DDiS are turbocharged diesel engines with the Common Rail direct fuel injection system, installed on Suzuki cars. They have been produced since 2003. These engines are known for their reliability, high performance, and fuel efficiency. Today they are available for most Suzuki models.
Features of DDiS engines
These engines are a version of popular engines produced by General Motors, Groupe PSA (now Stellantis), and Groupe Renault. They have a 4-cylinder cast iron or aluminium engine block. The cylinder head is made of aluminium. They work with the Common Rail fuel supply system made by Delphi, Bosch, or Siemens. A chain or a belt is used in the valve timing mechanism drive.
