What Is a CNG Advancer and Why Your Vehicle Might Need One10 September 2025
With the rising fuel prices and growing environmental concerns, CNG (Compressed Natural Gas) has become a preferred alternative fuel for thousands of Indian car owners. While installing a CNG kit for cars is a smart move, many overlook a critical component that significantly impacts performance, the CNG Advancer.
In this blog, we’ll explore what a CNG Advancer is, how it works, its benefits, and why choosing a genuine one from MIJO Auto Gas, a best CNG kit manufacturer of India, can make all the difference.
What Is a CNG Advancer?
A CNG Advancer is a crucial component in a sequential CNG kit. It helps in adjusting the ignition timing of the vehicle’s engine to suit the combustion characteristics of CNG, which differs from petrol.
Unlike petrol, CNG has a higher ignition temperature. This means the fuel needs to be ignited slightly earlier to ensure smooth combustion. The CNG Advancer does exactly this—by advancing the ignition timing, it ensures your vehicle performs efficiently on CNG without knocking, power lag, or poor pickup.
How Does a CNG Advancer Work?
The CNG Advancer works by intercepting signals from the vehicle’s sensors, especially the crankshaft or camshaft position sensors. It then advances the ignition timing during CNG mode to compensate for CNG’s slower combustion rate.
In sequential CNG kits, the CNG Advancer integrates with the Electronic Control Unit (ECU) and adapts dynamically based on driving conditions. This allows for smoother power delivery, improved throttle response, and better mileage.
MIJO Auto Gas’s advanced sequential CNG kits come pre-calibrated with ignition timing optimization, offering the same benefits as a standalone CNG Advancer without requiring additional components. These kits are engineered for Indian driving conditions and are compatible with a wide range of vehicles from hatchbacks to commercial 3-wheelers.
Benefits of CNG Advancer
Choosing the right CNG Advancer offers multiple advantages:
- Improved Mileage: Correct timing results in more complete combustion, giving you more kilometers per kilogram of CNG.
- Better Acceleration: Avoids power loss commonly experienced in petrol-to-CNG converted cars.
- Longer Engine Life: Reduces engine knocking and harsh vibrations.
- Smooth Engine Performance: Particularly useful in city driving with frequent stop-start conditions.
- BS6 Compatibility: Designed to work with modern BS6 engines and electronics.
When paired with a high-quality system like those from MIJO Auto Gas, the CNG Advancer becomes a game-changer for performance-conscious drivers.
CNG Advancer Cost in India
The CNG Advancer cost in India can range anywhere between ₹1,500 to ₹4,000, depending on the vehicle type, kit compatibility, and brand.
MIJO’s CNG kits are built to include factory-calibrated ignition timing adjustments—delivering the benefits of a timing advancer with every installation.
Beware of Fake CNG Components
With the increasing demand for CNG kits and parts, counterfeit products are flooding the market. Fake CNG Advancers may be cheaper, but they can damage your ECU, reduce mileage, and even void your warranty.
How to avoid fake CNG components:
- Always purchase from authorized dealers like MIJO Auto Gas.
- Check for ISO or ECE certifications.
- Verify part numbers and packaging.
- Never install parts without proper mechanic validation.
MIJO’s products are certified under ISO 15500, ECE R110, and tested in-house for Indian conditions making them a trustworthy choice.
5 Signs You Need a CNG Advancer for Your Car
Not sure if your vehicle needs a CNG Advancer? Look out for these signs:
- Loss of Power: Car feels sluggish, especially during acceleration.
- Engine Knocking: A pinging noise while driving on CNG.
- Drop in Mileage: Fuel efficiency decreases suddenly.
- Frequent Backfires: Irregular combustion symptoms.
- Difficult Cold Starts: Engine takes longer to start on CNG.
If you’re facing any of these, consult your mechanic or visit a MIJO Auto Gas service point for diagnosis.
How a CNG Advancer Improves Mileage and Performance
The biggest benefit of a CNG Advancer lies in its ability to optimize ignition timing, ensuring better combustion. This directly translates into:
- Up to 15% increase in mileage
- Smoother engine pickup
- Less wear and tear on engine components
When paired with proper CNG kit maintenance tips – like regular filter cleaning and injector checks – your car can deliver petrol-like performance on CNG.
Is a CNG Advancer Necessary for BS6 Vehicles?
Absolutely. Modern BS6 vehicles come with stricter emission norms and advanced electronics. Installing a CNG Advancer tuned for BS6 compliance, like those from MIJO Auto Gas, ensures:
- Emission control system compatibility
- No warning lights or ECU errors
- Consistent fuel efficiency without engine strain
MIJO was India’s first to launch BS6 CNG/LPG kits with iCAT approval, making them a top choice for compliant installations.
Disadvantages of CNG Advancer (And Why They’re Avoidable)
While there are some concerns around CNG Advancers, most are due to poor installation or substandard components:
- ECU Errors if not properly tuned
- Wrong Timing Settings can affect performance
- Compatibility Issues with some engine models
These can be easily avoided by choosing a reliable brand like MIJO Auto Gas and getting installation done by certified professionals.
Advancer in Sequential CNG Kit: Why It Matters
In a sequential CNG kit, fuel is injected through electronic injectors, making ignition timing even more critical. A well-calibrated CNG Advancer ensures:
- Synchronization with petrol ECU
- Balanced air-fuel ratio
- Instant pickup without lag
MIJO’s sequential kits come with factory-calibrated timing advancers, giving drivers a seamless transition between petrol and CNG modes.
Which Is the Best Timing Advancer for CNG?
When looking for the best timing advancer for CNG, choose one that offers:
- Dynamic ignition control
- BS6 compatibility
- Heat and vibration resistance
- Certifications (ISO/ECE)
MIJO Auto Gas offers some of the most technologically advanced sequential CNG kits with built-in ignition timing optimization delivering the full benefits of a timing advancer, backed by 24+ years of experience in alternative fuel systems.
