With the constantly fluctuating price of gasoline, more people are looking into hybrid cars. But it's a good idea to know what you're getting into before purchasing one. Take the hybrid car quiz and see how much you know about them.
The most common type of hybrid car combines the following:
- diesel and electric power
- gas and electric power
- biodiesel and electric power
In a parallel hybrid:
- A gas engine runs an electric generator.
- A gas engine and electric motor can each turn the wheels.
- The engine has no connection to the transmission.
In a series hybrid:
- An electric motor acts as a backup to a gas engine.
- A gas engine and an electric motor alternately turn the wheels.
- A gas engine turns a generator, not the wheels.
Small engines are more efficient than large engines because:
- They weigh less.
- It takes less fuel to fill the cylinders.
- both A and B
The electric motor in a hybrid car can also act as:
- a generator
- a fuel pump
- a cooling fan
Regenerative braking involves:
- nanofibers that repair the surface of brake pads
- reclaiming heat from the brakes and using it for power
- reducing the amount of friction necessary to slow a car
The Toyota Prius uses its gas engine to:
- get the car moving
- power the car at most speeds
- power the car at certain speeds beyond 15 MPH
In a Prius, the power split device connects the:
- gasoline engine, generator and electric motor
- gasoline engine, electric motor and power train
- gasoline engine, transmission and brakes
The benefits of a hybrid car include:
- reducing emissions
- improving gas mileage
- both A and B
You should avoid abrupt stops in a hybrid car because:
- Hybrids are very sensitive to sudden changes in motion.
- The engine has more time to collect energy.
- Repairs to regenerative braking systems are extremely expensive.
