What engines used in nascar

Ever since its creation in the 1940s, NASCAR has been known for its speed and power– things that are made possible by the incredibly powerful engines found within each of its cars. Today, drivers compete with car models outfitted with specially-tuned engines based on one of two main designs. More about used engines.

The first type of engine is known as a carbureted engine, which runs on a combination of gas and air. These engines use traditional carburetor technology to mix fuel and air into a combustible mixture that then gets ignited inside the cylinders by spark plugs to create power for the vehicle. Carbureted engines have been used in NASCAR races since the 1950s but new modernizations have improved their performance over time. From increasing horsepower through changes to intake manifolds and camshaft profiles, these vehicles can now run faster than ever before while relying on this same basic design principle that's been around for generations.

The second type of engine used in NASCAR is a multi-valve fuel-injected model which utilizes cutting edge computer technology to coordinate airflow into the cylinder just right so it can create more power than other traditional engines designs can achieve. These types of motors are referred to as "electronic fuel injection" (EFI) systems because they use computers instead of classic mechanical components like carbs or distributors for coordinating how much air/fuel goes into an individual cylinder at any given time . This has enabled engineers designing our racing machines today to squeeze even more performance out of them without sacrificing safety or reliability – something no one could do using only older mechanical components from decades prior.
