List of Steam Boilers: Types, Parts and Operation! 1. Lancashire Boiler: A Lancashire boiler was first used by about 1840 and is a development of the Cornish pattern. They are still used in considerable numbers in industry, principally on account of their simplicity of design together with reliability and freedom from maintenance costs for repairs and tube renewals which are [...]
In this article we will discuss about the construction and working of various boilers with diagram. Construction of Lancashire Boilers: The modern Lancashire boilers are dish ended and welded pattern at least for higher pressures, instead of the older flat ended riveted type. The dish ended construction reduces the tendency of bulging of the end plates and therefore it does [...]
The testing of I.C. Engines is the process of assessing the performance and operation of the engine in the efficient manner. There are various parameters which can be measured for testing of I.C. Engines. The testing of the engine is necessary for understanding the efficient operation of the engine and the engine components. The operation of the new engine depends [...]
In this article we will discuss about the carburetor and components of carburetor. The carburetor is provided with additional devices to perform proper operation. The devices used are: 1. Main Metering System 2. Idling System 3. Starting System Or Choke 4. Compensating Jet 5. Acceleration Pump 6. Economizer. Type # 1. Main Metering System: The main metering system consists of [...]
In this article we will discuss about the testing of lubricants for IC engines. The selection of a suitable lubricant for a particular purpose requires knowledge of its properties in the working condition as well as the performance of these properties under conditions of service. Experimental Determination of Lubricant Properties: Properties can be experimentally determined by the following tests: Tests [...]
In this article we will discuss about the working of four stroke and two stroke IC engines. Four Stroke Cycle Engine: Principle: In IC Engines the following events take place in the cyclic order: (1) The quantity of air or mixture of air and fuel must be admitted in the engine cylinder. It is generally known as the charge. (2) [...]
In this article we will discuss about the IC engine:- 1. Notes on Internal Combustion Engine 2. Basic Operation of IC Engine 3. Classification 4. Construction 5. Supercharging 6. Firing Order 7. Methods of Starting IC Engines 8. Governing. Contents: Notes on Internal Combustion Engine Basic Operation of IC Engine Classification of IC Engines Construction of IC Engines Supercharging of [...]
Lubrication Systems and Methods of Lubrication used in IC Engine! Introduction to Lubrication in I.C. Engine: The machine parts which have relative motion rub against each other. The rubbing surfaces are never perfectly smooth, even when they are highly polished. If they are observed under a microscope, small depressions and elevations can be seen. These depressions and elevations get interlocked [...]
In this article we will discuss about the Otto Cycle and Diesel Cycle of IC engine. The question arises of these engines, which are most efficient and what are the factors that impose limitation on the maximum efficiency. Sadi Carnot was the first scientist to study this problem and he found that the maximum possible efficiency of an engine, working [...]
Fuel Supply System in Diesel Engine! Introduction to Fuel Supply System for CI Engines: The fuel supply system of a diesel engine can be called as the heart of the engine, since the engine performance directly depends upon the proper functioning of this system—which must supply, meter, inject and atomize the fuel. Fuel injection systems are manufactured with great accuracy, [...]
