Sourcing Guide: Why China Diesel Generator Suppliers Recommend Yuchai as a Small Marine Diesel Generator Alternative

Fitting out a gill netter? Or maybe refitting a ferry? You know the engine room is valuable space. Every meter matters. Big engines like Weichai or Cummins rule the heavy freighter market. But for smaller boats, they are often too much. Too big. Too heavy. That is why expert China diesel generator suppliers suggest a different name: Yuchai.
As a small marine diesel generator, Yuchai is now a top pick. Fleet owners like it because it gives steady power but takes up less room. Saving space is part of it. But it is also about getting a strong machine into a spot where other brands just won’t fit.
The “Compact” Advantage: Why Size Matters
Doing a refit project? Then you know the pain. Trying to squeeze a new genset into an old room is hard. With standard engines, you might have to cut the deck. Or you might have to move all the pipes. A compact marine diesel generator fixes this before it becomes a problem.
Look at the Yuchai 30kW model (CCFJ30Y). The size is just 1770×750×1200 mm. That is much smaller than other units with the same power. This small shape gives you more room to fix things later. Also, there is less weight to slow down the boat. For generator set manufacturers like Uleengen, Yuchai is the right mix. You get good power without the bulk.
Weichai vs. Yuchai: A Quick Comparison
Many buyers wait. They know the Weichai name better. But bigger isn’t always right. The table below shows why you might pick one over the other. It depends on your boat.

Power Range |
Focuses on 300kW – 2000kW+ |
Strongest in 10kW – 400kW range |
Do you need heavy power over 500kW for a container ship? Then checking the Weichai Series marine generator options is smart. But for 50kW to 400kW? A small marine diesel generator from Yuchai often pays for itself faster.

Technical Specifications: Choosing Your Power
Uleengen sells Yuchai marine generators from 10kW up to 1000kW. These are tough 4-stroke engines. They use a sea water heat exchanger for cooling. This helps them handle the heat in a closed room. Also, these sets have a CCS certificate (China Classification Society). This means they meet safety rules at sea.
See the chart below for popular models. Look at the weight and size. These numbers show why Yuchai leads the compact marine diesel generator market.

Real-World Applications for Commercial Vessels
Yuchai marine generators work hard in many spots. They can be backup power for big ships. But usually, they are the main heart for small or medium commercial boats.
- Commercial Fishing:Used often on gill netters, seiners, and trawlers. Here, saving fuel means making more money.
- Transport & Logistics:Steady power for ferries, tugboats, and crew boats. These boats must stay on time.
- Specialized Vessels:Trusted on fire boats and yachts. They must start every time.
These generator sets do more than help move the boat. They handle many electrical jobs. They run the AC to keep the crew cool. They power kitchen tools like freezers and stoves. They also run safety tools like radar and floodlights. Maybe you are running a water maker. Or charging batteries. Yuchai gives steady power to keep electronics safe.

Customization: Alternators and Frequency
