INTAKE DEVICE OF A VEHICLE ENGINE FOR REPRESSING OPERATION NOISE OF A THROTTLE BODY FROM LEAKING OUT OF A CLEANER CASE BY INSERTING THE THROTTLE BODY IN THE CLEANER CASE

摘要

PURPOSE: An intake device of a vehicle engine is provided to prevent the rainwater from contacting directly to a throttle body and to cut off operation noise of an injector in a cleaner case by receiving the injector in the cleaner case. CONSTITUTION: In an intake device of a vehicle engine, a cleaner case(50A) is divided into a non-purified chamber(51A) and a purified chamber(52A). An air cleaner(29A) receives a cleaner element(53) for filtering the air which flows from the non-purified chamber to the purified chamber. A throttle body(48) controls the amount of the air supplied from the purified chamber to cylinder heads(28F,28R). The throttle body is received in the cleaner case. A portion of the non-purified chamber functions as an intake chamber(66A). Throttle cables(64,65) extended from the throttle body is drawn outward through a portion contacting to the non-purified chamber of the cleaner case.
