Mi-Tech DOHC Engine Specsby Justin Cupler
When Kia first introduced the Rio in 2001, it was fitted with a 1.5-liter, four-cylinder engine, known as the Millennium Innovation Technology, or Mi-Tech engine. Kia didn't realize that it had just started a lineup of engines that would compete in the compact car market for nearly a decade. The 2011 Kia Rio makes use of a slightly different version of the Mi-Tech engine from 2001, but the basic concept is still the same.
The 2011 Mi-Tech engine comes as an in-line four-cylinder. This engine has 16 valves in a DOHC configuration, meaning two camshafts sit on top of the cylinder head. The Mi-Tech is a gasoline engine that is fitted with multi-port fuel injection.
The Mi-Tech engine has a 3.01-inch bore, a 3.43-inch stroke and a 10.0-to-1 compression ratio. The bore and stroke combine to create a total displacement of 1,599 cc, or 1.6 liters.
An engine's output is measured by its horsepower and torque ratings. The 2011 1.6-liter Mi-Tech produces 110 horsepower at 6,000 rpm and 107 foot-pounds of torque at 4,500 rpm.
One of the main focuses of compact cars is providing the best fuel economy possible. The 1.6-liter Mi-Tech engine gets 27 mpg in the city and 36 mpg on the highway, when connected to an automatic transmission. When combined with a manual transmission, it is rated 28 mpg in the city and 34 mpg on the highway.
