An engine assembly includes an engine, an external oil reservoir, a supply pump, and a return pump. The engine includes an oil gallery configured to distribute oil and a crankcase chamber. The external oil reservoir includes an oil tank defining an oil chamber and an oil filter assembly including a housing at least partially defining a filter chamber, and a filter positioned within the filter chamber. The supply pump is in fluid communication with the oil chamber and the oil gallery and the supply pump is configured to draw oil from the oil chamber and provide pressurized oil to the oil gallery. The return pump in fluid communication with the crankcase chamber and the filter chamber and the return pump is configured to draw oil from the crankcase chamber and provide pressurized oil to the filter chamber.

An engine unit includes an engine body, a crankshaft, and an oil tank. The engine body includes a cylinder unit and a crankcase. The crankshaft is accommodated in the crankcase and extends in the horizontal or substantially horizontal direction. The oil tank is located at a lateral portion of the engine body. The oil tank includes a tank body, a first component, and a second component. The first component is separate from the tank body and is joined to the tank body. The second component is separate from the tank body and is joined to the tank body. A first joint surface between the tank body and the first component extends in a direction different from that of a second joint surface between the tank body and the second component.

An oil level sensor assembly for an oil tank includes a cell with a first set of holes along the cell, an oil level sensor within the cell that is configured to be inserted into and removed from a bottom of the cell, and a ball valve column within the cell and adjacent to the oil level sensor. The ball valve column is rotatable, has ball valves that correspond with the first set of holes along the cell, and is configured such that the ball valve column is rotatable to an open position aligning the ball valves with the first set of holes to allow oil to access the oil level sensor and rotatable to a closed position misaligning the ball valves with the first set of holes to prevent oil from accessing the oil level sensor.

A method is described of controlling at least one operation in at least part of a lifecycle of a replaceable container which is arranged to be removably seated in a dock in a vehicle and which at least before seating in the dock contains an ancillary fluid for use by the vehicle. A controller communicates with a data carrier carried by the container, determines, on the basis of the communication with the data carrier, data associated with at least one of the container, its contents and the vehicle, and controls carrying out of at least one action in relation to at least one of the container and its contents on the basis of the data associated with at least one of the container, its contents and the vehicle.

A method is described of supplying liquid to a liquid delivery system in a vehicle. A a replaceable liquid container including a reservoir containing liquid is releasably coupled in the vehicle to provide fluidic communication between the reservoir and a liquid delivery system of the vehicle during operation of the vehicle. The method includes the steps of : (i) prior to establishing liquid communication between the reservoir and the liquid delivery system of a selected vehicle, communicating with a data carrier carried by the container and determining data associated with at least one of the container and its contents; and(ii) using the data in an analysis of suitability of the container and/or content of the container for the selected vehicle and generating a suitability output, and(iii) establishing liquid communication between the reservoir and liquid delivery system of the selected vehicle in dependence on the suitability output.

A tank stores a coolant liquid and an engine and/or transmission lubricant for a motor vehicle heat engine, as well as a circuit for the cooling and heat regulation of that engine.

The tank has a thermally insulating outer wall including an inlet and an outlet for this liquid, and inside the wall, it comprises heating means that are able to preheat this liquid for the cold engine start of the vehicle.

The tank further includes a first compartment for this liquid that is provided with said inlet and said outlet, and at least one other compartment that is appropriate for storing an engine or transmission lubricant and that is separated from the first compartment by a tight partition in a lower zone of the first compartment, these compartments each containing at least one local heating means as heating means.
