Reliable and Safe Performance

The X6170 series uses a reinforced block, crankshaft, and connecting rods to ensure a major overhaul interval of more than 20,000 hours. Moreover, Weichai’s global supplier network keeps every key component dependable. The engine also features a high-flow lubrication system with pre-filtration and efficient cooling. Its modular layout and single-cylinder-head design make daily service quicker and more convenient.

Strong and Responsive Power

Weichai optimizes the high-pressure fuel pump, turbocharger, injector, valve system, and combustion chamber to deliver strong output across a wide power band. As a result, the X6170 series provides more than 30% torque reserve, giving vessels powerful acceleration and stable thrust even under heavy load.

Fuel-Efficient Operation

With a four-valve configuration and pulse-conversion turbocharger, the engine draws in more air and burns fuel more completely. Therefore, it maintains an efficient operating range and reaches a minimum fuel consumption rate of about 191 g/kW·h, helping ship owners lower long-term running costs.

Comfortable and Environment-Friendly

Weichai enhances critical components to reduce vibration levels to Class A of Grade 11. Additionally, the noise level stays roughly 5 dB lower than comparable engines, which improves onboard comfort. The X6170 series also meets IMO Tier II and China Stage I emission requirements, allowing vessels to operate while staying compliant with international and regional regulations.

Practical and Easy to Use

The exclusive Voyage-Mate monitoring system tracks speed, water temperature, oil temperature, oil pressure, and other parameters in real time. It triggers automatic alarms and shutdown when values exceed limits. Furthermore, the added rough-sea mode helps prevent unexpected stoppage during critical sea conditions, giving operators greater confidence on long journeys.

Ideal for Multiple Marine Applications

Because of its strong power output, reliable core structure, and broad working range, the Weichai X6170 258–601 kW Marine Engine fits fishing vessels, transport ships, working boats, and various coastal applications. It delivers stable performance, long service life, and low operating costs—making it a practical choice for shipowners seeking both value and durability.
