Automotive Fuels As we all know that the major fuels that are used in the Automobiles are Petrol in SI engines and Diesel in CI engines, apart from these there is CNG (compressed natural gas) that is also used as a fuel and the Electric Vehicles, but here we will discuss only about the Petrol/gasoline and the Diesel fuel. The Automotive fuel which is used for the purpose of the combustion inside the engine have ratings  or we can say the quality standards on the basis of which we can easily identify the quality of fuel which will be discussed below in details: Rating of Engine Fuel:     In case of S.I (spark ignition) or petrol/gasoline engines, the quality or rating of fuel i.e petrol is  based on the Octane Number, whereas in case of CI (Compressed Ignition) or Diesel engines the quality of fuel (diesel) is determined by the Cetane number. What is Octane Number? It is an expression which indicates the ability of the fuel to resist detonation in SI...

Hey guys in this post we will talk about the fuel behaviour and the combustion process in the IC (internal combustion) engines and we will also look at the various important terms that each and every automotive enthusiast should know about the combustion process i n IC engines. What is Combustion? It is the rapid and high temperature oxidation of fuel with liberation of fuel energy. The requirements for initiating the combustion process are: ·        Combustible air-fuel mixture ·        Means for starting the combustion and formation, stabilisation and propagation of flame inside the combustion chamber of the engine. Some of the very important terms: Ignition Lag or Delay period - It is the first time interval between the instant of spark and the instant when there is noticeable rise in the pressure due to combustion.  Self-ignition temperature - The temperature at which fuel will ig...

In the previous post we told you about the Forced Induction Devices and later We talk about Turbochargers and Superchargers. Now what we see is that sometimes you would find yourself unable to decide about which is better:                 1. Turbocharging the engine?                                      or              2. Supercharging the engine?        Turbocharging will be more efficient but not as fun as the Supercharger.                                   Therefore :           SUPERCHARGER+TURBOCHARGER = TWINCHARGER                                           Twinchar...

Introduction We are all aware of the naturally aspirated engines that we have been seeing since the starting of automotive industry but in the later times came the forced induction systems which brought a completely new power and changed the scenario, as forced induction system increased the performance as well as the efficiency of the internal combustion engines. The Turbocharger and supercharger both are different type of forced induction systems and also both are the best examples of forced induction system. The mechanism of the Turbocharger and Supercharger is quite different but they both use process of compression of air into the engine. The use of Turbocharger and Supercharger is nothing but to increase the performance and efficiency (in case of the turbocharger). What is a Turbocharger? It is a turbine driven Forced Induction device. Turbocharger is being used in about 95% of the diesel vehicles today and is the most popular Forced Induction system. Pop...
