A hybrid electric vehicle includes: an engine including a turbocharger and an intercooler that cools intake air; a motor; an inverter for driving the motor; a cooling device for cooling the inverter and the intake air by circulating a cooling medium by a circulation pump in a circulation path including a cooling flow path for cooling the inverter and a cooling flow path for the intercooler as a flow path; and a control device for controlling the cooling device. The control device permits forced drive of the circulation pump from an outside when predetermined conditions including a condition that a vehicle speed is equal to or lower than a predetermined vehicle speed and a condition that a vehicle system is turned off are satisfied.

A two-stroke engine comprises a first oiling system and a second oiling system. The first oiling system includes a low-pressure pump that distributes oil from a first oil tank to the two-stroke engine. The second oiling system includes a pump mechanically coupled to a crankshaft of the two-stroke engine, wherein the pump distributes oil from a second oil tank to an accessory at a pressure greater than the first oil pressure, wherein oil distributed to the accessory is returned to the second oil tank.

An outboard motor is provided with an upper separator disposed on the lower side of an oil case for storing a lubricating oil of an engine, and an extension case which is separably connected on the lower side of the upper separator. The upper separator has a central exhaust passage through which exhaust gas flows, and a cooling water flow part through which cooling water flows on the outside of the central exhaust passage, the central exhaust passage and the cooling water flow part forming an integrated structure. The exhaust gas and the cooling water are caused to mix in the extension case.

In general, one aspect disclosed features an in-davit run kit for a lifeboat, the kit comprising: a water container comprising a first connector; a hose configured to connect with the first connector; and a second connector configured to connect to the hose, wherein the second connector is in fluid communication with a water cooling system of the lifeboat; wherein the in-davit run kit allows a water pump of the lifeboat to draw water from the water container into the water cooling system of the lifeboat.

A motor for driving a liquid end of a pump system. The motor having an inner housing having an outer surface, a mechanical actuator disposed in the inner housing, and a water jacket surrounding at least a portion of the outer surface of the inner housing to define a volume between the inner housing and the water jacket. The volume being sized to circulate water within the water jacket so as to transfer heat from the inner housing to the water.

A cooling device includes a drain passage, a collection passage and a bypass passage each connecting an upstream portion and a downstream portion of the drain passage, a branched portion branched into the collection passage and the bypass passage, and a confluence portion joined the collection passage and the bypass passage. A difference between flowing directions from the upstream portion into the branched portion and from the branched portion into the collection passage is smaller than a difference between flowing directions from the upstream portion into the branched portion and from the branched portion into the bypass passage. A difference between flowing directions from the bypass passage into the confluence portion and from the confluence portion into the downstream portion is smaller than a difference between flowing directions from the collection passage into the confluence portion and from the confluence portion into the downstream portion.

An outboard motor cooling induction system. A pickup assembly is attached to a boat's transom proximate the keel. An uptake hose from this pickup assembly carries cooling intake water to one or more inlets on the outboard motor's lower unit. An intake plane is provided on the pickup assembly. This intake plane is preferably positioned so that the intake flow is optimized.

A combined cooling and water braking system for a vehicle comprises a first water recirculation loop having a first heat exchanger configured to cool water flowing in the first water recirculation loop, the first water recirculation loop comprising a water conduit for transporting heat away from a propulsion device configured to generate a propulsion power for the vehicle. A second water recirculation loop having a second heat exchanger is configured to cool water flowing in the second water recirculation loop. A retarder is configured to be coupled to a pair of wheels of the vehicle. The second water recirculation loop may be selectively used for cooling the propulsion device and for providing water to the retarder for water braking. There is also provided a method for cooling a propulsion device of a vehicle and water braking a pair of wheels of a vehicle.
