Audi A4 representation
In 1972 the Audi 80 model for the first time was presented. Since then on the market 4 generations of models from Ingolstadt arrived. All of them could win a strong place in the market thanks to solid technology and unostentatious external shape, it is proved also by statistics of the admission of vehicles. А4 in any relation is the proof of it and the worthy successor.
The tradition obliges
In 1972 automobile plant in Ingolstadt, having let out Audi 80 which thanks to the easy design and the compact sizes, comfortableness and spaciousness of salon and a luggage carrier, and also and to an exemplary running gear established to modern engines a high standard of the car of middle class. Audi A4 continuing traditions of Audi 80, arrived on the market in November, 1994. In the following Audi model meaningly refused the large-sized external sizes. Nevertheless thanks to skillful use of space, increase in a track and wheel base it was possible to improve considerably for sitting in salon the relation of internal length of a body to base.
Along with two new pyatiklapanny engines with working volume of 1,8 l, in Audi A4 the processed four-cylinder dvukhklapanny engine with working volume of 1,6 l with newly designed for А4 a head of the block of cylinders with cross-section movement of a stream of air is offered. Besides, two engines which are already known on Audis 80 are used also: V6 with working volume of 2,6 l and 2,8 l. Everyone it:
At such gradation choice possibility between two power plants of identical capacity because as the four-cylinder engine with working volume of 1,8 hp a turbo-supercharging, and V6 with working volume of 2,8 l possess identical capacity in 110 kW is of interest. At identical capacity there are distinctions in conceptual characteristics: that for the buyer is priority in the engine, the choice between the increased profitability or bigger comfortableness and smoothness of a course can be made.
Technology of the pyatiklapanny engine
Engine capacity along with various parameters, for example working volume and number of turns, considerably depends on that, gas exchange how fast can be carried out. The more fresh gas for the same unit of time can get to the combustion chamber, the more intensively a capacity exit. The majority of Audi engines has a long course, it means that a piston stroke more than diameter of the cylinder. Engines with a long course allow to create short designs, they it is easier than engines with a short course, possess smoothness in work, especially idling, and differ, first of all, that already on low turns reach the maximum torque.
Philosophy of adjustment of the engine
The high density of traffic on our streets demands other concept of the engine different from those that existed in the 80th: the size of the maximum capacity, and equation of fuel consumption, the range of offered capacities, character of exhaust gases and noise is in demand not. The design of the engine chosen by Audi with a powerful torque in the bottom range of frequency of rotation allows movement on low turns and, therefore, appreciable decrease in fuel consumption.
