五十铃 4HK1 turbocharger

Compatible Models: Isuzu 4HK1 series diesel engines. Compatible Equipment: Hitachi ZX200/ZX210/ZX240/ZX270 series excavators, Isuzu commercial vehicles, and other construction machinery powered by the 4HK1 engine. Main Material: Constructed from high-grade alloy cast iron resistant to high temperatures and oxidation. The housing thickness and internal flow channel structure are optimized for 4HK1 specifications, ensuring high strength and durability under harsh, high-temperature operating conditions. Impeller Response: Features a precision-cast, high-efficiency, lightweight impeller with extremely low inertia. It engages boost rapidly even at low engine speeds, significantly improving the machine's digging force and load response. Dynamic Balancing: Every unit undergoes high-speed dynamic balancing calibration before leaving the factory to eliminate micro-vibrations at high speeds, thereby extending rotor bearing life and ensuring smooth, quiet operation. Sealing Technology: Utilizes a highly reliable combination of floating bearings and seals to eliminate the risk of oil leaking into the intake tract, ensuring long-term combustion chamber cleanliness and preventing blue exhaust smoke. Installation Fit: Manufactured strictly to Isuzu OE standards. Flange hole positions, intake/exhaust flanges, and coolant/oil line connections match precisely, ensuring a "plug-and-play" fit that saves time on installation and commissioning.
