Aircraft engine An aircraft engine is the component of the propulsion system for an aircraft that generates mechanical power. Aircraft engines are almost always either lightweight piston engines or gas turbines. Turbine-powered Turboprop A turboprop engine is a type of turbine engine which drives an aircraft propeller using a reduction gear. The gas turbine is designed specifically for this application‚ with almost all of its output being used to drive the propeller. The engine’sexhaust gases do

AIR-STANDARD ANALYSIS: INTERNAL COMBUSTION ENGINES Air-standard analysis treats the fluid flow through the entire engine as air and approxi¬mates air as an ideal gas. In a real engine inlet flow may be all air‚ or it may be mixed‚ up with 7% fuel‚ either gaseous or as liquid droplets‚ or both. In air-standard analysis‚ even if all fluid in an engine cycle were air‚ some error would be introduced by assuming it to be an ideal gas with constant specific heats. At the low pressures of inlet and

Automotive engine Engines are desinged to be two strokes or four strokes of a piston that moves up and down in a cylinder. Generally‚ the automotive engine uses four strokes to convert chemical energy to mechanical energy through combustion of gasoline or similar hydrocarbon fuel. The heat produced is converted into mechanical work by pushing the piston down in the cylinder. A connecting rod attached to the piston transfers this energy to a rotating crankshaft Engines having from 1

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 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
