2. Bourke engine - Wikipedia

   en.wikipedia.org/wiki/Bourke_engine

   A test of a 30 cubic inch Vaux engine, built by a close associate of Bourke, gave a fuel consumption of 1.48 lb/(bhp hr), or 0.7 (lb/hr)/hp at maximum power. [6] Power to weight - The Silver Eagle was claimed to produce 25 hp from 45 lb, or a power-to-weight ratio of 0.55 hp/lb. The larger 140 cubic inch engine was good for 120 hp from 125 lb ...

3. Reciprocating compressor - Wikipedia

   en.wikipedia.org/wiki/Reciprocating_compressor

   A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure. [ 1 ] [ 2 ] Pressures of up to 5,000 psig are commonly produced by multistage reciprocating compressors.

4. Indicator diagram - Wikipedia

   en.wikipedia.org/wiki/Indicator_diagram

   An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or compressor, cycle. The indicator diagram is used to calculate the work done and the power produced in an engine cylinder [2] or used in a compressor cylinder.

5. Variable-speed air compressor - Wikipedia

   en.wikipedia.org/wiki/Variable-speed_air_compressor

   For example, 10–12% of all power generated in the UK is dedicated to the production of compressed air and a portion of this power is wasted energy. Large electrical cost savings can be achieved by installing a variable speed drive compressor in place of an existing rotary screw or piston machine.

6. Compressor map - Wikipedia

   en.wikipedia.org/wiki/Compressor_map

   These effects are caused by the sluggish response of the spool (i.e. inertia effects) to rapid changes in engine fuel flow. Compressor surge is a particular problem during slam-accelerations and can be overcome by suitable adjustments to the fueling schedule and/or use of blow-off (bleeding air off the compressor, for handling purposes).

7. Compressor characteristic - Wikipedia

   en.wikipedia.org/wiki/Compressor_characteristic

   Compressor characteristic is a mathematical curve that shows the behaviour of a fluid going through a dynamic compressor. It shows changes in fluid pressure , temperature , entropy , flow rate etc.) with the compressor operating at different speeds.
