As the most suitable option was considered a small four-door body sedan, 1.5-liter engine and independent front and rear suspension, which at that time was attended by no means all machines. 1962: Dealers receive cars for their salons. Run the car into production by 1961 and at the same time submit it at the Frankfurt Motor Show was virtually impossible: simply not enough time. Pressured sales in a matter of urgency to the exhibition has been produced several prototypes, intended to attract future clients. Rate has been made and largely justified. During the exhibition, and for the next several weeks, was made about 20.000 orders for the BMW-1500 “! Try to imagine situation in which the company was the release in 1962 only 2000 cars! In general, the production of the “1500” for all time of its existence on the line amounted to 23.000 copies. This was the beginning of the climb to the top of the automotive industry.
In the midst of the production model “1500” small engineering firms have begun to refine the car and increase the capacity of the motor, which, naturally, could not possibly appeal to the leadership of bmw. Response was the release of the model 1800 with 1.8-liter engine. Moreover, later a version 1800 ti , corresponded to the car class” Gran Turismo “and accelerate to 186 km / h. Externally, it is not very different from the basic version, but, nevertheless, was a worthy addition to the already family.
Turbocharger (TCR) – a separate unit which forcibly supplies air to the engine cylinders, thus improving its treatment and improves the quality of the working mixture. One part of the tcr is associated with the engine and exhaust system driven by the energy of the exhaust gases of the engine, while the second part of the intake system. tcr is divided into two types: the tcr with a gas-driven and mechanical. Gas turbocharger can be air cooled and the cooling fluid. Mechanical blowers, there are several types: G-type compressor – G60 on cars vw Corrado and Passat, the compressor Comprex on cars Mazda 626, a compressor Ruts on American-made Buick automobiles and others. Just found the centrifugal blowers driven.
But most cars are equipped with turbines that use the energy of the exhaust gases. All modern cars are equipped with turbo which allows to increase power engine at 20-35% of the engine, turbocharged, has a higher torque at medium and high revs, which makes the car more dynamic and cost effective motion. But when braking motor vehicle stops slower due to a reduced degree of compression in the cylinders. Turbine begins to operate efficiently on diesel cars 2200-2500 rpm, the gasoline 2800 – 3500 rpm. Period of engine speed from idle before turning the turbine is called turbo-yama. Modern turbine control system to minimize the effect of turbo-pit.
Indicator of the efficiency of the turbine is the boost pressure, which in Diesel engines typically reaches up to 0.6-0.7 bar, and gasoline from 0.6-1.0 bar. Advantages of the engine with turbocharger: Value 'weight / power' in turbocharged engine is higher than that of the classical, turbocharged less cumbersome than the usual same power, torque curve with a turbine engine can be better adapted to the specific operating conditions. In this case, for example, the driver of a heavy truck will have a much less likely to shift gears on a mountain road, and self-driving would be more lenient, with a turbine engine is almost immune to significant change of height, whereas the classic engine loses power, turbocharged improves the combustion of fuel, it also helps to reduce exhaust gases from the turbine engine works more stable than the classical counterpart of the same capacity, with more power and economy. If take into account all these factors it becomes clear that it's easier just to buy a car with a turbine, what to do rework. Intake – when the piston down, air (diesel engine) or a mixture of fuel and air (gasoline engine) passes through the open intake valve. Compression – a compression of combustible mass. Extension – a mixture of air and fuel is ignited by spark (gasoline engine), diesel fuel is injected under the pressure and inflammation occurs randomly. Issue – When the piston upward, produced exhaust gases injected air passes through a pipe through the intercooler (internal air cooler) intake collector, getting into the combustion chamber. Intercooler is used to in the hottest time of year, the amount of air entering the intake manifold volume was equal to the amount of air in the cold season. Quality burnable fuel depends on the percentage of fuel-air mixture and determines the state of the engine exhaust. Diesel pump (injection pump) has a turbo equalizer, which supplies fuel relative to entering the enclosure combustion air. A similar correction occurs in the injection systems.
Began a propaganda demonstration and verbal battle for the honorary title of inventor of cars. This was concerned not only individuals but also of the state. Some of them were close to the truth, but the scientific and technological world is not found them. On several of these authors should be discussed separately because, although they remained in the shadows, their contribution to the improvement of the powerful car. Thus, the orbit of the transport boom suddenly – unexpectedly came Siegfried Marcus. He was the officer in engineering had a side relationship. But his ambition is not so, as a state, has taken some time over the mountain of common sense. Why it suddenly such an empire as the Austro-Hungary, did not have a creator? St rulers found clue: Marcus was invented horse cart.
Interested parties have created a myth around it, ostensibly Self-propelled design ready for testing. However, the second official attempt was successful: in 1887 he designed the cart, which is so-syak moved. Another official, now an American, George Selden, unlike Marcus with greater impudence and stubbornness to prove its right to the discoverer. Working in notary's office, and so, knowing full well the laws, in 1879 he filed a patent application, in which skilled and outlined his proposals. Read it – before you present technical breakthrough! So, when sa started produce cars, he sued the manufacturers. After that, several companies tied to the author of a long nasty red tape until 1910. Meanwhile, the court demanded that Selden made the same machine for their project.
