Abstract
One of the challenging problems in big cities has always been the pollution caused by car smoke, which is the result of the remains of fossil fuels, especially gasoline, whose main and dangerous compounds include carbon monoxide, hydrocarbons, nitrogen oxides and carbon dioxide. Of course, it is worth mentioning that carbon dioxide production indicates the complete burning of gasoline, which is the main goal of optimal combustion. Considering the chaotic and polluted conditions of the cities' air, the only major change will be in reducing fuel consumption and the level of pollutants resulting from the incomplete combustion of this half-breathed air. In this paper, changes have been made with a small cost in the electrical system and the intake of cold air and the exhaust of smoke in order to burn fuel in the car engine, the result of which is a reduction of more than 50% of pollutants, a reduction of 25% in fuel consumption, along with an increase of about 33% in the power and acceleration of the car.

Keywords: gasoline, carbon monoxide, hydrocarbon, carbon dioxide, nitrogen oxides, acceleration.

1. Introduction
Now that the pollution caused by the incomplete combustion of the fuel in the cars is increasing day by day on the smoky and allergic lungs of the city dwellers, it is time to think of a solution. Even the production of hybrid and electric cars with all the facilities and advantages does not tempt car drivers due to the complexity and special problems. These cars do not work well in very hot and very cold weather. One of the ways to reduce fuel consumption and reduce the level of pollutants is by focusing on increasing the compression ratio, but it is not enough. With access to complete combustion, while reducing fuel consumption and the level of pollutants, we can achieve higher power and acceleration, which is the strength of the world's top automotive brands.

2. The importance and necessity of access to optimal combustion
- Reducing the level of pollutants from gasoline fuel in internal combustion gasoline engines
- Reducing fuel consumption and maintaining national reserves
- Increasing the efficiency of the engine, including the power and acceleration of the car

3. Definition of variables
The items related to optimal combustion include the following:
- Modifying the vehicle's electrical and ignition system
- Modification of the cold air intake system of the engine
- Modification of the smoke and hot air exhaust system of the engine
- Iran Khodro's Peugeot Pars 8-valve engine with the abbreviation XU7, model year 2008

In this section, each of the above items are examined.

3.1. Electrical and ignition system
The car's electrical system includes a double coil (Fig. 7), spark plug wire (Fig. 3) and spark plug (Fig. 2). In new cars, due to current loss and rapid failure and the possibility of electricity theft, the spark plug wires have been removed and the coil is installed directly on the spark plug. The car's ignition system is being developed due to the sensitivity of the vehicle. The function of the ignition system is such that after the suction of fuel and air from the manifold with the rising of the piston, the mixture of fuel and air is condensed and at the limit of the dead point according to the advance calculated by the electronic control unit (ECU), the current pulse is sent from the ECU to the double coil and from the coil to the spark plug wire and from there to the spark plug and turns into a spark in the spark plug, causing the fuel and air mixture to explode, and the resulting force of this explosion causes the piston to go down and rotate the crankshaft, gearbox, wheels and the so the car accelerates. Fig. 4 shows the combustion system from the engine door.

3.2. Cold air intake system
The oxygen required for the combustion operation in the engine is supplied from the available air, usually the air enters the air filter chamber from the top of the front window of the car through the pipe, and after purification, enters the cold air manifold, and after injectors spray, it enters the combustion chamber along with gasoline. Of course, in the GDI system, after the air enters, the fuel is injected directly onto the spark plug in the combustion chamber, and after the spark, the mixture of fuel and air explodes. Fig. 5 shows the view of the air filter, which has the task of cleaning the air entering the engine, and Fig. 6 is the cold air intake system shown from the engine door.

3.3. Smoke system and hot air exhaust of the engine
When the piston rises and the smoke valve opens, the smoke resulting from combustion enters the exhaust through the smoke manifold after passing through the built-in accumulators in the exhaust path and reducing the sound and lowering the temperature in order not to cause a thermal shock to the engine, is released from the exhaust pipe embedded in the end of the car. The above cycle has a significant impact on engine performance in such a way that reputable brands such as K&N, by manufacturing and supplying smoke manifolds and special exhaust pipes, take up to 35% of the engine's price to increase engine performance. The image of the catalyst is shown in Fig. 7, which is responsible for the complete oxidation of the partially burnt gases coming out of the engine, and Fig. 8 is the image of the middle exhaust source, which is responsible for lowering noise and slowly reducing the temperature of the exhaust gases to prevent thermal shock and damage to the engine, and Fig. 9 shows the rear exhaust chamber, which is responsible for reducing noise and temperature.

