ABSTRACT:
A gas injection valve of a gas engine includes a valve body having a nozzle chamber with nozzle holes for injecting fuel gas, a first gas passage for introducing fuel gas, and a second gas passage communicable at one end to the first gas passage and at the other end to the nozzle chamber. A first needle valve closes and opens communication between the first and second gas passages. A second needle valve closes and opens communication between the second gas passage and the nozzle chamber. The first and second needle valves are urged in the closing direction thereof. A hydraulic actuator opens the two needle valves. An extreme tip of the first needle valve in closed state is disposed within and exposed to the interior of the second gas passage.
