This document provides information about compressed natural gas (CNG) vehicles. It discusses the benefits of CNG which include lower costs, better engine life, and reduced emissions compared to gasoline. Proper training is required for maintenance on CNG vehicles since the oil does not need to be changed as frequently. The top countries using CNG vehicles are Iran, Pakistan, and Argentina. In conclusion, while CNG vehicles have advantages, their tanks require more storage space and initial costs are higher than gasoline vehicles.

4. WHAT IS CNG?

5. PREPARATION

9. Proper training is required for all
maintenance personnel working on CNG
vehicles. The oil in a CNG vehicle does
not need to be changed as frequently
because CNG burns more cleanly than
gasoline , producing less deposits in the
oil.

10. FIRST BIKE AND CAR OF CNG

12. PROPERTIES
Light than Air.
Colourless and
odorless.
Does not catch fire
easily.
Density
Non toxic

13. (1)- Economic Benefit
(2)- Environment Friendly
(3)- Engine Life Improves
(4)- Safety

14. ECONOMIC BENEFIT
 It is cheaper than Petrol
and Diesel.
 Domestic production.
 On an average CNG costs
around half or 1/3rd the
amount regular fuel.
 NO Price fluctuation.
 Lower maintenance cost.
 It is facilitates high running
with lower cost.

17. DISADVANTAGES
 CNG tank require
high storage space.
 CNG made engine
vehicles are costly
more than other
fuel engine of the
same car.

18. CNG filling
stations have
limited
availability as
compare to
gasoline.
CNG engine Is
low power
engine than the
gasoline engine.

19. USES
