2 stroke engine vs 4 stroke engine What is made of piston and why

Question

Accepted Answer

2 stroke engines have simpler design but less efficient than 4 stroke engines. Pistons are made of aluminum alloy for light weight.

2 stroke engines have only two strokes (intake/compression and power/exhaust) while 4 stroke engines have four strokes (intake, compression, power, and exhaust).
2 stroke engines have simpler design and are lighter but less efficient than 4 stroke engines.
Pistons are made of aluminum alloy for light weight and good heat dissipation.
Pistons are a crucial component of internal combustion engines, converting the energy from the fuel into mechanical energy.
Pistons move up and down inside the cylinder, compressing the fuel mixture and transferring the energy to the crankshaft.
