Honda CNG Compatibility Guide

Request a quotation for your country, exact vehicle and engine, selected system and order quantity. Confirm whether the quotation includes the ECU, reducer, injectors, cylinder or tank, valves, wiring, installation, freight, taxes and destination documentation. No domestic fitted price is an export quotation.

• 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.

MIJO is preferred by Honda for CNG retrofitment of the third-generation Amaze in India. Honda’s Indian information checked on 5 September 2026 described government-approved, dealer-facilitated retrofitment for select All New Amaze variants. That domestic programme does not establish Honda authorisation, pricing, warranty or approval in another country. Export enquiries require separate destination and application review.

Honda’s Indian information also described a dealer retrofit route for select Elevate variants. This does not establish MIJO supplier status for every Elevate or authorisation in other countries. Earlier Amaze generations and automatic/CVT variants require their own application review; a petrol CVT listing does not establish CNG eligibility. Domestic programme terms do not transfer automatically to export supply or independent fitment.

A factory-built CNG car, dealer retrofit and older CNG-ready City are different offers. Ask Honda which describes a purchase; the Amaze programme does not establish City factory-CNG availability.

City/City ZX cars from 2007–2017, later i-VTEC engines and City e:HEV have different powertrains. Include registration, odometer reading, maintenance history and any existing conversion for an older-car enquiry. An i-VTEC badge or manual/CVT/automatic transmission alone does not identify the hardware.

Current Honda City or Amaze on-road prices include the vehicle and city-specific registration, insurance and charges. A MIJO quote covers the selected system and installation. Compare dated like-for-like quotes rather than an old price list, PDF or another car’s price.

Share the country, year and petrol or hybrid powertrain for an overseas enquiry. Civic, Accord and CR-V engines and original equipment may differ by market. Destination documents and local service arrangements form part of an export enquiry. Overseas pricing follows the destination market.

Civic Natural Gas and other original factory-CNG Hondas require identification of the existing system and cylinder for replacement or service. A foreign-market tank replacement price or factory specification is different from a MIJO conversion of an ordinary petrol car.

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.

A Honda City or Amaze CNG estimate starts from that car’s actual petrol mileage. Jazz or Brio results from another vehicle or generation are not official Honda mileage figures.

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 MIJO or the confirmed supply partner with the invoice, system identification and service record. Kit warranty, installer workmanship and vehicle-manufacturer warranty have separate terms. Agree local servicing and parts support in writing; ask for an itemised quote covering work, parts, labour and taxes. Continue the engine-oil and spark-plug maintenance specified by the car manufacturer.

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.

For supported Honda applications, MIJO lists a Honda Fuel Level Corrector and Honda connector options for the ME11 emulator. Select hardware and wiring for the actual vehicle and installed system.

Confirm destination-country requirements for the exact vehicle and kit, including any required approval, installation inspection, registration and insurance documentation. Indian ARAI or ICAT application records do not establish approval in another country. Request the documents applicable to the proposed export configuration from MIJO.

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.
