工程机械 的 发动机 Mitsubishi 4D34

Mitsubishi 4D34 Engine: A highly durable and powerful 4-cylinder, water-cooled diesel engine frequently found in medium-duty trucks, industrial machinery, and construction equipment. Known for its rugged construction and exceptional reliability, the 4D34 is often favored for applications requiring consistent power under heavy loads.

Engine Configuration: Inline 4-cylinder, 4-stroke, 3.9L (3,907cc) displacement.

Cooling System: Liquid-cooled.

Rated Power: Typically ranges from 80 – 115 kW (107 – 154 hp) depending on the variant (naturally aspirated or turbocharged).

Fuel System: Mechanical direct injection (often found with a reliable inline fuel injection pump).

Key Advantage: Renowned for longevity and high torque output at lower RPMs; it is relatively simple to maintain, which is a major advantage for equipment operating in remote or demanding environments.

Primary Applications: Mitsubishi Fuso trucks, various construction excavators (often Kobelco), loaders, and stationary power units.
