What is a HEMI Engine?

Ram 1500

For Charleston and Columbia drivers who are familiar with Dodge or Ram models, chances are you’ve heard the term “HEMI” before. This isn’t just a fancy word that manufacturers made up to sound powerful—it’s an actual engine that Dodge and Ram place only inside their most power-driven models. Although usually more expensive, drivers who opt for a HEMI engine will not only receive superior performance and remarkable towing specs on the road, but will also receive better engine airflow and a vehicle that maximizes compression ratios. What is a HEMI engine? Read on to find out what makes this type of engine so special with our HEMI engine definition.

What is a HEMI Engine?

The word HEMI isn’t made up—it comes from the term hemispherical, which means half of a sphere. Unlike traditional engines, the cylinder head for the combustion chambers on a HEMI is hemispherical, which is one of the biggest differentiators between HEMI engine vs. regular engine types. In addition, the top of the pistons are also hemispherical, allowing the two parts to work seamlessly together.

Because of their shape, the surface volume is decreased and combustion volume is increased, which means the combustion is stronger and doesn’t lose energy because of engine heat. With the hemispherical shape, the combustion chamber allows the engine to maximize compression ratio, and this is what creates the power that comes from these HEMI engines. It’s one of the many things that give Ram trucks an advantage over competitors like the Ford F-150.

These engines were first designed by Chrysler and placed inside planes during World War II. These same engines were then placed inside Chrysler vehicle models in 1951. In 1964, HEMI engines were only found in vehicles designed for racing, and in 1966, the HEMI engine became commonplace on the regular streets of Columbia.
