مجموعة الأسطوانات Hino مجموعة المحرك الأساسية J08 لـ آلات البناء

The Hino J08 series engine stands out as a premier power source for Japanese construction machinery, renowned for its exceptional fuel efficiency, outstanding reliability, and remarkably smooth power delivery. As a large-displacement, inline-six-cylinder diesel engine, it performs exceptionally well in the 20-to-30-ton excavator class. Its "Bare Engine Assembly" typically comprises core components such as the cylinder block, cylinder head, crankshaft, connecting rods, pistons, and camshaft.

Engine Configuration: Inline-six-cylinder, 4-stroke, 7.684-liter displacement

Cooling System: High-efficiency water-cooling system (featuring superior thermal load management)

Air Intake System: Turbocharged and intercooled (ensuring consistent power output under high-load conditions)

Rated Power: Approximately 150–210 kW (200–280 hp), depending on specific equipment calibration

Fuel System: Electronically controlled common-rail fuel injection system (delivering high injection precision to optimize emissions and fuel economy)

Key Advantages:

Superior Power Response: Delivers smooth power output and rapid response amidst the complex load fluctuations of excavation work, effectively boosting operational efficiency.

Outstanding Durability: Hino engines are renowned for precision manufacturing, offering excellent wear resistance in the cylinder block and critical moving parts.

Fuel Economy: The application of high-pressure common-rail technology significantly reduces operating costs during long-duration operations.

Primary Applications: Kobelco excavators, Sumitomo construction machinery, large industrial generator sets, and specialized heavy-duty vehicles.
