NTRODUCTION
Currently, there is little to the environment to
further stabilize the economy it is necessary to
increase and improve the production structure of
cars that emit harmful substances and have high
fuel efficiency. The following main requirements
are imposed on modern piston internal
combustion engines: the lowest level of negative
impact on the environment; the degree of
perfection of conversion of thermal energy into
mechanical energy, or the smallest value of the
specific fuel consumption and the smallest
consumption of friction; a wide range of
maximum torque and power values; the high
value of litre capacity; the smallest values of
specific mass and overall dimensions; reliability
and long-term service of construction elements;

a limited resource [1-4]. According to IAEA, OPEC,
UN Industrial Development Department and
World Energy Agency (WEA) forecasts, the share

Currently, in the world, approximately 5 billion in
1 year. tons, in Russia - 0.5 billion tons, and in
Uzbekistan - 6 million. tons of oil is being
extracted. It should be noted that 19 million in 1
year in the USA. barrels (2.9 million tons) of oil
are used, and according to the American
Petroleum Institute, 43% of oil products are used
as light fuel for cars, 11% - as diesel fuel, 9% - as
aviation fuel, 16% is used as an oil, tar, plastic, 4%
as furnace fuel, 5% as heavy fuel and 12% as
miscellaneous fuel. Such dynamics of the use of oil
products require the use of their substitutes -
alternative motor fuels. In this regard, in almost
all highly developed countries, scientific and
practical work related to the rationalization of the
balance of fuel and energy resources and
alternative fuels for various types of transport as
the most energy-consuming sector of the
economy is carried out. is going It is known that
the following are included in the range of
alternative fuels: synthetic gasoline derived from
coal, combustible shale, peat, natural gas; benzo-
methanol and benzo-ethanol mixtures; hydrogen;
liquefied petroleum gas propane-butane (SNG);
compressed natural gas (SPG) or liquefied natural

ITERATURE ANALYSIS AND METHODOLOGY
The results of studies on the toxicity of gas
cylinder cars analysis show that when natural gas
is used instead of gasoline, the release of toxic
substances into the environment (g/km) is, on
average, 8 times higher in carbon monoxide, 3
times higher in hydrocarbons, and 3 times higher
in nitrogen oxides. by 2 times, by PAU
–
10 times,
by smokiness
–
9 times. Therefore, the world's
leading scientists and researchers are doing a lot
of work on the use of alternative fuels for vehicles,
as well as on improving the transition of vehicles
to gas fuel. In our republic, there are several
regulatory legal documents on the use of gas
cylinder cars and their safe operation, and special
requirements are set in them [18-21]. Including

ESULTS
The results of experimental studies show that
compressed natural gas containing 83...96%
methane contains 25% hydrogen by mass and has
a high octane number (OCHM=130) and therefore
=13 can burn without detonation, which makes it
possible to reach the effective useful work
coefficient ηe=0.36. Natural gas produces on
average 40% less SN, 75% less SO, 25% less SO2
than gasoline, and 80% less SN+NOx and 50% less
SO than diesel. is formed. In a gas engine created
based on a diesel engine, the emission of nitrogen
oxides is 0.44...14.0 g/km, the emission of
hydrocarbons is 0.8...1.9 g/km, and the emission
of carbon oxides is 2.8...11, reduced by 6 g/km.
The problem of transferring different types of fuel
to the engine cannot be solved without analyzing
and taking into account their following
properties: - physical-chemical properties, which
usually determine the engine's operation and the
structural features of the fuel supply or supply
system, energy (thermal-technical) properties,
they determine the quality and character of the
combustion process and the working process of
the engine; - gasodynamic and technological-
production properties, which are connected with
obtaining, transportation, refuelling and storage
of fuels; toxicity properties, which determine the
effect on the environment. According to the
above, alternative motor fuels can be classified
according to a number of their characteristic
features (Chart 1). Smoke the gas can be burned
without forming soot and other products of
incomplete combustion. It is relatively easy to
clean gas from sulfur compounds and provide
high-quality consumers with sulfur-free fuel,
which does not produce SO2 and SO3.
Classification of alternative motor fuels natural
gas has several important advantages compared
to oil-derived or other alternative motor fuels, as
well as unique physicochemical and operational
properties. Thermomechanical characteristics of
gaseous fuel are usually under normal conditions
for 1 m3 of gas, i.e. pressure 760 mm sim above
and conducted when the temperature is 0 ℃. In
addition to the normal conditions of the gas, its
standard conditions are also distinguished, the
pressure of which is 760 mm rt. St. and the
temperature are 20℃. In technical literature, the
pressure is 760 mm rt. St. and the characteristics
of the gas at a temperature of 15 ℃ are given

