The present invention is directed to compositions with solvent, wax and graphene. These compositions offer surprising benefits in reducing bicycle or motorbike chain lengthening, particularly in off road environments with high dirt and water levels such as during mountain biking or off-road biking. The invention is further directed to a method of preparing such compositions and to the use of such compositions on bicycle or motorbike chains.

An air/oil-cooled internal combustion engine capable of increasing accuracy in detection of the temperature of the air/oil-cooled internal combustion engine by a temperature sensor and carrying out the warm-up operation after the start-up of the air/oil-cooled internal combustion engine favorably. The air/oil-cooled internal combustion engine includes cooling fins that are provided on the circumferences of a cylinder block and a cylinder head; and a cooling passage that is provided in a combustion chamber upper wall covering a combustion chamber of the cylinder head and is used for cooling the combustion chamber upper wall with lubrication oil. The air/oil-cooled internal combustion engine has a temperature sensor configured to detect the temperature of the air/oil-cooled internal combustion engine by detecting the temperature of oil. The temperature sensor faces a cooling oil outlet portion of the cooling passage.

A device for applying oil on a chain of a two-wheeler, such as a bicycle (10), comprises: a container for the oil to be applied; an outlet through which the oil may exit from the container; and an applicator configured to repeatedly open and close the outlet during a movement of the device relative to the chain in the longitudinal direction of the chain so that the oil located in the container is applied incrementally to the chain.

The present disclosure provides systems, devices and methods for using an oiling tool that allows the mechanic to apply a stream of atomized spray of oil to the top of the inner links of a motorcycle chain and on both sides as the chain is turned along with the motorcycle wheel.

A lubricant supply system for a motor vehicle, in particular a single-track motor vehicle, includes a lubricant pump configured to convey a lubricant for lubricating engine components in a lubricant circuit of the motor vehicle, and optionally a lubricant filter configured to filter the lubricant conveyed in the lubricant circuit. The lubricant filter is directly attached to the lubricant pump, and/or an imaginary continuation of a pump shaft of the lubricant pump crosses the lubricant filter, and/or at least two lubricant pumps are provided, and the at least two lubricant pumps are driven by a common pump shaft.
