The internal combustion engine is an engine in which the burning of a fuel occurs in a confined space called a combustion chamber. This exothermic reaction of a fuel with an oxidizer creates gases of high temperature and pressure, which are permitted to expand. The defining feature of an internal combustion engine is that useful work is performed by the expanding hot gases acting directly to cause movement, for example by acting on pistons, rotors, or even by pressing on and moving the entire engine itself.

This contrasts with external combu ....etc

In the history of internal combustion engine development, hydrogen has been considered at several phases as a substitute to hydrocarbon-based fuels. Starting from
the 70 s, there have been several attempts to convert engines for hydrogen operation.
Together with the development in gas injector technology, it has become possible to
control precisely the injection of hydrogen for safe operation. Since the fuel cell needs
certain improvements before it is widely used in vehicles, the conventional internal combustion engine is to play an impor ....etc

INTRODUCTION
Internal combustion (IC) engines are used in a variety of stationary applications ranging from power generation to inert gas production. Both spark ignition and compression ignition engines can be found. Depending on the application, stationary IC engines range in size from relatively small ( 50 hp) for agricultural irrigation purposes to thousands of horsepower for power generation. Often when used for power generation, several large engines will be used in parallel to meet the load requirements. A variety of fuels ....etc

Abstract

A hydrogen internal combustion engine vehicle (HICEV) is a type of hydrogen vehicle using an internal combustion engine.Hydrogen internal combustion engine vehicles are different from hydrogen fuel cell vehicles (which use electrochemical conversion of hydrogen rather than combustion); the hydrogen internal combustion engine is simply a modified version of the traditional gasoline-powered internal combustion engine. ....etc

CLASSIFICATION OF INTERNAL COMBUSTION ENGINES

I.C.ENGINES! DO WE REALLY NEED EM?

I have always considered that the substitution of the Internal Combustion Engine for the horse marked a very gloomy milestone in the progress of mankind.
-Winston Churchill

If all the perverted ingenuity which was put into making automobiles had only gone into improving the breed of horses, we might be a lot better off today.
