Two-stroke engines have certain advantages. They produce more power and more compact than the four-stroke engine, and they are lightweight and less costly. On the other hand, some fuel gets wasted in a two-stroke engine, decreasing its efficiency.
In two-stroke engines, the cycle of operations of the engine are completed by two strokes of the piston inside the cylinder. Two-stroke petrol engines and diesel engines work in the same way. The cycle of operation of two-stroke engines will be further described.
The cycle of operations of the four-stroke compression ignition (CI) engine are completed in four strokes of the piston inside the cylinder. These four-strokes are: suction, compression, expansion or power, and exhaust. During these four strokes two revolutions of the crankshaft are produced.
In a four-stroke spark ignition (SI) engine the cycle of operations of the engine are completed in strokes of the piston inside the cylinder. The four strokes of the piston are: suction, compression, expansion or power, and exhaust. Each stroke will be described in detail.
Manufacturing of any structure, product or part actually begins in the human mind. There is a way to project that image out from the intangible realms of the mind into the more mundane realms of matter. It combines art and science and is known as engineering drawing as we shall learn here.
The Spark Ignition (SI) engines work on the principle of cycle of operations invented by Nicolaus A. Otto in the year 1876. The Compression Ignition (CI) engines work on the principle founded by Rudolf Diesel in the year 1892.
Almost all people use vehicles, but they are not aware of the meaning of general terms related to the engine. This articles defines some of the popular terms related to the vehicle’s engine.
There are two main types of IC engines: spark ignition (SI) engines (petrol or gasoline engine) and compression ignition (CI) or diesel engine. Both these engines are further classified as 2-stroke and 4-stroke engine.
What do you do when you want to filter some impurities from the oil in your can which, over the course of time, may be caused by soil, dust, water or other immiscible materials? You may over-simplify by using a sieve filter but see how large quantities of oil are purified.
(ASHRAE) has been responsible for promoting research and development in the heating, refrigerating and air-conditioning field. It has also developed a number of codes and standards for testing, designing and operation of HVAC.
