Petrol engines[edit]EA 111The EA111 series was introduced in the mid 1970s in the Audi 50 and later the VW Polo. It is a series of water cooled three- and four-cylinder petrol and Diesel engines in a variety of sizes. The overhead cam engine features a crossflow cylinder head design and directly-driven auxiliary units. The exhaust side is in driving direction.[edit]Three cylinders[edit]55-70 hp 1.2configurationwater cooled 1198 cm³ inline threehead(2 V) aluminium, SOHC, two valves per cylinder, 10.3:1 compression(4 V) aluminium, DOHC, four valves per cylinder, 10,5:1 compression ratioblockaluminium, four bearings, balancer shaft, 76.5 mm bore × 86.9 mm stroke, 0.88 ratio, 399 cm³ per cylinderfuelelectronic injectionoutput(2 V) 40 kW (55 hp) at 4750 rpm, 108 N·m (80 ft·lbf) at 3000 rpm(4 V) 47 kW (64 hp) at 5400 rpm, 112 N·m at 3000 rpm(4 V) 51 kW (70 hp) at 5400 rpm, 112 N·m at 3000 rpmapplicationVW Fox, VW Polo (PQ 24) and Skoda FabiareferencesVW AG (2005-04-04).
