“The Jackknife” – A Center of Gravity (CG) Steering and Leaning Vehicle with Automatic Upright and Directional Stability Control…
For decades, budget conscious police departments have depended on the police motorcycle as effective motorized transport at low cost. However, while more economical, the police motorcycle is exposed to the weather, offers no crash protection and with only 2-wheels - is inherently unstable.
Simply enclosing a motorcycle would seem to be the obvious solutions. However, so far for technical and cost reasons, a police “cabin” (enclosed motorcycle) has defied a practical solution. The proposed “Jackknife” vehicle with the novel “Center of Gravity” Steering System (CGSS) seeks to be that practical solution.
At first sight, the Jackknife is a typical “tadpole” style 3-wheel vehicle with 2 wheels forward and a drive wheel at the rear in an enclosed ...
To give one hundred percent free energy means it's worth everything. As today we are faced with Climate & Environment problems plus with that we are also facing Energy problems as today we have lots of new inventions in energy but still we lack to give 100% pure energy.
The energy today what we have is wind mill, fuel, thermal, solar etc but all of these have drawbacks meaning it’s not safe 100%
My invention 100% Free Energy can be used for automotive engine and creating electricity.

Objective is to improve burning, reduce pollution and extract more power from 4 stroke IC engine which follows Carnot cycle. Following suggestions have been made.
• Currently entire Carnot cycle consisting of 4 strokes is executed in a single cylinder- may be the automobiles may have many such cylinders. But in the proposed modification currently used one cylinder is split into two.
• Suction, compression will be in one cylinder which is at normal room temperature and hence fuel-air mixture ratio is unaffected by hot gases. In-coming fuel-air mixture and out going polluted gases do not mix at all..
• Carnot cycle is now drawn in 3 dimensional axes P, V and T.
• Currently as the piston moves ...
There is a growing scientific consensus that the point of ‘peak oil’ passed around 2011 and that viable global oil reserves will be severely depleted from 2030. The long term future of terrestrial surface transport is electrification but the foreseeable future must involve a cost-effective compromise, using an EV system for ‘town’ driving and an internal combustion engine for ‘country’ driving. The 48V Town & Country Hybrid Powertrain (TC48) is game-changing because it shows how to deliver CO2 and pollution free urban traffic by 2030 - in a way that the average customer can afford without government subsidy.
Say ‘hello’ to EV driving in towns & cities; say ‘goodbye’ to high fuel costs!

A new class of heavily cold rolled and thermally processed (HCR-TP) sheet metals is proposed as a viable low cost alternative to producing light weight vehicles for the transportation industry. Presently, automobile and light truck manufacturers are adapting to rising fuel costs by lightweighting vehicles and making revolutionary changes to powertrains. This new class of materials is based on ferrous and nonferrous sheet metals and alloys that can provide the industry with a highly sought combination of features and properties – light weight, high strength, good formability, and low cost. The new class of HCR-TP materials of choice includes low carbon and low alloy steels that are heavily cold rolled to achieve high strength, and the nonferrous materials of ...
Well-known are Atkinson and Miller cycles. These are cycles with varying compression and expansion ratios. Application of these cycles makes it possible to use working gas energy to a fuller extent.
Suggested herein is a different operation mode of a Diesel engine with varying compression and expansion ratios, when the exhaust valve briefly opens and then closes during the compression stroke. The operation is explained in the following drawings:
Fig.1 – the intake stroke;
then the compression stroke starts (Fig.1b);
further on, the exhaust valve is partly opened with air bleeding from the cylinder into the exhaust path (Fig.1c);
then the exhaust valve closes and the second compression phase starts: fuel is injected into the head-end volume ...
The baby-car, which based on an obstacle crossing chassis, is designed for babies and their parents.
It can be easily and smoothly pushed cross the curb onto pavement from asphalt and vice versa.
In the whole process, the baby can be made sure free of any ...
Imagine this. Next time you buy a car, you don’t have to settle for what’s on a dealer’s lot.
Instead, you design your own car. You buy a Ford body, GM chassis, Intel motor controllers, Toyota wheel/motors, Honda electric power unit, IBM car operating system, and Nintendo driver control unit.
You mix and match modules to fit your needs. Then you can upgrade as technology improves.
We have invented that kind of car. With seven “black box” modules, our new modular design marks the first big change in car architecture since Henry Ford’s Model T in 1908.
Why change car architecture? To solve two problems.
First, car technology evolves slowly. Cars are safer, more reliable, and more efficient than ...
One of the main reserves of improvement in fuel efficiency of ground vehicles is reduction of aerodynamic drag constituting (side by side with the resistance of rolling) the principal component consuming normally a bulk of vehicle’s power to overcome it.
Conventional ground vehicles (including cars, SUVs, trucks, etc.) aerodynamically speaking represent bluff bodies: i.e., bodies characterized by separation of flow and high aerodynamic drag, while providing vehicles with low-drag streamlined bodies preventing separation of flow results as a rule in some unpractical shapes with excessive longitudinal dimensions (caused, e.g. by long smoothly tapering tails) that makes this way doubtful under regular traffic conditions.
The alternative solution of this problem is an Active Aerodynamic System that could form any required ...
The challenge to design the rear suspension of a rear wheel drive sports car has always been one of optimizing the position of both wheels and therefore the contact patch of the tires in order to obtain the maximum possible limit acceleration.
This project takes the active kinematics idea a step further, and for the first time, we present an active system which allows complete control of the wheel by controlling the toe and camber angles on the fly. This allows a more complete control of the contact patch condition which can then further optimize the overall dynamics of the vehicle.
This system, called Active Kinematics Suspension (AKS), is realized by four electromechanical actuators (two per side) ...
