Honeycomb Straightener

How to Choose the Right Honeycomb Straightener for Your Application

Exhaust flow is uneven. Straighteners guide gas to the catalyst. Cell size, wall thickness, material affect flow and pressure drop. Metallic straighteners handle high temperature, vibration, thermal cycles. Ceramic straighteners are rigid, heat slower, resist chemicals.

Install straighteners upstream of catalyst. Geometry must match engine flow and exhaust speed. Wrong design causes uneven flow, hot spots, higher back pressure, lower catalyst efficiency.

Material must tolerate peak exhaust temperatures and rapid thermal changes. Turbocharged or high-output engines often need metallic straighteners for faster light-off and lower restriction.

Straighteners must resist vibration, thermal expansion, wear. Honeycomb alignment and coating must remain intact under repeated heating and cooling.

Match straightener design to engine and exhaust characteristics. Proper design ensures uniform gas distribution, protects the catalyst, maintains emission targets over system life.
