Literally minutes before the plane was to take off, the engine was even ticking over, Levine, who had been at the airfield with his wife to send off Chamberlin, made "as if to close the cabin door [but instead] suddenly climbed in to occupy the second seat… and without a single word of explanation either to his wife or to officials on the ...
The engine immediately started ticking over. We both stood next to the engine and switched it up to "release exhaust to chamber" so that the gases were channelled into the chamber. On the instigation of the chemist I revved up the engine, which meant that no extra gas had to be added later. After about ten minutes the thirty to forty women were ...
1816 – Robert Stirling invented his hot air Stirling engine, and what we now call a "regenerator". [5] [6] 1821 – Michael Faraday builds an electricity-powered motor. 1824 – Nicolas Léonard Sadi Carnot first publishes that the efficiency of a heat engine depends on the temperature difference between an engine and its environment.
Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
Overspeed is a condition in which an engine is allowed or forced to turn beyond its design limit. The consequences of running an engine too fast vary by engine type and model and depend upon several factors, the most important of which are the duration of the overspeed and the speed attained.
A "twingle" is a four-stroke twin-cylinder engine with an altered firing order designed to give power pulses similar to a single-cylinder four-stroke engine. Inline twins with a 360° crankpin offset or flat-twins can be easily converted into twingles by firing both of the cylinders at the same time and installing a camshaft or camshafts that ...
Improvements made by John Smeaton to the Newcomen engine increased the efficiency to over 1%. James Watt made several improvements to the Newcomen engine, the most significant of which was the external condenser, which prevented the cooling water from cooling the cylinder. Watt's engine operated with steam at slightly above atmospheric pressure.
In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.
