Basic Vehicle Technologies 2: Drivetrains and Environment Exam Questions And Answers

How does hill descent control assist the driver when traveling down steep hills at very low speed? - ANS Applies braking action to individual wheels How is Nissan becoming a global leader in zero-emission mobility? - ANS Engagement with more than 80 zero-emission partnerships worldwide Launched LEAF, the first 100% electric mass-market zero-emission car in 2010 Promoting recycling parts used in vehicle production How does a Helical Limited-Slip Differential compare to a viscous system? - ANS More sensitive to torque Not affected by temperature Responds more quickly Not dependent on components that can wear What are the ways to charge the Nissan LEAF? - ANS Standard charging with 220/240V utility service Quick charging with commercial high-voltage service How are Nissan's truck and SUV 6-speed manual transmissions different from manual transmissions in other vehicles? - ANS They re a very low 1st gear ratio that enhances off-road and towing capability 100% of the torque from Nissan LEAF's electric motor is available at ____ mph. - ANS 0 Nissan manual transmissions use double- or triple-cone synchronizers on the gears that receive the most use, which ________. - ANS -Enhances the durability of the transmission -Allows gears to mesh during shifting without grinding What does hill start assist do? - ANS Keeps brakes applied so the driver can transition from the brake to accelerator without the vehicle rolling backward What does hill descent control operate? - ANS Only in 4H or 4LO When activated by the driver Below 15 mph Which of these technologies helps to reduce vehicle emissions? - ANS Direct injection gasoline Turbocharging Advanced electronic engine control module ECM What does a transmission interlock do? - ANS Prevents the transmission from engaging accidentally What is overdrive? - ANS Gear in which the output of the transmission turns faster than the input What's the benefit of a limited-slip differential? - ANS Automatically distributes power to the drive-wheel that has the most grip Improves traction on slippery road surfaces How does D-step tuning affect CVT operation? - ANS Simulates shifts in certain driving situations The 2-range CVT combines conventional CVT belt operation with _______ to significantly increase the range of available drive ratios. - ANS An auxiliary gear What are the advantages of D-step tuning? - ANS Provides a more natural feel during rapid acceleration Relieves the engine noise of constant high-rev acceleration What does the regenerative braking do? - ANS Converts normally wasted energy from conventional braking into electric power Works with the friction brakes to create outstanding stopping power What's the benefit of overdrive? - ANS Allows the vehicle to operate more quietly and efficiently Promotes a more comfortable, quieter ride Increases economy through better fuel efficiency What is meant by saying a manual transmission has a close-ratio design? - ANS There is less than a 25% difference between each successive gear ratio A transmission interlock prevents ____. - ANS -Starting the engine unless the clutch pedal is depressed (manual transmission) -Shifting from Park unless the brake pedal is depressed (automatic transmission or CVT) How is Nissan's vehicle instrumentation designed for comfort? - ANS Prevents the transmission from engaging accidentally
