Most hobby rockets engines are constructed of wood, plastic or paper, many different kinds of accelerates can be used.
Please see related links below. There is gunpowder in the engine
Buy and assemble an Estes model rocket kit. Use only commercial premade engines, never even consider making a engine yourself!
Model rockets can use anything from 1/4A to G engines.Amateur rockets can use up to N engines.Professional rockets have no limit.Each successive engine letter has twice the power of the previous. Assuming Professional rockets start with O engines, the smallest Professional rocket engine has 256 times the power of the largest Model rocket engine. Most will of course be much larger.
The normal use is propelling a rocket.

Because there is no friction in space to slow the rocket down. Once the rocket is at its cruising speed, the engine can be switched off. Of course, that means that you have to use a different engine (pointing forwards) to slow down and stop the rocket since friction won't do it for you.

The only use I know of for this term is in model rocketry. A model rocket's engine is made up of several layers of propellant. After the propellant, the primary layer that shoots the model rocket up, has burned out, a layer called the "delay charge" burns. This layer doesn't push the rocket, it just puts out smoke so you can see where the rocket is and creates a delay before the last layer called the "ejection charge" which pushes out the parachutes or whatever method method is used to recover the rocket. I'm adding a link to a wikipedia page on model rocketry. If there is another meaning, maybe someone who knows will come by.
depends on your model... if you have a turbo you will want to use 92-93 so you dont hurt the engine... if it is a reg model (ls, lt) save your money use 87
For the Kohler engine model CV16S with type number PS-43512, the recommended oil filter is the Kohler 12 050 01-S. It's essential to use the correct filter to ensure optimal engine performance and longevity. Always verify compatibility with your specific engine model before purchasing.
