I. C. Engine, an acronym for an internal combustion engine, is an engine in which fuel ignition and combustion occur inside the engine. It works on the principle that the charge is ignited inside a combustion chamber under very high pressure.
The term internal combustion engine usually refers to an engine in which combustion is intermittent, such as the more familiar two-stroke and four-stroke piston engines, along with variants, such as the six-stroke piston engine and the Wankel rotary engine.
Four-Stroke Engine:
The petrol engine works on the principle of the otto cycle, also known as the constant volume cycle. The spark plug fitted at the top of the cover initiates the ignition of the petrol. In a four-stroke engine, all the events, i.e., suction, compression, power, and exhaust, are completed in two revolutions of the crankshaft.
Four-Stroke Diesel Engine:
The basic construction of a four-stroke diesel engine is the same as that of four stroke petrol engine, except instead of the spark plug, a fuel injector is mounted in its place. A fuel pump supplies the fuel oil to the injector at higher pressure. It works on the diesel cycle or constant pressure cycle.
Two-stroke Petrol Engine:
The two-stroke engine requires one revolution of the crankshaft or two piston strokes to complete the cycle of events (i.e., suction, compression, power, and exhaust). The two-stroke petrol engines also work on the principle of working the otto cycle.
Two-Stroke Cycle Diesel Engine:
The Two-stroke Diesel engine works like the Petrol engine, but it injects diesel at the end of the compression stroke.

Excellent presentation! Truly seminal in educational documentaries. A lot of hard work has obviously gone into all of their instructional video lectures and all are truly outstanding, with super graphics, while remaining easy to follow and comprehend. They are so good in fact that the rather clipped and poor English and syntax, together with an outdated computer voice-over are overlooked and completely forgiven. I only mention the last so that the producers can take onboard those small suggestions and make their future “video lessons” excel even more. Edit: I subscribed because all are so good.

[@Trinexx42]

The biggest difference is between the two stroke gasoline and two stroke diesel. In a two stroke gasoline engine with crankcase compression, the air is pulled through the crankcase. If the crankcase had a wet sump like 4 stroke engines, then the air would pick up the engine oil and it would run out of oil way too quickly and also mess with the air fuel ratio. This is why oil is mixed into the gasoline. The oil in the gas is necessary to lubricate the crankshaft due to the lack of the wet sump. In a two stroke diesel, crankcase compression is not viable because only air can pulled into the engine. With a wet sump, any oil picked up in the air would cause preignition, which can destroy the engine. And because the fuel is injected later, premix with a dry sump can't be used either. This is why 2 stroke diesel engines need to have forced induction, either a supercharger or a turbocharger or both. They can't use the crankcase compression to force the fresh air into the cylinder. And because they don't use crankcase compression, they will have a wet sump and a dipstick like a 4 stroke engine.

[@mechguy8459]

Such a good video on 4-stroke & 2-stroke engines ❤️

[@TheEngineersPost]

Glad you liked it!

[@xyzconceptsYT]

Simple and clear explaination.

[@elchupacabra1666]

Some clarification about 2-stroke engine thermal efficiency: 2-stroke engines are NOT necessarily less efficient than 4 stroke engines. Big 2-stroke ship engines are one of the MOST efficient ICE engines with thermal efficiency over 50%. Also, diesel 2-strokes does not have fuel losses due to scavenging. Diesel 2-strokes and crankcase compression gasoline 2-strokes are totally different engines.

I have always wondered why nobody has made a 2 stroke gasoline engine like the 2 stroke diesel engine. Would it work better?

[@sleepypants6314]

There's plenty 70s to 90s motorcycles with 2 stroke gasoline engine. They all wild on the road. Their 2 stroke 150cc can make 500cc 4stroke want to sell their bike

[@degenerate_kun_69]

It needs more lubrication compared to diesel so the wear would be phenomenally high, also 2 stroke diesel engine wear out faster than 4 stroke engines

[@marrapusaidileep781]

2 stroke gasoline engines are already made in 19th century only it used in RX100 bikes it is banned in India because this bike is more powerful in old times. These bikes are used by the chain snachers police can't chase them because of speed of bike and it is banned because more air pollution by this bike engine

[@randyschmittou8708]

Just about every chainsaw has a gas 2 stroke engine. Most dirt bikes from the 1960s to the 1990s were 2 stroke gas engines. They were phased out because of the pollution. They tend to smoke more than 4 stroke engines. But I have owned a few 2 stroke dirt bikes and they have INSTANT THROTTLE RESPONSE! They were a real Blast to ride!

[@mrdjangofreeman5560]

Great job ! One comment: there is NO "explosion", and piston must NOT see an "explosion", but a combustion gas burning front flame, hopefully. Otherwise, piston would quickly get destroyed :-)

The heat generated at the top of the head during the combustion is wasted in these type of engines. However, in opposing piston engine, the heat generated is used to push the opposite piston creating double the power.

Higher fuel consumption is definitely a disadvantage for gasoline 2-strokes. But I don't think it is a disadvantage in 2-stroke diesel... you know, injects fuel when everything is sealed... Regardless of all those advantages and disadvantages, 2-strokes sound nice, especially diesel ones.

[@benkiptoo9189]

so whats the use of a glow plug in the diesel engine if the fuel self ignites with the use of the heated pressurized air.

[@JulianA-tr6pt]

The heat has to come from somewhere, initially. "In a diesel engine, a glow plug is a heating device used to aid starting of the engine in cold weather." Many diesel engines are known to be difficult to start in cold weather. Some glow plugs are manually operated during startup, or are cycled on during a cold start, and they shut off once the engine is running/up to temperature. On the other end of things, read about/watch diesel engine runaways.

When you were comparing the advantages of a 4 stroke engine and a 3 stroke engine, you compare a gasoline 2 stroke engine to a 4 stroke engine.
