 Features

1. The main structure comes from of Landking Euro III high-pressure common rail diesel engine


2. Enhanced engine body, crankcase, cylinder head, crankshaft, and connecting rod.


3. The main components are subjected to finite element analysis and simulation calculations, resulting in a significant increase     in operational reliability and service life.


4. The turbocharger position can be subject to customer requirements.


5. The intercooler and heat exchanger are reasonably arranged at both ends of the diesel engine.


6. Reasonable matching between intake & exhaust and fuel system, with a minimum fuel consumption of 192g/kW·h. PZ8500     in-line flange pump for fully atomized fuel and stronger performance.


7. Four-valve structure with sufficient intake air for combustion and reduced fuel consumption.


8. Broadened engine operating range with good economy under various working conditions.


9. Enhanced engine structure with support and low-noise gear chamber.


10. The special oil sump makes the diesel engine noise much less.


11. Advanced emission indicators with a full load range of less than 1.0Rb.

The WP12C series marine diesel engine is a variant of the WP12 Blue Engine series diesel engine. The design of the diesel engine complies with the relevant national standards and ship regulations. It has the characteristics of reliable use, excellent economic and technical indicators, low emission, quick start, simple operation and convenient maintenance. It is the ideal power for small and medium-sized ships.
