Self-driving car technology will disrupt the traditional experience of drivers and occupants. Where once the driver, and to some extent fellow riders, were 100% focused on the road and surrounding objects, behest not only by law, but by self-preservation, future unconstrained travel frees the driver and occupants for an improved quality of life. In a mobile computing world, care free, liberated transit opens the door for a mobile phone application to control and monitor the vehicle’s destination, health, security, and operating charges. Having this need fulfilled, yields a software solution that changes the purchasing mindset for both the seller and consumer of goods and services. The value provided to the traveler, in terms of managing the overall vehicle and ...

N2BYK is motivated by the need to find a clean, cheap way for personal transportation, especially with increasing fuel prices (specifically in my home country Egypt which will be the base of manufacturing) and the effect of pollution, global warming, and climate change. There are different prospects for transcending the product to bigger vehicles that would be used for group/public transportation and even land shipments, saving cost and the future.

N2BYK consists of:
1. Mini DC compressor and battery
2. Two separate nitrogen cylinders on both sides
3. Air motor
4. Housing and cover made from ABS
5. The top of the housing acting as a chair
6. Protrusion in the housing for foot resting
7. Handle bar with ...

The present experimental work aims at investigating the effect of zinc oxide and titanium dioxide nanoparticles addition in Calophyllum inophyllum biodiesel in a twin cylinder water cooled direct injection four stroke diesel engine. The nanofluids have been prepared from 50 ppm and 100 ppm concentrations of titanium dioxide and zinc oxide with distilled water through an ultrasonication process. Four different Calophyllum inophyllum nano emulsions have been prepared with the proportions of 93% of Calophyllum inophyllum biodiesel, 5% of nanofluids of zinc oxide and titanium dioxide and 2% of span 80 using mechanical stirrer. The compression ignition engine characteristics were examined with all four Calophyllum inophyllum nano emulsions and the results were compared with conventional diesel and pure Calophyllum inophyllum ...

The crankshaft is a key part moving in the internal combustion engine. It converts the reciprocating piston movement into rotary motion. It is exposed to different forces resulted from the pistons pressures, friction, bending stresses and others. The paper concentrates on protecting the crankshaft journals from the direct impact of the piston pressure and other forces. It presents a familiar new modular product design. From this concept, a work has done with the additional of the so-called 'load bearing' (two halves of a highly finished surfaces sleeve) embedded within the crankshaft journal. The proposed load bearing isolates the crankshaft journal and takes the place in the contact with other rotating components. This is an experimental research because of the ...

Homogeneous charge compression ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. As in other forms of combustion, this exothermic reaction releases energy that can be transformed in an engine into work and heat. HCCI combines characteristics of conventional gasoline engine and diesel engines. Gasoline engines combine homogeneous charge (HC) with spark ignition (SI), abbreviated as HCSI. Diesel engines combine stratified charge (SC) with compression ignition (CI), abbreviated as SCCI.

As in gasoline engines, HCCI injects fuel during the intake stroke. However, rather than using an electric discharge (spark) to ignite a portion of the mixture, HCCI raises density and temperature by compression until the ...

ParallelDrive is a concept of convertible fully electric vehicle which is used as a four wheel car and it can transform into two separate bikes. It consists of two bikes and car cabin. In each bike power train unit, power bank, motor controller etc. While converting these two bikes into a four wheeler, each power train and power bank work as a single unit to drive as a ...

It is a new way of personal transportation which is non-polluting, electric, comfortable and a fun ride. It's quick, sturdy and a life-long machine. It is powered by a heavy duty motor and runs on a set of leak proof batteries. The electric vehicle is also equipped with a differential of 1:10 gear ratio that provides sufficient torque to carry a load of more than 1000 Kg. With its top speed going up to 25 Kmph it is also equipped with powerful drum brakes on both the front tyres. Further, it is easily maneuvrable through its rear wheel steering, that also acts as the third and the final support to the vehicle.

For this I have proposed a tadpole ...

Piston-chain arrangement in IC engine is a method to replace the crank shaft by chain/belt and two connected sprocket/wheels. This method can convert the rotational motion of the crank shaft to a combination of rotational and linear motion. The main advantage of this method is its high efficiency. In the present IC engines, the diameter of crank shaft is equal to the stroke length and the crank angle at the beginning of power stroke will be much less. So, major portion of piston force will be wasted in the crank shaft and a small portion of piston force will be used for rotating flywheel. At 10 degree crank angle, about 88% of power is lost but only 66% of ...

Precious CarGo™ Abandoned Occupant Alert System™
We’ve all seen the horrific headlines: babies, children and pets left alone in hot cars, leading to serious injury and death. The National Safety Council estimates that 38 children die each year abandoned in hot cars, plus countless injuries, and pet casualties, too. So, we designed the Precious CarGo™ Abandoned Occupant Alert System™. It is a portable, self-powered electronic alerting system, similar to a baby-on-board sign, but with intelligence.

Precious CarGo™ simply clips onto the window of any car, van or SUV, so it moves easily with an infant or child booster seat. It has a sign component on the outside of the window, and a sensor component on the inside of ...
