Yanmar 3TNV80F-SPSY2 engine

The Yanmar 3TNV80F-SPSY2 engine has the following performance and characteristics:
Power performance:
Power output: The rated power is usually around 14.6 kilowatts (slightly different under different equipment applications). For example, on the Sany SY18U mini excavator, the engine provides stable power output for the equipment to meet the operating needs of small equipment.
Torque performance: It has good torque characteristics, with a maximum torque of 63.2-67.4 Nm/1800±100 rpm. It can output a large torque at a lower speed, so that the equipment can quickly obtain sufficient power during startup and acceleration to ensure the working efficiency of the equipment.
Structural design:
Three-cylinder layout: The in-line three-cylinder design has a compact structure and occupies a small space, which is easy to install in small engineering machinery, agricultural machinery and other equipment with high space requirements. In addition, the vibration of the three-cylinder engine is relatively small, the operation is more stable, and it can provide a more comfortable operating environment for the operator.
Reasonable cylinder diameter and stroke: The design of its cylinder diameter and stroke is relatively reasonable, which can ensure good combustion efficiency and power output.
Fuel system:
Fuel injection method: Direct injection technology is generally used to allow the fuel to be sprayed more directly into the combustion chamber, fully mixed with the air, improve combustion efficiency, and thus reduce fuel consumption. This fuel injection method can also enable the engine to maintain good power performance and fuel economy under different working conditions.
Fuel adaptability: The quality requirements for fuel are relatively low, it has good fuel adaptability, can operate stably under different fuel supply conditions, and reduces the user’s use cost and dependence on fuel quality.
Environmental protection and emissions: It can meet higher environmental protection standards, and has stricter control over exhaust emissions, reducing pollution to the environment. Its emission level usually meets the emission standards of relevant countries and regions, such as National IV and Euro V.
Reliability and durability:
Component quality: The engine components are made of high-quality materials, and undergo strict quality testing and screening to ensure the reliability and durability of the components. For example, key components such as pistons, crankshafts, and connecting rods have high strength and wear resistance, and can withstand long-term high-load operation.
Whole machine testing: During the production process, the whole machine undergoes rigorous testing and verification, including long-term operation testing, high temperature and high pressure testing, vibration testing, etc., to ensure the reliability and stability of the engine under various harsh working conditions, reduce the failure rate, and extend the service life.
Application areas: Widely used in small equipment such as small excavators, small loaders, small rollers, generator sets, and agricultural machinery
