Mazda Introduces First Compression Based Gasoline Engine
This translates into an engine that produces more horsepower and torque per gallon of fuel than a traditional powered gas engine. The announcement is thrilling environmental activists as this means less harmful emissions output per engine as well as less trips to gas station. Diesel engines for passenger vehicles have been widely popular in Europe years but not so much in the American market. Diesels have the perception of being noisy and polluters.
