Abstract
In one aspect, the present disclosure is directed to a system for reacting with sulfuric acid. The system may include a housing having an inlet and an outlet and may also include a component disposed downstream of the inlet and upstream of the outlet. The component may be configured to restrict a flow of fluid through the housing as a function of sulfuric acid present within the fluid.
Claims25
A system for reacting with sulfuric acid, comprising:
- a housing having an inlet and an outlet;
- and
- a component disposed downstream of the inlet and upstream of the outlet, the component being configured to restrict a flow of fluid through the housing as a function of sulfuric acid present within the fluid.
A method for altering a flow of fluid in the presence of sulfuric acid, comprising:
- directing a flow of fluid into a housing having an inlet and an outlet;
- and
- directing the flow into contact with a component disposed downstream of the inlet and upstream of outlet;
- and
- restricting the flow through the housing as a function of sulfuric acid present within the fluid.
A power system, comprising:
- an air induction system;
- a combustion chamber located downstream of the air induction system;
- and
- an exhaust recirculation system, including:
- a filter, including:
- a housing having an inlet and an outlet,
- a filter medium disposed between the inlet and the outlet, and
- a component disposed downstream of the inlet and upstream of the filter medium, the component being configured to increase a differential pressure between the inlet and the outlet as a function of sulfuric acid passing through the filter.
A method of detecting sulfuric acid in a power system, the method comprising:
- directing a flow of air into a combustion chamber;
- directing a flow of exhaust toward the combustion chamber through a filter having an inlet, an outlet, a filter medium, and a component disposed downstream of the inlet and upstream of the filter medium;
- directing the flow of the exhaust into contact with the component;
- restricting the flow of the exhaust through the filter based on sulfuric acid in the exhaust;
- measuring a restriction value indicative of an amount of the flow restriction;
- and
- providing an indication of a flow restriction based on the restriction value.
A power system, comprising:
- a compressor to pressurize air;
- a first cooler located downstream of the compressor to cool the pressurized air;
- an engine located downstream of the first cooler and having a combustion chamber;
- an exhaust recirculation system, including:
- a turbine coupled to the compressor and being configured to rotate when acted upon by exhaust;
- and
- a filter, including:
- a housing having an inlet and an outlet,
- a filter medium disposed between the inlet and the outlet, and
- a component disposed downstream of the inlet and upstream of the filter medium, the component being configured to restrict a flow through the filter medium as a function of sulfuric acid present within the exhaust;
- a differential pressure sensor in communication with the filter and configured to generate a first signal indicative of a differential pressure of the filter;
- an indication device;
- and
- a controller in communication with the differential pressure sensor and the indication device and configured to:
- receive the first signal indicative of the differential pressure of the filter, and
- affect the operation of the indication device based on the first signal.
