Test drive UAZ 469 1972 - HB SUV

UAZ diesel hollow

The Russian language is famous for the double meaning of some words. For example, a rogue in relation to a person is an unflattering review, but for the vehicle this characteristic is positive: it means that the cross -country ability is increased. This epithet is perfectly suitable for domestic UAZs. But it turns out that the reserves of the Ulyanovsk Herpers have not yet been exhausted.
 
The heart is extreme
The fact is that when storming with a car of deaths, success depends not only on the geometric parameters of the chassis, weightlift, the characteristics of the transmission and tires, but also on the traction abilities of the engine. Those who traveled without roads on different cars can fully feel it. We explain the uninitiated: in such conditions, the so -called elasticity of the engine is priority, that is, not so much power as the value and nature of the change in torque. In most cases, with the same liter, diesel engines (especially hopeless - atmosphericians) are advantages over gasoline.
However, until recently, the domestic auto industry provided a very limited choice of even gasoline engines of small and medium -sized distribution. What can we say about diesel engines, the lack of which has become especially noticeable with increased demand for commercial cars. Attempts to complete domestic vehicles with imported power units inflated the price almost by half, reducing consumer interest and nullifying the rest of the advantages.
Therefore, having received news from Ulyanovsk about the opportunity to try out cars with diesel engines - domestic ZMZ -514 and Polish Andria 4ST90 in comparison with serial gasoline ZMZ -409 - we immediately went on a business trip.
 
From theory to practice
Bright sunny morning lined up on a picturesque hill near the local cross route. The UAZ 31514-10 and UAZ 31608 with the domestic turbodiesel ZMZ-514, UAZ 315123 with the Polish 4ST90 Andria and UAZ 315195 with the ZMZ-409 gasoline engine were provided to our disposal. The process of laying the test route and a demonstration of the capabilities of the car on the slopes of the forest, covered with a 50-70-centimeter layer of snow, made a strong impression. Still, because at the wheel, the head of the factory testing center with enormous experience of off -road driving and madly in love with his native UAZ. The outer ease turned out to be deceiving - from the first meters of an independent trip you understand that these cars are created for real men. Managing them is not easy, but all the more pleasure. Fluffy branches of pines over small meadows, sparkling in the sun, virgin snow attracted to themselves, as if offering to relax at the hot fire and enjoy the surrounding beauty under the cup ... tea and thread of a fragrant barbecue. But work is in the first place.
 
Having robbed the slopes of the nearest hills, we move to the route of resource tests - along the rifs along the edge of a huge field. This is already a plain, but also off -road, with dense night snow. The fact that tests are held here are testified by deep hard ruts. The highway is heavy and insidious, does not forgive hotness and fuss. An experienced test driver rarely lips the car out of the rut, but, having made such a mistake, in most cases it selects on its own, without even leaving the cabin, by skillful downloading of the car without a wheel slipping. Inexperienced - at best, is forced to work with a shovel.
 
We complete testing by comparing the dynamic qualities of cars already at dusk on a frozen, but dry asphalt highway Ulyanovsk-Sizran. It would be incorrect to conduct your own measurements on public road - you need a landfill and plus temperature. Therefore, relying on the results presented by factory specialists (see table), and analyzing our own sensations, we formulate a preliminary opinion about the pros and cons of the presented engines. To understand the difference in full, you need to travel on cars longer and in various conditions - as professionals say, live with a car.
 
Having abstracted from the differences of machines in terms of noise, smoothness, the presence or absence of a power steering, we will focus on the capabilities of the engines.
 
Where is he, ideal?
The pros and cons of each of the engines are given in business cards - here we will express subjective sensations. In short, who to choose what engine.
Those who do not trust new -fangled technical solutions, who are used to doing without car services and, in addition, are not often chosen on even asphalt, should pay attention to Andria. The atmospheric diesel proven for years promises to behave quite predictably, since it is unpretentious to fuel and maintenance. On off -road, he will not require special skill from the driver and forgive him a number of errors in working with the gas pedal. But on the UAZ 315123 highway with its four -speed box will not show miracles - it is better not to think about speed and economy.
 
Adherents of progress, sometimes moving from asphalt to the ground, of course, will look closely at cars with ZMZ-514. However, we remind - the motor, let's say, is young and inexperienced: no one knows how he will behave in operation. But if such difficulties do not bother you, then the reward will be good dynamics and high fuel economy in traveling in highways. In off -road exercises, he is still inferior to the Pole.
Those who are afraid of winter problems with diesel fuel and, besides, do not expect to constantly ride on the road, remains to rely on the power and reliability of the ZMZ-409 of the ZALZH engine. The engine is serial, the bulk of children's problems is solved, and the dynamics of the machine at the level. Of the shortcomings, we note, of course, the worst fuel economy - both the consumption is higher and gasoline is more expensive than diesel fuel.
 
It remains to add that the retail prices of diesel UAZs today are: 31512 with Andria - 195 thousand rubles, 315143 with the same engine - 200 thousand per car 31514 with ZMZ -514 will have to pay 200 thousand, but Simbir UAZ 31608 With the Volga diesel engine will cost 280 thousand rubles.
Now let's down the line. The fact of the appearance of diesel engines on the UAZ conveyor guarantees machines to increase demand in the domestic market. Moreover, all -frustrations with diesel engines fulfilling modern requirements for the toxicity of the exhaust will expand the geography of export supplies. After all, they show interest in Ulyanovsk machines in countries such as Angola, Afghanistan, Iran, Kenya and Macedonia.
 
Andria 4st90
It is produced by the Polish plant of the same name. A direct descendant of the eminent English perkins.
Working volume - 2, 417 l; The diameter of the cylnar x piston stroke - 90x95 mm; Compression degree -26.
The mass assembly with the card and clutch - 258 kg.
Badddual (atmospheric), maximum power - 63.5 kW/86 liters. With. at 4000 rpm; The maximum torque is 183 N.M at 1800 rpm.
The characteristic of the torque is convenient for off -road driving. Unpretentious.
The worst in comparison with ZMZ-514 acceleration dynamics and fuel economy.
 
ZMZ-514
Turgodiesel of the Zavolzhsky Motor Plant.
Working volume - 2.24 liters; The diameter of the cylinder x the piston stroke - 87x94 mm; The degree of compression is 19.5.
Mass - 225 kg.
The maximum power without intermediate cooling of the bent air is 72 kW/98 liters. With. at 4200 rpm; Maximum torque - 216 NM at 2500 rpm.
Moderate appetite with the best dynamics than that of Andoria.
Inferior to the Pole in traction.
ZMZ-4092.10
The gasoline engine of the Zavolzhsky engine factory.
Fuel - AI -93 gasoline.
Working volume - 2.69 l; The diameter of the cylinder x the piston stroke - 95.5x94 mm; The degree of compression is 9.0.
Mass - 195 kg.
The maximum power is 94.1 kW/128 liters. With. at 4400 rpm; Maximum torque - 217 NM at 2500 rpm.
With him, UAZI is faster and more dynamic.
Relatively high fuel costs and not optimal character for the passage.
