The 10 most powerful engines in the world can consume 300,000 liters a day, and Bugatti W16 is on the list.

1. Sulzer-—flex96C marine diesel engine

Sulzer -flex96C marine engine is a two-speed and low-speed diesel engine manufactured by Finnish company. It is designed for large-scale use of heavy fuel.

The largest 14-cylinder version is 13.5 meters high, 26.59 meters long and weighs 2,300 tons, with a power output of 80080 kW(107390 hp). The 14-cylinder version was first put into commercial service on EmmaM?rsk in September 2006.

This diesel engine has a displacement of 1,810 liters per cylinder and a single weight of 5.5 tons.

2、W16

Is a very powerful power system, its development began in 1997, led by Ferdinand Karl Pich, chairman of the management committee.

In the development process, it has undergone many evolutions and finally became a four-turbocharged 8.0-liter 16-cylinder engine.

This engine was tested for the first time in 2001, reaching the output target of 987 hp (about 736kW) at the beginning of design. Because the engine has huge power, Bugatti has developed new engine testing methods, including engine test bench.

Bugatti upgraded the W16 engine in 2010, adding a larger turbocharger and other modules, which increased its output power to 1183 hp. Then Bugatti introduced various new technologies to improve the performance of W16. Now this W16 can output 1578 hp, and it has 3,712 independent components. It takes two skilled technicians six days to assemble such a W16 engine.

Because the manufacturing process of Bugatti’s engine is extremely complicated, it takes at least half a month to complete each car engine.

3、—115B

GE90-115B engine was developed by Youwei and B777-200LR aircraft, and it is the engine with the highest thrust in the world. Its thrust reaches 511kN(11500lbf), and it has the structural characteristics of high biaxial.

It has two rotors, a low-pressure rotor (N1) and a high-pressure rotor (N2). The maximum rotation speed of N1 is 2602rpm, and the maximum rotation speed of N2 is 11292rpm. The engine also has a primary core airflow and a secondary bypass airflow, and the bypass ratio is 9:1, which means that the external bypass airflow is 9 times that of the core engine.

The core engine airflow passes through the combustion section and the combustion section, and the burned part will get fuel from the fuel nozzle. The age, condition and bleed air configuration of each engine will lead to different exhaust temperature (EGT) of the engine. It is normal that the exhaust temperature is different when idling and running at low power. Generally, the ground start EGT of the engine will be lower than 750°C. If the EGT exceeds 750°C, the automatic start function of the engine will stop. If there is something wrong with the air bleed system of the aircraft, it will make the EGT of the engine start higher and take longer to start the engine.

The maximum temperature limit of the engine is no more than 5 minutes at 1090°C when taking off (more than 10 minutes may cause the engine to shut down unexpectedly), no more than 30 seconds at 1095°C, and there is no time limit for running at 1050 C.

4. HTS propulsion motor

HTS propulsion motor is the application of HTS materials in ship propulsion system. In 2003, American Superconductor Company cooperated with, built a 5MW/230rpm HTS motor (model) for ship propulsion, and successfully carried out a no-load factory test.

This is an intermediate demonstration link to demonstrate the technical process for building a 25MW/120rpm HTS full-size marine propulsion motor. This marks an important breakthrough in the application of HTS technology in the propulsion system of aquatic ships.

HTS propulsion motor has the advantages of high efficiency, high thrust, low noise and low pollution. High temperature superconducting materials work at low temperature, so they can use more efficient and sustainable energy sources, such as or. At the same time, the HTS propulsion motor can accelerate faster, which can provide higher thrust and longer duration.

5. Saturn 5 engine

Saturn 5 engine is a kind of engine, which is used in two space programs, Skylab and Skylab. It is one of the largest at present, with a height of about 18 meters, a weight of about 81,600 and a maximum thrust of 33,400 kilonewtons.

Saturn 5 rocket engine uses liquid oxygen and fuel. It consists of five engines and is installed at the bottom of Saturn 5 rocket, which enables the rocket to generate enough thrust to send astronauts to the moon. The nozzle adopts a long and narrow conical design, which makes the speed of the ejected gas at the nozzle mouth extremely high and produces greater thrust.

In addition, its components, such as fuel and oxygen, can inject liquid fuel and oxygen into the nozzle and make it burn to generate high temperature and high pressure gas, thus generating greater thrust.

Saturn 5 rocket engine also has efficient combustion chamber and turbopump, which can inject liquid fuel and oxygen into the nozzle to make it burn to produce high temperature and high pressure gas, thus generating greater thrust.

6. CM884WS—150 engine

This huge eight-cylinder two-stroke diesel engine was installed in the power station. From 1932 to 1962, it was called the largest in the world.

Its scale is incredible: it is about 25 meters long, 12.5 meters high and weighs 1400 tons. The 730mm thick self weighs 140 tons, and the whole process needs 40 tons of lubricating oil. Although there is no displacement figure available, the power figure is: it produced 22500bhp.

7. GE1750MW Alabert

GE1750MW Alabert engine is an efficient and powerful engine developed by (ge) and used in Alabert project.

The engine adopts advanced technology and design, has high power generation efficiency and reliability, and can run stably in various harsh environments. GE1750MW Alabert engine adopts Direct-Drive generator, which can directly convert the power into electric energy, avoiding the problem of energy conversion through intermediate links such as gearbox in traditional wind power generation system, thus reducing mechanical loss and failure rate.

In addition, the engine also adopts the Doubly Fed Induction generator technology, which can realize the independent control of the rotor side and stator side, thus achieving the optimal power generation efficiency under various wind speed conditions.

At the same time, GE1750MW Alabert engine is equipped with advanced control system and health monitoring system, which can monitor the running state of the engine in real time and give early warning of faults, thus ensuring the safety and reliability of the whole wind power generation system.
