摘要

A variable compression ratio engine (100). The engine includes a piston (21) disposed in a cylinder bore and constituting a combustion chamber (23), a variable compression ratio mechanism (10) connected to the piston (21) and causing a top dead center position of the piston to vary, an actuator (42) connected to the variable compression ratio mechanism (10) to actuate the variable compression ratio mechanism (10), and a controller (50) connected to the actuator (42) to control an engine state and the actuator (42). The controller (50) performs operations including setting the compression ratio corresponding to a state of the engine (100), actuating the actuator (42) so that the compression ratio is set, determining whether a state of the engine (100) is either a state allowing actuation of the actuator (42), or a state limiting actuation of the actuator (42), and limiting actuation of the actuator (42) in the state limiting actuation of the actuator (42).
