Tonkee Machinery Logo
Engine Model: 4BTA3.9 – C125
Number of Cylinders: 4
Type: Diesel engine
Intended Use: Commonly used in machinery applications
2. Performance Specifications
Power Output
Rated Power: 93 kW (kilowatts). This power rating allows the engine to provide sufficient energy to drive various machinery.
Rated Speed: 2200 RPM (revolutions per minute). The engine is designed to operate efficiently at this rotational speed, ensuring a balance between power generation and mechanical stability.
Torque Output
The engine is capable of delivering a maximum torque of [X] N·m (Newton – meters) at a specific engine speed. The torque curve is designed to provide good low – speed torque for efficient operation during startup and under heavy – load conditions.
3. Engine Structure
Cylinder Block
The cylinder block is made of high – quality cast iron, providing a rigid and durable structure. The cylinder bore diameter is [X] mm (millimeters), which, along with other factors, determines the engine's displacement.
Piston and Connecting Rods
Pistons are precision – machined to ensure a proper fit within the cylinders. The connecting rods are of high – strength steel, designed to transmit the force from the pistons to the crankshaft smoothly.
Crankshaft
The crankshaft is a forged steel component, carefully balanced to reduce vibrations. It converts the reciprocating motion of the pistons into rotational motion, which is then used to power the machinery.
