Advantages of internal combustion engine over wind-mill are as follows. We cannot get strong winds in sufficient quantity at all places, so wind-mill does not work at all places. But on the other hand, internal combustion engine can be used at all places.
Energy is also released in the form of heat and light when we burn compounds in air and oxidized them. During combustion or burning, the oxygen of the air combines with the compound and releases energy in one step.
Some of the most important differences between Respiration and Combustion are respiration in slow process. That is, oxidation of food in the body takes place slowly whereas combustion usually takes place at a much higher temperature.
The main advantages of an internal combustion engine over the external combustion engine are : 1. An internal combustion engine is compact and lighter 2. An internal combustion engine is quite safe to use 3. An internal combustion engine can be started immediately.
Difference between Diesel Engine and External Combustion Engine are The power in diesel engine is derived from hot gaseous products obtained by combustion of diesel whereas the power in the steam engine is derived from steam under pressure.
