Four GE turbofan engines generate 56,000 pounds of thrust each. This adds to 224,000 pounds of thrust altogether.
There are two types of turbofan engines- high bypass and low bypass engines. About 80 percent of the total engine thrust from a high bypass turbofan engine is produced by the bypass of air around the core. These types of engines generally have a large fan in the front to pull in large volumes of air to produce such a powerful jet stream out the back. The front fan is driven by the compression, combustion, and expulsion of the hot gases out the back of the core. About 20 percent of the air pulled in from the front fan is used to drive the core. High bypass turbofan engines are used on almost all commercial jet aircraft because they burn less fuel. A low bypass engine is exactly the opposite. The core is used to drive a smaller fan in the front which only about 20 percent of the total volume of air pulled in is bypassed. The remaining 80 percent of the air being drawn into the engines core is compressed, combusted, and the hot gasses expelled out the back to produce the necessary thrust to propel a jet forward. Low bypass turbofan engines are found on jets that require supersonic speeds. These engines are incredibly powerful but at the cost of a high fuel burn rate.

An aircraft uses a turbofan engine to reach takeoff and cruising speed. Look up TURBOFAN on Google for more info!
High Bypass turbofan engines use pneumatics (air) for starting the engines.

No. There are not "spark plugs" on turbofan engines. There are ignitors, which help to ignite the fuel during start, but unlike spark plugs, ignitors do not run constantly.

Turbofan thrust refers to the propulsion generated by a turbofan engine, which is commonly used in commercial and military aircraft. This type of engine combines a gas turbine core with a large fan at the front, producing thrust by accelerating a substantial mass of air through the engine. The thrust is generated both from the high-speed exhaust gases and the bypass air that is moved by the fan, making turbofan engines efficient for long-haul flights. The thrust produced can be adjusted by varying the engine's power settings, allowing for effective control during different phases of flight.
