Declaration of the origin of Zenit

Dear friends. Quite a long time among users of Zenit was common misperception about the country of origin, many of you believed that it was a Polish system. This view was due in part to our lack of precise positioning, but mostly misinformation coming from our competitors and well-wishers contributing to confusion, and argued that the system is not Italian, and Polish.
Our word, that the system is actually made in Italy, and only the brand owner is the company geographically located in Poland, the majority still did not believe. Mistakenly did not share their country of origin of country ownership marks.
Unfortunately, our one voice against the crowd was powerless. We decided to put an end to this matter.
We company "EFKAS", "KOSTA GAS", the official distributor of AG Centrum, with all the authority declare- the system of 4-th generation Zenit (JZ-2005 / 4) of the company AUTO-GAZ CENTRUM, made in Italy by Autronic Srl.

Fundamentals GCE

What advantages in gas fuel compared to gasoline?
Not only the price of gas, because of which GCE is usually installed.

In the transition to the gaseous fuel is its complexity. For example, the density of natural methane is a thousand times lower than that of gasoline.Therefore, if the car fill with methane at atmospheric pressure, then for an equal amount of gasoline fuel tank will need to 1000 times more. In order not to carry a huge trailer with fuel necessary to increase the density of the gas. This can be achieved by compression of methane to 20 ... 25 MPa (200 ... 250 atmospheres).For storage in this state used special containers that are installed in cars.

Natural gas, methane is able to dramatically reduce the volume (600 times) at its low-temperature.Such liquid gas can be transported in special "tanks in" at a pressure of not more than 6 atmospheres (pressure of water in the faucet). There are many technical developments and patents to implement such technology for liquid methane.Throughout the world, has already produced and consumed many millions of tons of chilled (up to a temperature of about -120 ° C) of methane. Major producers, Indonesia, Algeria, Libya, USA, Norway, etc.For transportation of used tankers CNG displacement of up to 120 000 tons (Japan), products of complete combustion of methane is harmless substance - carbon dioxide and water. That is why we feel comfortable in our kitchens, where sometimes the whole day burning gas (methane) burner.

LPG - synthetic fuel. It is refined from crude oil and condensed oil associated gases. For this mixture remained liquid, its stored and transported under pressure of 1,6 MPa (16 atmospheres). Compressed gas equipment for liquefied LPG some what simpler.The process of refueling at gas stations is simple and very similar to a gas station with gasoline.

The properties of liquefied LPG is not very different from compressed natural gas. The same high octane number, the same good environmental and operational performance. There is a liquefied LPG advantage over CNG - 225 liters of fuel sufficient to run about 500 kilometers, and methane, are placed in the eight cylinders - in half. Liquefied gas works half the cars than on highly compressed. LPG obtained in 20 ...25 times less than that of natural gas.

Generations gas systems

In our market, using different types of work on the principle of gas systems. For their classification, the term "generation". The difference in the complete set of GCE generations generally refers to elements of gas supply and control system, located in the engine compartment. Placed outside the compartment system components - for fueling device, gas pipes, tank and its equipment - are identical for all generations.

The first generation of GCE. Systems with a vacuum control and a mechanical dispenser gas, which is set on the gasoline carburetor and simple injection cars. In the first generation GCE used as vacuum, and electronic gas reducer. Without a lambda probe.This is a traditional unit with mixing gas. The fundamental difference between the vacuum of the electronic gear is to stop element handling the camera:
a vacuum this function is performed by vacuum diaphragm to which is supplied from the vacuum intake manifold
engine is running - there is a vacuum - gearbox open
engine is stopped - there is no vacuum - pressure regulator is closed.

Second generation GCE. Mechanical systems, complemented by an electronic metering device operating on the basis of feedback from the oxygen sensor.They are mounted on vehicles equipped with fuel-injected engine, with Lambda sensor and catalytic converter and catalytic converters ( "catalyst"). This is a traditional unit with mixing gas, additionally equipped with a gas divider.
To maintain the proper composition of the gas-air mixture, the lambda-controller uses the signal from full-time Lambda probe vehicles, as well as signal throttle position and engine speed sensor to optimize air / fuel mixture at the transient conditions of the engine.
System 2-generation ensures the maintenance of environmental requirements of Euro 1. Some of Lambda control, with two adjustment (at idle and at speed) support the environmental requirements of Euro 2.
Systems of first and second generations have a number of shortcomings, and do not meet the currently valid standards of the UNECE.Toxicity of exhaust gases from vehicles equipped with such systems, usually located at the level of Euro-1 norms, which operated in Europe until 1996, and only in some cases closer to Euro-2 standards.In this connection, gas equipment manufacturers have developed systems of the third and fourth generations, who are becoming increasingly common.

The third generation of GCE. Here is the individual gas cylinders in separate metering device (gas injection), which has a flat management portion of gas, which is controlled by an electronic unit.Gas is fed into the intake manifold by means of mechanical injectors, which are opened by excess pressure in the pipeline gas supply.

System 3 generations do not use the computing power and fuel cards laid in regular gasoline controllers, they simply work in "parallel" mode, ie, create their own fuel cards.The reaction rate on the adjustment of the mixture with 3 generations of systems is not high and is due to the speed of the stepper feeders - the distributor.Therefore, with the advent of the environmental requirements of Euro-3 and the onboard diagnostics system 2 generations of OBD II and EOBD, demand for gas system 3 generations down, and given their relatively high cost and the emergence of systems of 4 generations has practically vanished.
Installing GCE third generation injection vehicles differs in that instead of gas valve to cut off the petrol injector emulator is used. When the gas is supplied, the emulator mimics the work of the petrol injectors, to full-time computer is not turned into emergency mode.For the same reason, you need to install an emulator of the lambda probe.

The fourth generation of GCE. This is a system with distributed synchronized gas injection.This is the latest and the best solutions known today in Eastern Europe: a separate control supply of gas (gas jets) for each cylinder, which are managed more sophisticated electronic unit.As in the previous generation, gas equipment (GCE) 4 generation using gas jets, which are installed on the collector directly from the intake valve of each cylinder

The fifth generation GCE. Intended for use in any fuel-injection vehicles and is compatible with the environmental requirements of Euro 3 and Euro-4 as well as systems on-board diagnostics OBD II, OBD III and EOBD.

Unlike systems 4 generation, gas generation system 5 goes to the cylinders in the liquid phase.To this end, the cylinder is "gas pump, which circulates the liquid phase of gas from the cylinder through the ramp of gas jets with valve back pressure back into the tank.5-generation systems using the processing power and fuel cards, laid out in full-time controller, a / m, and make only the necessary adjustments to adapt the system to the gas gasoline fuel map.5 generations characterized by the presence of separate electromagnetic injector injection in each cylinder that is completely analogous to the gasoline system. Phase and dosage of injection determines the full-time controller and gasoline / m. An important advantage of systems 3.4 and 5 generation is automatic switching from gas fuel to gasoline.By the 5-generation systems mainly include the lack of power losses and the absence of increased gas consumption, as well as the ability to run the engine at any gas at low temperatures, as well as the need to vaporize the gas had disappeared prior to supply to the engine.The disadvantages of the system include its high sensitivity to the dirty gas, low maintainability and high complexity. Three of the lack of practically negated all its advantages in operating conditions in the countries of eastern Europe and Russia.
