5.7 Hemi Engine

In today’s economy we are all looking for ways to save a few dollars, and still have power when driving our vehicles. One of the ways I see to do this is to invest in a 5.7 Hemi V8 engine. For me when I see a hill coming up I want to know that I am going to have the power in my car to carry me to the top without any hesitation. If I am taking my pickup out hunting or just 4-wheeling I need something that is going to see me through to the end without losing any power. I want the power to show up my friends and family when we are competing.

5.7 Hemi Engine

The thinking behind the original Hemi engine when Chrysler was designing it in the 1950’s was to give the engine horsepower through more efficient ways than the rest of the engines on the market. The uniqueness and difference in the building of this engine has required that other main features of the Hemi be designed differently. The combustion chamber on the Hemi is shaped like bowl changing the shape of the pistons, making them circular also. Instead of one spark plug per cylinder they have put two in each one. Instead of the valves going in straight they are set at an angle. The cylinder heads are larger to allow for the different directions that the intake and exhaust valve stems have to face. All the changes in the way parts sit in the engine and new technology gives the combustion chamber more room to allow the air to flow more evenly through and mix with the fuel for a better firing system.

The new 5.7 Hemi has even more horsepower per cubic inch than the previous versions. Chrysler uses a multi displacement system that will allow two cylinders on each side of the engine to be shut down when hauling a light load in order to save on fuel. The new Hemi 5.7 also has variable camshaft timing and it uses an oil-controlled valve that advances or slows down the camshaft timing.
