Differences 2-stroke engine and 4 stroke engine.

Good night all steemit friends. Hopefully given health always. Immediately this time I want to explain a little about the difference of 2-stroke engine (step) with a 4 stroke engine. Maybe many of us who do not know the difference from both machines.

Differences 2 stroke engine and 4 stroke that is in the form of the engine, then ignition is given, fuel efficiency, and power generatef.

MACHINE 2 STROKE
This 2-stroke machine means, to get 1x effort, it takes 1x crankshaft rotation and 2x piston movement (down & up). In the 2-stroke engine, the engine construction is quite simple, where there are pistons, crankcase, inlet valves in the form of membranes, rinse channels, and exhaust channels. As seen in the picture below, about this is the innards engine 2 stroke.

Step suction & compression together.

Ways of working:

1. Step suction and compression step
   The piston moves from the bottom dead point, to the top dead point. The open membrane and fuel mixture (green color) enter the crankcase of the carburetor through the inlet. While the fuel mixture at the top of the piston surface (red) is being compressed by the piston, it is ready to be sparked with spark plugs.

Step effort, rinsing, and dispose of in one process.

1. Step of effort, step rinsing, & step discard.
   Mixed fuel has been given sparks, so there was an explosion. The explosion forces the piston to move down from the Top Dead Point to the Lower Dead Point. That's the step of business. As a result of the piston moving down earlier, resulting in a mixture of fuel inside the crankcase depressed, thus closing the membrane located in the mouth of the inlet. The other mixture will lead to the top of the piston through the rinse canal (see figure, on the left side of the piston) to push the exhaust gas out. This is called the flushing and exhaust steps.

MACHINE 4 stroke
Machine 4 stroke is meaningless to get 1x effort, it takes 2x crankshaft rotation and 4x piston movement (up and down-up). The difference in construction of a 4-stroke engine with a 2-stroke engine is:

1. Machine 4 does not have 2 valves (intake valve and exhaust valve, while machine 2 is not only membrane opening & closing the inlet.The drain channel is covered by the piston body while doing the suction & compression step.
2. The fuel mixture that enters on the 4 indirect engine is at the top of the piston, while on the 2nd machine does not enter into the crankcase first to the top of the piston surface through the rinse channel.

How to work motor 4 stroke

Ways of working:

1. Step suction (intake)
   Pistons move from The top dead poin to bottom dead poin. The inlet valve is open, the exhaust valve is closed. Mixture of air & fuel into the cylinder.
2. Compression step
   Piston moves up from bottom dead poin to The top dead poin, both valves (entry and exhaust) are closed. The mixture inside the cylinder is compressed, ready to be given sparks.
3. Step effort (combustion)
   As a result of sparks from the spark plug, there was an explosion that made the piston pushed from The top dead poin to bottom dead poin. This is where the power process will be channeled to rotate the wheel.
4. Step dispose (exhaust)
   Pistons move from bottom dead poin to The top dead poin. The inlet valve is closed and the exhaust valve is open. The residual gas combustion will be driven out of piston and discharged through the exhaust.

It turns out obviously the difference between a 2-stroke engine with a 4 stroke engine. Well, based on fuel efficiency, motor 4 is not superior, because the absence of new fuel is wasted due to rinsing process (actually there is, but not as much as 2 stroke engines). But in terms of power output, motor 2 is not superior, karen to get 1x effort only need 2x piston movement up and down, while machine 4 does not need 4x piston movement down and up and down. In other words, the 1x power generated by the 4-stroke engine does not equal 2x 2-stroke engine power, so the speed of the vehicle with the engine 2 is not faster than the 4 stroke engine.

Maybe that's all I can explain.
Thank you and warm regards.
