Modern web search engines are highly intricate software systems that employ technology that has evolved over the years. There are a number of sub-categories of search engine software that are separately applicable to specific ’browsing’ needs. These include web search engines (e.g. Google)‚ database or structured data search engines (e.g. Dieselpoint)‚ and mixed search engines or enterprise search. The more prevalent search engines‚ such as Google and Yahoo!‚ utilize hundreds of thousands computers

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

aspirated engines versus forced induction engines. Among mechanics and race car drives this subject has been debated since the creation of the forced induction engine. The principle behind the forced induction engine is the use of different types of air compressor called turbochargers to compress the air entering the engine‚ this unit is attached to a naturally aspirated engine and uses the exhaust gases to spin a turbine to compress the air going into the engine.The naturally aspirated engine draws

History of Caterpillar Engines The start of Caterpillar engines actually begins before Caterpillar was even a company. The history began back in the late1800’s when Daniel Best and Benjamin Holt were experimenting with various forms of steam tractors used for farming. The two competed with each other to gain the lead in the farm equipment industry. Throughout the late 1800’s and early 1900’s Holt and Best continued to build both steam and gas tractors. In 1908 Best sold his company to Holt. In 1925

This 300 N cryogenic propellant engine has a vacuum Isp of 415 seconds - the highest value ever achieved in Europe for an engine of such small size. Being pressure-fed‚ the engine assembly is relatively simple and avoids the need for a turbo-pump. The thrust chamber and throat region of the engine are regeneratively cooled using hydrogen propellant. The nozzle extension is radiation cooled. The engine incorporates a splash-plate injector having a star shaped configuration. Ignition and subsequent
