INTRODUCTION

Natural gas is a fossil fuel comprised mostly of 87% methane,

and is one of the cleanest burning alternative fuels.

It can be used in the form of:

Compressed natural gas (CNG)

Liquefied natural gas (LNG)

What is CNG?

A natural gas under pressure (3600 psi/248bar) which remains

clear and non-corrosive.

It is odorless so NG companies add “smell” so that it can be

detected.

It’s octane rating is 130.

CNG’s /NGV’s HUMBLE BEGINNINGS

The First Natural Gas Vehicle 1860

The first internal combustion engine (ICE) vehicle to run on

natural gas was created by Etienne Lenoir in 1860!
