An engine includes a fluid pump configured to pressurize oil and a cylinder configured to combust a mixture of fuel and air therein. The engine also includes a valve arrangement configured to deliver air or fuel and air mixture to and exhaust post-combustion gases from the cylinder. The engine additionally includes fluidly connected first and second switching mechanisms, and an oil gallery fluidly connecting the fluid pump and the second switching mechanism. The engine additionally includes an oil squirter in fluid communication with the second switching mechanism and configured to spray the pressurized oil into the cylinder. The second switching mechanism is operated by the pressurized oil to selectively activate and deactivate operation of the valve arrangement. Moreover, the first switching mechanism is configured to alternately direct the pressurized oil to the second switching mechanism to deactivate the operation of the valve arrangement and to feed the oil squirter.
