For inline cylinder arrangements in an engine, how are the cylinders numbered?
alternating from the front of the engine to the back |
|
alternating from the back of the engine to the front |
|
sequentially from the back of the engine to the front |
|
sequentially from the front of the engine to the back |
Inline cylinder arrangements number cylinders sequentially (1, 2, 3, ...) front to rear.
What is the primary difference between internal and external combustion engines?
where the power is developed |
|
the air-fuel mix for optimum combustion |
|
how the fuel is ignited |
|
the type of fuel used |
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.
Another name for the powertrain control module is the __________ control unit.
transmission |
|
electrical |
|
engine |
|
universal |
The main computer or powertrain control module (PCM) uses pre-programmed software to analyze the input received from sensors and produce output signals to adjust vehicle performance and operation. (Engine control unit (ECU) is another name for the PCM.)
The fluid reservoir stores the __________ that the master cylinder uses to maintain hydraulic pressure.
brake fluid |
|
ethylene glycol |
|
brake oil |
|
air |
The fluid reservoir stores the brake fluid that the master cylinder uses to maintain hydraulic pressure.
The combustion chamber is enclosed by the:
piston ring |
|
cylinder head |
|
piston |
|
head gasket |
Cylinders act as a guide for the pistons that translate the heat energy of combustion into the mechanical energy necessary to move a vehicle. Piston rings seal the piston to the cylinder to contain combustion gases and also regulate the oil distribution between the piston and cylinder wall. A cylinder head closes in the top of the cylinder forming the combustion chamber which is sealed by a head gasket (head). The head provides space for air and fuel intake valves, exhaust valves, and mounts for spark plugs and fuel injectors.
