Engineers need to be able to solve problems... If there is no problems, there are no need for engineers, therefore no jobs for engineers.
no, but you need engines to control the airship (AKA blimp)
jet engines require air, compression, and combustion to make it work
The engines on TO20 Ferguson tractor are interchangeable on the engines of the TE20 Ferguson tractor. They need very little moderation.
Zero.
There are so many you need a car make and model to tell you what engines are for that? all car engines are of the internal combustion type, fueled by gasoline.
Diesel engines need more cranking power than what one battery provides.Diesel engines need more cranking power than what one battery provides.
This is a very vague question. Almost all engines have different firing orders. You need to ask for the firing order for what model engine you have or need.
2 wings, to determine which engine was used need to know what biplane
No, they are not powered (they need chains or launchers to get up the first hill) and therefore, they do not have engines.
it could be for the spark plug, petrol engines dont need glow plugs, diesel engines do
Yes ... but not with chemical engines - we need ion rockets - or perhaps nuclear engines.
It isn't a matter of why they need it! Some planes are just designed with jet engines! Jet engines take a small amount of air and push it out fast whereas props take a large amount of air and push it back slower! Some planes just have jet engines!
