Yanmar 3TNV82A – SNN Engine

Yanmar 3TNV82A – SNN is an inline three-cylinder engine with a power of 16-22 kilowatts and good torque at medium and low speeds. It adopts high-efficiency fuel injection, adapts to different fuels, meets emission standards and has low noise. It has a compact structure and high-quality and durable parts, and is used for small engineering, agricultural machinery and power generation equipment1. Power performance
Power output: The engine has a certain power and can meet the power requirements of a variety of small equipment. It can usually provide about 16-22 kilowatts of power, which makes it competent for daily operations of small excavators, loaders and other equipment, ensuring stable operation of the equipment under different working conditions.
Torque characteristics: It can output a large torque in the medium and low speed range, which can enable the equipment to obtain better power performance under working conditions such as starting and climbing, and make the equipment have stronger load capacity and work efficiency.
2. Structural design
Three-cylinder layout: The in-line three-cylinder structural design makes the engine compact and occupies a small space, which is easy to install in the limited space of small mechanical equipment. At the same time, the three-cylinder design is relatively simple, which reduces the difficulty and cost of maintenance to a certain extent.
Reasonable cylinder diameter and stroke: The design of the cylinder diameter and stroke has been optimized to ensure good combustion efficiency and power transmission, so that the engine can achieve good fuel economy while outputting power.
3. Fuel system
Fuel injection technology: Equipped with an efficient fuel injection system, it can accurately control the amount and time of fuel injection, so that the fuel and air are fully mixed, thereby improving combustion efficiency, reducing fuel consumption, and reducing exhaust emissions.
Fuel adaptability: It has a certain adaptability to fuels of different qualities, and can adapt to the fuel supply conditions in different regions to a certain extent, enhancing the versatility and practicality of the engine.
4. Environmental protection and emissions
Emission compliance: It can meet relevant environmental emission standards, such as the fourth stage emission standards for domestic non-road mobile machinery or similar strict standards abroad. By optimizing the combustion process and exhaust gas treatment technology, the emission of pollutants such as nitrogen oxides and particulate matter is effectively reduced.
Low-noise operation: During the design and manufacturing process, attention is paid to noise control, and the noise generated during operation is low, which provides a relatively quiet working environment for operators and reduces noise pollution to the surrounding environment.
5. Reliability and durability
High-quality parts: High-quality parts are selected, such as high-strength crankshafts, durable pistons, etc. These parts have undergone strict quality testing and screening to ensure the reliability and durability of the engine.
Strict testing: During the production process, it has undergone rigorous testing and verification, including long-term bench tests, actual operation tests simulating different working conditions, etc., to ensure that the engine can work stably and reliably under various harsh conditions.
6. Application areas
Widely used in small engineering machinery (such as small excavators, small loaders), agricultural machinery (such as small tractors, lawn mowers) and some small power generation equipment, providing stable and reliable power support for these equipment.
