The Douvrin family is an all-aluminum inline-four automobile engine designed in the early 1970s and produced from 1977 to 1996 by Compagnie Française de Mécanique, a joint-venture between PSA and Renault located in the town of Douvrin in northern France. This engine is designed by the engineer Jean-Jacques His (father of Formula 1 engines from Renault and Ferrari). It was produced in the same factory as the PRV V6, which also is sometimes known outside France as the "Douvrin" V6. The Douvrin engine is also referred to as the ZDJ/ZEJ engine by Peugeot, and as the J-type engine by Renault.^[1]
