Hyundai CNG Compatibility Guide

Your dealer provides a dated quotation with one complete fitment price for the kit and installation, including cylinder mounting, installation labour, calibration and operating checks. Documentation charges and accessories outside the standard kit may be quoted separately. Confirm the cylinder specification, applicable taxes, final payable total and written warranty before installation.

The complete system includes the selected ECU, reducer, injector rail or mixer, sensors, switch, valves, wiring harnesses, pipes and standard installation accessories.

Compare the specified system, calibration, local service and warranty. Gold, Premium, “Italian kit”, imported origin or online rankings alone do not identify the right system.

• Conventional: gas is mixed with the intake air through a mixer.
• Sequential: an ECU controls gas delivery through individual injectors.
• DPI (Dual Point Injection): two port injectors per cylinder require the corresponding Sequential configuration. MIJO’s four-cylinder, eight-injector DPI configuration uses a dedicated 4×8 ECU.
• DI (Direct Injection): requires a dedicated system developed for the direct-injection engine.

These are MIJO’s system categories; availability follows the engine applications described on this page. DPI differs from Direct Injection; turbocharging alone does not distinguish MPI, turbo-MPI and DI.

MIJO Direct Drive 2.0 uses KME ECU technology from Poland for supported DI applications.

CNG means Compressed Natural Gas. In a Sequential system, the reducer lowers gas pressure, injectors meter gas and the ECU coordinates delivery. Three-cylinder, four-cylinder and other supported configurations use the corresponding ECU and injectors.

Standard port-injected Sequential systems start on petrol and change automatically to CNG at calibrated operating conditions; the driver can select petrol when needed.

Hyundai Venue CNG options differ between the Kappa 1.2 MPi petrol engine, which uses Sequential for eligible applications, and the 1.0 Turbo GDi, for which MIJO has a technically developed DI solution. Creta 1.5 MPi and 1.5 Turbo GDi likewise use different system categories. Earlier cars, including Creta 2020, retain their own specifications.

The standard i20 1.2 L Kappa with manual or IVT differs from Turbo GDi and N Line applications. Older i20 Active, Elite i20 and 2012–2018 models also retain their original engines. Older i10/Grand i10 1.2L Kappa or Kappa2 cars differ from Grand i10 Nios. Hyundai BS6 applications include DPI; a facelift or base-model name alone does not identify the system.

An on-road price includes buying the vehicle; a MIJO quotation covers conversion of your existing petrol car.

Hyundai’s listings checked on 5 September 2026 showed petrol for the standard i20 and petrol/diesel for Venue and Creta, with no factory CNG variant shown for those ranges. Grand i10 Nios Hy-CNG Duo was separately listed with two cylinders. Its layout, boot space and warranty belong to that factory vehicle.

For current i20 or Venue factory-CNG availability, launch information, a Prime SD fleet purchase or new/used vehicle prices, ask Hyundai. Ex-showroom and on-road prices include the vehicle and applicable city-specific registration, insurance and charges; MIJO retrofit pricing covers conversion.

MIJO supplies independent aftermarket systems and support. This does not represent Hyundai genuine-accessory, factory-supplier, showroom-installer or Hyundai-authorised service status.

Divide distance travelled on CNG by kilograms refilled over comparable fills. CNG mileage is measured in km/kg; petrol mileage uses km/l. Traffic, load, driving style, vehicle condition and calibration affect the result.

For running cost per kilometre, divide the local fuel price by actual mileage in its matching units. The calculator uses local fuel prices and monthly kilometres to estimate savings and conversion payback. Estimates are not guaranteed or factory-certified mileage.

Litres describe water capacity, not gas weight. For a standard system, a 60 L cylinder holding about 8 kg at 15 km/kg gives an estimated 120 km range. Actual fill varies with residual pressure, gas temperature, station pressure and cut-off.

Compare cylinder size, weight, mounting, valve access, ground clearance, usable seating, luggage and spare-wheel access with your normal passenger load and any commercial equipment. Factory boot volume or another car’s installation does not specify the space remaining in yours.

Confirm the cylinder manufacturer, specification and applicable cylinder documents. MIJO supplies the conversion kit; cylinders are sourced from cylinder manufacturers.

Contact your MIJO fitment centre with the invoice, system identification and service record. MIJO kit warranty, installer workmanship and vehicle-manufacturer warranty have separate terms. Service cost depends on the work required; ask for an itemised quote covering work, parts, labour and taxes; continue the engine-oil and spark-plug maintenance specified by your car’s owner’s manual.

For poor running, warning lights, fuel-level readings or calibration, provide ECU/component identification, installation history and symptoms. Software and wiring downloads and replacement filters, reducers, switches, sensors, emulators and other components and accessories must match the installed system. Installation includes calibration, leak and operating checks and a road check.

Within MIJO’s Conventional and Sequential range, suitable BS3 petrol applications can use Conventional or Sequential; from BS4 onward, port-injected MPI or MPFI applications use Sequential. BS4 and BS4 OBD2 are separate approval stages, alongside BS6 Phase 1 and BS6 Phase 2. The emission stage alone does not identify injection technology.

For Conventional and Sequential fitment, obtain the applicable vehicle-kit approval documents, including certificate validity, manufacturing year and emission scope, and confirm the local RC endorsement and insurance process. ARAI or ICAT references identify the testing agency; RTO registration is a separate step.

Before fitment, your dealer checks the vehicle condition and confirms the applicable vehicle-kit approval.

MIJO does not support the use or installation of a second-hand CNG kit. Choose a new, complete MIJO kit installation with applicable approval documents and written warranty terms.

MIJO develops and manufactures CNG and LPG systems in Kundli, Delhi NCR. Established in 2001, its in-house product development, tooling, machining, assembly and testing support a company-wide record of 1 Million+ Customers, a 1,000+ Dealer Network and exports across 17+ countries. See our manufacturing capabilities.

Export partners can arrange destination-market documentation, training, spare parts and after-sales service support through MIJO.

Diesel, battery-electric, two-wheeler and heavy-vehicle applications are outside this passenger-car petrol-to-CNG guide. LPG requires a separate system, tank, storage components, assessment and quotation; CNG prices, km/kg figures and fill estimates do not describe LPG. Explore Sequential LPG.

For a Hyundai already fitted with factory LPG or CNG, identify its existing fuel system before new work. Include the actual manual, automatic, AMT, IVT or DCT transmission in the enquiry.
