Embodiment Construction

[0017] Various features and embodiments of the inventive subject matter will appear from the following further description set forth below. According to one embodiment, the internal combustion engine (IC) described herein operates on four cycles. This IC engine is installed in a stride-type two-wheeled vehicle. It is contemplated that the concepts of the present invention may be applied to other types of vehicles that fall within the spirit and scope of the present invention. A detailed description of the constitution of parts other than the essential parts constituting the present subject matter is omitted where appropriate.

[0018] Supplying an optimal air and fuel mixture is critical to proper combustion in an IC engine. Improper mixture (lean or rich) can lead to improper combustion, affecting IC engine performance and resulting in increased exhaust emissions. Maintaining proper air and fuel mixture ratios is critical, and varying this supply ratio and rate based on IC...

Abstract

The cylinder head (204) of the internal combustion engine (101) includes two intake valves, a swirl intake valve (308) and a tumble intake valve, operating within the swirl port (501) and the tumble port (502). The charge is injected into the swirl port and the tumble port respectively through the fuel injection valve (301). The mixing region (620) into which the fuel spray is injected towards the swirl port and the tumble port is facilitated by the position of the fuel injection valve. The ratio of the vertical distance (a) between the fuel spray point (P) and the base of the port end (Y‑Y) to the cross-sectional width (E, F) of at least one of the two inlet ports is between 1.5 and 3 between. The present invention provides charge inlets from swirl ports and tumble ports to ensure adequate charge distribution and avoid unwanted engine noise.

Description

technical field [0001] The subject matter generally relates to two- or three-wheeled saddle-type vehicles. More specifically, the present subject matter relates to an air intake duct for an induction system of a two-wheeled vehicle. Background technique [0002] The air intake system plays an important role in internal combustion (IC) engines and affects drivability, providing increased mileage and generating desired torque. The sensing system includes the pressurized fuel pump, fuel injection valves, ECU, throttle valve, intake manifold, air filter, and various sensors that provide input to the ECU. The fuel injection valve introduces fuel directly inside the IC engine or inside the intake manifold in the form of a fuel spray formed by atomization of the fuel under high pressure through a small nozzle. The intake system with fuel injection has many advantages, such as cleaner and complete combustion, minimal fuel loss, higher valve sensitivity, and prevents excess fuel fr...
