The line of 4-cylinder VW EA827 engines was produced by the company from 1972 to 2002 and was installed on almost all mass models of the concern under the Volkswagen, Audi or Seat brands. After the end of production in Europe, the units of this series were assembled in China until 2013.
The EA827 series of compact 4-cylinder overhead cam engines was developed by an Audi engineering team back in the late 60s of the last century and was first introduced in 1972 simultaneously with its new Audi 80 model in the back of the B1. Soon a similar Volkswagen Passat B1 appeared with the same units under the hood.
The first line consisted of three motors, the brief characteristics of which are summarized in the table:
These engines had a progressive design for their time: on top of the cast-iron block was an SOHC aluminum cylinder head with a camshaft driven by a belt. A distinctive feature of these power units was the presence of an intermediate shaft, which actually pierced through the cylinder block, transferring torque from the belt on one side of the engine to the oil pump shaft or ignition distributor on its other side.
Also, when designing the engine, the distance between the cylinder axes of 88 mm was chosen, which subsequently limited the working volume of engines of this family to two liters. The intake and exhaust here were on the one hand, and the power supply system was naturally carbureted.
The EA 827 series received its first changes just a year after the start of its production. By increasing the cylinder diameter from 76.5 to 79.5 mm, the 1.5-liter engine became a 1.6-liter. Power also increased, the YS modification with Bosch K-Jetronic injection developed 110 hp and 137 Nm.
Then the working volume of these power units increased more than once. By changing the piston stroke from 80 to 86.4 mm, a rather rare 1.7-liter engine was obtained, which then turned into a 5-cylinder 2.1-liter engine of the EA828 series. In 1981, the cylinder diameter increased again from 79.5 to 81 mm and a new 1.8 liter engine appeared.
The last major changes to this engine family came in 1986 and 1988. First, the cylinder diameter was increased from 81 to 82.5 mm and received a 1.9-liter power unit, and then the piston stroke from 86.4 to 92.8 mm and received the largest engine in the line at 2.0 liters. Around the same time, the configuration of the 1.6-liter engine changed from 79.5 × 80 mm to 81.0 × 77.4 mm.
The real dawn of the EA827 family came in the eighties of the last century. At the same time, dozens of modifications with different displacements, various fuel injection systems and even 16-valve versions with two camshafts were in production.
We summarized the characteristics of the most popular power units in a table:
Separately, it is worth talking about the G60 sports power units equipped with a compressor. These rare 1.8-liter engines were installed on the second Golf, Passat B3 and Corrado. In total, there were two versions of the engines: 8-valve for 160 hp and 16-valve for 210 hp.
In 1996, power units of the new EA113 series, similar in terms of displacement, appeared, which, although they were based on their predecessors, received many changes. Firstly, the intermediate shaft disappeared, and the 1.6-liter engine replaced the cast-iron block with aluminum.
Interesting hybrids were the latest 1.8-liter longitudinal engines. They received a 20-valve cylinder head like the engines of the EA113 line, including turbocharged ones.
The last representatives of the EA827 family were the 2.0-liter ABA, AWG and AWF units, these engines were used to equip the fourth-generation Golf-based convertible until 2002.
However, outside the countries of the first world, the history of the power units of this series continued. In Brazil and South Africa, the Gol and Citi Golf models were equipped with these engines until the end of 2009. And in China, the Santana model, popular in the local market, with such an engine was produced until 2013.
The 1.8-liter Audi JN engine was produced at a German plant from 1984 to 1991 and was installed on the Audi 80 in the B2 and B3 body, as well as on the second generation Volkswagen Passat. This power unit was distinguished by the presence of a KE-Jetronic distributed fuel injection system.
The 1.6-liter Volkswagen PN carburetor engine was produced from 1985 to 1992 and was installed on the second generation of the most famous models of the German concern: Golf and Jetta. A similar power unit was installed on the Audi 80 in the B3 body under a different PP index.
The 1.6-liter Volkswagen AFT engine was assembled at the company’s plant from 1995 to 1999 and was installed on such popular concern models as the third Golf, fourth Passat and Vento. This unit was one of the first representatives of the new family with an aluminum block.
The 1.6-liter 8-valve Audi ADP engine was produced by the company from 1994 to 1998 and was installed only on two related models: the first generation A4 and the B5 Passat. This power unit quickly gave way to the AHL motor of the new EA113 family.
The 1.8-liter Volkswagen RP mono-injection engine was produced from 1986 to 1993 and was installed on the second Golf or Jetta similar to it, as well as the Passat B3 and Seat Toledo. There were modifications of the unit with two types of injection: Mono-Jetronic and Mono-Motronic.
The 1.8-liter Volkswagen AAM or Golf 3 1.8 single injection engine appeared in 1990 and until 1998 was installed on such popular models as Golf 3, Vento, Passat B3 and B4. There was an upgraded version of this power unit with its own ANN index.
The 1.8-liter Volkswagen ABS mono-injection engine was assembled from 1991 to 1999 and installed on the third Golf, Vento, Passat to the B3 and B4 body, and some other Seat models. This unit at one time was very widespread in many automotive markets.
The 1.8-liter Volkswagen ADZ 8v engine was produced by the concern from 1994 to 1999 and was installed on the third generation of the popular Golf, Passat B4 and a number of cars from Seat. This mono-injection power unit is essentially an updated version of the ABS motor.
The 1.8-liter Volkswagen PF engine was assembled by the German concern from 1987 to 1991 and installed on the second generation of Golf and Jetta models, Passat B3 or Corrado coupe. The power unit stood out among analogues by the presence of a Digifant injection control system.
