Engine Model: 4HK1 - XDHAG - 01 - C3
Application: For ZX240 - 3 and ZX250 - 3 excavators
Type: 4 - cylinder diesel engine assembly
Performance Specifications
Power Output
Rated Power: 140 kW. This power level enables the engine to provide sufficient energy to drive the excavator's hydraulic and mechanical systems, allowing it to perform heavy - duty digging, lifting, and other operations.
RPM (Revolutions per Minute)
Rated Speed: 2000 RPM. The rotational speed is optimized to balance power output and fuel efficiency. At this speed, the engine can efficiently convert fuel energy into mechanical work to operate the excavator.
Mechanical Specifications
Cylinder Configuration
Number of Cylinders: 4. A four - cylinder configuration provides a relatively smooth power output and better balance compared to fewer - cylinder engines. The cylinders work in a coordinated manner to deliver the required torque and power.
Dimensions (Approximate)
Length: [Length value] mm. The length affects the engine's fit within the excavator's engine compartment and also influences the overall layout of other components around it.
Width: [Width value] mm. The width is designed to fit within the available space in the excavator while also allowing for proper installation of accessories such as the fuel injection system and air intake.
Height: [Height value] mm. The height is crucial for clearance within the engine bay and to ensure that components such as the exhaust system and valve cover have enough space.
Weight
Dry Weight: [Weight value] kg. The weight of the engine affects the overall weight distribution of the excavator and also impacts transportation and installation requirements.
Fuel System Specifications
Fuel Type
Diesel Fuel: The engine is designed to run on diesel fuel. It typically requires a specific grade of diesel, such as a standard commercial diesel fuel with appropriate cetane number and viscosity to ensure efficient combustion.
Fuel Consumption
Fuel Consumption Rate: Under normal operating conditions (e.g., at a specific load factor), the fuel consumption might be around [X] liters per hour. This value can vary depending on the workload and operating mode of the excavator.
Fuel Injection System
The engine likely uses a high - pressure common - rail fuel injection system. This system precisely controls the injection timing and quantity of fuel into each cylinder, improving combustion efficiency and reducing emissions.
