In this video, we're doing a detailed comparison of petrol, or spark ignition, and diesel, or compression ignition engines.

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand ...

Diesel engines don’t have spark plugs; instead, they use the super-heated air created by their high compression ratios to ignite the diesel fuel as it’s injected into the cylinder.

DIESEL ENGINES - They are higher compression than gasoline engines and do not require spark plugs or distributors. They tend to be more durable and less prone to expensive early repairs.
