Humanity is progressing further in today’s age of sustainability. However, sustainable means usually come with an increased cost. Yet CNG kits defy this conception. CNG conversion kits are far more economical and eco-friendly than conventional fossil fuels. This walkthrough guide explains the CNG kit, installation, benefits and potential drawbacks.
CNG Conversion Kit
A CNG Kit is a conversion system designed to tweak petrol-based vehicles to run on CNG. The kit encompasses components designed to safely store, regulate, and inject CNG into the engine.
Key Components of a CNG Kit:
- CNG Cylinder with Valve, Vapor Bag & Bracket: Stores compressed natural gas.
- Pressure Regulator & Gauge: Controls and monitors the gas pressure delivered to the engine.
- High-pressure Gas Tube: Connects the cylinder to the regulator.
- Petrol Solenoid Valve with MO Switch: Stops petrol flow when using CNG.
- Gas Air Mixer/Injection System: Blends gas and air for combustion.
- Ignition Advance Processor: Enhances engine performance using CNG.
- Control Module: Switches between petrol and CNG.
- NRV in Petrol Return Line: Prevents petrol backflow.
Types of CNG Kits
Two major types of CNG car kits exist in the Indian automotive market:
| Venturi CNG Kits | Sequential CNG Kits |
| Used for carburettor vehicles | Only used in fuel-injected vehicles |
| Budget friendly | Higher pricing |
| Lower fuel efficiency | Higher fuel efficiency |
| Delivers a predetermined amount of fuel into the engine | Fuel flow is determined by the Electronic Control Unit (ECU). |
| Frequent cleaning and maintenance | Less maintenance |
| Slower acceleration | Smoother acceleration Higher long-run performance |
Authorised CNG kit prices for sequential kits tend to be higher, but they fit a modern car better with two variants:
- Closed loop system
- Open loop system
