Industry and Traffic emissions – such as from trucks, buses, and automobiles are the biggest source of air pollution.
Airborne by-products from vehicle exhaust systems cause air pollution and are a major ingredient in the creation of smog in some large cities. The major culprits from transportation sources are carbon monoxide (CO), nitrogen oxides (NO and NOx), volatile organic compounds, sulfur dioxide, and hydrocarbons. (Hydrocarbons are the main components of petroleum fuels such as gasoline and diesel fuel.) These molecules react with sunlight, heat, ammonia, moisture, and other compounds to form the noxious vapors, ground level ozone, and particles that comprise smog.
The most common combustion engines are gasoline (petrol) engines and diesel engines.
Gasoline (petrol) engines
Modern gasoline engines have a maximum thermal efficiency of about 25% to 30% when used to power a car. In other words, even when the engine is operating at its point of maximum thermal efficiency, of the total heat energy released by the gasoline consumed, about 70-75% is rejected as heat without being turned into useful work, i.e. turning the crankshaft. Approximately half of this rejected heat is carried away by the exhaust gases, and half passes through the cylinder walls or cylinder head into the engine cooling system, and is passed to the atmosphere via the cooling system radiator. Some of the work generated is also lost as friction, noise, air turbulence, and work used to turn engine equipment and appliances such as water and oil pumps and the electrical generator, leaving only about 25-30% of the energy released by the fuel consumed available to move the vehicle.
At idle, the thermal efficiency is zero, since no usable work is being drawn from the engine. At low speeds, gasoline engines suffer efficiency losses at small throttle openings from the high turbulence and frictional (head) loss when the incoming air must fight its way around the nearly closed throttle; diesel engines do not suffer this loss because the incoming air is not throttled. At high speeds, efficiency in both types of engine is reduced by pumping and mechanical frictional losses, and the shorter period within which combustion has to take place. Engine efficiency peaks in most applications at around 75% of rated engine power, which is also the range of greatest engine torque (e.g. in most modern passenger automobile engines with a redline of about 6,000 RPM, maximum torque is obtained at about 4,500 RPM, and maximum engine power is obtained at about 6,000 RPM). At all other combinations of engine speed and torque, the thermal efficiency is less than this maximum.
A gasoline engine burns a mix of gasoline and air, consisting of a range of about twelve to eighteen parts (by weight) of air to one part of fuel (by weight). A mixture with a 14.7:1 air/fuel ratio is said to be stoichiometric, that is when burned, 100% of the fuel and the oxygen are consumed. Mixtures with slightly less fuel, called lean burn are more efficient. The combustion is a reaction which uses the air’s oxygen content to combine with the fuel, which is a mixture of several hydrocarbons, resulting in water vapor, carbon dioxide, and sometimes carbon monoxide and partially burned hydrocarbons. In addition, at high temperatures the oxygen tends to combine with nitrogen, forming oxides of nitrogen(usually referred to as NOx, since the number of oxygen atoms in the compound can vary, thus the “X” subscript). This mixture, along with the unused nitrogen and other trace atmospheric elements, is what we see in the exhaust.
In the past 3–4 years, GDI (Gasoline Direct Injection) increased the efficiency of the engines equipped with this fueling system up to 35%. Currently, the technology is available in a wide variety of vehicles ranging from less expensive cars produced by Mazda, Ford and Chevrolet to more expensive cars produced by BMW, Mercedes-Benz, and Volkswagen Auto Group.
Engines using the Diesel cycle are usually more efficient, although the Diesel cycle itself is less efficient at equal compression ratios. Since diesel engines use much higher compression ratios (the heat of compression is used to ignite the slow-burning diesel fuel), that higher ratio more to air pumping losses within the engine.
Modern turbo-diesel engines are using electronically controlled, common-rail fuel injection, that increases the efficiency up to 50% with the help of geometrically variable turbo-charging system; this also increases the engines’ torque at low engine speeds (1200-1800RPM).
The low efficiency and high release of polluting exhaust gas emissions is also the reason why combustion engines pollute fast. Carbon deposits on piston heads, valves, piston rings and EGR system not only reduce the engine efficiency, it also contributes to higher fuel consumption and even higher levels of harmful emissions. It is therefore important to use specialized cleaners regularly to keep your combustion system clean.
Green Mile Solutions has developed 2 special cleaners,
1. Maxxlube® Intake Cleaner, an aerosol to be applied by the engine air intake
2. Maxxlube® Instant Cleaner, a fast & effective fuel additive
Both products are suitable for as well gasoline as diesel engines to clean the combustions systems and bring the engine back to factory standards.
By improved lubrication also a reduction in fuel consumption and harmful emissions can be achieved. Less friction results in a better fuel economy which as a result leads in emission reduction. Today’s engine oils are of good quality. Engine Oil is a mixture of a base oil and additives. The quality and performance of these additives determine the cost price of the oil. Where engine oil manufacturers stop for cost price reasons… we went on with as result a Multi Active Ceramic Engine Oil Addive to upgrade your oil to the highest possible level. This additive is called Maxxlube Ceramic Engine Protector
