In the field of marine engines, Weichai's products have a high reputation in the industry. Today, I will introduce a V-type 12-cylinder marine engine produced by Weichai Baudouin to see how different this behemoth is.
The first impression of Baudouin's V-type 12-cylinder engine is that it is large and very large, more than an order of magnitude larger than the volume of a car engine. It is a product of Weichai's Baudouin company, model 12M26.3, the cylinder bore and piston stroke are both 150 mm, and the displacement is 31.8 liters. With a rated power of 1214kW, it can output an amazing torque of 6900Nm at 1700rpm. Mainly used for the main or auxiliary engine of coastal fishing boats, transport ships, engineering ships, high-speed boats, yachts and other ships.
This Big Mac engine uses two turbochargers, which are arranged on both sides of the cylinder block, and together with the accessories such as the intake port and the cooling water pipe, they form a perfect symmetrical structure. This design makes the engine full of mechanical sense, maybe this is the charm of the V-type engine.
In order to ensure the clean oil, provide reliable lubrication and cooling to the engine, and prolong the working and maintenance time and service life of the engine, this engine with 12 cylinders is equipped with a centrifugal oil filter on each side of the cylinder block to filter out finer impurities.
This type of engine is equipped with two sets of redundant electronically controlled high-pressure common rail systems. In normal work, the two systems supply fuel to the cylinders on both sides respectively. When one system fails, the other system will take over the failure system. Continue to maintain the engine work, this design which is both independent and complementary to each other greatly increases the reliability of the fuel system, enabling the engine to stably create value for customers.
Since it is a marine engine, it is designed with full consideration for the convenience of maintenance. The valve cover, centrifugal oil filter, oil filter, fuel filter and fuel pump are disassembled and maintained convenient. The huge size and displacement inevitably require a huge supply of fuel and oil. For this reason, this engine is equipped with six huge filters. The three installed side by side above are the fuel filters, and the lower one is the oil filter installed in an inverted triangle. It is worth mentioning that these filters can be replaced while the engine is running, and no shutdown is required. This design fully satisfies the sustainability and safety of the ship's power requirements.
Through these top designs, we can see the comprehensive strength of Weichai. With its profound industrial heritage and technical reserves, Weichai leads the industry to the high end.
