Question 1191. A traction control system (TCS) in automobiles controls the
  1.    vibrations on the steering wheel
  2.    engine power during acceleration
  3.    torque that is transmitted by the tyres to the road surface
  4.    stopping distance in case of emergency
 Discuss Question
Answer: Option C. -> torque that is transmitted by the tyres to the road surface
Question 1192. The function of anti-lock brake system (ABS) is that is
  1.    Reduces the stopping distance
  2.    Minimizes the brake fade
  3.    Maintains directional control during braking by preventing the wheels from locking
  4.    Prevents nose dives during braking and thereby postpones locking of the wheels
 Discuss Question
Answer: Option C. -> Maintains directional control during braking by preventing the wheels from locking
Question 1193. The drive-shafts are connected to the differential and wheel hubs through universal joints because the universal joints
  1.    Absorb the vibrations transferred from the surface of the road
  2.    Compensate for variations in the relative positions of the differential and the wheels which result from bumpy road surfaces or other similar driving conditions.
  3.    Absorb any difference in speed between the left and right wheels when the vehicle is turning
  4.    None of the above
 Discuss Question
Answer: Option B. -> Compensate for variations in the relative positions of the differential and the wheels which result from bumpy road surfaces or other similar driving conditions.
Question 1194. If the air-fuel mixture in a spark ignition engine is too rich, then air-fuel ratio is about
  1.    17:1
  2.    15:1
  3.    13:1
  4.    10:1
 Discuss Question
Answer: Option D. -> 10:1
Question 1195. The firing order for an in-line four cylinder I
  1.    1-2-3-4
  2.    1-3-4-2
  3.    1-2-4-3
  4.    1-3-2-4
 Discuss Question
Answer: Option B. -> 1-3-4-2
Question 1196. The condition that causes vapour locking in a brake system is
  1.    Overheating of the fluid due to frequent brake application
  2.    Overcooling of the brakes during high speed driving
  3.    Keeping the vehicle without use for an extended period
  4.    An excessively high engine speed on a downhill road
 Discuss Question
Answer: Option A. -> Overheating of the fluid due to frequent brake application
Question 1197. The power source for a brake booster is
  1.    Exhaust manifold pressure
  2.    Electricity
  3.    The pressure difference between the atmospheric pressure and the vacuum pressure in the intake manifold
  4.    Hydraulic pump
 Discuss Question
Answer: Option C. -> The pressure difference between the atmospheric pressure and the vacuum pressure in the intake manifold
