Abstract: Nowadays, the requirements and dependency of on fossil fuels is increase due to increase in number of
people on vehicles are increasing day by day which lead to high vehicles and their applications, this leads to increase in the
emission of flue gases and it results in the severe environment
pollution. Many researchers have done research to improve the
consumption of fuel. Vehicles plays an important role in the
efficiency of IC engine. The main reason for less efficiency is the daily life but it has some drawbacks such as incomplete
incomplete combustion of fuel in the IC engine. To improve the combustion of fuel leads to increase in air pollution, increase
efficiency, we carried out the experiments with two stroke petrol in greenhouse effect and emits poisonous gases in our

B. CALCULATION FOR AIR

Given, W0=1, Cv = 47100, S1=2, S2=1
We have, Load (S1-S2) =1, Time = 75sec, rpm = 140
Wnet = [(S1-S2) + W0] 9.81 = [(1-2) + 1] 9.81=19.62 N
Torque (T) =Wnet × 9.81 × 0.1 = 19.62×9.81×0.1=19.24 Nm

Fig. 6 shows that the specific fuel consumption is

increased in case of preheated pure oxygen compared to
the air with respect to applied load (S1). This means that
the heat supplied by fuel is reduced in case of pure
oxygen.

Fig. 7 shows that the Brake thermal efficiency is increased in

case of preheated pure oxygen compared to the air with
respect to applied load (S1). This means that the heat supplied
by fuel is reduced in case of pure oxygen. Now, similarly all the values of Break power, torque, Specific
fuel, consumption, Wnet, fuel consumption, engine heat, and
Efficiency are obtained by above formulas, similarly for 4kg
,6kg ,8kg are obtained see it in observation tables.

C. Calculation for Pure Oxygen

Given, W0=1, Cv = 47100, S1= 2, S2 = 0.5

We have, Load (S1-S2) = 1.5, Time = 80sec, rpm=180
Wnet = [(S1-S2) + W0] 9.81 = [(2-0.5) +1] 9.81=24.525 N
Torque (T) =Wnet × 9.81× 0.1 =
24.525×9.81×0.1=24.059Nm
