CAT Caterpillar engine 328-5574, a mature power unit, is widely used in medium-sized construction machinery (such as excavators, loaders) and 75-100kVA generators with efficient and stable performance. It adopts an inline 4-cylinder design, 4.4L displacement, rated power 86kW@2200rpm, maximum torque 450N·m@1400rpm. Equipped with a high-pressure common rail fuel system for precise injection, it achieves over 92% combustion efficiency, fuel consumption as low as 205g/kW·h, and meets EPA Tier 3 emissions standards, adapting to multi-condition operations.
The engine block is cast from high-strength gray cast iron, with nitrided cylinder liners improving wear resistance by 30%; the piston is forged from aluminum alloy with integrated cooling oil channels, capable of withstanding continuous high temperatures (maximum in-cylinder temperature 1800℃) and alternating loads. Its mean time between failures (MTBF) reaches 3000 hours, suitable for continuous heavy-duty work. The modular design simplifies daily maintenance—key components (filters, belts, sensors) can be replaced without complex disassembly, improving maintenance efficiency by 40%.
Ningbo Qiuning Trading Co., Ltd. provides comprehensive parts support for this model, including original and aftermarket options: Original parts (e.g., fuel filters, injectors, water pumps) strictly follow Caterpillar specifications, each batch tested for performance to ensure perfect matching, suitable for scenarios requiring high equipment reliability; Aftermarket parts pass 1000-hour installation verification, with key dimensions and materials up to standard, priced at 50%-65% of original, covering core daily maintenance parts for budget control needs.
It is recommended to replace oil and filters every 500 hours, and check turbocharger tightness every 1500 hours. We stock 80% of common parts, supporting global delivery within 48 hours, with technical team providing installation guidance and fault diagnosis. Welcome to consult for suitable parts:
