What is supercharger/ how supercharger work/ types of superchargers.

 Supercharger:        A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do work, thus increasing power.         Power for the supercharger can be provided mechanically by means of a belt, gear, shaft, or chain connected...

Types of Carburetors / Constant Choke Carburetor / Constant Vacuum Carburetor / Multiple Venturi Carburetor

 Types of Carburetors:        There are three general types of carburetors depending on the direction of flow of air. The first is the up draught type shown in Fig.1 (a) in which the air enters at the bottom and leaves at the top so that the direction of its flow is upwards. The disadvantage of the up draught carburetor is that it must lift the sprayed fuel droplet by air friction. Hence, it must be designed for relatively...

Fuel Injection system for SI engines /Carburetion /Factors Affecting Carburetion/Definition of Carburetor/Principle of Carburetion

 Fuel Injection system for SI engines:1.1. CarburetionSpark-ignition engines normally use volatile liquid fuels.Preparation of fuel-air mixture is done outside the engine cylinder and formation of a homogeneous mixture is normally not completed in the inlet manifold. Fuel droplets, which remain in suspension, continue to evaporate and mix with air even during suction and compression processes. The process of mixture preparation is extremely...

CRDI - (Common rail fuel injection system) / CRDI Working Principle.

 CRDI - Common rail fuel injection system:         Common rail direct fuel injection is a modern variant of direct fuel injection system for petrol and diesel engines. On diesel engines, it features a high-pressure (over 1,000 baror 100 MPa or 15,000 psi) fuel rail feeding individual solenoid valves, as opposed to low-pressure fuel pump feeding unit injectors (or pump nozzles). Third-generation common...

CYLINDER BLOCKS

  CYLINDER BLOCKS           All the major engine components, are installed on or in the engine block. These components including the cylinder bores, are machined very precisely. They must be thick enough to contain the pressure of the burning fuel mixture. A tight fit must be ensured between the cylinder base and the piston rings to enable the piston rings to seal the combustible gas. If the...

Automatic Transmission / automobile gearbox /Automatic Transmission Modes/ Automatic Transmission Parts

 Automatic Transmission:          An automatic transmission (commonly "AT" or "Auto") is an automobile gearbox that can change gear ratios automatically as the vehicle moves, freeing the driver from having to shift gears manually.  Automatic Transmission Modes:          In order to select the mode, the driver would have to move a gear shift lever located...

What is Differential Unit ? How Differential Unit work.

 Differential Unit:Differentials are a variety of gearbox, almost always used in one of two ways. In one of these, it receives one input and provides two outputs: this is found in every automobile. In automobile and other wheeled vehicles, the differential allows each of the driving wheels to rotate at different speeds, while supplying equal torque to each of them. In the other, less commonly encountered, it combines two inputs to create an...
