QSNT-C345
Cummins
The Cummins QSNT-C345 is a robust 14-liter, in-line six-cylinder diesel engine designed to deliver reliable, high-torque power for the most demanding industrial and construction equipment. As part of the proven QSNT series, this 345 horsepower engine combines electronic precision with mechanical durability to meet stringent emission standards while providing efficient and cost-effective performance in challenging environments.
The QSNT-C345 is engineered as a prime mover for heavy-duty, continuous-use equipment. Its primary and most common application is powering large crawler bulldozers, where its high torque and durability are essential:
Major Bulldozer Models: This engine is the specified power source for several leading heavy-duty bulldozers, including the Shantui SD32, SD32-C5, and the TY320H.
Industrial Sectors: These machines, powered by the QSNT-C345, are indispensable in sectors such as mining, large-scale earthmoving, road and port construction, forestry, and major infrastructure projects.
1. CELECT Electronic Fuel System for Performance and Economy
The engine is equipped with a Cummins CELECT electronic fuel injection system. This technology allows for precise control of injection timing and fuel quantity, optimizing combustion. The result is excellent fuel efficiency, responsive power delivery, and reliable compliance with Stage IIIA/Tier 3 emissions standards without the need for complex after-treatment systems.
2. Robust Design for Maximum Durability and Uptime
Built on a proven heavy-duty platform, the QSNT-C345 incorporates durable components to withstand the high-stress cycles of bulldozer operation. Features such as the radial sealing intake system are designed to effectively keep out contaminants, significantly enhancing the engine's service life and reliability in dusty, harsh job site conditions.
3. High Torque Output for Demanding Loads
Engineered to deliver a high torque rise, the engine produces its peak torque of 1509 N·m at a low 1400 RPM. This characteristic provides exceptional lugging power and "push-through" ability, allowing equipment to maintain momentum and productivity when tackling heavy loads, steep gradients, or tough materials without stalling.
4. Simplified Maintenance for Lower Operating Costs
The engine's design prioritizes serviceability to minimize downtime. Its electronic system facilitates quick diagnostics, and the robust mechanical layout ensures that routine maintenance is straightforward. This focus on ease of service contributes directly to a lower total cost of ownership over the engine's long operational life.
