When you think about diesel engines, you probably think about large trucks and machinery, and maybe a few oddball cars over the years.  But how long has diesel really been around, and why is it used the way it is today? Harold's Used Auto Parts Inc in Philadelphia, PA has the answers you need to become more in-tune with your diesel truck and engine. 

Diesel as a concept has actually existed since the late 1800s, and was first utilized in powering a truck in 1908. It was known early on that diesel engines could be built to run on peanut oil, but at the time, oil was so inexpensive, it just made more sense. Over time, diesel engines have experienced many innovations to make them into how you know them today. 

Diesel engines are the most efficient form of combustion engine there is - but they aren’t commonly used in light automobiles. Until recently, they’ve been louder, dirtier, more expensive to produce, and lower revving than gasoline engines, making them more suitable for industrial usage. However, with extremely high pressure pumps and other advancements in diesel technology, there’s a chance that could change in the future.
