Abstract: Provided is a carbon dioxide removal apparatus capable of reducing heat loss that can be caused when carbon dioxide is desorbed from an adsorbent. The carbon dioxide removal apparatus includes a frame, and an adsorption-desorption part supported by the frame. A clearance is provided between the frame and the adsorption-desorption part, and an air guide having flexibility is provided in the clearance.

Abstract: Provided is a carbon dioxide removal apparatus that enables determination of whether or not carbon dioxide has desorbed from an adsorbent without using a carbon dioxide sensor. A carbon dioxide removal apparatus includes a carbon dioxide adsorption module, a first valve provided in an intake part of the carbon dioxide adsorption module, a second valve provided in a discharge part of the carbon dioxide adsorption module, a third valve connected to the discharge part, a vacuum pump connected to the carbon dioxide adsorption module via the third valve, and a controller. The carbon dioxide adsorption module includes a pressure meter and an adsorbent, and the controller is configured to perform, based on a pressure measured by the pressure meter, at least one of determining whether carbon dioxide has desorbed from the adsorbent or detecting an abnormality.

Abstract: The method includes in succession a first step of assembling a power unit into a sub-frame in almost the same position as in a mounted state on a car body frame by interposing a torque rod and at least two on-board mounts between the power unit and the sub-frame; a second step of attaching the sub-frame on which the power unit is mounted to the car body frame; and a third step of supporting the power unit via a power source side mount and a speed reducer side mount on the car body frame.

Abstract: The method includes in succession a first step of assembling a power unit P into a sub-frame SF in the almost same attitude as in a mounted state on a car body frame F by interposing a torque rod 67 and at least two on-board mounts 71, 81 between the power unit P and the sub-frame SF, a second step of attaching the sub-frame SF on which the power unit P is mounted to the car body frame F, and a third step of supporting the power unit P via a power source side mount 16 and a speed reducer side mount 17 on the car body frame F.

Abstract: An engine including an engine oil return passage for returning engine oil from a cylinder head side to an oil pan having a balance shaft forming a balancing system for said engine; and a housing disposed below a crankshaft for accommodating rotatably therein the balance shaft. A part of the engine oil return passage is provided in the housing.

Abstract: An engine including an engine oil return passage for returning engine oil from a cylinder head side to an oil pan (5) has: a balance shaft (13L, 13R) forming a balancing system (4) for said engine; and a housing (14U, 14L) disposed below a crankshaft (1) for accommodating rotatably therein said balance shaft (13L, 13R). A part (142) of said engine oil return passage is provided in said housing (14U, 14L).
