  "textContent": "An internal combustion engine with at least two rotatable bodies each defining at least one combustion chamber of variable volume and, for each rotatable body: a pilot subchamber, a pilot fuel injector (78) having a tip in communication with the pilot subchamber, an ignition element positioned to ignite fuel within the pilot subchamber, and a main fuel injector (42) spaced apart from the pilot fuel injector. The engine includes a common first fuel conduit (302) in fluid communication with each main fuel injector (42), and a common second fuel conduit (304) in fluid communication with each pilot fuel injector (78). First and second pressure regulating mechanisms (322,318) which are settable at different pressure values from one another respectively regulate a fuel pressure in the first and second conduits (302,304).",
