Cars, trucks, motorcycles, and other vehicles with internal combustion engines all have in common one dirty little secret. After the engine is started, and until the catalytic converter is up to operating temperature, the engine's exhaust gases are emitting pollutants as if the vehicle did not have a catalytic converter installed. The reason for the delay before the catalytic converter starts doing its job is that it takes time for the engine's hot exhaust gases to raise the catalytic converter from ambient temperature to over a 1000 DEG F. In cold climates, this situation is even more exacerbated.
The featured design is a new engine kinematics. The mechanism that transforms the reciprocal movement of the pistons into rotation of the output shaft is a cam one.
The main components of the cam mechanism is a tubular 3D cam with a groove engraved onto interior cylindrical surface of the cam. The cross-section of the cam profile is an ark that reduces contact stresses. The 3D cam consists of two completely identical halves. In the interior of the 3D cam, two piston-follower assemblies are located. They move asynchronously so that the engine is completely balanced. The piston-follower assemblies are ...
A computational analysis is conducted to evaluate the effect of geometric features on crush behaviour. The objective of this project to modify existing frame for sports unity vehicle based on safety aspects. Reducing vehicle weight is critical to improving fuel economy, performance, size, and cost challenges associated based above requirement to full fill new frame design. Different chassis materials to reduce the weight of the vehicle, improving the vehicle power to weight ratio. Material selection also provide advantages by reducing member deflection, increasing chassis strength and determine the amount of reinforcement required. The improved frontal crash worthiness of cars ...

This continuous combustion 6-cycle engine is a modification of an existing 4-cycle air cooled diesel engine. It operates on the Brayton/Joul (turbine) cycle. Air is ingested and compressed by the piston and transferred to an integral but separate insulated combustion chamber where fuel is added and combustion occurs. The expanding gases are delivered back to the piston for 2 separate power and exhaust strokes to achieve double the expansion volume. The 6 cycles are air intake, compression into the combustion chamber, expansion of half the combustion gases in the piston/cylinder assembly, exhaust, expansion of the remaining combustion gases into ...

FTI has developed a Hybrid Regenerative Energy Recovery System (HERS) that allows motor vehicles to perform their every day tasks much more efficiently than any other vehicle without the technology. It is anticipated that substitution of a HERS equipped CVT for the automatic transmission that is normally specified in full sized vehicles in the US will result in a 10% to 15% improvement in fuel efficiency in the urban driving environment. A savings of 35,100 gallons of gasoline per day would result from installing HERS equipped CVTs in the entire NYC taxi fleet with a corresponding reduction in exhaust ...

My idea concentrates of how to take advantage of the front area of the car already exposed to the air resistance to convert from the negative energy into positive energy. This idea can be carried out by using the electrical motor-generator and put it behind the front flab of the vehicle. The fan blades will be installed on the motor-generator axle to rotate it a result of exposure to air resistance. After rotating the axle, we can convert this motion to electrical energy. The air will be directed through duct to maximize the useful from the air ...
We are very happy to present our project named “CONVERTI-GO,” because it comes with a very noble thought and future view for India.
The main objective of this project is providing an easy, compact and affordable flying car especially for citizens of India and the world. This project, along with being less expensive is also advanced in technology.
1. Double Decker concept: The design is provided with two decks, upper deck is for pilot and co-pilot or family members. Lower deck is for other family members which can occupy two adults or three kids at a time.

DASY X-ENGINE - the best engine configuration for 4-stroke diesel.
Double-Acting Scotch Yoke X-Engine (“DASY X-Engine”) - a new engine configuration for practical applications including stationary power, marine, locomotives, aircraft (planes and helicopters) and automotive (sports cars, luxury cars, trucks). The DASY X-Engine is superior to the V-engine and in-line engine configurations for fuel economy, performance, NVH, package size, weight, durability, reliability and cost while offering an engine OEM the capability to span a 4:1 ratio for displacements using a single bore/stroke for X-8, X-12, X-16, X-20, X-24 and X-32 engines. Currently 3 US patents, one UK patent.

In this railway system we will have a magnetic track which consists of NdFeB block magnets. They are permanent magnets and will create a magnetic field in a direction perpendicular to the track and NdFeB magnets have a property to exhibit the unidirectional magnetic field. This was about the tracks, next comes the train. The whole train will be fixed on a plate, which will be made up of YBa2Cu3O7 (Yttrium-Barium-Copper-Oxide).This material has been chosen because of it's highest critical temperature(93k).This plate needs to be supercooled, this super-cooling is done using the flow of liquid nitrogen on the plate.Liquid ...
To fabricate a four wheel vehicle having steering system with four modes being operated mechanically. The four modes facilitate the following capabilities: 1) To ensure tight turns in heavy traffic and tight spaces.2) To let the vehicle to turn around its central axis which will help in turning at tight spaces.3)To make use of mechanical approach for these different modes. In this process the vehicle has been designed and fabricated in such a way that driver is able to steer the wheels for attaining different modes easily. These four modes uses a screw & nut mechanism and split axle ...
