The 993 cc (1.0 L 60.6 cu in) CB engine appeared in October 1977, for the then-new Daihatsu Charade. There is an 843 cc version called the CD and the extremely rare 926 cc homologation special called the CE. Most common is the 1-liter CB, which was also available as the diesel CL. The engine first appeared in the all-new Daihatsu Charade in October 1977, in 'CB20' form. They have cast iron engine blocks and aluminum cylinder heads, and are of either SOHC or DOHC design, with belt driven heads. The engines range from 843 to 993 cc and have been manufactured in petrol and diesel-driven series. The Daihatsu C-series engine is a range of compact three-cylinder, internal combustion piston engines, designed by Daihatsu, which is a subsidiary of Toyota.
