We believe to make cars lighter, the automotive industry needs to replace aluminum with iron.

The conventional wisdom says that is crazy.

Why would you replace a low density material with a higher density material? We just spent years and money converting parts from iron to aluminum. We are still working to do that. Why would you convert steering knuckles or other components back? Are you guys just nuts?

The problem with aluminum is that it is weaker. Therefore even with low density, you need more of it to distribute a load. Compared to iron or steel, you need the aluminum to be about 4 times as thick. It is well established that when taking into consideration both density and material ...

Contemporary gasoline-powered vehicles use On-Board Diagnostics 2 (OBD2) to determine whether a vehicle is within emission standards. This is achieved by monitored certain parameters; e.g., catalytic converter operation, exhaust gas recirculation operation, etc. Rationality testing on sensors is also done; e.g., whether engine coolant temperature readings make sense. OBD2 is incapable of finding certain problems. For example, on a two-bank engine with oxygen sensors on each bank and a defective O ring on an injector OBD2 may not report problems on that bank as long as it can adjust its air/fuel mixture to 14.7/1. The driver may notice a rough engine and abnormal fuel consumption. The problem may be seen by connecting a scan tool to the engine and ...

GDI Magnetic Injector and Fuel Rail Solenoid Tester. The magnetic unit can test GDI injectors and the fuel rail pressure control solenoid, which can sometimes employ 14 to 24 volts and is also PWM controlled. Maximum voltage is at 55 volts variable and uses positive and negative driver ...

Windshield wipers are designed and made to remove rain, snow, ice and debris from a windshield. Most cars have two wipers on the windshield, and they may have one on the rear window and one on each headlight. A wiper generally consists of a metal arm; one end pivots, the other end has a long rubber blade attached to it. Wiper blades should be replaced every six months to a year or as soon as you notice a difference in driving visibility. When wiper blades no longer make proper contact with the windshield surface, they can begin to squeak, chatter, skip, smear or streak reducing driving visibility. So, wipers have big possibilities to be damaged easily on many factors. ...

The reason why we started this project is due to the mindset of the general public, that is changing towards a more responsible way of consuming and living; for the daily commute, we saw that people are slowly but surely preferring personal transportation instead of cars that are meant for multiple passengers and are mostly used by one person. Likewise, consumers have a growing interest in vehicles powered by electricity rather than fossil fuels.

We identified the growing market of electric scooters, that lead us to believe, that there was a great opportunity to grow on this market, not only by creating another scooter but by trying to create something new and innovative; in a market that doesn´t seem to ...

According to AAA’s Foundation for Traffic Safety, poorly secured loads are responsible for more than 25,000 crashes and approximately 90 fatalities in developed countries each year. And on top of that, there are all those nonfatal injuries to drivers behind you and damage to their vehicles. There are many ways to secure loads on pickup but none of them guarantee the safety and this project will guarantee the safety we need while driving loaded pickups.

This invention is a mechanism for pickup trucks to extend their trunk when carrying a long material or material which take higher surface area and carry more load without having the risk of instability in the vehicle under the capacity of the vehicle. This ...

Commuting in megacities is still an unsettled issue and while population increases so does the restrictions and disapproval. For example, in New York City, among other problems “traffic congestion is causing damage to economic health to the tune of $20 billion a year. That $20 billion figure comes from looking at four categories where businesses and residents are forced to spend or lose money – travel time, operating costs, excess fuel and lost revenue” according to a study conducted by HDR for the Partnership for New York City*.

By listening Gen Z talking about the future of urban mobility, all seemed to agree with “a gucci capsule that flies and behaves lit”, the Boomers somehow approved this recalling “The ...

Electric cars are limited as to the distance that they can be driven before complete battery failure; the average range is only about 100 miles. When the battery runs out of power the car is forced to stop and it is very hard to connect to a power supply for charging if the driver is in a remote area. This project is about building a mechanism that can charge an out of power battery electric vehicle while it is moving. This can be done when the electric vehicles run out of battery, the driver calls to the nearest electric car battery supply shops and another car will come to the location of the electric car. The car can be ...

A rotating internal combustion engine using spark or compression ignition manufactured with current metals/machining processes for motorcycles, automobiles, shipping, and aircraft. An attached compressor (twin screw) feeds air injectors, supplying the rotor chambers.

Pyramidal rotor chambers are placed around the rotor circumference allowing multiple firing impulses per revolution, with any design of rotor vanes, chambers, or diameter to maximize output.

One design for a light/medium truck, with an 18” diameter rotor holding (6) rows of (9) chambers, has external dimensions like a Chevy 454. At rest, a number of chambers are positioned to allow for pressurization/fuel/spark allowing instantaneous startup without a starter motor. When starting, any number of chambers can ignite, and immediately other chambers are positioned to ignite.

Autonomous vehicles require multiple optical sensors, such as cameras or LIDAR, in the car’s body on all sides. Today, such sensors are mostly used for parking assistance.

In automated driving, the accurate function of these sensors is required to ensure safe driving. Contaminants such as dirt, dust, organic material and different phases of water (ice, rain, snow, etc.) on the surface of the sensor yield blurry and inaccurate images, thus leading to erratic system performance.

This project is about building a cover mechanism for camera of a car that does not require cleaning and protect the lens of the camera from giving blur vision due to particles like dust, rain, snow and so on. This can be done using ...
