Abstract

An exhaust system for a machine is disclosed. The exhaust system may have a diffuser configured to receive exhaust from an engine. The exhaust system may further have a plurality of dosers associated with the diffuser and configured to inject fuel into the diffuser. The exhaust system may also have a controller configured to selectively control an amount of fuel injected by each of the plurality of dosers based on a velocity of the exhaust adjacent to each doser. In addition, the exhaust system may have an after-treatment component fluidly connected downstream of the diffuser and configured to heat the exhaust by oxidizing the injected fuel.
