It is usually just the one, but there are made with more than just the one cylinder. 2-stroke is most used in mopeds, chainsaws and lawnmovers.
A two stroke engine has half the strokes of an otto (or four stroke) engine, therefore it takes two crankshaft roatations to complete a cycle on a four stroke engine and only one revolution in a two stroke engine. There are several types of two stroke engines, the different types have to do with how the receive the air/fuel mixture, also you have two stroke diesel engines.
Explain the advantages of four-stroke engine over two-stroke engine
A two-stroke engine is an internal combustion engine that completes the process cycle in one revolution of the crankshaft (an up stroke and a down stroke of the piston, compared to twice that number for a four-stroke engine). This is accomplished by using the beginning of the compression stroke and the end of the combustion stroke to perform simultaneously the intake and exhaust (or scavenging) functions. In this way, two-stroke engines often provide strikingly high specific power, at least in a narrow range of rotational speeds. The functions of some or all of the valves required by a four-stroke engine are usually served in a two-stroke engine by ports that are opened and closed by the motion of the pistons, greatly reducing the number of moving parts.
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
A four stroke internal combustion engine can have any number of pistons, from one to one million. They usually have even numbers in order to maintain engine stability. The "four stroke internal combustion" signifies the type of engine. There are two stroke internal combustion engines, mostly one or two cylinder engines used in lawn mowers. An internal combustion engine is one that ignites an air fuel mixture within itself and uses the resulting explosion for power. There are external combustion engines, which are usually powered by steam heated in a separate container and pumped into the engine. Four stoke engine utilize a four step (or stroke) process in order to run. The steps are the intake stroke, where the engine breaths in air and fuel, the compression stroke, where it squeezes the air and fuel, the power stroke, where it ignites the air fuel mixture, and finally the exhaust stroke, where it pushes the remains of the ignition out. See the attached link for a graphic description of how two and four stoke engines work.
Detroit diesel engine is an example of two stroke engine
two stroke
You freeze up the engine
suction stroke and exhaust strokes are the two strokes involved in 2 stroke engine....
Yes, a Vélosolex has a two-stroke engine.
You can use four stroke oil for a (very) limited period in a two stroke engine in an emergency. However it is not formulated for two stroke engines and is not recommended.
No it isn't fatal, but it would smoke quite a bit, because a two stroke engine needs two stroke oil mixed in the petrol, and a four stroke just needs petrol.
