Abstract: A Stirling cycle machine. The machine includes at least one rocking drive mechanism which includes: a rocking beam having a rocker pivot, at least one cylinder and at least one piston. The piston is housed within a respective cylinder and is capable of substantially linearly reciprocating within the respective cylinder. Also, the drive mechanism includes at least one coupling assembly having a proximal end and a distal end. The linear motion of the piston is converted to rotary motion of the rocking beam. Also, a crankcase housing the rocking beam and housing a first portion of the coupling assembly is included. The machine also includes a working space housing the at least one cylinder, the at least one piston and a second portion of the coupling assembly. An airlock is included between the workspace and the crankcase and a seal is included for sealing the workspace from the airlock and crankcase. A burner and burner control system is also included for heating the machine and controlling ignition and combustion in the burner.

Abstract: A system and method for a combustion engine having an engine block with a V-shape, where eight cylinder passages form two banks of four passages. Each cylinder passage receives a piston from a set of pistons coupled to a crankshaft. Seven ignition devices couple to seven of the eight cylinder passages. Every 102.85 to 102.86 degrees of rotation of the crankshaft, one of the seven ignition devices trigger combustion.

Abstract: A pendulum type mount system includes a pair of upper mounts that mount upper portions of a powerplant unit on a vehicle body, and a pair of first and second lower torque rods. The first and second lower torque rods are located on opposite sides to each other with respect to a reference plane including a gravity center of the powerplant unit. A first spring constant of the first lower torque rod is not smaller than a second spring constant of the second lower torque rod. A distance between a first plane including the first lower torque rod and the reference plane is not larger than a distance between a second plane including the second lower torque rod and the reference plane.

Abstract: A forced-induction device includes a turbine wheel, a turbine housing, and a connection pipe. The connection pipe includes a partition wall that partitions the inside of the connection pipe into a first passage and a second passage. When a cross section orthogonal to a rotation axis of the turbine wheel is viewed, a line segment extending from the distal end of the partition wall toward the upstream side in the flow direction of exhaust gas and defining a boundary between the first passage and the partition wall is a first downstream line segment. A line segment extending from the distal end of the partition wall toward the upstream side in the flow direction of exhaust gas and defining a boundary between the second passage and the partition wall is a second downstream line segment. The first downstream line segment and the second downstream line segment are parallel to each other.
