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 how ...

Both gasoline-burning engines and diesel engines produce power through a process of internal combustion. However, the latter are usually larger, louder, and often dirtier. While many people may not ...

The age of diesel-powered submarines began in 1912, and these subs dominated the waters for more than 40 years, through both World War I and World War II. In the U.S., this era ended when the last ...

Researchers in Wisconsin have developed a concept engine that can run on gasoline and diesel at the same time, with a ...

While diesel engines don't need spark plugs, they do need air ventilation for proper combustion. This is a problem for vessels traveling underwater, such as submarines. Yet diesel submarines exist and ...

You own a diesel-powered vehicle and are thinking of giving it a tuneup. But does your diesel even have spark plugs to change? The short answer is no, diesel engines do not have spark plugs. Instead, ...

Modern internal combustion engines — including those that run on diesel fuel — require a lot of special parts and systems to prevent dumping excess emissions into the atmosphere. Not only are those ...

Turbocharger use is more prolific than ever, and understanding how one works explains why it’s such a popular choice. To understand the benefit of a turbo, we need a refresher on the basics of the ...

Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions ...
