  "textContent": "An efficient engine combustion system with multiple combustion modes, includes a valve actuating mechanism, a pre-combustion chamber (), and a main combustion chamber. The valve actuating mechanism is a fully variable valve mechanism; an intake valve () and an exhaust valve () are driven by high-pressure oil; ignition is implemented by means of an ignition apparatus of the pre-combustion chamber (); and a spark plug () and a single-hole fuel injector () are mounted in the pre-combustion chamber (), a bottom end of which is provided with a flame jet hole. The air inlet valve () and the exhaust valve () are respectively mounted thereon with an air inlet valve spring () and an exhaust valve spring (); and the air inlet valve spring () and the exhaust valve spring () are separately connected to a hydraulic piston () that has an ejector rod; and the opening and closing of the air inlet valve () and the exhaust valve () are performed by the hydraulic piston (). The efficient engine combustion system with multiple combustion modes may achieve smooth transition between different combustion modes, thus ensuring that the engine has optimal thermal efficiency under different operating condition regions.",
