For Construction Machinery CAT C9 Engine Assembly 336D2 Excavator Diesel Engine

Specification

Description

Advantage

Strong Working Condition Adaptability: Delivers peak torque at low rotational speeds, adapting to heavy-load operations such as excavation and loading of excavators. It features non-sluggish power response, meeting the demands of high-intensity construction.
Outstanding Durability: Adopts a high-strength cast iron cylinder block and wet cylinder liner design, with excellent wear and deformation resistance. It is suitable for harsh working conditions such as mines and construction sites, significantly extending the service life of the whole machine.
Convenient and Efficient Maintenance: Key filters and maintenance points adopt an external layout, reducing disassembly and maintenance time. Combined with long-life lubrication and filtration systems, it has a long maintenance cycle and lowers operation and maintenance costs.
Excellent Fuel Economy: The intelligent electronic control system accurately adjusts fuel injection volume, significantly reducing fuel consumption rate while ensuring power output, balancing economy and dynamic performance.
Compliant Emission Standards: Meets mainstream emission regulations such as China Non-Road Stage III. Optimized combustion efficiency ensures compliance with particulate matter and nitrogen oxide emission control standards, adapting to construction scenarios with strict environmental requirements.

Performance

Basic Configuration: Inline six-cylinder, four-stroke diesel engine with a displacement of 8.8L, bore × stroke of 112mm × 149mm, and a compression ratio of 16.1:1.
Dynamic Performance: Rated power of 201kW (270 horsepower) @ 2200rpm, with a peak torque of up to 1250N·m @ 1400rpm, meeting the power demand for heavy-load operations.
System Configuration: Equipped with a turbocharged aftercooling system, a hydraulic electronic unit injection fuel system, and an ADEM series electronic control module for precise working condition regulation.
Capacity Parameters: The engine oil filling capacity is approximately 40L, and the cooling system capacity is 40L, adapting to the long-time continuous operation demand of excavators.
Environmental Adaptability: Can adapt to a wide temperature range of -30℃ to 50℃, with minimal power attenuation under high-altitude working conditions, suitable for construction scenarios in multiple regions.
