My Proposed Project:
5/8" Drive Hand Ratchet system with a 3 piece 50" long Telescopic Handle with a group of Hand/Impact Sockets.
This system is to allow a mechanic tighten or loosen bolts (or fasteners if no bolts exist) easily. The system will compliment the 1/4" Dr, a 3/8" Dr, a 1/2" Dr and the 3/4" Drive Ratcheting systems.
5/8" drive system will fall between 1/2" & 3/4" drive systems. A 1/2" drive chrome sockets above 3/4" cannot tighten or loosen with the 1/2" drive ratchet system available because the handle length is not long ...

Bicycle is used as mainly short distance carrier. Speed of a cycle generally 15-20 km/h, if we pedal it comfortably. We can get more speed by fitting big-size front chain ring (with increase number of teeth of ring) or increasing rate of rotation. But both are laborious for human. To get high speed without hard labor I have thought of an innovative idea.
In my innovation we can get more than double speed by fitting double size front chain ring, but do not need extra manpower. For it two chain ring to be fitted at the two side ...
Lithos Motors is an automobile startup that focuses on providing innovative, clean energy transportation for urban commuters.
At Lithos Motors, we aim at changing the way India commutes. The world will shift to clean and green transportation solution in coming years, and we aim to act as a catalyst for this journey. Also due to increasing use of public transport, future will be of short distance travelling and we aim to tap it. We have designed and manufactured a compact, foldable, lightweight, ultra-portable, electric ...

Internal combustion engine is the most efficient and economical on-road power machinery and maintains the dominant role on the market. Among them, SI engines occupied a much higher proportion on the light vehicle engine markets than diesel engine. However thermal efficiency of SI engine is not satisfying and ideal, especially at high speed and load operations. Because of exhaust temperature limit, fuel enrichment technology, indicated by air-fuel ratio on figure 1, is required to ensure the proper work of turbine and catalyst, resulting in much fuel lost and emission deterioration shown in figure 2.
Currently, this fuel enrichment ...

The Clarke-Brayton Engine has the potential for 55% brake thermal efficiency compared to 42% for state-of-the-art conventional diesels, is dramatically more compact than conventional engines of the same power, can burn diesel or natural gas as compression-ignition fuels and is less expensive to manufacture. Two prototypes have been manufactured and tested, the latest of which has demonstrated 45% indicated thermal efficiency, including losses for gas mixing and pumping. The test results have shown a clear path to 59% indicated thermal efficiency.
As shown in the submitted video, the engine is composed of modules of three cylinders – an intake ...
Currently ECU is used in cars to increase performance. This MechaSpark ECU is a LOW COST microcontroller based ignition system which increased the power output of engine and REDUCED FUEL consumption. This is can be TUNED to provide various performance modes such as MOUNTAIN-CLIMBING, HEAVY-TRAFFIC, OFF-ROADING, etc. It is much CHEAPER than a conventional ECU and can be incorporated without major modifications in existing bikes. It DOES NOT involve high MANUFACTURING cost. It just needs a hall sensor and timing markings.
It increases PERFORMANCE and reduces FUEL CONSUMPTION there by it is ECO-FRIENDLY. It is fully automated, ROBUST, SAFE, ...
The basic motivation of this innovation is to use hydrogen as the fuel of the engine without using a very expensive and bulky hold-up tank for liquidized hydrogen storage.
A water tank will be used as the origin of the hydrogen. A pair of electrodes will be used inside the tank with more effective area exposing for ionizing the water and generating the oxygen and hydrogen as fast as possible. The mixed gas with oxygen and hydrogen will be directed to the engine with a sealed pipe.
The engine will work analogously to a normal gasoline engine with 4 strokes, ...

One clear and necessary development is the replacement of the millions of friction brakes with kinetic energy storage systems on all sorts of vehicles: refuse trucks, shuttle busses, delivery trucks, and automobiles. Hybrid vehicles dominate in the area of regenerative braking owing to (1) motivation, and (2) easy implementation. Petroleum-based vehicles will continue to be the only solution for many applications.
For braking and acceleration, it is specific power that is the over-riding parameter. This is the rate that energy can be retrieved and stored and the rate at which it can be returned during an acceleration phase. The ...

Many developments of hybrid vehicles aim to reduce power of their electric propulsion chain, obviously for economic reasons, but not only. We can also get a better efficiency by reducing the energy transformations and a better safety by decreasing the electric voltage.
As described in a previous contest session, refer to: http://contest.techbriefs.com/2013/entries/transportation-and-automotive/3519, a series-parallel architecture with a dual train (two planetary gear systems) has this purpose. To illustrate, figure 1 compares the vehicle accelerations with a 10 KW dual electric chain to a vehicle with a 20 KW single electric chain. We almost get the same results.
Hybrid vehicles ...
The cylinder diameter is typically a few times or more of the stroke. When the piston nears the end of the compression stroke, vertical ridges on the piston, in conjunction with almost mating vertical ridges in the cylinder head, effectively partition the combustion chamber into multiple combustion chambers.
Fig. 1 shows four partitions, each with a valve and two spark plugs.
A rotary start stop mechanism is connected to an external flywheel. The flywheel (operating through the rotary start stop mechanism) supplies energy for compression and absorbs energy from combustion. The rotary start stop mechanism always stops at the ...
