Abstract

See full text

Provided is a variable valve device for an internal combustion engine. The variable valve device includes intake- and exhaust-side swing arms that pivot to open and close intake valves and exhaust valves in two cylinders #1, #2, intake- and exhaust-side hydraulic lash adjusters that serve as pivot points of the respective swing arms, a variable valve system that continuously varies valve lift characteristics of the intake valves and lost motion mechanisms that stop opening and closing of the intake exhaust valves by lost motion of the intake- and exhaust-side hydraulic lash adjusters on the cylinder #1. The maximum valve lifts of the intake valves are set larger than valve lifts of the exhaust valves. The minimum valve lifts of the intake valves are set smaller than the valve lifts of the exhaust valves.
