Dynano Engine Family
C/Classic series: An inexpensive cast iron design for export and license production in developing nations, with a high degree of commonality with the pre-1980 P/Power and S/Sport series engines.
P/Power series: A design that balances power, cost, and fuel economy. In more modern engines, this means the omission of variable valve lift.
S/Sport series: The premier series of the Dynano engine family. Common features include the use of super fuel. More modern engines feature the full range of advanced technologies, including individual throttles for fuel injectors, variable valve timing, and variable valve lift. The series was discontinued between 1975 and 1990 due to the lack of super unleaded fuels.
