Question | Answer |
---|---|
88 Name three of the four components of a vehicle tracking system | on-board security control module, a minature transmitter and receiver, the global positioning satellite GPS system, a 24 hour monitoring/response center |
88 What happens if a vehicle with a tracking system is stolen? | monitoring center is notified, a signal is transmitted to activate the tracking system, that information from the GPS system pinpoints the location, the system transmits the location to the monitoring center |
88 Can a tracking system be easily hidden on a vehicle | yes they are usually small |
88 When can tracking systems provide protection? | carjacking kidnapping |
88 How does a DUI ignition interlock function? | sensors detect any alcohol in the driver's breath, if the driver is intoxicated the interlock disables the ignition system and triggers the horn to sound and lights to flash |
88 How does a night vison system help the drivers see? | When activated in bad weather or night the camer produces an image on the dash mounted monitor or a heads-up display on the windshield. the driver is then able to see through fog to detect oncoming dangers |
88 Describe how an electric brake caliper works | uses one or more servo motors to force the brake pads into the rotating brake disc to slow and stop the vehicle |
88 Are electonic brakes lighter or heavier than hydraulic brakes? | lighter |
88 Do electronic brakes reduce or increase fuel consumption? | reduce |
88 What kind of brake uses a dash mounted switch with an electic servo motor to mechanically apply the rear brake? | electric parking or electric emergency |
88 What kind of mechanism does a kinetic energy recovery system use? | either a flywheel mechanism or a battery to store the energy captured until it is needed. |
88 What would be the benefit of future vehicles having automatic tire wear adjustment systems? | would eliminate the need to rotate tires |
88 Name four alternate power sources, besides gasoline and diesel | hybrid vehicles, electric vehicles, hydrogen fuel engines, and flexible fuel vehicles |
Name an advantage of electric vehicles | reduce air pollution from burining fossil fuels |
88 Name a disadvantage to electric vehicles | large number of generating stations building enough generating stations would create pollution = nuclear power, coal, gas |
88 Describe a flywheel generator drive system | a direct whell drive design that eliminates the power lost from having to spin or rotate the transmission gearset and differtial assembly in heavy gear oil |
88 What produces little or no air pollution and is the same fuel that powers the sun? | hydrogen fuel |
88 It uses the power of the sun to generate electricity for propulsion | solar vehicle |
88 What regenerative braking converts the inertia of the moving car into electical energy to recharge the batteries? | regenerative braking system |
88 It combines hydrogen and oxygen to produce electrical energy | fuel cell |
88 What uses a large, high efficiency motor and large storage batteries to power the automobile? | electric vehicle |
88 What fuel can be created from animal fats and vegetable oils? | biodiesel fuel |
88 What are flexible-fuel vehicles? (FFV) | vehicles designed to operate on different types of fuel. Sensors monitor the efficiency and engine functions are adjusted |
88 What three fuels can gas turbine engines burn? | gasoline, kerosene, and oil |
88 Why are gas turbines not currently in use? | high manufactoring costs and poor fuel efficiency |
88 What will happen to the prices of petroleum based fuels if the reserves dwindle? | they will rise |
88 What is one plant fuel widely used? | ethonol |
88 Plant fuel research has led to the development of what kind of fuel? | biodiesell |
88 What kind of motor oil has been developed from farm grown plants and vegetables, and performs as well as crude oil based lubricants? | synthetic |
88 What is the most important factor in improving fuel economy? | vehicle curb weight reduction |
88 What materials are now being used to make vehicle body panels? | aluminum, fiberglass, carbon fiber |
88 What are inflatable door impact beams?How do they assist with safety? | a powerful pyrotechnic chargeis used to expand the metal beam so it balloons out to a larger diameter, it can withstand mor violent collisions from the side without intrusion into the driver or passanger seat area |
