AUDI AG is a German company that produces cars under the Audi brand. It is part of the Volkswagen Group. The name Audi is based on a Latin translation of the surname of the founder August Horch, which could mean "listen!" in German. Audi is headquartered in Ingolstadt, Germany. On July 16, 1909, the automotive pioneer August Horch founded August Horch Automobilwerke GmbH in Germany. A short time later, he changed the name of the company after the Latin translation of his surname, so it became Audi Automobilwerke. P>
Daimler-Benz AG acquired Auto Union GmbH on April 24, 1958. From then until the end of 1965, Auto Union was a wholly-owned subsidiary of the Daimler Group based in Stuttgart. Volkswagenwerk AG acquired the majority of the shares of Auto Union GmbH in December 1964, and Audi became a subsidiary of VW since 1966. p>
In January 1985, Audi NSU Auto Union AG was renamed AUDI AG. At the same time, the company moved its headquarters to Ingolstadt. From this moment, the cars in front and the company had the same name. P>
The range of cars with CNG Compressed Natural Gas that offers the audi brand in United States is extended with the possibility of adapting retrofit: p>
A CNG compressed natural gas car usually maintains the same gasoline system as the traditional version incorporating CNG compressed natural gas equipment.
1.- Safety valve Activated when the internal pressure of the CNG reaches 300 bar allowing a pressure relief of the unit
2.- Storage Tank Compressed Natural Gas is used at 200 bar pressure in cars
3.- Electronic Control Unit Controls the injection of fuel into the engine based on the parameters previously installed in the memory of the control unit
4.- Sequential Injectors Normally they are injectors dedicated to natural gas and they are in charge of introducing the compressed natural gas in the chamber of combustion of the engine
5.- Low Pressure Pipeline
6.- Pressure Regulator Until it reaches the CNG by high pressure pipes (200 -10 bar), it is reduced pressure and exits in low pressure pipes (2-3 bar). To maintain the gas conditions and avoid a sudden change in temperature Reducer due to pressure reduction, the reducer is connected to the vehicle's cooling system. It has a safety valve that prevents the low pressure from increasing above 2.25 times the maximum operating pressure.
7.- Pressure Sensor
8.- Lambda probe
9.- High Pressure Pipe
10.- Charge Valve It is the quick connector for charging the system and is directly connected to the reservoir / s
Compressed Natural Gas / CNG is invoiced in KG, contrary to the liters of traditional fuel
The network of service stations with compressed natural gas / CNG is being developed although it is scarce in the UK at present p>
El Gobierno de España, a través del Plan Movalt incentiva la adquisición de vehículos con gas natural comprimido gnc, así mismo existen muchas ventajas a nivel local como reducciones de Impuesto de Matriculaciones, IVTM,...
Being a cleaner system, catalytic converters, filters, "adblues" are eliminated, which reduces the possibility of mechanical breakdowns. Thus, for example, the service life of the oil increases with what it means for motor care
The first cities begin to limit the access of diesel vehicles, in their restrictive regulations vehicles with CNG have access advantages
Today there is a wide range of car makers offering lpg versions for their cars in Europe , just for one simple reason:
There are more than 15 million of cars running on lpg on european streets not a small market for car producers
Indicates that the model has a guarantee / insurance from the manufacturer or importer
Indicates that the model is adaptable to consume CNG and has warranty / insurance from the equipment installer
Indicates that the model is offered with guarantee / insurance from the manufacturer or importer in the indicated country
A good autonomy of 700 km, a low cost of fuel and a high suitability for daily use: when the characteristics and advantages of the Audi A4 g-tron are observed, the question inevitably arises: why do not they drive many? more natural gas cars? The answer is to provide a long-term test: for a whole year, the compressed natural gas Audi should show what it can do. P>
The basic data of the test: the two-liter combustion engine of the g-tron generates 125 kW / 170 hp at 4,450 rpm, the maximum torque of 270 Newtons is at 1650 rpm. In the test circuit of Audi in Ingolstadt has a maximum speed of 223 km / h, with 8.5 seconds from 0 to 100 km / h. Its consumption (gas) is Audi with 4.2 kilos per 100 kilometers. These numbers already show: the Avant is a normal car, compared to the pure gasoline engine with the same engine, loses only a small percentage of power and torque. Another difference: the trunk is a little smaller due to the gas tanks located below, the g-tron reaches 415 instead of 505 liters. There is also no space for a spare wheel. P>
Otherwise, everything is Audi. Fine workmanship, pleasant materials, an extremely successful chassis, even without electronic adjustment options, which offers combined sportsmanship and comfort under one roof. The mode of operation is relatively simple, the MMI rotary knob with the function keys around it can be operated virtually blindly after a brief acclimatization. There is no digital cab for the A4, but the analog instruments are clearly displayed. And in the central part the most important information is displayed, such as the Navi map, the consumption, the list of telephone contacts or the radio and adjust the climate control. P>
When it is completely full, the g-tron has 19 kilos of natural gas and 25 liters of gasoline. How far can you go with this amount of fuel? In the first half of the test, the values were set at 370 kilometers with compressed natural gas and 330 kilometers with gasoline after driving 3,600 kilometers. The average consumption meter indicates a value of 5.4 kilos per 100 kilometers.
Another detail: Because an engine optimized for compressed natural gas when running on gasoline consumes a little more than a pure gasoline engine, it should in principle be as economical as possible on the road, and operate only with CNG. In the absence of an extensive network of recharging points, you must be lucky to have one in your route. By way of comparison: It takes up to four minutes for a gas pump to push up to 19 kilos in the tanks. It is not a drama, but it is much longer than liquid fuels. And more often, after all, after a maximum of 350 kilometers it must be filled. And this turns out to be a long-term obstacle from time to time. P>
