Applications, Pros and Cons of Two-Stroke Engines

Two-stroke engines tend not to be common with the four-stroke engines, because it is designed to power small devices. Unlike the four-stroke that powers almost every car and truck on the road today. It is important to know what differentiates these engines, which have been clearly examined in another article.

Applications

Gasoline and diesel engines have great effectiveness on a two-stroke, making their applications so broad. The following are the applications of two-stroke engines in different areas.

Spark ignition known as the gasoline version of a two-stroke engine is mainly effective in portable and lightweight devices. These applications include Chainsaws and motorcycles. But, when size and weight are to be considered the cycle’s probably for high thermodynamic efficiency makes diesel compression ignition engines to be used on large and heavy weights applications, such as marine propulsion, railway locomotives and electricity generation.

  • Lawn and garden equipment
  • Dirt bikes
  • Mopeds
  • Jet skis
  • Small outboard motors
  • Radio-controlled model planes
  • Chain saws and jet skies

Advantages and disadvantages of two-stroke engines

Pros

The following are the advantages of two-stroke engines:

  1. Two-stroke engines do not have valves,  making them much easier to construct and lowers their weight
  2. two-stroke engines have a lower output in horsepower
  3. It fires once in every revolution while four strokes every other revolution,
  4. Two-stroke engines can work in any position, due to the oil flow is not a problem with any valves to worry about.

Cons

The following are the disadvantages of two-stroke engines in both gasoline and diesel engines:

  1. The two-stroke engine has no lubrication system, making the engine parts wear out faster.
  2. Two-stroke consume much oil; it would burn a gallon every 1000 miles if it were in a car
  3. It uses more fuel
  4. Two-stroke engines produce a lot of pollution
  5. Fuel can easily escape from the chamber through the exhaust port.
  6. Two-stroke engines are always dirty, due to the escaped air/fuel around the outboard.
