📊 Automobile Engineering
Q. The firing order in the case of a four-cylinder I.C. engine (inline) is given as
  • (A) 1-2-3-4
  • (B) 1-4-3-2
  • (C) 1-2-4-3
  • (D) none of the above
💬 Discuss
✅ Correct Answer: (C) 1-2-4-3

Explanation: The firing order for a four-cylinder internal combustion engine is typically 1-2-4-3, where the cylinders are numbered from the front of the engine to the back. This firing order is commonly used in many four-cylinder engines because it provides smooth and even power delivery, as each cylinder fires in a balanced sequence.

💬 Discuss
✅ Correct Answer: (B) Continually recharge the battery
📊 Automobile Engineering
Q. In a vehicle if there is no king pin offset
  • (A) Starting steering effort will be high
  • (B) Starting steering effort will be zero
  • (C) Wobbling of wheels will increase
  • (D) bracking effort will be high
💬 Discuss
✅ Correct Answer: (A) Starting steering effort will be high
📊 Automobile Engineering
Q. In a four stroke engine, for the combustion of one litre of fuel, the volume of air required would be approximately
  • (A) 1 cu-m
  • (B) 5 - 7 cu-m

💬 Discuss
✅ Correct Answer: (D) 9 - 10 cu-m
📊 Automobile Engineering
Q. The number of revolutions per km for a free rolling tyre are less than that calculated from its static radius. This difference in number of revolutions is due to
  • (A) forces in the contact area that cause slight forward of the tread
  • (B) hysteresis of the tyre materials which make the dynamic loaded radius somewhat larger than the static radius
  • (C) either of (A) and (B) above
  • (D) none of the above
💬 Discuss
✅ Correct Answer: (C) either of (A) and (B) above
📊 Automobile Engineering
Q. The reaction time of an average driver from recognizing an obstacle is taken as
