Suppose a large amount of power is required. Which engine would you choose between Otto and Diesel? Why?

Otto engine

Explanation:

As we know that

Power = Torque x speed

So we can say that when speed of engine then power of engine also will increases.

The speed of Otto engine is more as compare to Diesel engine so the power of Otto engine is more. But on the other hand torque of Diesel engine is more as compare to Otto engine but the speed is low so the product of speed and torque is more for Otto engine. It means that when requires large amount of power then Otto engine should be use.