ISCUSSION
Currently, natural gas is used as motor fuel in the
world there are more than 20 million vehicles.
The unique physicochemical properties of natural
gas, its considerable natural reserves, the
development of the gas pipelines from the place
of extraction to the place of delivery, and the
environmental advantages of natural gas
compared to traditional types of fuel make
natural gas the most promising and universal

engine of the 21st century. Allows you to look at
it as fuel. The use of natural gas as a motor fuel is
an intensively developing direction, which will
become an independent high-profit sector of the
gas industry shortly. There are all reasons for the
annual volume of natural gas use in automobile
transport to reach 5...6 billion m3 in 7...10 years,
and to increase from 20...25 billion m3 in the long
term. Our republic also has many reserves of
natural gas, and these reserves contain high-
quality natural gases that can be used as fuel for
automobile engines directly, without the use of
excess gas processing or chemical treatment
technologies. Can be used as fuel. From 1991, the
production of natural gas in Uzbekistan increased
from 41.9 billion cubic meters to 50.4 billion cubic
meters in 1997, per m3 and 60 billion in 2013,
m3, which made our country eighth place in the
world in terms of gas extraction. The richest gas
region is Ustyurt, 60% of its territory is in
Uzbekistan. Gas extraction is mainly based on 12
fields, which are mainly located in the
southeastern region of our country. The main
advantage of the use of gaseous types of fuel is the
economical use of tractor equipment. The reasons
for this are: their price is cheap compared to types
of fuel obtained from oil; extended engine service
life, spark plug and oil change periods, higher fuel
octane number and no soot formation during
combustion. In practice, all types of wheeled
machinery and stationary equipment running on
gasoline and diesel can be converted to natural
gas fuel. However, during the transfer of vehicles
to gas fuel, it is necessary to transfer vehicles with
the following functions: intercity and intercity
passenger buses; cars of municipal utilities; route
buses and minibuses; all types of trucks operating
in the city; agricultural and road construction
equipment and stationary devices with
appropriate infrastructure; trucks working in
closed
buildings
and
warehouses.
The
operational properties and fields of application of
gases are determined by their composition. The
need for gas and its transportability largely
depend on the heat of combustion. Gases with a
high heat of combustion are transported over
long distances, and those with a low heat are used
near the place of production. According to the
combustion heat, gases are divided into the
following groups: very high combustion heat
(above 25000 kDj/m3)
–
liquefied, released
together with oil, natural; with high combustion
heat (12000...25000 kDj/m3) - coke, biogas, mine,
carburized water obtained by degassing of coal
seams;

unproductive fuel, air domain; the heat of
combustion is very small (less than 3000 kDj/m3)
- vagrant, water gas generators with aerial
spraying, obtained in the ventilation of coal
mines. When the engine runs on gas fuel, due to
the resistance of gas fuel to detonation, it is much
easier to fire it and service the devices that use the

ONCLUSION
It runs on natural gas, which is cheap today
engines are widely used in modern city vehicles.
It mainly uses natural, industrial and synthetic
gases in compressed or liquefied form. Natural
gas used as a motor fuel has several advantages
over petroleum products. When using them, high
technical and economic indicators of the engine
are achieved, because natural gas has very good
anti-detonation properties, and the property of
forming a mixture with air is very good. When the
engine runs on gas fuel, the mixture burns almost
completely, and the environment is less damaged
due to the much lower toxicity of the used gases.
Therefore, approximately 70-80% of cars in our
republic run on natural gas fuel. Compressed
natural gas is a gaseous state under normal
conditions at any pressure, and its composition
consists mainly of methane and hydrogen. The
use of gases eliminates the washout of the oil film
from the walls of the piston and sleeve, and
reduces the formation of soot in the combustion
chambers, due to the absence of gasoline vapours,
the oil on the walls of the cylinder liners does not
burn, as a result, the life of the engine and the oil
change period is 1.5 - Extends by 2 times. The use
of gas fuel reduces the total amount of harmful
carbon monoxide, nitrogen dioxide and
hydrocarbons in the exhaust gases from the
engine. The toxicity of exhaust gases is 3 times
less when burning gas fuel than when working
with gasoline, and the level of noise emitted by
the engine when it correctly selects the operating
mode is low, and this condition is especially
important in urban conditions. Therefore, a lot of
work is being done to convert cars to gas fuel and
improve gas cylinder equipment.
