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…

Drum Brakes : Basics, Working, Advantages and Disadvantages
Fig: Drum Brakes Basics of Drum Brakes: Drum brakes is a type of mechanical braking system that uses friction caused by a set of shoes( a.k.a brake shoe) that presses outwards against a rotating brake drum. The braking action is caused inside of a brake drum thus, giving it a name ‘Drum Brake’. They need regular adjustment of brake wire, brake lever adjustment and requires frequent changing of shoes at a particular period of time after usage. However, these brakes are generally operated with mechanical force by brake pedals but in some other applications they were also operated by hydraulic force mechanism. However, Drum Brakes are only used in low…

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…

Four Stroke engine | Working, Application, Advantages and Disadvantages
Fig: Four stroke diesel engine A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft, unkine two stroke engine which works on two cycle. A stroke refers to the full travel of the piston along the cylinder, in either direction. This type of engine works on otto cycle. Nikolaus Otto was the first person who demonstrated the four stroke engine in 1876. Working: The four stroke engine has four separate strokes. Each stroke has following meaning: Fig: Working of a four stroke engine Intake: This stroke is also known as induction or suction. This stroke of the piston…

Hybrid Vehicles | Basics, Types, Advantages and Disadvantages
What are Hybrid Vehicles? Hybrid Vehicle is a vehicle that utilizes more than one fuel sources or two or more different fuel sources to operate and to move the vehicle or a hybrid vehicle is a vehicle wherein the means of propulsion is by engine which is a combination of IC( internal combustion engine petrol/diesel) engine and an electric motor.The term hybrid vehicle is often referred to the electric hybrid vehicles, which merge one or more electric motors to an internal combustion engine. Hybrid vehicles are often powered by a number of sources such as solid combustibles, human powered, CNG, LNG, hydrogen, electricity, electromagnetic fields, petrol, diesel wind and solar…

Increase Fuel Efficiency of Bike with these tricks
In today’s time, the technology has become advance. It is offering us the right performance which was not available at earlier time. Bikes of today’s time gives us the raw power, right amount of torque, and the pleasure to ride the bike. But how to increase fuel efficiency. Mileage is a strong decision maker when it comes to a bike/scooter, especially in India. Many bike owners are left with no value, although they own a great product with upright performance , just because of the low mileage figure of their bike. But do you know this all comes at the cost of one thing. The fuel efficiency/Mileage. Earlier back in…

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…

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…
