00:002-stroke engines have been used in a wide variety of applications, from motorcycles
00:05to lawnmowers, due to their simple design and high power-to-weight ratio.
00:10Unlike a 4-stroke engine, which requires 4 piston strokes to complete one power cycle,
00:16the 2-stroke engine achieves the same process in just 2 piston strokes, delivering more
00:21power in less time.
00:23In this video, you'll learn how a 2-stroke engine works.
00:27Before we get into the process, let's take a look at the key components that make up
00:31a 2-stroke engine.
00:33At the heart of it all is the piston, moving up and down inside the cylinder.
00:39Unlike in a 4-stroke engine, where intake and exhaust valves are used to manage the
00:43flow of gases, here we have the exhaust port, the inlet port, and the transfer port.
00:51The piston itself covers and uncovers these ports at specific points during its movement,
00:57controlling the intake and exhaust process.
01:00The crankcase, located below the cylinder, plays a crucial role too.
01:05It houses the crankshaft and acts as a pump for the fuel-air mixture.
01:10The 2-stroke engine operates with just two distinct phases, the power stroke and the
01:15compression stroke.
01:16Let's begin with the power stroke.
01:18The cycle starts when the piston is at its highest point.
01:22At this point, the air-fuel mixture inside the combustion chamber is fully compressed.
01:28The spark plug ignites the mixture, creating a rapid combustion reaction.
01:33This explosion generates high-pressure gases, forcing the piston downward.
01:38As the piston moves down, it first uncovers the exhaust port.
01:43This allows the burnt gases from the combustion process to escape from the cylinder through
01:47the exhaust port.
01:49The timely removal of these gases is critical, as it makes room for the incoming fresh fuel-air
01:54mixture.
01:56The piston keeps on moving down, squeezing the fuel-air mixture in the crankcase.
02:01As the piston descends further, it reaches a point where it uncovers the transfer port.
02:07At this moment, the fresh air-fuel mixture is released from the crankcase and fills the
02:11cylinder above it, pushing out the remaining burnt gases through the exhaust port.
02:17Moving on to the compression stroke.
02:19As the piston moves up, it clears the intake port, drawing in the fresh air-fuel mixture
02:24from the carburetor that fills the crankcase.
02:27As the piston ascends further up, it closes off exhaust, transfer, and inlet ports sealing
02:34the combustion chamber.
02:36With all the ports closed, the fresh air-fuel mixture that entered the cylinder during the
02:40first stroke is now trapped.
02:42As the piston rises, the mixture becomes compressed, increasing the pressure and temperature
02:48inside the combustion chamber.
02:50This sets the stage for ignition by the spark plug, starting the cycle all over again.
02:56One of the key distinguishing features of a two-stroke engine is its use of the crankcase
03:01as a pump for the fresh-fuel-air mixture.
03:04While in a four-stroke engine, a separate stroke is dedicated to the intake of the air-fuel
03:09mixture, a two-stroke engine accomplishes this during the downward movement of the piston.
03:15Two-stroke engines have a unique approach to lubrication.
03:18Instead of relying on a separate oil circulation system, most two-stroke engines mix oil with
03:24the fuel, a process known as petrol lubrication.
03:28This oil helps lubricate the moving parts.
03:30However, the lubricating oil can sometimes find its way into the cylinder, where it burns,
03:36eliminating the blue smoke commonly seen in two-stroke engines.
03:40Two-stroke engines are simpler, lighter, and offer more power strokes per cycle compared
03:45to four-stroke engines.
03:46However, they tend to be less fuel-efficient, and their exhaust gases contain unburned fuel,
03:52making them more polluting and expensive to run in the long term.
03:56Despite their drawbacks, two-stroke engines continue to power many machines today due
04:01to their simplicity in power output.
04:03Understanding their operation gives us insight into how engines shape the technology around us.
