HIGH OUTPUT ENGINE AND VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a high output engine capable of maintaining high output at ordinary time and capable of exhibiting enhanced transient output responsiveness and exhaust emission characteristics and a vehicle equipped with it. SOLUTION: A partitioning wall length L is set so that a ratio X of the partitioning length L of an intake port 20 and an inter-central distance D of an adjacent suction valve is 0.45 or more and 0.72 or less. An injector 30 is mounted on the upper side of the throttle body 21. An attached angleϕof the injector 30 is set in 42°≤ϕ≤55°. The injection start time of the injector 30 is set while the suction valve is closed. COPYRIGHT: (C)2006,JPO&NCIPI
