Product Details

Two Stroke Diesel Engine Model
 
 
This is an excellent model of a two stroke diesel engine, great for hands on display of what goes on inside of a two stroke engine.  The model's bulb is powered by electricity at positive and negative power nodes, use wire and posts of 9 volt battery.  The engine action is powered by a wheel crank.
 
In four stroke engines there are two unproductive strokes, the suction stroke and the exhaust stroke.  Dugald Clark in 1878 figured an alternative method that uses the suction and exhaust to power an additional stroke for each revolution of the crankshaft.  Because of this, the power output of the two stroke engine doubled that of the four stroke. 
 
Diesel engine is based on diesel cycle.  The air sucked through spring loaded inlet valve when the pressure in the crankcase reduces due to upward motion of the piston during compression stroke.  Near the end of the expansion stroke piston uncoveres the exhaust ports and the cylinder pressure drops.  In diesel engine air, instead of fuel-air mixture is inducted during the suction stroke.  Because of the high pressure the temperature of operation is much higher giving the ability for self ignition of the fuel which is injected into the combustion chamber.
 
The two stroke gas engine has two disadvantages, fuel loss and idling difficulty.  The way fuel loss is avoided is by using fuel injection instead of a carburetor.  Two strokes engines are lighter, more powerful, and the work to overcome friction of the exhaust and suction stroke is saved.  High speed two stroke engines are less efficient due to volumetric efficiency and also two stroke engines tend to cause more consumption of lubricating oils.
 
Diesel engines produce very high power and are generally used as two stroke engines for things such as ship propulsion.
