Intake device for multiple-cylinder engine and fuel delivery pipe for intake device
Abstract:
The present invention provides an intake device and a fuel delivery pipe for a multiple-cylinder engine including a transpiration gas passage or an intake air pressure collecting passage capable of reducing the number of components and improving assembly operability. The intake device and the fuel delivery pipe for a multiple-cylinder engine include: a throttle body including a plurality of bores, each of which communicates with an inside of each cylinder of the engine, and provided with throttle valves for adjusting intake volumes inside the bores in an openable and closable manner; injectors provided in the throttle body and injecting a fuel to the bores; a delivery pipe for supplying the fuel to the injectors; and an intake pipe communication passage connected to an inside of the bores and communicating with the inside of the bores, and the intake pipe communication passage is formed integrally with the delivery pipe.
