ジン。 A combustion chamber cavity recessed in the top of the piston, a fuel injection nozzle that injects fuel into the combustion chamber cavity when the piston reaches near the top dead center of the compression stroke, and a fuel injection nozzle that injects fuel into the combustion chamber cavity. The duty ratio of the current supplied to the glow plug is determined based on the engine exhaust gas temperature, the CO 2 concentration in the exhaust gas, and the cylinder internal temperature. An engine characterized by detecting and controlling at least one gas pressure.
