    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…

    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…

    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…

    Combustion Engine | Definition and Types of engine

    A combustion engine is a mechanical device or motor which is designed to convert heat energy into the form of mechanical energy. However, engines are of different types. It has various different applications but most widely used in automobiles. The basic engine types is generally classified with respect to their combustion: 1) External combustion Engine: Fig: External combustion Engine or EC Engine This is an engine in which the combustion or burning of fuel takes place outside of the cylinder. That’s why it is known as EC Engine. However, In this engine heat is obtained by burning of fuel, then it is used to convert the water or other low boiling temperature…
