Fold Able Electrical Bicycle


Fold-able Electrical Bicycle:-

 This bicycle is designed to generate energy when riding and this energy can be used as currency to pay for your bus rides. The bike electronically folds into the bus seat storage mode for space and weight efficiency and to fit on the bike stand. Bike stands can be found at the bus stops where the bikes will be stored securely in order to collect energy from the sun and wind. Moreover, it contributes energy to the bus system that was generated during riding and stored in inner batteries. Finally, the energy will be accumulated from all the bus stops in one place, which is the Universal Electricity Network of this concept.

EIGHT CYLINDERS IN AN ENGINE


Dynamic Vehicle Control (DVC)

The Dynamic Vehicle Control (DVC) system developed by Brink Dynamics, a division of the Brink Technology Group, overcomes existing technical barriers and can enable manufacturers to produce an innovative class of enclosed narrow vehicles that can satisfy user needs and desires. An ENV can fulfil the market demand for a comfortable and safe single/dual transportation alternative and offers the following advantages: - A unique, sensational driving experience - Drives like a traditional car (no additional driving skills) - Top acceleration, comfort and safety comparable to the ‘middle-class car’ - Greater agility in traffic - Safe and predictable, even under difficult road conditions - Reliable and fail-safe - Mass production costs less than a traditional car - Energy efficient (1:33 ECE mix), lower road taxes - 40% lower emissions (fuel propulsion system). Possible to install all innovative propulsion technologies to combine the advantages of propulsion and form.

Disc brakes


Disc brakes

Disc brakes are an order of magnitude better at stopping vehicles than drum brakes, which is why you'll find disc brakes on the front of almost every car and motorbike built today. Sportier vehicles with higher speeds need better brakes to slow them down, so you'll likely see disc brakes on the rear of those too.
Disc brakes are again a two-part system. Instead of the drum, you have a disc or rotor, and instead of the brake shoes, you now have brake caliper assemblies. The caliper assemblies contain one or more hydraulic pistons which push against the back of the brake pads, clamping them together around the spinning rotor. The harder they clamp together, the more friction is generated, which means more heat, which means more kinetic energy transfer, which slows you down. You get the idea by now.

ACL (Active Cornering Lights)


ACL (Active Cornering Lights):-

 ACL provides support for night driving by additionally illuminating the direction in which the vehicle is moving in accordance with the steering angle. 35W halogen bulbs are used in the cornering lights. The system links with the turn signal light at speeds of 40km/h or less and also links with the angle of the steering wheel to additionally illuminate the direction in which the vehicle is moving. ACL makes driving at dark intersections, curves, etc. safer.

Differential

Working:-

          In an automobile, the power from the propeller shaft is transmitted to the wheel axiles through the differential. while turning a curve, the outer wheel has to move more distance than the inner wheels, also power has to be transmitted to both wheels. this is achieved by differential.

Cylinder Block

Single Cylinder Block:-

V type Cylinder Block:-

Cylinder Block:-
        The cylinder block is one of the major parts of an IC engine. on the top, it is connected to cylinder head and to the sump at the bottom. it houses the cylinder,provision for engine oils, water jackets etc. previously it was made of cast iron. nowadays aluminium alloys containing silicon is used.
    
         A cylinder block is an integrated structure comprising the cylinder(s) of a reciprocating engine and often some or all of their associated surrounding structures (coolant passages, intake and exhaust passages and ports, and crankcase).

CrankShaft

Crank Shaft with Explanation:-

Offset Engine:-

     The crankshaft, sometimes usually abbreviated to crank , is the part of an engine that translates reciprocating linear piston motion into rotation. To convert the reciprocating motion into rotation, the crankshaft has "crank throws" or " crank pins", additional bearing surfaces whose axis is offset from that of the crank, to which the "big ends" of the connecting rods from each cylinder attach.

Connecting rod


Connecting rod:-
     
         In a reciprocating piston engine, the connecting rod or conrod connects the piston to the crank or crankshaft. Together with the crank, theyform a simple mechanism that converts reciprocating motion into rotating motion. Connecting rods may also convert rotating motion into reciprocating motion.
