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

Web Search Engines Typically‚ Web search engines work by sending out a spider to fetch as many documents as possible. Another program‚ called an indexer‚ then reads these documents and creates an index based on the words contained in each document. Each search engine uses a proprietary algorithm to create its indices such that‚ ideally‚ only meaningful results are returned for each query. Sites that let you search multiple indexes simultaneously include: • Yahoo (http://www.yahoo.com) • search

AIR DRIVEN ENGINE ABSTRACT: The Air Driven Engine is an eco-friendly engine which operates with compressed air. An Air Driven Engine uses the expansion of compressed air to drive the pistons of an engine An Air Driven Engine is a pneumatic actuator that creates useful work by expanding compressed air. There is no mixing of fuel with air as there is no combustion. An Air Driven Engine makes use of Compressed Air Technology for its operation The Compressed Air Technology

1. CYLINDER BLOCK- The engine block is the linchpin of vehicles which run on internal combustion‚ providing the powerhouse for the vehicle. EX: A General Motors in-line‚ 6-cylinder block- the entire unit is a one-piece casting of alloy cast iron. Transverse members provide rigidity and strength‚ ensuring alignment of the bores and bearings under all loads. Function- In the bore of cylinder the fresh charge of air-fuel mixture is ignited‚ compressed by piston and expanded to give power to piston

HEAT ENGINE WORKING CYCLES An engine is a device which transforms one form of energy into another form. However‚ while transforming energy from one form to another form‚ the efficiency of conversion plays an important role. Normally‚ most of the engines convert thermal energy to mechanical work and therefore they are called ‘heat engines’. Heat engine is a device which transforms the chemical energy of a fuel into thermal energy and utilizes this thermal energy to perform useful work. Depending
