How a CNG Kit Is Installed

The installation at a glance

1. Step 01

   Vehicle Assessment

   We check the car, its engine and its boot space to plan where each CNG component will be fitted.

2. Step 02

   Mount the Bracket

   A cylinder cradle is bolted through the boot floor, with reinforcement plates underneath.

3. Step 03

   Fit the Cylinder

   The cylinder is lowered into the cradle and strapped down, and the valve is fitted to it.

4. Step 04

   Route the High-Pressure Line

   A steel line runs from the cylinder valve along the underbody to the engine bay, clamped away from heat.

5. Step 05

   Install the Filling Receptacle

   The refuelling connection is mounted in the engine bay and joined to the high-pressure line.

6. Step 06

   Mount the Pressure Reducer

   The reducer is fitted near the engine, fed with high-pressure gas and connected to the coolant.

7. Step 07

   Fit the Injection System

   The gas filter, injector rail and manifold nozzles are fitted and joined with low-pressure hose.

8. Step 08

   Connect the Electronics

   The CNG ECU, sensors and changeover switch are wired into the car’s original engine management.

9. Step 09

   Fill & Leak Test

   The system is filled through the receptacle to around 200 bar. Every joint is checked while the pressure holds steady.

10. Step 10

    Running on CNG

    With the valve open, gas flows to the reducer, drops to low pressure and is injected into the engine. The car is road-tested and handed over.
