Next, let us consider in more detail the features of the engines of the car in question.

Petrol engines

Motors with four cylinders are a modification of the previous engines, installed on the earlier versions. To improve the torque allowed to increase the volume of the unit to two liters. There are two versions of these engines on the "Audi 80" (B4). The relay, the injection system and consumed fuel are the main differences between them.

The variant with a capacity of 90 "horses" uses AI-92 fuel, the fuel is injected through one nozzle under the throttle valve. An analog of 115 horsepower is equipped with a fuel delivery system of the Digifant type. As fuel, the "Euro Super" gasoline is used, which is supplied to the combustion chamber by means of valve type injectors.

The main difference between the power unit and the five cylinders is its design. Crankshaft crankpins are located at an angle of 72 degrees, and the unit itself is equipped with a pair of counterweights for each cylinder. Also, vibration damping occurs due to the presence of an imbalance on the flywheel and vibration damper.

V-6

This motor is equipped with an automatic multi-point fuel injection system. In addition, there is an air mass flow meter with a filament to be heated. This design allows you to supply fuel to the combustion chamber of each cylinder, which affects the economical consumption and reduction of harmful emissions into the atmosphere. Two sensors are used to adjust the supply of the air-fuel mixture, which avoids engine breakdowns when using gasoline with an unsuitable octane rating.

The V6 engine is equipped with a pair of overhead camshafts. They are activated by means of toothed belts. The valves of these elements are adjusted by poppet-type pushers. In the space between the rows of cylinder heads is a volumetric intake manifold. It is a feature of the considered motor, as it has a variable configuration of the internal cavity, which provides high ripple on a wide range of rotations of the power unit.

The ignition unit of the motor in question is not equipped with a mechanical distributor, but is controlled by an electronic system. The exhaust gases from both cylinder rows are fed to a pair of catalysts that are independent of each other. Two heated probes, also insulated, are included in the right and left rows of cylinders. They ensure the emission of exhaust gases with minimal inclusion of harmful substances.

The six-cylinder engine, the estimated capacity of 2.6 liters, has a modified injection system with a mass flowmeter of the incoming air mixture. In addition, it does not provide a gas pipeline with a configurable configuration. Nevertheless, the power of the engine remained at 110 kW with a torque of 225 Nm (3500 rpm).

Diesel engine

Diesel "Audi 80" (B4) is presented in two variations. The TD version with turbocharger has a capacity of 1.9 liters, power - 55 kW. It was installed on cars that were produced before mid-1992. The torque of 150 Nm was guaranteed at 2200 rpm. For later modifications, the TDI power unit was assembled, which was also rated at 1.9 liters, with a capacity of 66 kW. To provide a torque of 150 Nm, 2400 rpm was required.

Since the end of 1993, cars are equipped with an improved version of this engine. The torque in it is 202 Nm at 1900 rpm. The cylinder block of diesels is made of cast iron. Its lower part contains a crankshaft, and on the top there are four row-located cylinders. They are surrounded by a coolant circulation jacket. The crankshaft is equipped with five root supports, hence each crankpin is equipped with support from both sides.

Features

All power plants "Audi 80" consistently provide a run of at least 100 thousand kilometers. Diesel engines have a real working life of at least 130,000, especially if the operating conditions make it possible to minimize the start-up of a cold power unit, and the owner does not often drive at maximum rpm. The manner of driving and caring for the unit also affect the period of trouble-free operation of the motor.

An important role is played by regular oil changes, which should be of the type and type recommended by the manufacturer. If the deformation of the valve, connecting rod or piston was not observed during the operation period on a diesel engine, then, with approaching a run of over 100,000 kilometers, it is necessary to prepare for a problematic engine start during the cold season.

What do the owners say?

The car "Audi 80" (B4) reviews from users receives mostly positive. Owners say a lot of pluses, namely:

• Good stability on the road.
• Excellent handling even at speeds over 100 km / h.
• Reliable and durable body.
• Good interior heating system.
• High cross-country ability.
• Quality assembly of all nodes.

There are not so many shortcomings, but there are also some shortcomings. Among the minuses:

• The high price of spare parts for "Audi 80" (B4).
• Rigid suspension.
• Lack of air conditioning.

Since the car in question can only be purchased on the secondary market, its performance and price largely depend on the mileage, technical condition and previous operating conditions.

Finally

As the power unit "Audi 80" can be used as gasoline, and diesel engines. The wider variety is characterized by the first variations. The engines differ in their design and number of cylinders. Machines are equipped with 4-, 5- or 6-cylinder gasoline power units. In addition, they can differ in the number of camshafts that have different types of fuel injection. Among the engines of "Audi" (B4), working on diesel fuel, there are two modifications. All power units in the engine compartment are located longitudinally.
