question 3 of 10 which of the following sequences describes how a four - stroke engine cycle powers the engine? a. expansion, air and fuel intake, compression and ignition, extinguishment b. air and fuel intake, compression and ignition, combustion and expansion, exhaust c. contraction, compression and ignition, air and fuel intake, exhaust d. hydrogen and fuel intake, expansion, compression and ignition, exhaust

Answer

Brief Explanations:

In a four - stroke engine cycle, first, air and fuel are taken into the cylinder (intake stroke). Then, the mixture is compressed and ignited (compression stroke). After that, the combustion of the fuel - air mixture causes an expansion (power stroke), and finally, the exhaust gases are pushed out (exhaust stroke).

Answer:

B. Air and fuel intake, compression and ignition, combustion and expansion, exhaust
