Diesel has a mark as traditional hydrocarbon structure as conventional fuels. H2O2 freshly reported as fuel combustion enhancer and to be a low-emission high-quality oxidizer. Consequently, this article discusses the influence of hydrogen peroxide (H2O2) combination with diesel in different percentages for combustion and COx, SOx and NOx emissions. A comparative study will be carried out to analyze the effect on direct insertion of H2O2 into the combustion chamber with that of induction through the inlet manifold for dual fueling. Percentage of H2O2 substitute varied from 10% to 15%, at the same time reducing the diesel percentages. Since the extra atom of oxygen of H2O2 is in suspension in water and in an unstable condition wherein the oxygen is eager to escape unless held under slight pressure in the container in which it is stored. The addition of H2O2 at various wt. percentage concentrations in to diesel at mixture (diesel/H2O2) form will be used for the experiments and measurements can be made to study the performance, combustion, and emissions characteristics. The performance of in starting from lean diesel until obtaining a better composition can reduce the diesel fuel consumption. The objective of this study is that the addition of hydrogen peroxide can extend the lean operation limit, improve the lean burn ability, decrease burn duration and controlling the exhaust emission by reducing green house gases.

Diesel fuel in general is any fuel used in diesel engines. The most common is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel, are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is increasingly called petrodiesel. Ultra-low sulfur diesel (ULSD) is a standard for defining diesel fuel with substantially lowered sulfur contents. As of 2007, almost every diesel fuel available in America and Europe is the ULSD type. In the UK, diesel is commonly abbreviated DERV, standing for Diesel Engined Road Vehicle (fuel).  Diesel engines are a type of internal combustion engine. Rudolf Diesel originally designed the diesel engine to use coal dust as a fuel. He also experimented with various oils, including some vegetable oils, such as speanut oil, which was used to power the engines which he exhibited at the 1900 Paris Exposition and the 1911 World's Fair in Paris.Petroleum diesel, also called petrodiesel, or fossil diesel is produced from the fractional distillation of crude oil between 200 °C (392 °F) and 350 °C (662 °F) at atmospheric pressure, resulting in a mixture of carbon chains that typically contain between 8 and 21 carbon atoms per molecule. The density of petroleum diesel is about 0.85 kg/l (7.09 lb/US gal), about 18% more than petrol (gasoline), which has a density of about 0.72 kg/l (6.01 lb/US gal). When burnt, diesel typically releases about 38.6 MJ/l (138,700 BTU/US gal), whereas gasoline releases 34.9 MJ/l (125,000 BTU/US gal), 10% less  by energy density, but 45.41 MJ/kg and 48.47 MJ/kg, 6.7% more by specific energy. Diesel is generally simpler to refine from petroleum than gasoline. The price of diesel traditionally rises during colder months as demand for heating oil rises, which is refined in much the same way. Because of recent changes in fuel quality regulations, additional refining is required to remove sulfur, which contributes to a sometimes-higher cost. Petroleum-derived diesel is composed of about 75% saturated hydrocarbons (primarily paraffin’s...
