A great intake manifold design can provide substantial performance advantages than a less optimal one. To achieve stagnation of air, plenum is used.
Electric impulse charging is accomplished by installing an electromagnetically-controlled valve in the intake manifold ahead of each cylinder. As the piston travels downward during the intake stroke of the combustion process, the valve is closed, creating a vacuum by sealing the cylinder.
Just before the piston reverses direction to begin the compression stroke, the valve opens and the pressure drop that has been created draws air in at the speed of sound.
The sharp intake of air bounces Air intake manifold formula student the piston crown creating a counter-wave flowing back toward the top of the cylinder.
The valve seals again before the high-pressure wave can escape, resulting in an increased volume of air in the cylinder. As the valve switches from open to closed in a few milliseconds, this charging effect becomes immediately available within one power stroke.
With the electric impulse charger up to 30 percent increase of torque is possible at low rpm. An additional benefit of employing electric impulse charging solution is the increased air pressure in the cylinder at the end of the combustion process improves the purging of exhaust gases.
Far less residual gas is carried over into the intake and compression strokes of the next working cycle, which reduces the combustion chamber temperature and the tendency of the engine to knock. Delphi Active Front Steer Delphi Active Front Steer helps provides drivers with simplified city driving and parking by reducing the turning required at low speeds so that a hand-over-hand parking manoeuvres can be accomplished in as little as two thirds of a turn of the steering wheel.
Delphi AFS smoothly transitions from a low-speed steering ratio to a high-speed steering ratio, providing a tighter, sportier feel for driving enjoyment and better control on the highway. AFS accomplishes this by modifying the steering kinematics, or motion, of the vehicle in a manner similar to steer-by-wire.
Turning into a parking spot or even manoeuvring a hairpin turn at moderate speeds can be accomplished with significantly fewer turns of the steering wheel.
In essence, the system electronically turns the road wheels at a rate different than the rate the driver turns the steering wheel. Although some may think this could be intrusive or controlling, those that have experienced Delphi AFS suggest it helps make driving very easy and enjoyable with a very natural, transparent feel.
Unlike steer-by-wire, AFS maintains the mechanical link and uses the existing electrical architecture. This mechanical link helps ensure system safety.
If the system is switched off or inadvertently loses power, Delphi AFS engineers incorporated a smooth default to the base steering ratio, apparently without disturbing or alarming the driver.
Delphi Active Front Steering can be integrated with controlled braking to provide a more effective vehicle system solution to stability control than brakes alone. AFS instantaneously delivers steering control; counter steering ie opposite lock steering the vehicle to bring it back on its intended course and if needed, blending in braking.
In addition, this integration can help minimize vehicle-stopping distances on split and mixed frictional coefficient surfaces while maintaining directional stability. Delphi Active Rear Steer Not content with Active Front Steer, Delphi is also exploring the use of rear-wheel steering, a technology exploited to some degree by the Japanese in the mid-Eighties.
The demo car that the company is using is a Jaguar S-type. The system is a low angle rear wheel steering system, which is specifically designed to offer European vehicle manufacturers an innovative, affordable solution for dynamic handling enhancement and active safety management on passenger vehicles.
For instance, if the desired vehicle character is for a smoother ride via a softer suspension, Active Rear Steering can be used to help regain the desired handling using an algorithm that dynamically adjusts the rear wheel angle according to a vehicle behaviour model.
The result is optimized handling performance and ride comfort. When combined with the latest in advanced algorithms, Active Rear Steering allows our customers to achieve superior handling performance while also increasing dynamic safety through active rear steering. Emergency lane changes, or elk test manoeuvres, become more predictable, more manageable and less stressful when rear steering is added to the equation.
Active Rear Steering can be integrated with controlled braking to provide a more effective vehicle system solution to stability control than brakes alone.
Together these systems help deliver instantaneous rear steering control to bring a vehicle back on its intended course and blended braking as needed.
This approach minimizes any slowing of the vehicle making the correction less intrusive to the driver.the air intake, exhaust system, engine mounting, fuel tank, braking components, and the uprights for the front suspension.

Formula SAE competition. The Formula SAE is a student design competition organized by SAE International (formerly the Stratasys offered the team free fabrication on its Fortus mc machine in order to prototype both the air intake manifold and steering wheel for the car.
“We wanted to demonstrate to the students what AM and FDM were. Formula Student The design is also impacted by 20mm restrictor on the air intake which will also affect the exhaust system. EGR increases intake manifold pressure.
The higher intake manifold pressure leads to a reduction in the charge cycle work and this lowers the fuel consumption.
During EGR the peak combustion temperature is.
