Abstract
An oil injection system for two-stroke engines, including a pressure regulator located within an oil reservoir, the pressure regulator selectively returning a portion of pumped oil directly back to the oil reservoir to prevent oil from exiting the reservoir at a higher than desired pressure. The pressure regulator allows a portion of the pumped oil from the oil reservoir to flow through the oil line to a solenoid valve, where the pressure regulator and solenoid valve together meter the flow of oil to a plurality of oil injectors for injection into the engine cylinders. Locating the pressure regulator within the oil reservoir eliminates the need for a return line from the solenoid valve to the oil reservoir, thus simplifying the solenoid design as well as the overall design of the oil injection system.
