According to the present disclosure, the internal wall assembly (36) delimits a first conduit portion (40) for conveying air to the first outlet set (16) and a second conduit portion (42) for conveying air to the second outlet set (24). Moreover, the internal wall assembly (36) is positioned in relation to the at least one exhaust gas recirculation inlet (32, 34) for distributing recirculated exhaust gases from the inlet (32, 34) towards the outlets (18, 20, 22, 26, 28, 30) via both the first conduit portion (40) and the second conduit portion (42).
Abstract:
Artificial aspiration methods and systems for increasing engine efficiency and or power. The methods include determining an engine operation status, determining an artificial aspiration goal value based on the engine operating status, determining an artificial aspiration system configuration based on the artificial aspiration goal value and the engine operating status, and configuring the artificial aspiration system to obtain the determined artificial aspiration system configuration. The system includes a plurality of sensors for sensing characteristics of an operating engine, and an artificial aspiration control unit comprising a processor connected to receive the sensed characteristics of the engine. On one example, the processor is configured to determine the engine operating status, determine an artificial aspiration goal value based on the engine operating status, determine an artificial aspiration system configuration based on the artificial aspiration goal value and the engine operating status, and configure the artificial aspiration system to obtain the determined artificial aspiration system configuration.

Abstract:
An intake system (10, 20) for a vehicle internal combustion engine is provided in which a first air intake duct (16), having an air intake inlet (16a) to inhale external air, is connected to an air cleaner box (14). A second air intake duct (17, 27) is also connected to the air cleaner box. The air intake inlet is closer to the air cleaner box than the second air intake duct is. The cross section area of a second air intake duct is greater than the cross section area of the first air intake duct. The center axis of the second air intake duct at an end on the side of a second air intake opening (12, 22) intersects with the center axis of the first air intake duct at an end on the side of a first air intake opening (11).
Abstract:
The invention relates to an air-intake system for an internal combustion engine (10) equipped with an air filter which comprises, inside an air filter housing, an uncleaned air chamber, a clean air chamber that is connected to the internal combustion engine (10), and comprises a filter insert that is arranged between the uncleaned air chamber and the clean air chamber. The uncleaned air chamber is subdivided by a partition (22) into an uncleaned air admission volume (24) and a uncleaned air discharge volume (26), whereby the size of a cross-section of the opening which is situated on the partition (22) and which is provided for the passage of uncleaned air from the uncleaned air admission volume (24) into the uncleaned air discharge volume (26) can be varied.
Abstract:
Air is fed through an auxiliary port of an internal combustion chamber at a high velocity of flow in a turbulence system. This enables mixture formation to be improved. Air flowing through the auxiliary port must be controlled. In the inventive gas flow control system, the main port gas flow (31) which circulates through the gas throttle port (34c) and the auxiliary port gas flow (12) are jointly regulated by the gas throttle (40). The gas flow control system is especially designed for automotive internal combustion engines.