3.4. Peugeot Pars 8-valve Iran Khodro engine with the abbreviation XU7 model year 2008
The Peugeot Pars engine is a four-cylinder in-line engine with a volume class of 1761 cc, which was produced in two types: normal and 16-valve. Currently, the normal engine type of this car includes 8 valves, so that each cylinder has one inlet valve, i.e. gas valve, and one outlet valve, i.e. smoke valve, which produces a power equal to 100 horsepower. The normal Peugeot Pars engine is XU7JP, Peugeot-Citroen engine. (Fig. 12), which is called LFZ in Europe and L3 in Iran. L3 is a 1.8-liter in-line 4-cylinder engine with fuel injection whose camshaft is on the cylinder head or so-called OHC, which has 8 valves and a maximum power of 100 horsepower at 6000 rpm and a maximum torque of 153 Nm at 3000 rpm. This engine is controlled by a central ECU. This engine is also used in SAMAND and Peugeot 450 cars in Iran. The fuel consumption of this car in 100 kilometers
by obtaining information from the Iran Khodro site [7] is 7 liters on the road and 13.8 liters in the city. According to this information with a factor of 31% for urban consumption and 69% for road consumption, it reaches a combined consumption of 9.1 liters per hundred kilometers. Normal Pars car view is shown in Fig. 10, and Fig. 11 is the view of the XU7 engine from the engine door.

4. Modification
After checking the ignition system of the car, the following changes were made: the coil was of good quality, and by installing two capacitors, better conditions were created for creating a spark, and the spark plugs and wires were replaced with better quality ones. In the engine's cold air intake system, the bottleneck points that had a negative and reducing role in the air intake speed were identified and the conditions to increase the air intake speed were provided with the innovative part. Due to the high temperature and pressure of the exhaust air, the hot air exhaust system had more difficult conditions for the installation and welding of the innovative part, and in case of the slightest weakness in the welding, the part was separated and blocked the way of smoke exhaust. After investigations and choosing the best points for welding and after proper grinding, with regard to providing excellent conditions for intaking air to the cylinder head compartment and proper ignition for optimal combustion, the exhaust was installed in its place after removing the catalyst. The removal of the catalyst was subject to the passing of the pollution tests at the car technical inspection centers, and if it does not pass, the catalyst must be installed again in its place after the manifold. The total cost of the changes was about 129 US dollars, which is a small cost considering the results obtained.

4.1. Engine pollutant testing at SIMFA integrated center
The car was transferred to the SIMFA car technical examination center [3] for pollutant testing and fortunately, despite the removal of the catalyst, due to the ease of air intake and the availability of sufficient oxygen for optimal combustion and suitable conditions for the easy release of smoke, it passed all the tests. The pollution conditions in the second half of 2017 had become much stricter; for example, the amount of carbon monoxide emission had decreased from 2.5 in the first half of 2017 to 0.7 in the second half, and this 357% improvement has taken place in a situation where significant progress in quality improvement of Iran manufactured cars or fuel consumption is not observed; therefore, in the current situation, the usefulness of this paper is more evident.

4.2. Acceleration and engine performance test at Al-Ghadir racing track (in Ahwaz city)
The improvement in the working conditions of the car's engine was quite tangible and obvious. The initial acceleration had increased significantly, the engine had become much smoother and quieter, and the reduction in gasoline consumption was very noticeable. During a meeting with Mr. Jawanmardi, the honorable president of Khuzestan Automobile Racing Federation [2], it was decided that the car will be transferred to the track for testing and drag with a similar car that has been reinforced in the standard class. The chosen car was a Peugeot Pars model 2012 and its different parts including the valves in the standard class were replaced by the enhanced type, and it was practically the best standard car on the track, and it belonged to the head of the federation. The two cars were placed on the track and were dragged by professional drivers, and the best standard car on the track was by a considerable distance at the start of the drag (gears 1 and 2) fell behind and surprised
the professional tuners of the federation, and this success indicated the excellent performance of the engine and the effectiveness of the modifications.

5. Case study and test results
All Peugeot Pars car information is available on the Iran-khodro website and it is considered as the information base, and the car pollutant level is determined by the strict rules of the integrated technical inspection centers of the major cities of SIMFA, and the permissible range is defined for the pollutant level by these centers. The results of the pollution test are listed in Table 1.

Table 1. Pollution test results
Row Pollutant type Latin name Allowed range The results
1 Carbon monoxide CO 0-0.7 0.36
2 Hydrocarbon HC 0-250 54
3 Carbon dioxide CO2 0-15 14
4 Oxygen O2 0-3 0.21


The tested items include carbon monoxide in the range of zero to 0.7 and the above item was passed with an excellent number of 0.36 and the range of hydrocarbon emissions is between 0.0 and 250 and this item was passed with an excellent number of 54 and the high production of carbon dioxide and high consumption of oxygen in the smoke, respectively,14 and 0.21, indicate an optimal and desirable combustion. The full information on the acceleration and gasoline consumption of the car is listed on the Iran Khodro website, and the comparison of the acceleration and consumption test is mentioned in Table 2.

