Product Description

High Performance Yc6K Series Marine Diesel Engines for Boats and Ships
The YC4A series diesel engine is a product developed by Yuchai using German technology. The use of BOSCH high-pressure common rail fuel injection system, high-performance combustion chamber and intake vortex makes the engine fuel economy far better than the domestic products with the same power file. Suitable for 30-100kW marine generator set.

Application:fishing-boat/cargo-ship
Power Coverage:55~220HP


Feature:

High reliability

  • The airframe and cylinder head are made of alloy cast iron, with a high
of reinforcement, an overall crankshaft, and an overhaul period of more than 10,000 hours after deep reliability.

Energy conservation

  • Through the three-dimensional combustion CFD technology in the cylinder, the combustion emissions are optimized and the combustion is more complete.
  •   Using high-pressure common rail system, high-performance combustion chamber and intake air vortex, the fuel consumption index is far better than the domestic products with the same power file.
  • Using Yuchai's proprietary piston ring sealing technology, the lubricating oil consumption is more than 50% lower than that of domestic products with the same Power life.

Environmental protection

  • The full electronic control technology meets the emission standards of China and IMO II of the ship.

Safe and comfortable                                                                       

  • Equipped with digital intelligent side and remote monitoring instruments, real-time monitoring and protection of engine operation.
  • The use of integral cast iron fresh water cooling water jacket exhaust pope makes the cabin temperature lower and safe to use.

Good serviceability

The parts common rate of the 4A car and General purpose machine model is as high as 80%, and the versatility of the parts is high;
Dual line filtration and double diesel filtration are adopted to achieve non-stop maintenance.
