    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…

    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…

    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…

    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.…

    Electric Vehicle | Basics, Construction, Working, Advantages and disadvantages

    Basics of electric vehicle: An electric vehicle or EV is a type of vehicle which uses one or more electric motors for propulsion. It may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with battery or an electric generator to convert fuel to electricity. An electric car is powered by an electric motor instead of a Internal combustion engine. The electric motor gets energy from a controller, which regulates the amount of power based on the driver’s use of an accelerator pedal. The electric car uses energy stored in its rechargeable batteries, which are recharged by common electricity. Unlike a hybrid car which…
