Jet engine power ratings are generally in terms of thrust, not torque. The 747 has undergone several engine redesigns. The Pratt & Whitney JT9D engine series varies from a maximum thrust of 46,300 to 50,000 lbf.

The engine head torque specification for a Briggs & Stratton engine can vary depending on the specific model and engine type. However, a common torque range is typically around 20-30 ft-lbs for most small engines. It's essential to consult the owner's manual or service manual for the specific engine model to ensure accurate torque settings. Proper torque is crucial for preventing damage and ensuring optimal engine performance.


What is meant by engine load and is it the same as engine torque?

engine load is how muchdemand is placed on the engine for power such as playing the music, rolling down the windows and running the A/C system and using the wipers while starting the vehicle for example is all load it can be one of these or all of these does not matter each and everything you do is a load on the engine... Torque is how much power the engine puts out to actually turn the gears to move the vehicle or how much force the engine produces to apply to the gear set to turn the wheels... some gear sets such as 4x4 gear sets increase engine torque considerably when used in low or granny gear or crawl modes in almost all cases the bigger your engine the more baseline torque you can produce which will be transferred to your gear sets via the transmission.
