The operation of such an engine (DI, GDI, etc.) on LPG fuel looks like this: a small amount of petrol is fed over the entire range of its operation. Then the LPG controller turns off the petrol injectors and the LPG fuel is injected into the intake manifold through the gas injectors. The gas together with the air goes to the cylinder and completes the demand for fuel. Petrol injectors are constantly protected. The minimum and maximum dose of gas depends on the needs of the engine, its operating parameters and mechanical elements of the gas system (mainly injectors). In Zenit Direct Box installation, the petrol dosing range is set smoothly. The amount of additionally injected petrol is so small that it does not have a significant effect for driving economy.
ZENIT Direct Box allows millions of Poles to be more ecological and economical. The cost of driving a petrol-powered car and a gas-powered car in the case of ZENIT Direct Box with LPG fuel injection is much lower than in the case of petrol alone. We show examples of fuel consumption for 2 vehicles: Skoda Octavia 1.2 TSI and Skoda Superb 1.8 TSI. Traveling with vehicles powered by Zenit Direct Box gas installation is also more ecological.
You can definitely say that, because the use of LPG fuel, considered as an ecological alternative fuel, reduces the level of car exhaust emissions in relation to petrol combustion. Enterprises, as well as any driver who wants to contribute to improve air quality and the environment, can choose to drive on LPG with our installation dedicated to cars with engines with direct petrol injection. When running on gas, compared to petrol, the car emits approximately: 60% less carbon monoxide, 10% less carbon dioxide, and also 50% less hydrocarbons and nitrogen oxides. Installation of autogas LPG and CNG systems definitely has a positive effect on the car exhaust emission values. That is why Zenit Direct Box installation is very often chosen by drivers who want to live in the spirit of ECO.
Especially in Poland, where considered to be green electricity, unfortunately, is produced from coal power plants, which is not ecological. On the other hand, LPG fuel is, among others, a by-product of oil extraction, which means that it does not require an additional environmentally negative production process. As a by-product, it is a clean fuel. In Poland, LPG can be refueled at every large station and additionally at smaller ones that offer only autogas. Such an extensive infrastructure makes the access to this ECO fuel at your fingertips. What is important, the network of workshops specializing in the installation of gas systems is also very wide. ZENIT Direct Box is a ready answer to the already possessed resources of our country.
The Direct Box model is based on a certified 32-bit processor from NXP. The processor is commonly chosen by car manufacturers. The certificate is awarded to companies producing automotive components and is a proof of the highest quality. It was designed by experienced founders of International Automotive Task Force (IATF), which brings together companies such as BMW Group, Daimler, Fiat, General Motors, or Volkswagen and industry organizations. The awarded certificate guarantees compliance the strictest standards of the largest automotive concerns and the certainty that the processor in Zenit Direct Box will work perfectly in each car and will cooperate with the vehicle installations. Zenit Direct Box was created on a six-layer printed circuit board, and thanks to electromagnetic interference shielding, it works stably. Lacquering the circuit board with a special varnish provides maximum moisture resistance. Zenit Direct Box is the most thoroughly protected controller in its category.
By choosing Zenit Direct Box, you bet on a proven solution and ensure stable savings.
Zenit Direct Box controller is available in 2 versions: 4 and 6 cylinders. It has a built-in OBD module and a petrol pressure emulator. This is a solution tailored to the development of the broadly understood automotive industry. Zenit Direct Box installation is the result of the meticulous work of our R&D department, which used the knowledge and experience gained over the years. This solution is a response to the real needs of modern drivers.
WHAT MAKES THE DIRECT BOX MODEL DIFFERENT?
- NEW DESIGN OF RGB SWITCH
- UNIVERSAL SHAPE OF HOUSING, WHICH IS IDEAL FOR INSTALLATION (KNOWN FROM THE PREMIUM MODEL - BLACK BOX)
- PROVEN WIRING HARNESS FROM THE ZENIT CONTROLLER FAMILY
- homologated minimum operation temperature: - 20⁰C
- homologated maximum operation temperature: + 120⁰C
- supply voltage: 10-16V
- maximum power consumption: 10A/4 cyl, 15A/6 cyl
Hardware - Zenit Direct Box supports the same OBD protocols as Black Box:
The LPG Direct Box controller is 100% immune to any electromagnetic interference. This is confirmed by the approval obtained in accordance with Regulation 10 of the UN ECE. The document says about the electromagnetic compatibility of electrical and electronic devices used in cars.
In some configurations of Zenit Direct Box control panel, we use an additional, external emulator of petrol injectors. The emulator which is homologated together with the control panel is available in two types: 4-cylinder (designation 4RL001) and 6-cylinder (designation 6RL001). We have fitted the emulator into the compact housing of Zenit Blue Box LIGHT, ensuring a minimum of space under the hood.
Does Zenit Direct Box controller also support engine codes and car models that Zenit Direct supported? Yes, all configurations developed by us over the years have been transferred to the new Direct Box.
Will the existing Direct be updated? It will have technical support, however, it will not be updated.
What is the process of updating the Zenit Direct Box software? The installer receives information about the availability of new software for the control panel (firmware) after starting the program and decides whether he wants to update it (recommended). The new software will be available on our website.
What is the configuration update process like? You select the configuration of Zenit Direct Box installation for a specific engine code in the program from the drop-down list. The configuration database in the software can be updated in two ways: manually and automatically (after selecting the option in the program).
Can I open Zenit Direct Box with a program dedicated to Zenit Direct installation? We have created a new dedicated Zenit Direct Box program. Its icon differs from the already known icon of the Zenit Box program only in color - it is gray, just like the Direct Box housing.
What interfaces does the Direct Box model connect to? With all AG Centrum interfaces, i.e. RS32, USB and Bluetooth.
What switches does the Direct Box model work with? With a switch dedicated to the Blue Box and Black Box models (including the RGB switch).
