Emerging electric vehicles require high starting torque smooth running high power tracking motors. Developing such motors is a technological challenge.
Currently, hybrid and electric vehicle use motors with rare-earth permanent magnets in the rotor. This eliminates providing current to the rotor which eliminates power loss, and decreases maintenance. Stator fields are switched by power semiconductors driven by processor controllers. This permits performance to be tailored by sophisticated algorithms. Rare-earth magnets such as neodymium-ferrite-boron are used since they can produce fields of about 1.5 Tessa’s matching that of electromagnets. The problem with rare-earth magnets is that they cause the nascent electric car industry to strain world resources.
Switched variable reluctance motors (SVRMs) also operate without electrical connection to the rotor ...
I propose a new approach to implementing vehicular Tire Pressure Monitoring Systems (TPMS) which is more economical and ecological than existing systems mass-deployed in the market to date, with significant advantages, the foremost being the passive non-electronic sending unit (inside the tire) thereby eliminating RF electronics, thermal compensation issues, raising of the RF noise-floor and wasteful consumption of limited Lithium resources for batteries. This is patented, proven field tested technology.
The ATPS TPMS is comprised of two fundamental components per wheel/tire assembly: an in-tire transducer and an external statically mounted chassis sensing component. Signal processing is performed by direct 2 or 3-wire sensor interfaces.
ATPS Pressure Transducer (Sending Unit)
The ATPS pressure transducer directly converts air pressure to a ...
In the process of internal combustion locomotion for most of the energy of the fuel is dissipated into heat energy.
The idea is to provide a radiator effect seebek that recovers part of the thermal energy dispersed into electrical energy to be conveyed, for example in hybrid vehicles, locomotion.
The performance of these cars could easily reach 6-7% more energy savings with an interesting and contribute to lower emissions of greenhouse gases.
The device can be installed simply and easily achieved by redesigning the radiator and engine cooling water to fulfill this ...
The main idea is to create some waiting file at low speed for cars when it is anticipated that they will have to stop in front of a red light.
There is a green wave where cars drive at high speed (within speed limit) where it is anticipated that the green wave will go through the green light.
There is a red wave, where cars are stored at low speed, in order to wait to be caught by the green wave, where then the speed can be higher.
The amount of fuel saved can be calculated by the sum of kinetics energy saved since the car doesn't have to stop and restart. We take the fuel efficiency of the ...
Electric car efficiency can be improved. Current designs use transmissions and differentials. Improved motor design with lower loss allows direct drive without transmissions and differentials. Cost and complexity are reduced and performance is increased. Commercially available lithium-air batteries is a major obstacle to the feasibility of electric vehicles but new discoveries promise to correct this in the near future. Integrate circuit controllers have reduced the cost of electronics making electric cars practical. The benefit of electric cars displacing petroleum-fueled cars could be a paper in itself. The Volt and all hybrids carry the cost burden of a fuel engine. The Leaf does not but is greatly limited by size and battery storage.
The new design motors are ceramic magnets ...
I propose the use of automobile tire grindings as an economical and eco-friendly additive to hybrid rocket motors. To bind the granules, I also propose the use of a low-viscosity, low melting point thermoplastic substance which will not only bond the tire particles but also provide a matrix which will regress at a sufficiently high rate to allow a simple fuel core geometry in a large motor.
The concept chosen is for a model booster of one million pounds force thrust for a 3 minute burn.
The booster would be of the hybrid propulsion genre using an inert rubber fuel grain which would be burned with liquid oxygen as the oxidizer at an oxidizer to fuel ratio ...
The monopoly of using all known internal combustion engines (ICE) has only reciprocators on the ground and gas-turbines (GTE) in the air.
Reciprocator’s drawback is high demand on properties and quality of fuel.
Drawback of low power GTE is huge fuel consumption vs. reciprocators.
INNOVATION: "Rotary-Hybrid Engine - RHE" (see Fig.1,2,3) combines high peak pressure in working chamber and small fuel consumption with advantages of rotary kinematics - high power and low weight.
New quality of RHE is consumption of any fuel. It is provided by permanent fuel burning in always hot combustion chambers.
New quality of RHE is environmental safety. It is provided by flame's effective ignition from small combustion chambers even lean air-fuel ...
Imagine for a moment, a reasonably priced automobile with 5 or even 11 different sized engines in it, one for every driving situation from creeping along in traffic to safely towing a large boat or travel trailer up a mountain.
A powerful computer system controls which engine to use in every situation and thus gives the best possible fuel economy and concomitant lower emissions no matter what the driving conditions are at the moment. You have a durable green economy car and a muscle car in the same vehicle without the need to give up comfort, space and safety. This is an unprecedented capability not currently available anywhere in the world marketplaces at any price.
US Patent #7,779,627 is ...
The future of air transportation is all about protecting the environment and responding to increasing energy costs in a balanced way. In the future, we will need airplanes that are quieter and more fuel efficient and we need to introduce these new technologies without impairing the convenience, safety and security of commercial air transportation.
The response to that is simple: FUEL REDUCTION. This is not an easy goal, There are commonly-considered concepts such as Canard, Forward Swept Wing, Blended Wing Body, and Joined Wing but they do not seem to offer a substantial net benefit when the problems of excess wetted area are included in the assessment.
So the design idea is: How to reduce the fuel consumption of ...
Walking Mechanical Mule
The Walking Mechanical Mule is a very simple, purely mechanical walking platform. It is based on a special form of unique "7 link mechanism." It is actuated by a simple rotating crank and it has NO additional controls!
The Walking Mechanical Mule presented here was built as a "Proof of Principle" prototype and extensively tested. The Walking Mechanical Mule is able to match most of the excellent "Big Dog" performance – except for jumps.
The technical characteristics of the Walking Mechanical Mule are as follows:
Length 1680 mm
Width* 680 mm
Height 525 mm
Weight 80 kg
Payload 100 kg
Operating speed 6 km/h
Operating range** 10 km
* The width was chosen to enable ...
