Product Description


The CAMC high-power diesel engine adopts an inline six cylinder, four valve, four stroke design, specially developed for optimizing ship power systems. The core structure integrates a top mounted camshaft, an integral cylinder head, and a symmetrical gantry cylinder block, and the layout of the rear gear chamber improves transmission efficiency by 15%. Innovative application of double-layer water jacket cooling technology improves heat dissipation performance by 30% compared to traditional designs. Combined with deep skirt cavity structure and symmetrical cylinder block, it achieves uniform stress distribution and overall high strength.

The piston system balances strength and thermal management requirements by optimizing internal cooling oil circuits and applying high-temperature refractory materials. The top mounted camshaft design simplifies the transmission chain and outputs a maximum power of 353kW at 1800r/min, with a 12% increase in fuel efficiency. Suitable for scenarios such as inland ships and offshore operation platforms, it has become the preferred solution in the field of ship power with reliability and high efficiency.

Product Advantages


Excellent power performance

Adopting an inline six cylinder four valve design, with a maximum power of 353kW (1800r/min), coupled with optimized combustion system, the power output is 15% higher than that of the same class, meeting the continuous high load operation requirements of ships.

 

Military grade reliability

Innovative symmetrical gantry cylinder block+deep skirt chamber structure, key components have passed 100000 hours of bench testing, with an average time between failures (MTBF) of 8000 hours, suitable for extreme working conditions.

 

Intelligent thermal management system

The patented double-layer water jacket cooling technology, combined with the internal oil circuit of the piston, improves the heat dissipation efficiency by 30%, ensuring full power output at an ambient temperature of 45 .

Customer Reviews


Technical Director of German Shipbuilding Manufacturer

Our CAMC engine has accumulated 15000 hours of operation without major repairs on the Baltic cargo ship. The stable output of 353kW perfectly matches our propulsion system, and the double-layer water jacket cooling technology allows the engine to quickly heat up to optimal operating conditions even in extremely cold environments of -25 . The most satisfying aspect is its fuel economy, which saves 12% of operating costs compared to similar European products.

 

Operations Manager of Brazilian Shipping Company

In the high temperature and high humidity environment of the Amazon River, this batch of engines demonstrated astonishing reliability. With a speed of 1800r/min and an optimized transmission system, our inland transportation efficiency increased by 20%. The Portuguese technical support and 48 hour spare parts response service provided by Chinese engineers greatly reduced our downtime losses.
