Bus Parts - Cooling Systems - Bus Attachment Intercooler Assembly 1119-00406

The 1119-00406 Engine Intercooler Assembly is an original equipment (OE) air-to-air charge air cooler specifically designed for Yutong ZK series luxury and long-haul coaches, including models such as the ZK6122H, ZK6127HB, and ZK6119. As a core component of the engine’s forced induction system, it plays a vital role in meeting Euro V and Euro VI emissions standards by cooling compressed intake air from the turbocharger—increasing air density, improving combustion efficiency, and reducing nitrogen oxide (NOx) emissions.

Constructed from high-grade vacuum-brazed aluminum alloy, this intercooler features a tube-and-fin core design optimized for maximum heat transfer efficiency while maintaining low pressure drop across the intake path. It effectively reduces post-turbo air temperature from over 150°C down to approximately 50°C, significantly enhancing engine power output and fuel economy.
