A method of controlling a diesel engine connected to a load, the method including the steps of detecting an increased torque requirement and matching a fuel flow with an airflow. The detecting an increased torque requirement step detects an increased torque requirement for the engine, the increased torque requirement taking place during a period of time. The matching a fuel flow step matches a fuel flow with an airflow going to the engine during the increased torque requirement, the matching step keeps the airflow and the fuel flow during the period of time at a substantially stoichiometric level enabling the use of a three-way catalyst to reduce NOx emissions during transients.

NOx control during load increases

An exhaust component arrangement is provided for an off-road vehicle having an engine, a cab, a transmission connected to the engine, and a fuel tank adjacent the transmission. A portion of the fuel tank is positioned below a portion of the cab. The exhaust component arrangement includes a particulate filter unit, a NOx reduction unit, and an oxidation catalyst unit, all connected in series. The fuel tank has a recess formed in an upper surface thereof. A lower portion of one of the units is received in the recess. Preferably, a lower portion of the NOx reduction unit is received in the recess.

Vehicle exhaust component arrangement

An internal combustion engine includes a turbocharger having a turbine, a first set of combustion cylinders, and a second set of combustion cylinders. A first particulate trap is in fluid communication between the first set of combustion cylinders and the turbine. A second particulate trap is in fluid communication between the second set of combustion cylinders and the turbine.

Internal combustion engine with dual particulate traps ahead of turbocharger

An internal combustion engine includes a first set of combustion cylinders and a second set of combustion cylinders. A first exhaust manifold is associated with the first set of combustion cylinders, and a second exhaust manifold is associated with the second set of combustion cylinders. A turbocharger includes a turbine which is fluidly coupled exclusively with the first exhaust manifold. An EGR system fluidly interconnects the second exhaust manifold and an intake manifold.
