Human /Powered Hybridized Vehicles
Bicycles are one of history’s most efficient machines converting up to 95% of rider energy into forward motion. Automobiles don’t come close to the efficiency of bicycles.
Pedalectric Vehicle Features
• Low to zero carbon emissions
• Low cost basic configurations
• Utilizes existing technologies
• Variable configurations
• Open source architecture and power sourcing for rapid evolution
• Sourceable from many facilities
4 Wheels vs 3
Unlike vehicles with similar design goals, the Pedalectric has 4 wheels instead of 3. This makes the Pedalectric easier and safer to operate by being more ...

Today we are familiar with the hybrid concept in four wheelers. It has a advantage of fuel saving, low pollution. But why not in two wheelers? Here it is. The Hybrid Bike. It is combination of regular IC engine powered bike+electric bike. Also the provision to eliminate the external charging is also there. The parts are electric BLDC hub motor, alternator, bevel gear train, Li-Ion battery to store the electrical energy generated through alternator & regular bike.
The alternator is attached to the rear wheel through a bevel gear train, BLDC hub motor is within the rear wheel as ...

The key challenge in designing vehicle suspension springs is primarily to cost-effectively strike a balance between vehicle ride comfort, road holding, and load carrying capacity. A Hybrid micro-composite E-like shaped spring strikes such a balance cost-effectively. Its advantages include
(1) Light weight:
For instance, the E-spring weighs 25% less in comparison with the traditional semi-elliptic multi-leaf spring, which implies fuel consumption economy improvement;
(2) Compact rattle space requirements:
For instance, the E-spring saves almost 75% of the rattle space required by the semi-elliptic multi-leaf springs;
(3) Less costly:
For instance, the E-spring saves almost 25% of the aggregate ...

It is known that usually electric vehicles named trolleybuses can circulate on ways shared by general urban traffic, but that they will have to follow imperatively the trajectory imposed by their source of energy supply, a feeder usually named catenary (dual overhead line) system. This “in motion charging system” limits the vehicle speed at 70 Km/h and consequently the trolleybus cannot be used on highways.
A new solution is proposed by the Hybrid Transport System - HTS , which seems to solve the main problems of trolleybus (see also www.hybrid-engine-hope.com/hybrid_transport_system). A truck (or bus) hybrid powertrain can ...

Planetary gear-sets can be incorporated in the design of an IC engine by replacing the conventional style crankshaft. This concept could be used in IC engines of all sizes, two or four stroke, gas or diesel, the only stipulation being, in its simplest form, the architecture be that of a “boxer” opposed cylinder configuration.
The mechanism's principal benefit is to provide the piston with a connecting rod attachment that eliminates ALL angular thrust between the piston and cylinder wall. Additionally, engine designs would no longer require the fabrication of a forged, cast or billet crankshaft to provide drive to ...

An IEDD or Impact Energy Dissipater Device meant for the prevention of fatal injury from impact related incidents of high-speed vehicles and the like. The IEDD dissipates a very large amount of kinetic energy in an innovative mode whereby the forces generated by the impact are dissipated into manageable form meant for the protection of the most delicate living being in the vehicle and avoid catastrophe failure. Its primary purpose is to prevent fatal ...

The presented idea is a full mechanical, magnetic and electrical design of an in-wheel brushless DC outer rotor (hub) motor. The rim of any wheel would serve as the rotor, after some modifications, for the motor. Varying rims sizes yields varying power throughput. The larger the rim the higher the output power.
A major advantage is that the entire Magneto-Motive Force (MMF) developed is utilized to drive the wheel i.e. higher efficiency overall; this was practically realized by using the rim itself as the rotor. The rim was modified to include magnetic elements and metal inserts to ...

While there have been many technological advancements in vehicle braking systems over the years (4-Wheel Disc, Anti-Lock, Electronic Stability Control, etc.), widespread advancements in friction materials and their manufacturing processes are few. The problematic nature of today’s resin bonded metallic (“RBM”) materials (including environmental, wear and performance issues, as well as declining quality from offshore production), represents a step backward from asbestos-based linings which held ~90% market share until matters around asbestos came into focus in the early 1990s.
Ceramic and carbon friction materials demonstrate some, but not all of the value characteristics of our highly engineered friction composites; ...

It is a known fact that the two basic engine types, internal combustion engine and external combustion engine are individually not very efficient, as neither of them has efficiency greater than 40%. This is because of the fact that when a fossil fuel burns, the energy is released in the form of heat and explosion but none of the above mentioned engines are able to utilize both these forms for producing useful output. Hence if the working of these two engines is integrated then there is a scope of producing an engine that is highly efficient & effective.

I have an idea to make the road safe and road signs interactive, by using a screen in the car with installing receiver device and installing transmitter device into road signs which will transfer the data from the sign to the car's screen to inform the driver by the data in the sign as alarm or even warning. Also, we can include the speed limit when the sign said the speed limit is 100 km/h so the fuel actuater will decrease the amount of fuel then the speed will be reduced to the limited speed as in the sign....
