Claims

[Scope of utility model registration request]

A first resonance chamber that has cylinders arranged in a row and is located on both sides when viewed in the direction of the cylinder rows and communicates with a plurality of cylinders whose intake valve opening timings do not overlap, and a central portion when viewed in the direction of the cylinder rows. a second resonance chamber in which a plurality of cylinders whose intake valve opening timings do not overlap communicate with each other, and a third resonance chamber in which the first and second resonance chambers communicate with each other on the upstream side when viewed in the intake flow direction; In an intake system for a multi-cylinder engine in which intake air supercharging is carried out using intake pulsation pressure, the first and second resonance chambers are arranged vertically one on top of the other, and the second resonance chamber is The first resonant chamber is formed narrower than the first resonant chamber, and the widthwise central portion of the first resonant chamber is moved away from the cylinder, and a fuel injection nozzle is attached to the downstream end portions of the first and second resonant chambers. Intake system for multi-cylinder engines.
