Abstract
An internal combustion engine for a vehicle includes an engine block having a piston moveable within a cylinder bore. The piston has a piston skirt and a dome. A connecting rod operatively connects the piston to a crankshaft. A squirter is connected to the engine block and has a nozzle aimed to spray lubricant against a wall of the cylinder bore slightly below the piston skirt when the piston is at top dead center.
