intake manifold, swirl consistency is improved between engine cylinders and between the left bank and the right bank, improving the consistency of power output and reducing emissions, particularly particulate emissions, also called smoke. | 09-04-2014 |

| 20100065003 | INDUCTION SYSTEM FOR INTERNAL COMBUSTION ENGINE - An induction system for an internal combustion engine includes an upper intake for receiving air from a supply, such as a turbocharger, and a lower intake which combines a cylinder valve actuator cover, a plenum for receiving air from the upper intake, and a number of intake runners which extend across, an integrally with, the cylinder valve actuator cover to cylinder head intake ports which are configured at outboard sides of the engine cylinder head. | 03-18-2010 |
| 20110174257 | Intake Manifold - An intake assembly for a 3-cylinder, V-configured engine comprises an intake manifold configured to conduct combustion air to a first, two-cylinder, cylinder head housing assembly and a second, single-cylinder, cylinder head housing assembly. A centrally extending plenum defines a plenum axis. A first plurality of intake runners, in fluid communication with the plenum, extend from a front side and transition through a circumferential arc around an upper side to deliver combustion air to, the first, two-cylinder, cylinder head housing assembly. A single intake runner, in fluid communication with the centrally extending plenum, extends from a rear side and transitions through a circumferential arc around the upper side to deliver combustion air to, the second, single-cylinder, cylinder head housing assembly. A zip tube delivers combustion air to the central plenum at a location that is between one of the first plurality of intake runners and the single cylinder intake runner. | 07-21-2011 |
| 20110277717 | INTAKE MANIFOLD - An intake manifold assembly for mounting to a cylinder head and configured to deliver combustion air thereto comprises a centrally positioned zip tube having an opening for receipt of combustion air from a throttle body. First and second flow runners extend from the centrally positioned zip tube to terminate at a common intake manifold plenum for delivery of combustion air thereto. A centrally located access opening is defined between the first and second flow runners. | 11-17-2011 |
| 20160108867 | AIRBOX FOR ENGINE - An airbox for an engine is provided. The airbox includes a first cylinder bank including a plurality of first cylinder sections. The airbox also includes a second cylinder bank including a plurality of second cylinder sections. The airbox further includes an isolation assembly provided in association with the first cylinder bank and the second cylinder bank. The isolation assembly is configured to isolate at least one first cylinder section of the plurality of first cylinder sections from another first cylinder section of the plurality of first cylinder sections, at least one second cylinder section of the plurality of second cylinder sections from another second cylinder section of the plurality of second cylinder sections, and the first cylinder bank from the second cylinder bank. | 04-21-2016 |
| 123184350 | Plural plenums | 3 |
| 20090301422 | Device for supplying air to a multiple-cylinder engine head - A device including two air distribution chambers configured to be fixed on a cylinder head and an air distributor and/or an air transfer pipe, the air transfer pipe and the air distribution chambers including, in the immediate surroundings of their nozzles, for being relatively positioned and assembled together: between the air distributor and one of the air distribution chambers, a positioning and supporting mechanism for support and precise relative centering, substantially without clearance, except for possible pivoting about the axis of engagement, once the centering has been provided along the axis, and, between the air distributor and the other air distribution chamber: an additional support mechanism and locating mechanism. A fixing mechanism locks, at the required swivel angle and in relative support, each air distribution chamber and the air distributor. | 12-10-2009 |
| 20110168120 | Modular Cross-Ram High Performance Intake Manifold for V-Type Multi-Cylinder Internal Combustion Engines - A modular intake manifold system that allows different assembly embodiments enabling different ramming effects for a V type multi-cylinder internal combustion engine. The present invention comprises a uniquely shaped runner manifold and plenum chambers for optimized airflow. | 07-14-2011 |
| 123184360 | Interconnected between plenums | 1 |
| 20100269777 | INTAKE MANIFOLDS FOR INTERNAL COMBUSTION ENGINE - Improvements in an intake manifold for an internal combustion engine having separate plenum intake storage tanks. Each plenum stores an internal large volume of air that more easily drawn into intake conduits that feed air into the intake ports of an engine. Each plenum has one or more intake ports where air is supplied from a throttle body and a plurality of intake conduits. In the preferred embodiment there are three intake conduits that provide air for a total of six cylinders. The plenums are constructed from formed pieces to provide thinner walls thereby increasing the internal volume of the plenums. The plenums further have connection ports for sensors. The intake conduits terminate a distance within the plenum and have flared ends that can be oriented towards the center of the plenum to improve air movement and flow from the input. | 10-28-2010 |
