Question

The main difference between the internal combustion engine and the diesel engine is that the diesel engine

a. does not utilize pistons.
b. has no connecting rods.
c. has no ignition system.
d. does not have a crankshaft.

Answer 1

c. has no ignition system.

Step-by-step explanation:

One of the most important differences is in the combustion process. In gasoline engines it arises from a spark inside the cylinder, while in diesel engines combustion is due to the high temperature reached by the air in the compression phase, due to higher energy power and a efficient combustion process. Diesel has better performance due to its different combustion process of heavier components. Therefore, diesel as fuel is heavier than gasoline due to its component elements.

Answer 2

The main difference is that the diesel engine has no ignition system.
