FORMULA STUDENT (FSAE)

Design and Analysis of Intake Manifold

Aims

• To improve engine performance through comprehensive dynamometer testing and on-track testing. To achieve aminimum of 75 bhp.

• To make a reliable and efficient engine system that is aesthetically appealing.

• To reduce overall weight of the different components in the engine subsystem and to make compact system withbetter packaging.

• To make a light weight system that delivers adequate performance.

• To achieve choked flow in restrictor so maximum air is delivered to the engine and ensure minimum turbulence.

• To ensure that each component can be easily manufactured and ensure easy replacement of the given component in case of failure and indigenize parts to lower cost.

• To conduct data acquisition for future use.

Design and Analysis of Intake Manifold (Restrictor)

DESIGN DECISION REASON

Material : Utem, Durfaform

• Easy availability, cheap and good machinability

Basic shape

• Convergent-Divergent type nozzle• Inlet diameter:35mm• Throat Diameter:20mm• Outlet Diameter:56mm• Convergent length:55mm• Divergent Length:175mm

Analysis techniques:• Analysis was conducted in fluent with a

target to achieve maximum static pressure and reduce turbulence.

Manufacturing • Fused Deposition Modeling, 3D Printing

Design and Analysis of Intake Manifold

Upper & Lower Plenum

DESIGN DECISION REASON

Material : Utem, Duraform • The material is selected as it can be readily used for rapid prototyping.

Basic shape

• Log type plenum with tangential entry to conserve momentum.• Plenum Volume of 2.8L increased from 2.4L to reduce starvation.• Flush type bell mouths to reduce formation of vacuum pockets and increase

air flow to engine cylinders.

Analysis techniques• Based on throttle response. In the initial design a throttle change of 10% led to

starvation, so volume was changed so as to avoid starvation and maintain throttle response.

Manufacturing • It will be manufactured by Fused Deposition Modeling.

Runners and Fuel SystemDESIGN DECISION REASON

Material : Utem, Duraform• The material is selected as

it can be readily used for rapid prototyping

Basic shape

• The intake runners were curved to create a more compact system and to clear the rules for the new chassis.

• The injector housing was integrated into the runners for further space optimization.

Manufacturing• Fused Deposition

MANUFACTURING OF COMPOSITES

Aims

• To Lay carbon-epoxy prepregs on top of the surface of abowl which serves as a mold. The layup is then cured usingan autoclave.

• Modelling of the mold on CATIA & Fiber Simulation onFibersim.

• Manufacturing of Bowl by cutting Prepregs and Hand Lay-Up on mold.

• Curing of Bowl using Autoclave and Vacuum Bagging

• Inspection and Quality check using Macroscopic Analysis and Microstructure Analysis of Results
