What is a Turbocharger? A Turbocharger is a Turbine driven device which is used to increase the volumetric efficiency of an internal combustion engine. It takes power from exhaust gases coming from an engine and use that power to suck fresh air from the atmosphere and supply it to the engine for combustion. Why we… Read More »
There are several parameters which are used to determine the performance of an engine which are generally known as Engine Performance Parameters. These parameters include several efficiencies, ratios of different values etc. let us discuss each of these parameters one by one. Indicated thermal efficiency (η ith) Indicated thermal efficiency is the ratio of indicated… Read More »
Four Stroke Engines The engines with are generally used in our car or bike is a four stroke engines. Earlier two stroke engines were also used in scooters and motorcycles but now they are almost obsolete. For successful operation, an Engine has to complete a sequence of operations in a cycle. In case of four… Read More »
Cylinder Block The cylinders of a multi-cylinder engine are cast as a whole and it is called cylinder block. The cylinder block is the main supporting structure of an engine. Cylinder block is mounted with cylinder head at top and crankcase at the bottom. Both cylinder head and crankcase are attached to the cylinder block… Read More »
On the basis of place of actual combustion of the fuel, engines are categorized into internal and external combustion engines. In internal combustion engine fuel burns inside the engine, while in external combustion engine actual burning of fuel takes place outside the engine and heat is carried to the engine with the help of working… Read More »
To understand Internal combustion engines completely one has to be well versed with engine classification. Internal combustion engines can be classified on the basis of several grounds. Some of the most popular grounds of IC engines classification are discussed here in detail. Classification of IC engines based on type of fuel used 1. Engines using… Read More »
Abbreviations used SI : Spark Ignition, CI: Compression Ignition Many people generally find it difficult to differentiate between SI and CI engines. To solve this problem we came with an exhaustive comparison between SI and CI engines (spark ignition vs compression ignition). This comparison has been drawn in the form of a table to make it… Read More »
Reciprocating internal combustion is one of the most widely used engines around the world. This is the same engine which is used in our cars and bikes. As like every other heat engine, there are some advantages and some Disadvantages of reciprocating internal combustion engines. Advantages of reciprocating internal combustion engines Unlike steam turbine no… Read More »
What is a Heat Engine? Before moving on to the heat engines (Classification of Heat Engines), let us first understand what is an engine. An Engine is a device which converts one form of energy into another form. Engines can further be divided into two types i.e. combustion engines and non-combustion engines. Examples of non-combustion… Read More »
What is Compressed Natural Gas? Natural gas is a fossil fuel which is usually formed in the Earth along with petroleum. Its main constituent is methane. It also contains small quantities of Ethane and Propane. It is liquefied by compression. CNG is used as a fuel in automobiles, houses and factories. It is also used… Read More »
