● Large specific surface area: to ensure full access to the exhaust gas with the catalyst.
● Stable water absorption: to ensure the catalyst evenly firmly attached to the surface of the catalyst carrier.
● Warm-up: after start-up the engine, the temperature of the carrier can reach the catalyst activation temperature in the shortest possible time.
● Low exhaust resistance: the engine’s exhaust resistance is small, to ensure that doesn’t affect the engine performance.
● High strength: the operating environment of the catalyst carrier is in the bumpy car, so the catalyst carrier must be high strength without being external damage.
● Good assembly: the carrier is an exhaust assembly parts, only good appearance and precise dimensions can ensure perfect assembly.
