Supercharger | Definition, Types, Supercharging of engine
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. It lets the engine burn more fuel and do more work, thus increasing power. So if more air is forced & compressed into the cylinder, there will be an increase in the mean pressure & hence will produce more power. The power to the supercharger is provided mechanically by the means of belt(usually), gear, shaft or chain connected to the engine’s crankshaft. Supercharging is a type of forced induction as it is an external application which forces or helps engine…

Automatic Transmission or Automatic Gearbox: Basics, Types, Advantages and Disadvantages
Automatic transmission Basics : An automatic transmission or automatic gearbox is a type of motor vehicle transmission which automatically changes gear ratios while the vehicle is moving thus reducing the driver’s effort to shift gears manually. Like other transmission systems seen on other vehicles automatic transmission allows IC Engine to run at relatively high speed to provide a range of speed and torque outputs necessary for the travel of vehicle. The number of forward gear ratios is often expressed for MT as well.(for eg: 5 speed manual if 5 forward gears, 6 speed manual if 6 forward gears). We take a two similar models of car one with manual and…

Disc Brake: Basics, Main Parts, Advantages, Disadvantages and Preference
Fig: Disc Brake of Bike Basics of Disc Brake: A disc brake is a type of braking system in automobiles that uses calipers to squeeze pairs of brake pads against the rotor/disc to create friction and reduce the motion of vehicle or to completely stop it. When braking action occurs the kinetic energy is directly converted into heat energy and heat is directly dissipated to the atmosphere. The disc braking system works on the principle of pascal law according to which “ the confined liquid transmits pressure without loss equally in all directions.” In disc brake system energy is transfer from pedal to the brakes. It is also a type…

Fuel injectors | Basics, Use, Construction, Working, Advantages and Disadvantages
Fuel Injection or FI is the introduction of fuel in an Internal Combustion Engine by the means of an injector known as fuel injector. Fuel injectors are electronically controlled mechanical devices that are responsible for spraying (injecting) the right amount of fuel into the engine, so that a suitable air/fuel mixture is created for optimal combustion. Why Fuel Injection? Fuel Injection is used instead of carburetor because it offers: More power output. Better fuel efficiency. Reliability. Problem free cold starts. Better drive-ability and smooth engine operation. More benefits includes smoother and crisper throttle response ( during quick throttle transitions), more accurate adjustment to account for extremes of ambient temperatures and changes…

Carburetor | Basics, Construction, Working, Advantages and disadvantages
Basics of Carburetor: A carburetor is a device which mixes air and fuel in a proper ratio(as per requirement) for combustion process in Internal Combustion engine. It works on the principle of pressure difference.( Bernoulli’s principle). It is an essential part of the engine and sometimes it is also refereed as heart of a engine( like heart pumps blood to our body). The carburetion or to carburate is the process to mix the air and fuel and then feed it to the Internal combustion Engine. The carburetor controls the required quantity of fuel and breaks it up into minute globules. This afterward being mixed with the correct quantity of air.…

Two Stroke Petrol and Diesel Engine | Working , Applications
Two-stroke (or two-cycle) engine is a type of internal combustion engine which completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution. As the name suggests two stroke it has only two cycles.This is in contrast to a “four-stroke engine“, which requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. In a two stroke engine power is produced in one revolution of the…

Turbocharger | Basics, Working, Parts and Turbocharging of Engine
In this informative article on Turbochargers we will discuss about the function, working, parts, advantages, disadvantages and finally the applications of a turbocharger. Starting with- Function of a Turbocharger A turbocharger (commonly known as turbo) is a device used in vehicles to force air into an internal combustion engine to improve the power output with same fuel. In other words, Turbocharger is a turbine driven forced induction which increases Internal Combustion engine’s efficiency and power output by forcing extra compressed air into the combustion chamber. It is a form of a supercharger except it doesn’t draw power from engine crankshaft. A turbocharger is basically a combination of a compressor and a…
