The Audi 80 models are completed with five petrol engines. The scale of engines stretches from economic 4-cylinder motors to comfortable and powerful options, such as single-row 5-cylinder and V-shaped 6-cylinder engines. In particular, it:
- 2,0-liter 4-cylinder engine in capacity of 66 kW (90 hp)
- 2,0-liter 4-cylinder engine in capacity of 85 kW (115 hp)
- 2,3-liter 5-cylinder engine in capacity of 98 kW (133 hp)
- 2,6-liter V-shaped 6-cylinder engine in capacity of 110 kW (150 hp)
- 2,8-liter V-shaped 6-cylinder engine in capacity of 128 kW (174 hp)
Though outwardly almost not changed, present Audi 80 car became much more adult" in comparison with generation predecessor. The shortcoming which earlier often criticized, – too small luggage carrier – is completely eliminated now. Besides, on Audi now there is the new back bridge, providing to the car considerable steadier behavior during movement.
Both 4-cylinder engines with which Audi 80 is completed, have volume of 2 l. This two-liter 4-cylinder engine is well-known on numerous modeling series predecessors. Its roots leave in 1972 (then its volume still made 1,3 and 1,5 l).
The increase in volume to 2 l occurred in 1988 on the basis of "grown up" to this time to 1,8 l of the unit. Additional cubic centimeters go on advantage first of all to a torque.
Each time to increase in volume other novelties, this time reacting to warmly tension roller keeping constant level of a tension of the GRM gear belt at various temperatures of the engine are added. This measure led to increase in service life of a gear belt. Something almost already by itself разумеещееся: valves are put in action by hydraulic pushers not demanding servicing.
Distinctions of both 4-cylinder engines consist mainly in preparation of gas mixture: while the 4-cylinder engine in capacity of 66 kW (90 hp) works at the normal AI-92 gasoline not containing lead arriving through one nozzle (the central injection), the version in capacity of 85 kW (115 hp) is supplied with system of injection of Digifant. In this case through own nozzle in each cylinder AI-95 gasoline (euro super) arrives. Bezdetonatsionny adjustment of an advancing of ignition (you will find an explanation in head ignition System) does possible operation of the engine and on AI-92 gasoline, and without any unpleasant consequences for the motor.
The reliable and unpretentious 2,3-liter 5-cylinder single-row engine for last years constantly was exposed to technical improvements. So, for example, it is supplied already mentioned reacting on warmly tension roller which provides a tension of a gear belt of a camshaft at constant level.
In it 5-cylinder the engine with system of injection of KE-III-Jetronic and ignition system with programmed control process of combustion of fuel is supervised by the sensor of a detonation established on everyone cylinder so this power unit optimum uses unleaded AI-95 gasoline at extent of compression 10,0:1. As substitute it is possible to use and AI-92 gasoline (normal).
The maximum capacity of 98 kW (133 hp) the 5-cylinder engine reaches at 5500 rpm, and the maximum torque of 186 N • m at 4000 rpm. The wide chart of a torque provides dynamism on low and average frequencies of rotation of the crankshaft.
The V-shaped 6-cylinder engine is equipped with electronic system of injection of MPI fuel with a measuring instrument of weight of air which supervises quality of a mix for each cylinder separately and consequently reduces fuel consumption and reduces quantity of harmful substances in the fulfilled gases. Behind process in the cylinders, created at combustion, two sensors of detonation combustion which are carrying out selective control of a detonation "watch". It prevents negative consequences which can arise at fuel application with too low octane number.
Interesting detail of this engine is so-called the inlet wire with changeable length of a path which provides existence of a high torque in a wide range of frequency of rotation. Six valves in the inlet pipeline with changeable length of a path are put in action by depression and cope depending on number of turns: to 4000 rpm they form long pipelines for achievement of a high torque. Over 4000 rpm – short pipelines for achievement of bigger capacity. The V-shaped 6-cylinder Audi engine reaches the maximum torque of 245 N • m at 3000 rpm on AI-95 gasoline. At AI-98 gasoline application (euro super plus) it develops 250 N • m. In a wide range of frequencies of rotation from 2000 rpm to 5000 rpm at the disposal of the driver there are at least 220 N • torque m.
The system of ignition of the V-shaped 6-cylinder engine does without the mechanical distributor of ignition.
For the first time on Audi 80: 6-cylinder V-shaped engine.
Streams of the fulfilled gases of the left and right number of cylinders leave in two catalytic converters working separately. Thanks to existence of two warmed the lambda probes is provided separate regulation of the fulfilled gases for each number of cylinders.
The 2,6-liter 6-cylinder engine appeared as slightly "grown thin" version only in August, 1992. Slightly modified system of injection (MPFI) applies other method of measurement of air. Also in this engine there is no inlet gas pipeline with changeable length of a path. But at developed 110 kW at 5750 rpm and 225 N • the m at 3500 rpm about a lack of capacity cannot be and speeches.
Functioning of the inlet gas pipeline with changeable length of a path: at the left a way of let-in air at number of turns of smaller 4000 rpm, on the right a way of let-in air at the number of turns exceeding this size.
