Abstract
An oil squirter includes a housing in fluid communication with a source of oil pressure, a first nozzle in fluid communication with the housing, and a second nozzle in fluid communication with the housing. The oil squirter also includes a mechanism arranged within the housing and configured to open the first nozzle and close the second nozzle when the oil pressure is below a threshold value. The mechanism is also configured to open the second nozzle and close the first nozzle when the oil pressure is at or above the threshold value. An engine having a cylinder defined by a cylinder bore, a piston configured to reciprocate within the cylinder bore, and the oil squirter, along with a vehicle having such an engine, is also disclosed. In the engine, the first nozzle sprays oil onto the cylinder bore and the second nozzle sprays oil at the underside of the piston.
