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…

Hydraulic brakes: Basics, Principle, Working, Advantages and Disadvantages
The brakes or the system of braking mechanism which are operated and applied by liquid or oil pressure from controlling mechanism to braking mechanism in order to slow down or completely stop the vehicle is known as hydraulic brakes. In simple language, hydraulic brakes are brakes which uses oil pressure for braking action. Main parts of hydraulic brakes: The main parts of hydraulic brakes are: 1) Master cylinder: The master cylinder, also known as the master brake cylinder, converts the pressure on the brake pedal to hydraulic pressure by feeding brake fluid into the brake circuit and controlling this according to the mechanical force. Disc and drum brakes, both uses…

Air brakes: Basics, Components, Working
What are Air Brakes? Air brake system is a type of braking system which uses compressed air to apply the pressure in order to stop the vehicle. Air brakes are also known as pneumatic brakes. The first air brake was invented by George Westinghouse, he introduced this type of brake for the use in trains. Air brakes are widely used in heavy vehicles like trucks and buses because they are heavy in weight and they need more effort on brake pedal to stop them, and for comfortably braking them air brake is good as it has high potential energy and does not requires much effort to push the brake pedal.…

Engine Oil : Its Types, Different Grades and its Properties
Engine oil: Engine oil is a type of lubricant which is used to lubricate the internal components of IC Engine. It is quenched by oil pump to all the internal moving parts of the engine. Engine oil are present in large varieties in the market with specified volume (like 900ml,1 litre, 1.15 litre, etc). Main functions of an engine oil are: To reduce the temperature: As there are number of moving parts in an engine. They relatively move at very high speed depending on engines’s rpm. So they will produce heat in large amount. The engine oil helps in reducing that heat so that moving parts can move at high…

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…
