Automobile Engineering
5 self-contained study topics — notes, diagrams, formulas, and worked examples for exams and GATE.
Topics
- Vehicle Layout and ComponentsVehicle layout (FF, FR, RR, 4WD) fixes engine and drive-axle positions, affecting weight distribution and traction. Rear-drive traction is limited by F_t = μ·W_rear, per automobile-engineering texts (Kirpal Singh).
- Engine PerformanceEngine performance is characterised by brake power BP = 2πNT/60, torque, specific fuel consumption, and efficiency curves. Peak torque and peak power occur at different speeds, per automobile-engineering texts.
- Transmission and DifferentialThe transmission provides gear ratios GR = N_input/N_output to match engine torque to load; the differential splits drive torque between wheels while allowing different speeds in a turn, per automobile-engineering texts.
- Suspension and SteeringSuspension isolates the body from road inputs via springs (rate k = F/δ) and dampers; steering geometry (Ackermann, camber, caster) governs directional control, per automobile-engineering texts.
- Braking SystemsBraking force per wheel is F_b = μ·N_wheel; total deceleration a = μg on a level road at the friction limit. Weight transfer loads the front, so front brakes do more work, per automobile-engineering texts.
