1.1. New generation of cars Polo since 1995 of release

Car Volkswagen Polo of the third generation has been presented for the first time to 1994 on a motor show in Frankfurt (Germany). The engines established on cars are modernised. An exception is only the engine in volume of 1,6 l, its design is based on the engines let out earlier (diameter of cylinders remained former, the working volume is increased). Models Polo made of 1995, have been equipped by engines in volume 1,0; 1,3 or 1,6 l. All cars of new generation irrespective of volume have been made till the end of 1995 with use of system of injection of gasoline Mono-Motronic through one central atomizer. Since 1996 of possibility of cars Polo have been even more expanded thanks to application of two new four-cylinder engines with the distributed injection. New engines differ the smaller expense of fuel, higher capacity and improved other indicators in comparison with the engines equipped with system of injection of gasoline through one atomizer. The central injection has been kept only for the engine in volume of 1,0 l.

The engine in working volume of 1,4 l, of 60 h.p. has replaced with capacity the engine in volume of 1,3 l, capacity of 55 h.p.

The new engine in volume of 1,6 l, kept former volume and capacity, differs the raised twisting moment, so, and the best dynamics. Thanks to application of the distributed injection the twisting moment of the engine in volume of 1,4 l at frequency of rotation of 2800-3200 mines-1 has increased with 100 to 116 Нм. For the engine in volume of 1,6 l the twisting moment has raised with 128 to 135 Нм at 2800 3400 mines-1.

The maximum speed has increased also at use of the engine in volume of 1,4 l: the car develops 160 km/h (before 155 km/h). Time of dispersal from a place to 100 km/h has decreased with 16,3 to 14,9 with. The maximum speed of models with the engine in volume of 1,6 l has not changed and makes 172 km/h (according to manufacturer), but dispersal and profitability are considerably improved.

At the distributed injection unlike injection through one central atomizer fuel is injected directly ahead of inlet valves of each cylinder thanks to what better distribution of a gas mixture in a combination to rather low values of pressure of injection is reached. Together with the distributed injection in new engines other system всасывания air — through the soaking up mixing pipeline made of fibreglass is applied.

Updatings of car Polo with engines in volume of 1,0 and 1,4 l with a developing roof with the electric drive are made.

Equipment in 1996 under the special order conditioners of cars with engines in volume of 1,4 l became a novelty. Such possibility has appeared thanks to increase in capacity of the new engine in volume of 1,4 l. Till the end of 1995 they were established only on model with engines in volume by of 1,6 l.

All cars of serial releases equip каталитическим with neutralizer.

On cars Polo establish line engines of a cross-section arrangement in a forward part of the car. Cylinders of all engines are cast for a single whole with the block, therefore their replacement for this reason is impossible. The greasing system consists of the oil pump, the oil filter, a manometre, перепускного and редукционного valves. The perepusknoj valve opens when as a result of untimely replacement of oil or for other reasons there is a corking of the oil filter. At excessive increase of pressure of oil the safety valve opens to provide greasing of details. The design of the oil pump which is put now in action by a chain, instead of шестеренчатым a drive from a cranked shaft, as in engines of series Polo of former releases has undergone to considerable change.

In a head of the block of cylinders from an aluminium alloy the camshaft is established. Work of valves hydraulic pushers operate, therefore клапанные backlashes do not demand adjustment. The camshaft is put in action from a cranked shaft by a gear belt which in turn results the water pump.

Forward and back suspension brackets independent. A body of the car of a bearing design.

The suspension bracket of forward wheels consists from амортизаторных racks with twisted springs and triangular cross-section levers, the stabilizer of cross-section stability (except for base model).

The suspension bracket of back wheels consists of a beam connecting longitudinal levers and twisted springs. Hydraulic telescopic shock-absorbers are applied in suspension brackets of forward and back wheels.

Brake system two-planimetric with the amplifier; brakes of forward wheels disk, back wheels — drum-type. The antiblocking system of brakes (ABS) is established on models GL and GLX. It prevents blocking of wheels at braking and keeps controllability and course stability of the car.

The steering is supplied реечным by the mechanism. Since 1996 all models produced in lots, except for models in volume of the engine of 1,0 and 1,4 l, equip with the steering mechanism with the amplifier. Till the end of 1995 the steering mechanism with the amplifier was established only on model with the engine in volume by of 1,6 l. Among the constructive decisions raising safety, presence strong, absorbing energy of blow of longitudinal beams and integrated into space for feet of a cross-section beam. It serves for protection of feet of the driver and the forward passenger. Strong door pillars operate as a safety arch.

Now protection against lateral blow is even more often applied. The elements of rigidity improving in comparison with the predecessors indicators of durability on 30 %, depth of deformation are built in a body and doors of cars Polo on 50 %. Located under the panel of devices the cross-section beam extinguishes lateral blow.

In a back part of the car are located a plastic fuel tank in front of the back bridge and an insert from metal sheet in a back of a back seat. Last protects passengers from being in a luggage carrier in a loose condition of subjects at a head-on collision.

All serial models complete with a mechanical five-speed transmission with the synchronised transfers, in first half of 1996 on cars with engines in volume of 1,4 and 1,6 l established a four-stage automatic transmission.
