WEIFANG ZH4102ZC Marine Diesel Engine

★ Introduction of Marine Main Engines:

1. Structural Design: Inline four-cylinder engine with frame-type main bearings, resulting in high engine rigidity, 

low vibration, and low noise; one cylinder, one cover for convenient maintenance; water-jacketed exhaust pipe 

reduces engine compartment temperature.

2. Cooling System: Dual-cycle cooling system with both freshwater and seawater heat exchange; freshwater cools

 the engine, and seawater cools the freshwater, preventing direct corrosion of critical components by seawater 

and extending engine life.

3. Control System: Standard intelligent monitoring system for real-time monitoring of engine speed, water temperature, 

oil pressure, etc., with automatic alarm/shutdown when exceeding limits; remote control is optional.

4. Adaptability: Compatible with outboard motors, gearboxes, generators, or anchor winches; external power output 

interface reserved; high accessory integration; flexible engine compartment layout.

★ Core Advantages:

1. High Reliability and Durability: Key components are made from premium materials; the frame-type main bearing

 is impact and vibration resistant; dual-cycle cooling and water-jacket exhaust design significantly extend the overall

 lifespan, suitable for long-term continuous operation.

2. Economical and Efficient: Direct injection + turbocharging technology improves combustion efficiency, resulting 

in low fuel consumption and controllable operating costs; low maintenance costs, interchangeable wear parts, and 

convenient procurement and replacement.

3. Safe and Controllable: Intelligent monitoring and automatic protection systems reduce operational risks; electric

 start, remote control, and other features facilitate easy operation and are suitable for marine navigation habits.

4. Strong Adaptability: Power output covers the needs of small and medium-sized vessels; can be flexibly integrated 

with various marine equipment; complete accessories facilitate quick installation and integration; comprehensive 

after-sales network.

★ Engines Applicable Scenarios:

1. Main engines for small inland/coastal fishing boats, aquaculture vessels, transport boats, and workboats.

2. Auxiliary engines for ships (such as generators and anchor handlers) or power systems for small engineering vessels.

3. Preferred choice for owners of small and medium-sized boats who are cost-sensitive and prioritize reliability and ease of maintenance.
