Yanmar 3TNV84T-GGE engine

The Yanmar 3TNV84T-GGE engine has the following performance and characteristics:
Basic parameters:
Number of cylinders: Inline three-cylinder, this structural layout is relatively compact, occupies little space, and is easy to install in small machinery or equipment.
Displacement: About 1.496L, the displacement is moderate, and it can achieve a good balance between power output and fuel economy.
Bore and stroke: The bore is 84 mm and the stroke is 90 mm. The reasonable bore and stroke design ensures good combustion efficiency and power transmission.
Weight: The dry weight is about 155 kg, which is relatively light, easy to carry and install, and will not cause excessive burden for small equipment.
Power performance:
Power and speed: The rated power can reach 30.9 horsepower (about 22.7 kilowatts), the rated speed is 3000 rpm, and the high idle speed is about 3210±25 rpm. The higher power output and speed range can meet the power requirements of a variety of small equipment.
Torque characteristics: It can output large torque in the medium and low speed range, has good load capacity and power responsiveness, and can provide stable power support whether it is in the starting, acceleration or climbing conditions of the equipment.
Fuel system:
Fuel injection method: Direct injection technology is adopted, and the mechanical fuel injection pump can accurately control the fuel injection amount and injection time, so that the fuel and air are fully mixed, the combustion efficiency is improved, and the fuel consumption is reduced.
Fuel adaptability: It has a certain adaptability to the quality of the fuel and can work normally under different fuel supply conditions, but in order to ensure the performance and service life of the engine, it is recommended to use fuel that meets the requirements.
Intake and supercharging system:
Intake method: Equipped with a turbocharger, the turbocharging technology can effectively increase the intake volume, increase the power output of the engine, and enable the engine to obtain stronger power performance at a smaller displacement.
Supercharging effect: Through turbocharging, the power performance of the engine is significantly improved. Compared with the naturally aspirated engine of the same displacement, it has a stronger power advantage and can meet the use needs of small engineering machinery, agricultural machinery and other equipment with high power requirements.
Cooling and lubrication system:
Cooling method: Liquid cooling is adopted, and heat is dissipated through the radiator, which can effectively control the temperature of the engine, ensure that the engine runs within the normal operating temperature range, and improve the reliability and service life of the engine.
Lubrication system: Forced lubrication is adopted, equipped with a trochoid pump, which can provide good lubrication for various moving parts of the engine, reduce friction and wear, and reduce the running noise of the engine.
Environmental protection and emission:
Emission standards: It meets certain environmental emission standards, and can effectively reduce the emission of pollutants such as nitrogen oxides and particulate matter during the combustion process, which is more friendly to the environment.
Exhaust gas treatment: It may be equipped with certain exhaust gas treatment devices, such as oxidation catalysts, etc., to further reduce the emission of harmful substances in the exhaust gas.
Reliability and durability:
Parts quality: High-quality parts are used, and strict quality inspection and screening are carried out to ensure the reliability and durability of the engine. For example, high-strength crankshafts, durable pistons and other parts can withstand long-term workloads.
Manufacturing process: Yanmar has exquisite manufacturing technology and strict quality control system to ensure the manufacturing quality and performance stability of the engine. The engine can maintain good operating condition even in harsh working environments such as high temperature, high humidity, and dust.
