Engine Operation:

The engine operation occurs in four main stages, as its function of any four-stroke engine requires the crankshaft to rotate twice in the machine covering about 720° degree of rotation while on its position.

While, the four main stages for the engine to operate are as follow:

renewable resources- resources that can be replenished (such as trees)

nonrenewable resources- resources that are gone once they are used (such as fossil fuels)

producer-person who makes goods or provides services

consumer- person whose wants are satisfied by using goods and services

allocate- distribute

choice- option
