Many people think that those heavy six-wheeled, eight-wheeled, and large-sized heavy-duty trucks are already giants, coupled with the huge sound of its operation, and its large displacement. This is simply a steel giant. However, these monsters are simply ants in front of what they see next. With the ever-increasing size of ships, especially container ships, these can be regarded as true mega-mass, with more than a dozen or hundreds of thousands of tons of displacement. With such huge giants, to drive it forward, the components of its internal equipment must also be huge, such as engines. In order to promote huge ships, the power naturally cannot be too low, so large-capacity and large-scale marine diesel engines have emerged. A Wärtsilä company specializing in marine diesel engines in Finland introduced a 14-cylinder RT-flex96C diesel engine. It is the world's most powerful low-speed marine diesel engine, improved by the RTA96C diesel engine, but it is more excellent than it. The machine is a 14-cylinder RT-flex96C marine diesel engine with a continuous output of maximum power of 80080 kilowatts and a rotational speed of 102 rpm. It is 27.3 meters long and 13.5 meters high. It weighs 2,300 tons and has a displacement of 25,480 liters. It has a power of 108,920 horsepower and a maximum speed of 102 rpm. Applicable to a new generation of large container ships. The well-established RT-flex common rail technology has been adopted to improve the rigidity and reduce the structural stress. It has good reliability, safety and durability, and has the advantage of more convenient maintenance than similar models. This diesel engine not only has a large amount of power, but its efficiency is also much higher than that of an ordinary automobile engine. It has achieved a staggering 50% thermal efficiency through a series of technologies. We must know that even more advanced The gas turbine engine, which is only a little over 60% efficient, burns heavy oil and consumes 6,400 liters per hour. If you supply this amount of fuel to the car, you can circle the earth two times. The 14-cylinder RT-flex96C diesel engine is an economical propulsion system tailored for large, high-speed container carriers. It is suitable for a speed of 25 knots (1 knot equals 1 knot per hour, ie 1.852 km/h). The 3000 to 10,000 TEU or larger container ship, the first RT-flex 96C was adopted by the Emma Marsk container ship. ◠Postscript: One engine is 2300 tons, 27.3 meters long, 13.5 meters wide, which is already larger than most of the trucks, except for the mine trucks used in open-pit mines. Is this big guy expensive? In actual fact, its oversized parts use ordinary common steel materials, and only the key parts are made of special materials. Compared with gas turbines whose whole body is a special material more expensive than gold, that can be much cheaper. Due to its huge size and low rotational speed, its range of use is relatively single. In addition to large ships, there is no Other place where it will be used.
