The principle behind a hybrid electric vehicle is that it
A) runs with conventional fuel but the motor shuts off when going downhill.
B) has a battery-powered electric motor in addition to a conventional engine.
C) has a small nuclear reactor in addition to a conventional engine.
D) runs on its electric battery except when starting the engine or travelling at speeds in excess of 90 mph.
Question 2
The difference between a plug-in hybrid and an electric car is that the plug-in hybrid
A) will not operate unless continuously connected to an AC electrical source.
B) uses less carbon-based fuel than an electric car.
C) still uses an engine and needs fuel whereas the electric car runs entirely on its battery.
D) has a small battery and will run only 25 as far as an electric car.
The downward movement of the piston draws the air–fuel mixture into the cylinder through the ...
An engine will not run if the air–fuel mixture is either too rich or too lean.
Detonation is a secondary ignition of the air–fuel mixture. It is also called spark knock or ...
In this design, the fuel injector is at the top of the cylinder and sprays fuel into the cavity of ...
Exhaust emissions are very complex. When the air–fuel mixture becomes richer, some exhaust ...
