Abstract
An internal combustion engine cooling device, comprising: a cylinder, having a lower end with an oil reservoir containing oil; a piston, moving inside the cylinder; and a crankshaft, mounted on the lower end of the cylinder. The crankshaft is connected to the piston, performing a rotating movement, further having several counterweights which take part in the rotating movement and partly dip into the oil during the rotating movement. Each of the counterweights has an oil reserve duct, which ends in an oil duct inlet and an oil exit and dips into the oil during the rotating movement. Thus oil is allowed to enter the oil reserve duct through the oil duct inlet, undergoing a centrifugal force and being splashed out through the oil exit, such that the cylinder and the piston are cooled and lubricated.
