The most important type of prime mover is the internal-combustion engine. Most of the engines of this type use liquids as their fuel, but some burn gas from manufactured or natural sources. The two most common fuels used are gasoline and diesel or fuel oil. In the internal-combustion piston engine, the fuel is forced into the space between the cylinder head and the piston. The space between the cylinder head and the piston is called the combustion chamber. The size of this combustion chamber depends on the position of the piston.
There are several types of such engines, depending upon cycle, location of parts, and other items. A partial designation of engine types could be as follows:
type of fuel burned: gasoline, kerosene, fuel oils, gases;
method of cooling: liquid or gas (air);
arrangement of cylinders;
valve location;
cycle: four-stroke and two-stroke;
type of valves;
ignition: spark or compression;
moving parts: piston or blade (turbine);
compression: low, medium, high.
One of the most important engine designation is by the cycle used. The usual outboard boat engine is of the two-stroke cycle. The usual tractor engine and all known automobile engines are of the four-stroke type.
The cycles of the four-stroke engine are as follows: intake, one valve open; compression, both valves closed; burning or combustion, both valves closed; exhaust, one valve open.
Thus one cycle of four events with four strokes of the piston has been completed (ignition could be a fifth event).
Read and translate the following words and word combinations:
an internal-combustion piston engine, a combustion chamber, four-stroke cycle, two-stroke cycle, gasoline, fuel oil, method of cooling, liquid, a moving part, intake, exhaust, a valve location, type of valves, ignition, a spark, compression, a piston, engine designation, a cylinder head, an outboard boat engine, items, burning, to burn.

ENGINES
There are external-combustion engines and internal-combustion engines. In an external - combustion engine, the fuel is burned outside the engine. The steam engine and steam turbine are good examples of an external-combustion engine. Today the internal-combustion engine has been displacing the steam locomotive engine. The internal-combustion engine has undergone numerous changes in design and construction. But its basic principle of operation has not changed. Engines operate on the four-stroke-cycle and on the two-stroke-cycle principles. Modern engines have some changes and improvements. They are:
Increased compression ratios.
Improved valve timing.
Better balance of moving parts.
Better mixing and distribution of fuel.
More accurate timing of fuel charge ignition.
Modern engines can operate at extremely high speed. They have some improvements in materials and methods. Modern engines are powerful, highly efficient, have lightweight. Engines vary in size, design. However, they have certain parts that perform similar functions. The various parts of the engines are as follows: a cylinder block, a cylinder head, pistons, piston rings, piston pins, a connecting rod, a crankshaft, engine bearings, valves, valve lifters, and manifolds.
