Propane
True or False: propane is generally an environmentally friendly choice
False
what are the 2 main components of an electric vehicle?
battery pack, electric motor
air pollutants produced through tailpipe emissions when using gasoline/ICE
True or False: a safety concern for both propane and electric cars is that they are susceptible to catching on fire even when a crash has not occurred
True
True or False: Hybrid vehicles are subject to the same complications as gasoline and electric vehicles
True
What stages of manufacturing could contribute to the emission of greenhouse gases?
Production and Transportation
What does the electric vehicle not use that propane and hybrid vehicles use?
Internal Combustion Engine (ICE)
Where is the traction battery pack located?
Near the back (in between the 2 back wheels)
Lithium and Cobalt are used in which type of car?
Electric Vehicles
True or False: both hybrid and electric cars use cobalt and lithium
True
What is a new development of propane powered vehicles?
Direct Propane Injection
What determines the cleanliness?
Source of the battery (are fossil fuels used to produce the battery? Is it made with renewable resources?)
What does the range of the car depend on?
battery capacity
Which has higher fuel costs?
Which is more generally affordable?
Hybrid Vehicles
What is a non environmental concern regarding propane powered vehicles?
highly flammable, possibility of suffocation via high gas concentrations
What are the main environmental costs of electric vehicles?
Main environmental cost comes from production of emissions associated with extraction, processing, and distribution of primary energy sources used for electricity production (well-to-wheel)
What are the 4 main components of an electric vehicle?
battery, electric motor, gasoline tank, internal combustion engine
How are fires started in an electric vehicle vs a propane vehicle?
Electric: Short-circuits within an EV can shift, which can reignite a previously managed fire due to stranded energy. OR Battery defect
Propane: propane is highly flammable so propane leaks in combination with a flame/fire source
What do hybrid vehicles have that negatively impacts the environment that electric vehicles don't have?
tailpipe emissions
How are cold start problem fixed with the use of propane powered vehicles?
the fuel's mixture (propane and air) is completely gaseous when entering the engine's combustion chamber, and propane engines do not require an enriched fuel mixture during cold-weather startups the way other, liquid-fueled engines do.
What is regenerative braking?
electric motor in an electrified vehicle can be used to slow the vehicle and capture energy in the process, which would normally be lost
What is an Idle Stop-Start?
When vehicle comes to stop, engine temporary turns off to save fuel, restarts once driver releases brake pedal
Which has a higher fuel economy?
Electric because they do not suffer the same loss of energy that an ICE does, electric cars conserve and reuse energy.
How much does fuel costs for hybrids? For electrical?
(cents per mile)
Hybrid: 6-8 cents/mile
Electric: 4-5 cents/mile
