Air intake port for lean-burn gasoline engine
The patent US12044192B2 presents a novel air intake port designed specifically for lean-burn gasoline engines. The air intake port features an air inlet, two air outlets, and an air channel that connects the inlet to the outlets. This channel consists of an upstream common duct and two downstream port legs that branch off at a bifurcation point. A key aspect of the design is the gradual decrease in the total cross-section of the air intake port from the inlet to the outlets, with a notable reduction in the gradient of this decrease in the region adjacent to the bifurcation point. The claims detail various configurations of this gradient, including instances where it may be approximately zero or even negative in specific areas, which could enhance airflow dynamics.
Further claims elaborate on the characteristics of the air channel, emphasizing the importance of maintaining a controlled gradient of decrease in cross-section. The patent outlines scenarios where the gradient is at least 20% or 40% below the average in certain regions, particularly near the bifurcation point. Additionally, it describes how the gradient may increase downstream of this region or remain constant in specific areas. The invention is applicable not only to lean-burn gasoline engines but also to vehicles and other lean-burn engine configurations, indicating its potential for improving engine efficiency and performance through optimized air intake design.
