Claims

[Scope of utility model registration request]

An engine comprising two high-speed intake passages in which a plurality of cylinders are assembled, and a low-speed intake passage that is formed integrally with each high-speed intake passage and opens at a connecting opening at the downstream end of each high-speed intake passage. In the intake device, a communication passage that communicates both high-speed intake passages with each other is connected to the downstream end of the high-speed intake passage, and a communication opening of the high-speed intake passage with respect to the communication passage and the low-speed intake passage are connected to the downstream end of the high-speed intake passage. An intake device for an engine, characterized in that a connecting opening to the passage is formed continuously in the longitudinal direction of the high-speed intake passage.
