1. Review of diesel engine engine engine 2. Review of hydrogen - Essay ExampleThe invention of Diesel was financed by M. A. N. of Augsburg (Mathur and Sharma 2000).Diesel has a boiling range of about 180C to 300C. It is widely used because it is cheap and has better thermal efficiency. Today Diesel is produced in three ways Petroleum Diesel, celluloid Diesel and BioDiesel.1. Petroleum Diesel Petroleum diesel is also called as Fossil Diesel. This diesel is produced from fractional distillation of crude oil. The supply of petroleum diesel is fast depleting and hence the search for other types is becoming all the more important.2. Synthetic Diesel Synthetic diesel is made by processing pictorial gas through a technology which converts the natural gas into Synthetic Diesel. Synthetic diesel is free from sulphur and provides numerous other environmental benefits over petroleum diesel. Synthetic diesel is cleaner, cleaner-burning and rump be formulated for superior cold weather pe rformance. The pursual diagram shows the emission reductions compared to typical California diesel3. Biodiesel Biodiesel is a renewable diesel fuel substitute. It can be made from a variety of natural oils and fats. Biodiesel is made by chemically combining all natural oil or fat with an alcohol such as methanol or ethanol. wood alcohol has been the most commonly used alcohol in the commercial production of biodiesel (National Renewable Energy Laboratory, whitethorn 1998).The diesel cycle is the theoretical cycle for slow speed densification-ignition or diesel engines. In a diesel cycle the conflagrate is added at constant pressure. The pressure drop at the end of refinement is still at constant volume. This cycle is shown in the following T-s diagram.The process 1-2 is reversible adiabatic (isentropic) compression of air. Heat is then added at constant pressure, represented by 2-3. In actual engine heat addition takes place in the form of injection of fuel which self-ignites du e to in high spirits temperature caused by high compression
