  • Diesel Engines and the Evolution of Diesel as Fuel

    A diesel engine (also known as a compression-ignition engine and sometimes capitalized as Diesel engine) is an internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel‚ which is injected into the combustion chamber. This is in contrast to spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline)‚ which uses a spark plug to ignite an air-fuel mixture. The engine was developed by Rudolf Diesel

  • Diesel Engines

    Diesel Engines Diesel engines are everywhere; they are used in all sorts of vehicle platforms. From Volkswagen Jetta’s‚ to big eighteen wheel tractor trailer trucks. They provide more torque then a regular gasoline engine because of the long stroke of the piston. Most diesel engines make peak torque at very low rpm. Diesel engines do not have spark plugs. They develop combustion by heating up the air going into the cylinder‚ while the air is heated the fuel injector sprays into the bowl of

  • Fuel Injection in Diesel Engines

    Fuel injection in diesel engines [edit] Mechanical and electronic injection Older engines make use of a mechanical fuel pump and valve assembly which is driven by the engine crankshaft‚ usually via the timing belt or chain. These engines use simple injectors which are basically very precise spring-loaded valves which will open and close at a specific fuel pressure. The pump assembly consists of a pump which pressurizes the fuel‚ and a disc-shaped valve which rotates at half crankshaft speed

  • Diesel Engine

    Diesel Engine Heat engines are sometimes referred to as being motors. Actually‚ a motor converts one form of energy into useful work without the intentional production of heat‚ such as an electric motor. A device which burns fuel creating heat to perform work is a heat engine. Heat engines can be classified as external combustion‚ such as steam boiler‚ or internal combustion (IC). They can further be divided into the spark ignited (SI) engine or the compression ignited engine (CI). The compression

    The Diesel Engine Diesel engines are very similar to the gasoline engine you may find in a car. They both are internal combustion engines‚ have a four stroke cycle‚ and convert chemical energy from fuel into mechanical energy. However‚ the manner in which the combustion stroke is attained sets these two engines apart‚ and although a seemingly meaningless change‚ a large change in efficiency results. (Diesel Engines vs. Gasoline Engines) The diesel engine was invented by Rudolf Diesel in 1892

  • Diesel and Gasoline Engines

    MECHANICAL STRUCTURE Both being internal combustion type diesel and gasoline engines can be considered as similar. Simply‚ both engines converts chemical energy into mechanical one by burning fuel. In combustion engines the combustion (explosion of fuel) occurs at combustion chamber with ‚ generally‚ help of oxidizer (air‚ another fluid‚ etc.). The output‚ high heat and pressure of the burning process is transfered to other components of the engines which expose pressure as a mechanical energy. Some of

  • Diesel and Petrol Engines

    Let’s start with the basics. Aside from additives such as ethanol‚ which is made from corn‚ the gasoline and diesel fuel commonly used today derive from the same source--crude oil. Although they share the same parentage (just like motor oil‚ some plastics‚ and Velveeta)‚ they have very different properties. Gasoline is often thought of as being a single chemical‚ but it’s actually a complex mixture of hydrocarbons that generally have 4 to 12 carbon atoms in their molecules. In the case of gasoline
