Emissions Cleaning Module

摘要

An emissions cleaning module includes a flow conduit having an upstream end fluidly connected to a source of exhaust fluid and a downstream end fluidly connected to a mixer module. An injector module has an outlet orientated to inject injection fluid into the flow conduit upstream the mixer module. A low pressure cavity downstream the injector module outlet is fluidly connected to the flow conduit or the mixer module by an open mouth orientated such that a flow of exhaust fluid along the flow conduit flows over the open mouth creating a pressure reduction within the low pressure cavity.

1. An emissions cleaning module comprising:
a flow conduit having an upstream end fluidly connected to a source of exhaust fluid and a downstream end fluidly connected to a mixer module; an injector module having an outlet orientated to inject an injection fluid into the flow conduit upstream of the mixer module; and a low pressure cavity located downstream of the injector module outlet;
wherein the low pressure cavity is fluidly connected to the flow conduit or mixer module by an open mouth, the open mouth being orientated such that, in use, a flow of exhaust fluid along the flow conduit flows over the open mouth thereby creating a pressure reduction within the low pressure cavity.
