In the early days, oil was delivered to an engine's components much differently than it is today. The first engines were lubricated with drip feed systems, which dropped oil into all its moving components, and on ships, there were workers known as "oilers" who filled up pots of oil above the moving parts. Since the beginning of the 20th century, however, internal combustion engines began using a force-feed system, in which oil is pumped around, or forced, to the engine's many parts. Engines today use a completely forced-feed lubrication system, and a critical component of this system is called an…

How Do Diesel Engines Work?

November 6, 2019

From shipping trucks and school buses to yachts and cargo ships, diesel engines power many of the world's vehicles. Diesel engines in boats, trains and trucks transport goods and products all over the world — roughly 94% of freight is shipped in diesel-powered vehicles. Heavy-duty equipment on farms and construction sites is typically powered by diesel engines. Military vehicles and industrial facilities employ diesel engines, as well. Diesel engines are also common in passenger cars, especially in Europe. What makes diesel engines so popular in these applications? Not that long ago, a major answer to that question was price. Historically, diesel fuel was cheaper…
