Abstract
An internal combustion engine system includes a first set of cylinders, a second set of cylinders, exhaust manifolds, and exhaust gas sensors. The first set of cylinders has first and second subsets of cylinders. The second set of cylinders has third and fourth subsets of cylinders. The exhaust manifolds have primary conduits, secondary conduits branching from the primary conduits, and tertiary conduits branching from the secondary conduits. The tertiary conduits associated with each of the secondary conduits are connected to one of the first, second, third, or fourth subsets of cylinders. The exhaust gas sensors are disposed within each of the secondary conduits and are each configured to measure air-to-fuel ratios of one of the first, second, third, or fourth subsets of cylinders.
