Yanmar 3TNV88F – ESSY Engine

Yanmar 3TNV88F – ESSY is an inline three-cylinder engine with a power of 20-25 kW and high torque at low and medium speeds. It adopts advanced fuel injection, adapts to different fuels, meets emission standards and has low noise. It has a compact structure and high-quality and durable parts. It is used in small engineering, agricultural machinery and power generation equipment.
1. Power performance
Power output: The engine has good power output performance and can provide stable and relatively strong power for the adapted equipment. Its maximum power can generally reach about 20-25 kilowatts, which can meet the operating needs of small excavators, loaders and other construction machinery under different working conditions, such as sufficient power when digging loose soil and loading small cargo.
Torque performance: It has high torque output in the medium and low speed range, which can make the equipment easily cope with working conditions such as starting and climbing, and enhance the load capacity and working efficiency of the equipment. Usually, it can output a large torque at 1500-2000 rpm to ensure stable operation of the equipment in complex working scenarios.
2. Structural design
Three-cylinder layout: It adopts an in-line three-cylinder design with a compact structure and small footprint, which is easy to install in various small mechanical equipment. This design is not only conducive to the overall layout of the equipment, but also reduces the weight and volume of the equipment, and improves the maneuverability and flexibility of the equipment.
Reasonable cylinder diameter and stroke: The cylinder diameter and stroke are carefully designed to ensure good combustion efficiency and power transmission. This design enables the engine to more effectively convert fuel energy into mechanical energy during operation, improving energy utilization efficiency.
3. Fuel system
Fuel injection technology: Equipped with an advanced fuel injection system, it can accurately control the fuel injection amount and injection time, so that the fuel and air are fully mixed to achieve efficient combustion. This helps to reduce fuel consumption, improve the economy of the engine, and reduce exhaust emissions, meeting environmental protection requirements.
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, reducing users’ concerns about fuel quality and improving the versatility and practicality of the engine.
4. Environmental protection and emissions
Emission compliance: It can meet strict environmental emission standards, such as the fourth stage emission standards for domestic non-road mobile machinery or similar standards abroad. By optimizing the combustion process and adopting advanced exhaust treatment technology, the emission of pollutants such as nitrogen oxides and particulate matter is effectively reduced, reducing pollution to the environment.
Low-noise operation: Pay attention to noise control during the design and manufacturing process, and the noise generated during operation is low, providing operators with a relatively quiet working environment, while also reducing 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 inspection and screening to ensure the reliability and durability of the engine.
Strict testing: During the production process, a large number of rigorous tests and verifications have been carried out, 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, reduce the occurrence rate of failures, and extend the service life.
6. Application areas
Widely used in small construction machinery (such as small excavators, small loaders), agricultural machinery (such as small tractors, lawn mowers) and some small power generation equipment, etc., to provide stable and reliable power support for these equipment.
