Working of a Car

When a driver turns a key in the ignition:

●      The car battery powers up sending

●      Power to the starter motor, which

●      Turns the crankshaft, which

●      Gets the pistons moving

●      With the pistons moving the engine fires up and ticks over

●      A fan draws air into the engine via an air filter

●      The air filter removes dirt and grit from the air

●      The cleaned air is drawn into a chamber where fuel (petrol or diesel) is added

●      This fuel-air mix (a vaporized gas) is stored in the chamber

●      The driver presses the accelerator pedal

●      The throttle valve is opened

●      The gas-air mix passes through an intake manifold and is distributed, through intake valves, into the cylinders. The camshaft controls the opening and closing of the valves.

●      The distributor makes the spark plugs spark, which ignites the fuel-air mix. The resulting explosion forces a piston to move down which in turn causes the crankshaft to rotate.

The layout of a Car

        In automotive design, the automobile layout describes where on the vehicle the engine and drive wheels are found. Many different combinations of engine location and driven wheels are found in practice, and the location of each is dependent on the application the vehicle will be used for. Factors influencing the design choice include cost, complexity, reliability, packaging (location and size of the passenger compartment and boot), weight distribution, and the vehicle's intended handling characteristics.

        Layouts can roughly be divided into two categories: front- or rear-wheel drive. Four-wheel-drive vehicles may take on the characteristics of either, depending on how power is distributed to the wheels.

Gear Ratio and Torque Calculation

-

Gear Ratio             The gear ratio of a  gear train  is the ratio of the angular velocity of the input gear to the angular velocity of the output gear, also known as the speed ratio of the gear train. The gear ratio can be computed directly from the numbers of teeth of the various gears that engage to form the gear train.                In simple words, the gear ratio defines the relationship between multiple gears.   Gear Ratio= Output gear # teeth / Input gear # teeth                  For example, if our motor is attached to gear with 60 teeth and this gear is then attached to a gear with 20 teeth that drives a wheel, our gear ratio is 60:20, or more accurately 3:1                If you do not want to count a gear's teeth (or if they do not exist), gear ratios can also be determined by...

Types of Flexible Coupling – Bibby Resilient Couplings

Types of Flexible Coupling – Bibby Resilient Couplings                  Named after its Inventor Dr. James Bibby in 1917, this coupling is still one of the most sought after flexible couplings for heavy shock applications. Let us now look at the constructional features of the coupling. 1.       The Coupling consists of two flanges or hubs specifically mounted on the drive and the driven shafts respectively. These hubs contain axial grooves cut on their circumference. 2.       The two couplings are joined or held together by means of a specially designed grid spring. 3.       The total assembly is enclosed in a casing or shell filled with grease for low-speed applications or, in high-speed applications with high viscosity oil. Now let’s look at the working aspect of the coupling and how it tends to reduce vibration and prevents the build-up of resonance in the syst...

Safety Systems in Vehicles | Seat Belts | Air Bags

Safety Systems in Vehicles | Seat Belts | Air Bags Seat belts                The function of the seat belts is to restrain the occupants of a vehicle in their seats when the vehicle hits an obstacle:                Three-point seat belt: In motoring history, this is the single most significant advance. All credit goes to Volvo’s Nils Bolin for devising it and to Volvo for introducing it in 1959. The three-pointer afforded unrivaled restraint. Its use was a quick, easy one-handed operation. Many improvements have been made to the webbing, mountings, latches, and inertia reels and belts have got smarter in relating to accident severity and occupant weight. In the present day vehicles, seat belts have become mandatory for the driver and front passenger. Some vehicles have seat belts for rear passengers also.                Seat belt pre-tensioner: A spring-...
