Sequential CNG Kit Fitting

A Sequential CNG Kit, often referred to as a Sequential Injection CNG Kit, is a type of CNG (Compressed Natural Gas) conversion kit designed for vehicles to run on compressed natural gas as an alternative fuel source. The sequential aspect of this kit refers to the way it injects CNG into the engine combustion chambers in a precise and controlled manner. This sequential injection system is more advanced and efficient compared to older non-sequential or mixer-based CNG systems.

CNG Storage Tanks: These are high-pressure cylinders or tanks that store compressed natural gas, just like in any CNG conversion kit.

CNG Regulator: A regulator is used to reduce the high-pressure CNG from the storage tanks to a lower pressure suitable for the engine.

Fuel Injectors: In a Sequential CNG Kit, the system includes CNG fuel injectors that are designed to inject CNG directly into each cylinder combustion chamber in a precise and timed sequence. This is similar to how gasoline or diesel fuel injectors operate.

ECU (Engine Control Unit): The heart of a Sequential CNG Kit is the electronic control unit or ECU. It monitors various engine parameters and controls the timing and duration of CNG injection for each cylinder. This ensures that the CNG is delivered accurately based on the engine needs.

Sensors: The ECU relies on various sensors, including those for engine speed, throttle position, and oxygen levels in the exhaust, to optimize CNG injection and combustion.

Wiring and Connectors: Wiring harnesses and connectors are used to connect the ECU, injectors, and sensors to the vehicle electrical system.

Safety Features: Like all CNG kits, Sequential CNG Kits incorporate safety features such as pressure relief devices, shut-off valves, and leak detection systems to ensure safe operation.

The main advantage of a Sequential CNG Kit is its ability to precisely control the amount of CNG injected into each cylinder, optimizing combustion efficiency and performance. This leads to better fuel economy, reduced emissions, and improved engine reliability compared to older mixer-based systems.

However, it is important to note that the installation of a Sequential CNG Kit should be performed by certified professionals who are experienced in CNG conversions. Additionally, the availability of CNG refueling infrastructure in your area and the compatibility of your vehicle with a Sequential CNG Kit are important factors to consider before converting your car to run on CNG.
