Home Dictionary Name: internal combustionInternal combustion
Designating or pertaining to any engine called an Internal combustion engine in which the heat or pressure energy necessary to produce motion is developed in the engine cylinder as by the explosion of a gas and not in a separate chamber as in a steam engine boiler The gas used may be a fixed gas or one derived from alcohol ether gasoline petrol naphtha oil petroleum etc There are three main classes 1 gas engines proper using fixed gases as coal blast furnace or producer gas 2 engines using the vapor of a volatile fluid as the typical gasoline petrol engine 3 oil engines using either an atomized spray or the vapor produced by heat of a comparatively heavy oil as petroleum or kerosene In all of these the gas is mixed with a definite amount of air the charge is composed in the cylinder and is then exploded either by a flame of gas flame ignition now little used by a hot tube tube ignition or the like by an electric spark electric ignition the usual method is gasoline engines or by the hea...
Otto cycle
A four stroke cycle for internal combustion engines consisting of the following operations First stroke suction into cylinder of explosive charge as of gas and air second stroke compression ignition and explosion of this charge third stroke the working stroke expansion of the gases fourth stroke expulsion of the products of combustion from the cylinder This is the cycle invented by Beau de Rochas in 1862 and applied by Dr Otto in 1877 in the Otto Crossley gas engine the first commercially successful internal combustion engine made...

Semi Diesel
Designating an internal combustion engine of a type resembling the Diesel engine in using as fuel heavy oil which is injected in a spray just before the end of the compression stroke and is fired without electrical ignition The fuel is sprayed into an iron box called a hot bulb or hot pot opening into the combustion chamber and heated for ignition by a blast lamp until the engine is running when it is ordinarily kept red hot by the heat of combustion...

Diesel
A type of internal combustion engine in which the air drawn in by the suction stroke is so highly compressed that the heat generated ignites the fuel usually a heavy oil the fuel being automatically sprayed into the cylinder under pressure The Diesel engine has a very high thermal efficiency...
