Isuzu AH-6WG1XYSA-01 is rated at 348 hp. Emissions are controlled by opening and closing the Exhaust Gas Recirculation (EGR) valve installed between the exhaust manifold and intake manifold. The Engine Control Module (ECM) determines the amount of EGR, based on the engine speed and load rate the on engine (fuel injection amount), and operates the EGR valve to control the amount of EGR.
The Electronic Injectors (EI’s) send pressurized fuel through a fuel line to the fuel delivery nozzles, which are located directly over the top of the piston. The EI’s are electrically controlled by the ECM. The crankshaft position sensor and camshaft position sensor provide information to the ECM for precise fuel delivery by the electronic fuel system.
