Multi-Function Exhaust System for Diesel and Natural Gas Engines

摘要

A multi-functional exhaust system for diesel and natural gas engines includes a rectangular box housing, a selective catalytic reduction (SCR) unit, at least one reductant injector, a plurality of sensors, and a mixing duct to mix the injected reductant and the exhaust gas. A portion of the mixing duct runs in parallel beside the SCR unit reducing the overall length of the housing. Another portion of the mixing duct routes the exhaust gas through a 180 degree bend to redirect the exhaust gas to the SCR unit. The SCR unit and mixing duct are positioned within the housing and in fluid communication with an inlet and an outlet of the housing. The inlet is in fluid communication with an engine, and the outlet is in fluid communication with an exhaust outlet so that the housing can be secured as the exhaust system.

1. A multi-functional exhaust system for diesel and natural gas engines comprises:
a rectangular box housing; a passageway; a mixing duct; a selective catalytic reduction (SCR) unit; at least one nitrogen oxide (NOx) sensor; at least one temperature sensor; at least one pressure sensor; at least one reductant injector; the rectangular box housing comprises an inlet and an outlet; the inlet being in fluid communication with the mixing duct through the passageway; the mixing duct being in fluid communication with the SCR unit, wherein the mixing duct mixes the exhaust gas and the reductant agent from the at least one reductant injector; the SCR unit being in fluid communication with the outlet; and the at least one NOx sensor, the at least one temperature sensor, the at least one pressure sensor, and the at least one reductant injector traversing into the rectangular box housing.