Table 2. Comparison of car specifications after changes with the standard mode
Row Description of specifications Standard car Improved car Percentage improvement
1 Zero to hundred acceleration 11.9 9.2 1.29
2 Urban consumption 13.8 10 1.38
3 Road consumption 7 5.5 1.27
4 Consumption media 9.1 6.9 1.32
5 consumption in 120 km 9 6.77 1.33


Zero to hundred acceleration represents the time it takes for the car to reach a speed of 62 miles or 100 kilometers from the start of movement, and it is called zero to hundred for convenience, and the shorter this time is, the more agile and sporty the car is, and it is one of the advantages and strengths of a car. Urban consumption is the amount of gasoline consumed per liter to travel a distance of 100 kilometers in the city, and road consumption is the gasoline consumed per liter while traveling a distance of 100 kilometers at a speed of about 95 kilometers in gear 5 for this car. Almost the most optimal mode of operation of 4-cylinder engines is in the range of 2500 to 2750 rpm, and by placing the gearbox in the highest gear and adjusting the engine speed in the above range, the best road consumption can be achieved.

Providing a solution for the existing technical problem along with an accurate, sufficient and integrated description of the invention
The widespread use of internal combustion engines even in ultra-advanced hybrid vehicles, the problems of environmental pollution with bulky worn-out batteries of electric vehicles and the impossibility of fully recycling these batteries show the dependence of vehicles' motion on fossil fuels due to the ease of use and durability in refueling periods. Therefore, solving the above-mentioned problems is the missing puzzle and the essential need of these engines. In order to achieve an engine that provides the highest torque, power, acceleration and performance with minimum fuel, it is necessary that the fuel explosion takes place in the best way in the combustion chamber. There are three main factors for this to occur: 1. Fuel, 2. Spark and 3. Air. Each of these factors has a very broad category. For example, concerning the fuel, we can refer to octane, injection ratio, injection time, injection angle, gasoline direct injection (GDI) or indirect injection, etc., and concerning spark, one can refer to spark voltage, spark power, number of sparks, spark time, spark advance, the concentration of fuel near the spark, the type of spark plug, the gap of the spark plug, etc., for each of which many measures have been provided by experts to improve performance. In the following, the work that has been done for more than 12 years on the topic of air and engine breathing (inhalation and exhalation) during many efforts and repeated long-term scientific, practical and field tests will be explained in detail. Regarding the air intake to internal combustion engines, the following factors play an effective and decisive role on an explosion that occurs in the combustion chamber: 1. The amount of kinetic energy of the intake air molecules, 2. The turbulence of the intake air flow, 3. Friction and the decrease in the intensity of the air flow in the passing channels, 4. The balanced mixing of air and fuel, 5. The amount and flow rate of the intake air, an 6-. The flame propagation speed. The invention designed to achieve the aforementioned purposes uses the kinetic theory of gas molecules (Kinetic theory), which includes translational, rotational and vibrational movements in liquids and gases. Also, by applying and using this theory and increasing the kinetic energy of translational, rotational, and vibrational motion, and creating a disturbance in the flow of air intake into the engine (cold air) through the ventilation channel and after passing through the air filter, as well as the smoke from combustion (hot air) that leaves the engine through the exhaust, while increasing the speed and the flow of air entering the engine, the wear of air molecules with the walls of the passing channels, which is the main cause of the decrease in the intensity of the air flow, is reduced. Moreover, the strong vibrational movements of the air flow exposed to fuel spray causes a balanced mixing of fuel and air and increases the speed of flame propagation and creates a strong explosion because thin and thick chokes outside the fuel range in the combustion chamber are the main cause of incomplete combustion and emission production.

Two cars have been tuned with this invention. The cars are ready for any test.
According to the growing trend of this invention during 12 years of effort and testing, the latest achievements are as follows:

a- Mitsubishi Pajero Year of production 2014, 6G74 engine with a volume of 3497 CC. (This car is reinforced at the air inlet to the engine with this invention, that is, it has been strengthened by about 40% to 50%, According to the manufacturer, the acceleration from 0-100 km is 12.6 seconds, while the acceleration from 0-100 km in the tuned car is about 10.1 seconds (The test was performed on the street, in standard conditions it definitely gives better results, 100-0 acceleration video is available)).

Conclusion
Based on the studies, researches and tests conducted, it can be concluded that with a small cost, it is possible to save fuel consumption, which will quickly return the cost, and reduce the level of pollutants, which is good news for the citizens and the polluted air of the cities. A 25% reduction in fuel consumption while reducing car maintenance costs preserves national reserves and with 33% increase in initial acceleration, you can enjoy the pleasure of driving cars with modern technical specifications. Since cars are the main cause of air pollution in big cities, the reduction of 50% of carbon monoxide and 78% of hydrocarbons can be a big event in the polluted air of cities, and considering that the operation of a private car is about 20000 kilometers per year, 25% reduction in fuel consumption means saving 370 liters of gasoline for each private car per year, which is about 1000 liters per year for public cars. The above results are very tempting to preserve the environment and national reserves.
