TRUCK & BUS CNG CONVERSION · 100% CNG
100% CNG for trucks and buses.
MIJO engineers engine-specific sequential monofuel CNG conversions for compatible trucks and buses. Each project brings engine conversion, spark ignition, ECU management, sequential gas delivery, vehicle installation and calibration together around the exact engine and operating duty.
TRUCK & BUS ENGINE SOLUTIONS
CNG solutions for major truck and bus engines.
MIJO has engine-specific 100% CNG conversion solutions for compatible Tata Motors, Ashok Leyland, Eicher, SML Isuzu / Swaraj Mazda, Sinotruk and other truck and bus engines. The exact engine, rated power, emission level and operating duty determine the final solution.
HEAVY-DUTY CONVERSION ARCHITECTURE
More than a bolt-on gas kit.
Converting a heavy diesel engine to dedicated CNG operation requires coordinated changes to the combustion system, ignition, electronic controls and fuel delivery. The final architecture is defined only after the exact engine and operating duty are confirmed.
Engine core conversion
The confirmed engine programme defines the required pistons, rings, liners and supporting service work for dedicated CNG combustion.
Cylinder head & ignition
Cylinder-head work, spark-plug provision and ignition hardware replace diesel compression ignition with electronically controlled spark ignition.
ECU, sensors & protection
Matched engine signals support ignition timing, gas delivery, diagnostics and protection limits for temperature, speed and load.
Sequential CNG fuel system
Pressure regulation, manifold sizing, sequential multipoint delivery, high-pressure plumbing and storage integration are engineered around engine demand and vehicle duty.
The result is dedicated 100% CNG operation. This is not a diesel-CNG dual-fuel blending system.
SINOTRUK HOWO CNG SOLUTION
Sinotruk HOWO
WD615.47
A dedicated 380 HP sequential monofuel CNG conversion for the HOWO WD615.47 engine.
For the WD615.47 application, MIJO integrates the required engine-core and cylinder-head work with electronic ignition, matched sensing, sequential multipoint gas delivery and vehicle-side CNG installation. The complete specification is finalized for the confirmed vehicle, operating duty and installation layout.

TRUCK + BUS APPLICATIONS
One engineering route, configured for the confirmed engine.
MIJO studies the engine first—not a generic vehicle category. Truck or bus application, rated power, emission level, load profile and operating conditions determine the final 100% CNG configuration.

FROM STUDY TO SERVICE
A complete conversion-project workflow.
The proposal is built around the actual vehicle and operating duty, not a generic component list.
Vehicle & duty study
Make, model, engine code, power, emission level, route, load and operating hours establish the project basis.
Engineering specification
MIJO defines the engine work, control strategy, fuel system, storage architecture and installation scope.
Conversion & installation
The engine and vehicle systems are converted and installed to the confirmed technical configuration.
Calibration & commissioning
Ignition, gas delivery, safety limits and drivability are commissioned for the actual vehicle and operating duty.
Training & after-sales
The project can include technician training, service planning, spares support and post-installation coordination.
FLEET PROJECT DELIVERY
Built around the actual vehicle and duty.
MIJO works with fleet operators, workshops and technical partners on vehicle selection, conversion planning, installation, commissioning, technician training, spares and after-sales support.
The final supply and support scope is defined for the confirmed vehicle, fleet size and installation arrangement.PREPARE YOUR ENQUIRY

PROJECT QUESTIONS
Before a truck or bus is specified.
What does 100% CNG monofuel mean?
The compatible heavy-duty engine is converted for dedicated spark-ignited CNG operation, with electronic control and sequential multipoint gas delivery engineered as one system.
Can every diesel truck or bus use the same conversion?
No. Engine construction, power, emission level, vehicle packaging, load profile and local requirements all affect the engineering scope. MIJO confirms suitability before a proposal is issued.
Which truck and bus platforms can MIJO study for conversion?
MIJO handles project enquiries for compatible Tata Motors, Ashok Leyland, Eicher, SML Isuzu / Swaraj Mazda, Sinotruk and other truck and bus platforms. The exact vehicle and engine must be studied before suitability and scope are confirmed.
What is included in the Sinotruk HOWO WD615.47 programme?
The HOWO programme covers engine-core and cylinder-head conversion, spark ignition, electronic management, sequential multipoint CNG delivery, matched sensing, safety monitoring and the vehicle fuel-system installation.
How is a fleet saving estimate prepared?
A project estimate must use the fleet's actual annual distance, route, load, diesel consumption and local diesel and CNG prices. MIJO does not apply one generic saving figure to every truck or bus.
What support can accompany a fleet project?
The project scope can cover installation and commissioning, technician training, spare-parts planning and after-sales coordination.
