What combines the suspension spring and shock absorber into one unit?
wheel hub |
|
strut |
|
knuckle |
|
wheel cylinder |
Because a compressed spring will extend violently, shock absorbers must be used to dampen the spring’s compression and extension cycles. Struts combine the spring and shock into one unit
Opposed cylinder designs feature two rows of cylinders that are placed at what angle to each other?
45° |
|
90° |
|
180° |
|
270° |
Opposed cylinder designs place cylinders flat in two rows 180° opposite each other with a single crankshaft running between them.
The __________ splits engine power between the front and rear axles of four-wheel drive vehicles.
universal joint |
|
transfer case |
|
master cylinder |
|
transmission linkage |
The transfer case splits engine power between the front and rear axles of four-wheel drive vehicles.
What is the primary difference between internal and external combustion engines?
the air-fuel mix for optimum combustion |
|
the type of fuel used |
|
how the fuel is ignited |
|
where the power is developed |
The primary difference between internal and external combustion engines lies in where the power is developed. In an internal combustion engine fuel is ignited and burned inside the same container where the power is developed while in an external combustion engine the fuel is ignited outside the engine and the resulting power sent to it.
Which of the following statements about fuel injection is false?
optimizes fuel delivery using various electronic engine sensors |
|
has replaced the carburetor as the primary fuel delivery system used in automotive engines |
|
atomizes fuel using high pressure and injects it into the engine |
|
relies on suction to draw fuel into the engine |
Fuel injection has replaced the carburetor as the primary automobile fuel delivery system. The main difference between the fuel injector and the carburetor is that fuel injection atomizes the fuel by forcibly pumping it through a small nozzle under high pressure while a carburetor relies on suction to draw fuel into an accelerated intake air stream.
