INTRODUCTION & SAFETY PRECAUTIONS

1. INTRODUCTION TO CNG :

CNG (COMPRESSED NATURAL GAS) is obtained by compressing purified natural gas to less than 1% of its

volume at standard atmospheric pressure. CNG is a

colorless, odorless, non-toxic but inflammable and lighter than air.

BENEFITS OF CNG :

• CNG is principally comprised of methane. Due to low density it is compressed at a pressure of around 200 bars to improve the vehicle on board capacity .

• Lower maintenance costs when vehicles run on CNG.

• With rising petrol costs, CNG has seen the competitive

edge with its lower price and high availability.

• Vehicle life-span can be prolonged since there is no carbon generated during combustion and hence, engine and the oil in the engine are much cleaner.

• Due to its low hydro-carbon emissions, CNG is widely considered to be an environmentally viable alternative to petrol.

2. SAFETY PRECAUTIONS

T o get the best out of CNG fuel, the engine must be tuned and regularly serviced (both as regards to the mechanical and the electrical parts) in addition to routine maintenance required by the vehicle.

DO’S:

• Never carry out any repair work on your own or from any other personnel. Always get the car repaired / serviced at TATA authorized service centre only.

• Ensure that the Battery Ground terminal is disconnected before start of any repairs. Re-connect it once the repair activity is completed.

• Check CNG system components periodically for leakage.

• If you smell other than natural gas when refueling or if you hear a hissing sound, follow these directions:

a. Do not panic. Park your vehicle in a well ventilated

area and apply the parking brake. Roll down all the windows and keep the doors fully open for ventilation.

b. Turn the ignition switch to LOCK (0) position.

INTRODUCTION & SAFETY PRECAUTIONS

c. Switch off ignition switch and manual shut off knob

located on cylinder valve before servicing / repairing of any parts in the CNG circuit. Also ensure CNG gas

pressure at pressure gauge is Zero. For doing so, we can run vehicle in CNG mode after shutting off cylinder valve. Do not run the vehicle until leakage is rectified.

d. Immediately contact nearest TATA authorized

service centre for further assistance.

NOTE: In case of gas leakage, ECU will automatically switch the fuel mode from CNG to Petrol. The ECU will not allow you to switch to CNG mode until the leakage is rectified.

• Get CNG Cylinder checked after every 5 years at Govt.

approved test Agency. Never fill CNG cylinder with air, LPG or any fuel except CNG .

• Keep the car away from any Fire source.

• Remove the CNG tank during the welding/brazing work

on the Car.

• Check/replace air filter as per service schedule

mentioned. Clean it during every service.

NOTE:

• It is essential to have at least 10 liters of petrol AT

ALL TIMES to ensure trouble free operation in case of empty CNG tank.

• Run your car in petrol mode for at least 10kms after

every 300kms covered in CNG mode to keep the

petrol system in good condition.

INTRODUCTION & SAFETY PRECAUTIONS

DON’TS

• Do not install an LPG, Propane or any other cylinder in place of CNG cylinder. It is illegal and unsafe.

• Never alter CNG system confugration. Do not adjust / tamper CNG system settings. Never place inflammable, explosive, corrosive material and sharp objects near CNG cylinder.

• Never place inflammable, explosive, corrosive material near CNG cylinder.

• While loading or unloading particulars near boot area, take extra precaution for preventing any damage to cylinder and cylinder valve.

• Don’t smoke inside or near the CNG vehicle.

• Over filling the CNG cylinder can cause safety issues

like gas leakage. Please DO NOT over fill the tank beyond its capacity.

• Never use naked flame/fire to check gas leakages.

• Do not use high pressure washer fluid/water jets at

electrical devices & their connectors during washing. This is to prevent malfunction / failure of electrical system due to water ingress.

• Do not jump start your vehicle if you suspect any CNG leak.

• Do not drive your vehicle in case of CNG leak. CNG is flammable and highly explosive. You could be killed or seriously injured if leaking gas is ignited.

STARTING THE ENGINE

3. STARTING THE ENGINE

NOTE: Your Engine can start either in gas mode or in petrol

mode but it is always advisable to start in petrol mode and then switch to gas mode.

• To start, turn the ignition key to “IGN” position. Ensure the “MIL” lamp turns “ON”.

• Select the desired fuel operating mode by pressing the Fuel Selector Switch.

• Keep the clutch pedal fully pressed and crank the engine. DO not press the accelerator pedal.

• If the engine cranks but fails to start then repeat the above procedure. Release the key as soon as the engine starts. Ensure that the “MIL” lamp is “OFF”.

NOTE:

• Irrespective of the position of the fuel selector switch (Petrol or CNG), your car’s engine will start using petrol when the engine / coolant temperature is below 10°C (especially in cold winter) and later switch over automatically to CNG (if CNG mode is selected). Once the engine warms up, your car’s engine will start using CNG, if CNG mode is selected.

• During normal ambient (summer and other months), you car’s engine will start in CNG , if CNG mode is selected.

• Starting time in CNG will be longer than in petrol (approx 1 sec longer than petrol starting time) due to the physical characteristics of the fuel.

• Ensure that your car has sufficient petrol in the tank as petrol is used for starting until the engine warms up.

• Ensure that you run your car in “PETROL” mode for at least 10kms for every 300kms covered in “CNG” mode to ensure proper working of petrol fuel supply system.
