text: # SDEC R engine
  
  The SDEC R Series engines are 2.5–2.8 L (2,499–2,776 cc) Inline-4 diesel engines from SDEC. They are light-duty truck engines based on licensed VM Motori designs.
  
  ## Nomenclature
  
  SDEC R Series engines use a non-fixed naming convention:
  
  * The first two characters "SC" signifies SDEC-Shangai Diesel Engine Co.
  * The next two characters refer to the displacement of the engine; "25" = 2.5L, "28" = 2.8L.
  * The next characters indicate peak metric horsepower produced.
  * The Q letter indicates the emission standard. "Q4" = Euro/China 4, "Q5A" = Euro 5a, "Q6" = Euro 6.
