WEIFANG ZH4102ZC Marine Diesel Engine

★ Introduction of Marine Main Engines:

Marine main engines work at full load most of the time, and sometimes operate at variable load. Ships often sail in turbulence, so marine diesel engines should be able to work reliably under conditions of 15°~25° longitudinal inclination and 15°~35° transverse inclination. Most ships use supercharged diesel engines (see internal combustion engine supercharging), and low-power non-supercharged diesel engines are only used on small boats. Most low-speed diesel engines are two-stroke engines, most medium-speed diesel engines are four-stroke engines, and high-speed diesel engines have both. The scavenging forms of marine two-stroke diesel engines include reflux scavenging, port-valve direct current scavenging, and opposed piston port scavenging. High-power medium and low-speed diesel engines widely use heavy oil as fuel, and high-speed diesel engines still mostly use light diesel.

★ Features and Advantages of Marine Main Engines:

1. Unique frame-type main bearing structure, high body rigidity, small vibration amplitude, and low noise decibels.

2. One cylinder and one cover, convenient vehicle maintenance and processing, reducing maintenance consumption costs.

3. Major parts are purchased from all over the world, achieving high configuration of the engine.

4. The diesel engine accessories are fully installed, and the air cooler, seawater heat exchanger, etc. are installed on the diesel engine, which is convenient for the layout of the engine room.

5. The diesel engine cooling system adopts internal and external double-circulation water cooling. The internal circulation uses fresh water to cool the diesel engine, and the external circulation uses seawater to cool the fresh water through the seawater heat exchanger, which increases the service life of the diesel engine.

6. Perfect protection and control system, using diesel engine function monitor, can automatically measure and display the speed, water temperature, oil temperature and pressure of the diesel engine, when the diesel engine parameters exceed the limit, it can automatically alarm and shut down, and can be equipped with a remote controller.

7. Excellent design, using water jacket exhaust pipe to keep the cabin temperature low.

8. Good matching adaptability, WD615C, WD618C series diesel engine flywheel, flywheel housing, diesel engine monitoring instrument, water jacket exhaust pipe, seawater pump and other parts are common. The diesel engine installation dimensions, flywheel and flywheel housing dimensions are also the same, which facilitates matching and maintenance.

9. The crankshaft front end pulley is reserved with a pulley groove and a connecting flange for users to use with external power output devices.
