Why are 2 stroke engines banned?

Answer: Two-strokes left the market

because they could not meet steadily-tightening EPA standards for vehicle exhaust emissions

. … A four-stroke engine has a separate piston stroke for each of the four functions necessary to a spark-ignition engine: intake, compression, power, and exhaust.

Why do 4 strokes have more torque?

This is due to the fact that

fuel is consumed once every 4 strokes

. Four-stroke engines are heavier; they weigh upwards of 50% more than a comparable 2stroke engine. Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM.

Why are 2 strokes so loud?

Two-stroke engines do not have intake and exhaust valves to regulate the flow of fresh air into, and exhaust gas out of the combustion chamber. … As a result, there are

two sound waves leaving the exhaust on every stroke

(or combustion cycle) resulting in a higher frequency or pitch, and therefore louder noise.
