We all know an engine converts one form of energy to another form, which is usually a work. The type of engines which are generally used to move vehicles are combustion engines. Combustion engines are the engines which burn fuel to obtain energy and they convert that energy into work. Combustion engines are of two types.… Read More »
What is a Supercharger Before learning about supercharger let us first understand the factors on which power output of an engine depends. The power output of a naturally aspirated engine depends on following things. Amount of air inducted into the system Extent of utilization of inducted air Speed of the engine Quality of fuel used… Read More »
Engine Cooling System While running, an engine continuously produces heat and converts it into power. This heat is derived by burning fuel in the engine. But as we all know, there is no engine in the world which is 100% efficient. There is always some amount of heat energy which gets wasted. If we do… Read More »
Ignition System For burning any fuel we need two things, oxygen and heat. Fuels which has a low self ignition temperature can even be burnt by applying high pressure like, Diesel. But the case of petrol or gasoline is different. Here we need an ignition system to ignite the fuel. In spark ignition engines, compression… Read More »
Electronic Fuel Injection (EFI) System Electronic fuel injection (EFI) system is used both in gasoline and diesel engines. There are many problems with the carburetors used for preparing charge in the gasoline engines. Some of them are Non-uniform distribution of fuel in a multi-cylinder engine. Poor breathing capacity (volumetric efficiency) of the engine. Problem of… Read More »
Fuel injection system Fuel injection system is the very important part of the Compression Ignition (CI) engine. The performance of an engine viz. power output, economy etc. is largely dependent on the fuel injection system. The injection system has to perform important duty initiating and controlling the combustion process. What is the difference between carburetion… Read More »
Liquefied Petroleum Gas All of you must be knowing Liquefied Petroleum Gas (also known as LPG), for cooking food. Do you know it is also used as a automotive fuel in many parts of the world. As like any other fuel it also has some advantages and limitations. Here, in this article we will try… Read More »
Alcohol as Fuel Have seen movies in which crazy scientist uses alcohol as a fuel to his car. That is not merely a science fiction. Anybody can use alcohol as a fuel. Alcohols which are most promising as a fuel are Methanol and Ethanol. But here are some advantages and disadvantages associated with this fuel.… Read More »
What is carburetor? A Carburetor is a Mechanical device used to make an appropriate mixture of air and fuel for burning or combustion. We will explain it in detail but only after when we learn the mechanism of combustion in Petrol (or gasoline) engine and diesel engine. lets start. Difference in Combustion mechanism of Petrol… Read More »
Fueling petrol in diesel engines is a common mistake, which generally occurs at fueling stations. It is a topic of special interest in technical community that what happens in such a situation. Will the engine start, what will be the damages, how to know that there is wrong fuel in our car. Signs that there… Read More »
