Basic engine operation can be divided into four stages. these stages (listed in the proper order) are

The answer would be: Intake, Compression, Power, and Exhaust.

Intake: also known as induction or suction.
Compression: starts at the end of the suction stroke, and ends at T.D.C. 
Power: also known as combustion. This is the start of the second revolution of the four stroke cycle.
Exhaust: also known as outlet. In here, the piston once again returns from B.D.C. to T.D.C. while the exhaust valve is open. This action eliminates the spent air-fuel mixture through the exhaust valve.

Answer dispose of it in accordance with federal , state, and local requirements;

To solve this integral, what you can do is split it up as follows: (1) ∫40(x2−4)dx=∫40(x2)dx−∫40(4)dx. to integrate  4  as an  indefinite integral, a good rule of thumb is  by  an equation below  for  polynomials; . (2) ∫xa=xa+1a+1+c , where a is any number. c denotes some constant that is crucial when doing
