Abstract: In hydraulic valve last adjusters for the timing gear of an internal combustion engine comprising cylinder valve lift reversal or deactivation, said adjusters being loaded by cams of one or more camshafts while being made as a combination of switchable lash adjusters (22) and (non-switchable) standard lash adjusters, said adjusters further being configured as reverse-spring adjusters or free-ball adjusters, each adjuster comprising a control valve (32) whose closing body (41) is in the opening position during a base circle phase of the associated cam, according to the invention, the stroke of the closing body (41) of a switchable lash adjuster (22) is smaller in each case than the stroke of the closing body of a standard lash adjuster. This enables the idle strokes of the two different types of last adjusters to be adapted to each other.

Abstract: #7 cylinder shares an exhaust manifold with #1 cylinder and is fired a predetermined firing interval after #1 cylinder. An exhaust cam shaft has a first cam for driving the exhaust cams of #1 cylinder and a second cam for driving the exhaust cams of #7 cylinder. A valve overlap period of #1 cylinder during its shift from an exhaust stroke to an intake stroke overlaps a time period during which the exhaust valves of the second cylinder are open in #7 cylinder while it is shifting from a power stroke to an exhaust stroke. The nose of the second cam is located farther in a retard direction than a position that is away in the retard direction from the nose of the first cam by an angle corresponding to the predetermined firing interval between the first and second cylinders.

Abstract: A motor control device for a vehicle having a deceleration deactivatable engine which includes at least one deactivatable cylinder which is deactivated during a deceleration traveling of the vehicle, and which is started by a motor when the operation thereof transitions from a deceleration deactivation operation to a normal operation. The motor control device comprises a cylinder deactivation state determining section (S202) for determining whether or not the engine is in a cylinder deactivation state, a cylinder deactivation executing section, a cylinder deactivation operation detecting section (S201) for detecting whether or not the cylinder deactivation executing section is activated, and a starting torque setting section (S201-S204) for setting staring torque for starting the engine by the motor. When it is determined, by the cylinder deactivation state determining section, that the engine is in a cylinder deactivation state, and it is determined, by the cylinder deactivation operation detecting section, that the engine is to return to the fuel supply operation, the starting torque setting section sets a smaller staring torque than in the case of a normal operation. Accordingly, the output of the motor is optimally set when the operation transitions from the cylinder deactivation operation to the normal operation; thus, a smooth drivability and an improved fuel consumption efficiency can be obtained.

Abstract: A control device for a multicylinder spark-ignition engine includes a flow path switching unit for switching intake and exhaust flow paths between a two-cylinder interconnect configuration and an independent cylinder configuration and an air-fuel ratio control unit. In a low-load, low-speed operating range, the flow path switching unit switches the engine to the two-cylinder interconnect configuration, and the air-fuel ratio control unit produces a lean mixture having an air-fuel ratio larger than the stoichiometric air-fuel ratio by a specific amount in preceding cylinders by injecting fuel thereinto and an air-fuel ratio approximately equal to the stoichiometric air-fuel ratio in following cylinders by supplying fuel together with burned gas of a lean mixture state discharged from the preceding cylinders into the following cylinders to perform combustion in special operation mode. At engine startup, the flow path switching unit switches the engine to the independent cylinder configuration to perform combustion in normal operation mode.

Abstract: An engine system includes: a hydraulic valve stop mechanism configured to switch states of an intake valve and exhaust valve of a same stopped cylinder; a hydraulic pressure changing device configured to change hydraulic pressure supplied to the valve stop mechanism; and a valve control portion configured to control the hydraulic pressure changing device. When a return from a reduced-cylinder operation to an all-cylinder operation is requested, and an engine revolution is less than a reference revolution, the hydraulic pressure is changed such that opening of one of the valves of the stopped cylinder able to restart at an earlier stage is first restarted. When the return is requested, and the engine revolution is not less than the reference revolution, the hydraulic pressure is changed such that opening of the exhaust valve of the stopped cylinder is restarted before opening of the intake valve.
