Intercooler Assembly 1119010-K26B0 for Dongfeng Tianlong Renault DCI11 Engine Construction Vehicle Series

The 1119010-K26B0 Intercooler Assembly is a high-efficiency air-to-air charge air cooler specifically engineered for turbocharged diesel engines in Dongfeng medium- and heavy-duty trucks. As a critical component of the engine’s forced induction system, it cools compressed intake air from the turbocharger before it enters the combustion chamber—significantly improving volumetric efficiency, engine power output, fuel economy, and emissions performance.

Constructed from high-conductivity aluminum alloy using vacuum brazing technology, this intercooler delivers excellent thermal transfer, lightweight design, and long-term durability under harsh operating conditions. Widely used on Dongfeng Kinland (KL), Kingrun (KR), and KC series vehicles equipped with Cummins or Dongfeng Dragon Engine (DDi) platforms, the 1119010-K26B0 remains one of the most frequently replaced heat exchangers in commercial fleets as of 2026 due to its exposure to road debris, vibration, and thermal cycling.
