ABSTRACT:
A fuel injected engine accounts for differences in intake and exhaust path lengths between cylinders of a cylinder bank by adjusting the amount of fuel delivered to each cylinder depending upon the position of the cylinder within the bank and upon the operational condition of the engine. At low load conditions, an electronic control unit of the engine instructs the fuel injectors to inject more fuel into an upper cylinder than into a lower cylinder within the same cylinder bank. At higher load conditions, however, the fuel injectors inject equal amounts of fuel into all cylinders of the cylinder bank. The amount of fuel delivered for a given load condition desirably minimizes hydrocarbon emissions and maximizes produced torque. The engine also includes a muffler with dedicated expansion chambers for each cylinder bank. This arrangement isolates the exhaust systems associated with each cylinder bank from each other. As a result, expansion waves produced in the exhaust system of one cylinder bank generally do not interfere with or cancel out tuned wave propagation in the exhaust system of the other cylinder bank.
