Automobile Engineering Online Test – Multiple Choice Questions and Answers 1. The two rows of cylinders in a ‘V’ type engine are generally arranged at 45° 60° 90° 130° 2. The major purpose of an electronically-controlled automatic transmission is that this type of transmission reduces the number of automatic-transmission components reduces shift shock and achieves more efficient transmission of engine torque eliminates gear clutches eliminates the gear shift lever 3. The function of a second ring is that it is a compression ring and aids the top ring in sealing and cooling back up compression ring which will work in place of the top ring when it is broken cushion ring which prevents piston slap and knock back up oil control ring which will work in place of the bottom ring when it is broken 4. The ball joints are used on the tie-rod ends, because they reduce the amount of noise generated reduce the amount of sliding resistance can deal with movement of the suspension both vertically and in other directions improve the force transmission speed 5. The braking control type traction control system (TCS) generally operates in the speed range of less than 20 kmph less than 40 kmph less than 60 kmph more than 60 kmph 6. The number of exhaust manifolds in a V-6 engine are 1 2 3 4 7. The size of engine cylinder is referred in terms of its diameter and bore bore and length bore and stroke displacement and efficiency 8. If the spark plug deposit indicates black coating of soot, it indicates that the engine has been generally operating on too rich mixture too lean mixture stoichiometric mixture most economical mixture 9. The function of antilock brake system (ABS) is that is prevents nose dives during braking and thereby postpones locking of the wheels minimises the brake fade reduces the stopping distance maintains directional control during braking by preventing the wheels from locking 10. The air resistance to a car at 20 kmph is R. The air resistance at 40 kmph will be R 2R 3R 4R Loading … Question 1 of 10
