Concentric designs water pump for new Yuchai diesel.

Haldex Concentric has won the contract to design and manufacture the water pump for the new YC6K heavy-duty diesel from Yuchai, China's largest manufacturer of diesel engines for commercial vehicles. Designed in conjunction with the Austrian powertrain specialists AVL, the engine will be produced in two models, the 12.2 litre Y6K-12 and the 13 litre Y6K-13. It incorporates advanced technologies such as high-pressure common rail, SCR (selective catalytic reduction) exhaust after-treatment, Jacobs in-cylinder braking (compression release braking), 4-valve overhead camshaft and an integral cylinder head. The engine introduces a brand new cooling concept that involves a modular, symmetrical cylinder design in which the cylinder head is cooled first and then the cylinder block. Haldex Concentric employed its bespoke WPD (water pump design) software to design a pump that optimises both efficiency and cavitation performance. Based on more than 30 patents, Yuchai's YC6K series engines combine cooling technology with high strength materials, enabling the engines to meet Euro VI emission requirements while significantly prolonging the engine's lifetime.
