Abstract
A V-type multiple cylinder air intake is being configured to improve the volumetric efficiency by utilizing the resonance effect while also eliminating the adverse influence of the resonance effect (residual resonance) when the engine is operating in regions of medium to high rotational speeds. The V-type multiple-cylinder air intake device has two collectors with one arranged on each bank of the V-type multiple-cylinder engine; a plurality of branch pipes extending from the collectors to a respective intake port of an opposite bank; and a plurality of crossover passages extending from the collectors to a respective branch pipes extending from the collector of the opposite bank.
