SI stands for Spark Ignition. eg. Petrol Engine.
An SI engine ignites the fuel with a spark (SI = Spark Ignition) whereas the CI engine ignites the fuel with heat generated from compression (CI = compression ignition)
An SI engine is a spark ignition engine. A CI engine is a compression ignition engine. SI engines use spark plugs to ignite fuel in the combustion chamber. CI engines use compression in the combustion chamber to ignite the fuel.
Potato plant develops tuber for vegetative propagation in its life cycle.
Mixing of fuel and air depends on type of the engine whether SI or CI. In carburetted versions of SI engines the charge mixes in the carburetion chamber and the mixture is let into the engine. There are direct injection SI engines(GDI) where the injection takes places at various stages of charge compression stroke. In CI engines the fuel is mixed with air in the combustion chamber itself. It is to be borne in mind that these mixing phenomenon are the same be it a new or old car.

You put petrol in it, start the engine, and it goes.

If it only has 2 stages it really isn't an engine. It is possible to describe a heat engine/heat pump with 3 stages, but calculating the changes in thermodynamic properties, work, and heat in each stage can be difficult with only 3 stages. It is also extremely difficult to build an actual pump or engine that only uses 3 stages - you always seem to wind up with one that really has 4 stages with one of them being a very short stage between 2 of the 3 you meant to have. For all practical purposes, you will have at least 4 stages in a heat engine or heat pump.
It will not run.

The DX has the 1.8 liter dual carb engine whereas the Si has the 2.o litre fuel injected engine.
