In September 2021, the Indian government had specific rules and regulations regarding CNG cylinder testing and installation in CNG vehicles to ensure safety and compliance with standards. Please keep in mind that regulations may have evolved since then, so it’s important to verify the most current information from official government sources. Here are some key points related to CNG cylinder testing and installation
Open Loop System contains advanced timing Sensor / Emulator MPFI. The system is pretty basic and it needs regular adjustments if you need the best performance out of it. You will also need to check the Engine lamp due to the lambda error. Open-loop systems don’t calculate Lambda 02 reading but keep the gas flowing according to the requirements.
Closed-Loop System comes with Lambda controller ECU / Stepper Motor / MPFI Emulator. This system has complete automatic gas regulation and it also depends on what the car engine requires. Apart from that, it emulates the Lambda 02 reading to the Main Car ECU to prevent engine check.
Available for 3,4,6 & 8 Cylinder engines. CNG Sequential Kits – latest technology product that gives a performance at par with petrol cars. Instead of the GAS-AIR mixer as used in Conventional Kits, Sequential Kit is equipped with GAS Injectors similar to Petrol injectors to Inject a calculated amount of GAS into the engine.
Direct Injection Kit is designed for 3,4,6 and 8-cylinder engines. Support All Direct Injection Engines Like T-GDI / FSI /EcoBoost / TSI, etc. The Direct Injection CNG Kits allows adding a maximum of 20% to 30% Gasoline with natural gas for certain cars. It has a minimum amount of gasoline to add with a range of 2-3%. It is available with a Single-stage reducer, adapted to support all engines with direct fuel
In the realm of cutting-edge technology and innovation, Science and Technology Ventures Limited proudly stands as the pioneer in setting up the very first periodic CNG Cylinder testing facility in Rajasthan, India. Approved and accredited by the Petroleum and Explosives Safety Organization (PESO), Government of India, our testing facility is equipped with state-of-the-art, world-class high-tech instruments. We take immense pride in ensuring the safety and environmental friendliness of CNG as a fuel source.
The use of Compressed Natural Gas (CNG) as a fuel source is not only economical but also a sustainable choice for the environment. However, with great power comes great responsibility, and safety regulations and standards are paramount when it comes to manufacturing and utilizing CNG onboard cylinders.

Retesting of CNG cylinders is an integral part of these standardized norms and procedures that must be diligently followed by all users of CNG-fuelled vehicles. Our dedication to safety extends to the filling stations as well. We adhere strictly to the guidelines laid out by the Petroleum and Explosives Safety Organization of India, ensuring that only retested cylinders are filled, guaranteeing the safety of vehicle owners, passengers, and public property alike.
Apart from our commitment to CNG conversion, M/s Science and Technology Ventures Limited has taken yet another leap forward by establishing the inaugural periodic CNG Cylinder testing unit in Rajasthan. This facility is equipped with cutting-edge, world-class high-tech instruments that ensure precision and accuracy in every test conducted.
Hydrostatic Testing is a non-destructive test procedure that plays a pivotal role in ensuring the safety and quality of CNG cylinders. This method is employed to examine cylinders for potential leaks, structural flaws, durability issues, and corrosion. It primarily focuses on assessing the structural integrity of the cylinders, ensuring they are fit for service.
The Hydrostatic Testing process involves enclosing a CNG cylinder, filled with water, inside a specialized test jacket that is also filled with water. Pressure is then applied internally to the cylinder, causing it to expand. During this expansion, the amount of water displaced by the cylinder is carefully measured. This measurement provides critical data about the total and permanent volumetric expansions of the cylinder while under pressure and after the pressure has been released.
In addition to the quantitative measurements, an external and internal visual inspection of the cylinder is conducted. This visual assessment ensures that no surface imperfections or irregularities go unnoticed, further enhancing the overall safety and quality of the CNG cylinder.
