Advanced Power System & Stable High-Efficiency Performance
Adopting four-cylinder in-line, water-cooled, direct injection structural design, equipped with high-pressure common rail fuel injection technology, the fuel atomization effect is excellent, combustion is more sufficient, and power output is stable and continuous. With a displacement of 3.053L, the power range covers 34.9-56kW, matching the working needs of small excavators and loaders perfectly, and the maximum torque reaches 217N·m at 1800rpm, with strong low-speed torque and excellent overload capacity. Even under heavy-load continuous operation conditions such as excavation, shoveling and handling, it can maintain stable power output, no power attenuation, and efficiently support the efficient operation of construction machinery.
Compliance with Multiple Emission Standards & Eco-Friendly Low Pollution
This engine is independently developed and optimized by YANMAR, fully complying with Euro II, China III and China IV national emission standards, perfectly adapting to global and domestic environmental protection requirements for construction machinery. The optimized combustion system and emission control technology effectively reduce the emission of harmful substances such as particulate matter and nitrogen oxides, realizing green and low-carbon operation. It can pass the environmental protection inspection of various regions smoothly, avoiding the use risk caused by substandard emissions, and adapting to the construction standards of domestic and overseas engineering projects.
Water-Cooled Heat Dissipation & Adapt to Harsh Working Conditions
Adopting efficient water-cooled circulation heat dissipation system, matched with optimized heat dissipation channel design, it can quickly conduct the heat generated by long-term operation, avoiding engine overheating failure caused by continuous high-load work, dust covering and high-temperature construction environment. Whether it is outdoor construction in high-temperature summer, or long-time continuous operation in closed construction space, the engine can always maintain a stable working temperature, effectively protecting internal components, reducing wear and tear caused by high temperature, and adapting to various harsh construction scenarios such as urban renovation, rural engineering and mine auxiliary operation.
Low Fuel Consumption & Low Failure Rate, Cost-Effective
Relying on YANMAR’s top fuel injection control technology and optimized mechanical structure, this engine achieves a balance between high power and low fuel consumption, fully improving fuel utilization rate and reducing daily operating fuel costs for users. Meanwhile, the durable and high-strength internal components, coupled with precision assembly technology, greatly reduce the probability of common failures such as oil leakage, air leakage and abnormal noise. The later maintenance is simple and convenient, with low maintenance costs and long overhaul cycle, effectively reducing the comprehensive use cost of equipment throughout the life cycle, bringing long-term cost benefits to engineering owners and operators.
Perfect After-Sales Adaptability & Abundant Accessory Supply
As a classic model of YANMAR small diesel engine, the 4TNV94L engine has a very mature market application system, and the supporting maintenance accessories are complete and easy to purchase, with no shortage of accessories or high cost of spare parts. The engine structure is designed reasonably, with simple disassembly and assembly, convenient daily maintenance and repair operations, and general engineering machinery maintenance stations can complete routine maintenance and fault repair. It is very friendly to both large engineering teams and individual equipment owners, solving the worries of later use and maintenance, and ensuring long-term stable operation of equipment.
