Exhaust Apparatus TRIZ Cases

A high-density mass damper stabilizes a passive exhaust valve flap to curb resonance, flutter, and noise without adding active control.

By fixing the stop ring before cutting shaft openings, this case improves exhaust flap sealing, pivot alignment, and mechanical stability.

Elastic multi-point clamping lets the housing adapt to tolerances and rotation during stuffing, reducing support mat overpressing and shearing.

A tilted weld joint lets one exhaust connector fit different catalytic converter outlet angles, cutting part variation and assembly cost.

A straight exhaust section routed across the down frame improves exhaust gas sensor accuracy while reducing collision and vibration damage.

Crosslinked starch and acrylic polymer enable thin porous ceramic honeycomb walls while keeping extrusion pressure manageable and strength high.

Separating sensor offset calibration from catalyst state estimation improves NOx and ammonia exhaust measurement accuracy downstream of the vehicle catalyst.

A shield member on the thermoelectric module preserves temperature difference for power generation while blocking condensation shorts near connectors.

Mounting the reducing agent pump outside the body frame frees engine room space while a segmented cover and step guard protect it and ease maintenance.

Nanoparticles embedded in apertured polymer filter sheets capture contaminants while lowering cross-flow pressure drop and filter energy demand.

Radial diverter vanes split exhaust into uniform streams, cutting plume velocity and whistle noise without hurting power plant performance.

A spaced dual-layer heat shield uses insulation and an air gap to keep turbocharger surfaces below debris ignition levels.

An ECU-switched air pump feeds intake and exhaust air to speed catalyst light-off, cut cold-start emissions, and protect catalyst life.

Waste heat from a reaction tube is converted into electrical energy with a thermoelectric shell, improving recovery efficiency and cutting carbon emissions.

Standby tempering air fans let gas turbines stay SCR-compliant at part load while keeping inlet guide vanes open to cut fuel use.

Ambient air drawn through a nested exhaust outlet cools hot gases and cuts noise, while collector and duct features improve durability.

Separated internal and external vent holes keep bubbles out of the sensing area while preserving pressure balance for accurate urea tank level detection.

A side-mounted exhaust gas sensor uses U-shaped pipe routing around the down frame to simplify assembly and shield it from flying stones.

Electric heater control triggers particulate filter regeneration by soot load and exhaust temperature, cutting fuel use and emissions.

A staged noble metal distribution with milder upstream thickness gradients improves cold-start purification while limiting thermal aggregation.

A porous ceramic baffle plate improves reducing-agent atomization and evaporation in SCR exhaust flow while cutting pipe length and wear.

Radially diverging vanes split and diffuse exhaust into uniform streams, cutting plume velocity and noise without hurting plant performance.

A low-alloy titanium sheet balances cold formability with creep and oxidation resistance for vehicle exhaust parts operating up to 800°C.

Roof access doors and segmented treatment units let locomotive catalysts be replaced more easily while preserving compact exhaust aftertreatment.

A bladder-in-tank carrier transports CO2 on return trips while insulating liquefied gas and controlling pressure and temperature.

A tapered extended body and guide walls improve exhaust-treatment fluid mixing to limit deposits, lower backpressure, and support NOx reduction.

Axial sections with different flow-channel angles prevent foil damage, avoid smooth foils, and lower catalytic converter cost and heat capacity.
