The EA111 series (EA = development order) are water-cooled three- and four-cylinder in - line engines of the Volkswagen Group built in Chemnitz and Salzgitter . The EA111 series engines are used in the Polo, Golf, Touran, Audi A2 and Lupo, among others.

description

The EA111 series is diverse; of the various engines, mainly those with 1.0, 1.4 and 1.6 liter displacement were built. A classic engine of the 111 series, which was mainly manufactured by Volkswagen Slovakia , is a four-cylinder engine with a bore of 76.5 mm and a stroke of 75.6 mm and a corresponding 1390 cm³ displacement.

history

In the 1970s, VW also developed a diesel engine for the Golf I based on the EA111 . In 1984 VW experimentally built a 1.05 l EA111 engine lengthways into the rear of a Beetle in order to modernize it technically. However, it did not go into series production, the vehicle is now on display in the Volkswagen Auto Museum. In 2010 it became known that the EA111 was being built in China without a license.

In the course of time the engine received significant revisions. From 2000, some versions of the engine were equipped with direct injection and stratified charge and marketed by Volkswagen as FSI. From 2003, the changeover from toothed belts to timing chains took place . From 2005, some versions got a charge and were henceforth referred to by Volkswagen as TSI . These engines had significant problems with the stability of the timing chain.

EA111 in the GDR

In 1982, Gerhard Beil , then State Secretary in the GDR Foreign Trade Ministry , started negotiations with Carl H. Hahn , Chairman of the Board of Management of Volkswagen AG, about the license for the EA111, including a complete production facility. The contract was signed in 1984, and in 1988 the production facility at Chemnitz was handed over by VW to the IFA Kombinat . Complete four-cylinder engines were manufactured for the Wartburg 1.3 and Trabant 1.1 passenger cars as well as the Barkas B 1000-1 van from 1988, and from 1989 on, short engines (engines without cylinder heads) were also manufactured for Volkswagen, and within five years 500,000 EA111s were to be manufactured for Volkswagen.

After the fall of the Wall, production was continued in Chemnitz, 37% of all VW EA111s were made there, 63% rolled off the assembly line at the Salzgitter plant. From 1995 this ratio should be reversed.

The EA111 was installed in the following vehicles of Volkswagen AG with 1,198 cm³ and 1,390 cm³ displacement until 2011:

The power is between 63 and 77 kW.
