The crankshaft, pistons, cylinder block (with cooling fins- most two-stroke engines are air cooled), valves, camshaft, timing chain, carburettor, fuel pump and sparking plugs make up the essential body of the engine. There are also the spark plug leads, exhaust system, and (on a motorbike) the drivewheel that turns the driving chain that moves the rear wheels (N.B. most scooters don't have the latter, as they are direct drive). Two-stroke car engines have a more elaborate ignition system, featuring a distributor and ignition coil. A water-cooled two-stroke engine will also have a water pump and radiator too.
Explain the advantages of four-stroke engine over two-stroke engine
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
Detroit diesel engine is an example of two stroke engine
two stroke
Gas mixed to rich
You freeze up the engine
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.
suction stroke and exhaust strokes are the two strokes involved in 2 stroke engine....
what are the two main components of the atmosphere
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.
