Important questions 

share it a link alone

Don't share as screenshot kind request
Unit-1
1.Type of automobile vehicle
2.vehicle aerodynamic system (most important)
3.VVT (definitely ask 2mark question if your luck will be ask 13 marks)
Unit-2
1.SI engine
2.Type of injunction system
3.WGT and VGT
share it a link alone
Unit-3
1.Type of gear box and explain it
2.Differential and rear axle
Unit-4
1.pneumatic and Hydraulic breaking
2.ABS ( expect also part C)
3.Steering geometry and explain gear box working principle
Unit-5
1.Type of alternative fuel and explain it
2.Characteristics of SI and CI engine
3.Hybrid vehicle (expect also part C)
Important note: kindly prepare and draw diagram for all 13 marks question 
PART-C

1.Compulsory Questions {a case study where the student will have to read and analyse the subject }
a situation given and you have to answer on your own

don't waste my hardwork and valuable time

As Engineer i think you know how to respect another
Share it as link alone . don't share it as screenshot or any text material if u found this anywhere kindly report me . #Admin   WhatsApp

Contact uS *These questions are expected for the exams This may or may not be asked for exams
    All the best.... from admin Santhosh

          Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements 
If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates                                                      ~$tuff$£ctor

UNIT I VEHICLE STRUCTURE AND ENGINES 
Types of automobiles vehicle construction and different layouts, chassis, frame and body, 
Vehicle aerodynamics (various resistances and moments involved), IC engines –components-
functions and materials, variable valve timing (VVT).
UNIT II ENGINE AUXILIARY SYSTEMS 
Electronically controlled gasoline injection system for SI engines, Electronically controlled 
diesel injection system (Unit injector system, Rotary distributor type and common rail direct 
injection system), Electronic ignition system (Transistorized coil ignition system, capacitive 
discharge ignition system), Turbo chargers (WGT, VGT), Engine emission control by three 
way catalytic converter system, Emission norms (Euro and BS).
UNIT III TRANSMISSION SYSTEMS 
Clutch-types and construction, gear boxes- manual and automatic, gear shift mechanisms,
over drive, transfer box, fluid flywheel, torque converter, propeller shaft, slip joints, universal 
joints, Differential and rear axle, Hotchkiss Drive and Torque Tube Drive.
UNIT IV STEERING, BRAKES AND SUSPENSION SYSTEMS 
Steering geometry and types of steering gear box-Power Steering, Types of Front Axle, Types 
of Suspension Systems, Pneumatic and Hydraulic Braking Systems, Antilock Braking System 
(ABS), electronic brake force distribution (EBD) and Traction Control.
UNIT V ALTERNATIVE ENERGY SOURCES 
Use of Natural Gas, Liquefied Petroleum Gas, Bio-diesel, Bio-ethanol, Gasohol and Hydrogen 
in Automobiles- Engine modifications required –Performance, Combustion and Emission 
Characteristics of SI and CI engines with these alternate fuels - Electric and Hybrid Vehicles, 
Fuel Cell Note: Practical Training in dismantling and assembling of Engine parts and 
Transmission Systems should be given to the students.
