TWO STROKE ENGINES

These engines complete a power cycle with two strokes (up and down movements) of the piston during one power cycle. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving
parts than four-stroke engines.
Advantages
  • Simple mechanism.
  • Easy to start.
  • It gives one power stroke per revolution of the crankshaft. High power to weight ratio and
  • significant power boost.
  • It has no valves, so complicated valve actuating mechanism not required.
  • It is light weight, 30% lighter than the 4-stroke engine.
  • It has few moving parts, so compact and simple construction.
  • Low maintenance cost.

    Two-stroke petrol engines are preferred when mechanical simplicity, light weight, and high power-to-weight ratio are design priorities. By mixing oil with fuel, they can operate in any orientation as the oil reservoir does not depend on gravity.
