This engine is a further development of the very succesful "A-Kent" engine. For the 1976 model year, the Kent engine was modified for transverse installation in the engine compartment of the new Ford Fiesta. The engine has been shortened by 30 mm and the number of main bearings has been reduced from five to three. The engines were now called "Valencia". With the appearance of the third series of the Ford Fiesta in 1989, the new "HCS" engine was introduced. This further development of the "Valencia" - which was named Valencia-HCS (high compression vortex; high compression, swirled) - had a different cylinder head with modified combustion and intake ports, the number of main bearings was again raised from three to five.
