Abstract
A solenoid valve for a pre-chamber of an internal combustion engine is provided. The solenoid valve may include a valve body defining an inlet port fluidly coupled with a fuel line, an outlet port fluidly coupled with the pre-chamber, and a passage fluidly coupling the inlet port with the outlet port. A valve stem may be slidably disposed in the passage between a first position and a second position. The valve stem may be configured to engage the outlet port in the first position to thereby prevent fluid communication therethrough. A biasing member may be disposed in the passage and configured to actuate the valve stem to the first position. A solenoid may be coupled with the valve body and configured to actuate the valve stem to the second position to thereby allow fluid communication therethrough.
