Fuel Systems
This injection system uses higher fuel pressure, typically found in more modern cars.
Direct injection
This component was responsible for ignition timing back in the days of carburetors.
Distributor
This is the name of the connector that is universal for all scan tools to connect to (after 1997)
OBD2
Gathering data from sensors and other inputs is the job of this component
ECU
Name the 4 strokes in the 4-stroke engine cycle in order.
Intake, compression, power, exhaust
This system uses a low pressure and high pressure pump, and sometimes has 2 sets of injectors.
Direct injection
This component provides voltage to the spark plug and causes the start of the power stroke/combustion process.
Ignition coil
This is the name for perfect air/fuel ratio, maintained by the ECU.
Stoichiometric / 14.7:1
The full name for a DTC
Diagnostic Trouble Code
In a circuit with 12 volts and 6 ohms of resistance, how much current will flow?
2 amps
This is the stroke in the 4-stroke cycle that the fuel injector fires in a port injection system.
Intake Stroke
The amount of voltage sent by the ignition coil to the spark plug
30,000-50,000
The throttle body, ignition coil, and fuel injector are all considered this type of component.
Actuators
This function allows us to see sensor data/voltages in a more visual way.
Graph
Name 3 components of an alternator.
Pulley, stator, rotor, rectifier, voltage regulator
This is the stroke of the 4-stroke cycle that the fuel injector fires in a direct injection system.
Compression stroke
This is the spontaneous ignition of the air/fuel mixture in the combustion chamber, without the use of the spark plug
Spark knock / detonation
As crankshaft speed increases, the spark plug will fire... (Timing advance)
Sooner
This is the number of computers in a current generation Toyota Tundra.
53
When did the Ford Mustang begin production?
1964 1/2
The amount of fuel pressure from the low pressure pump and the high pressure pump in order, in a direct injection system.
45-60, up to 3000
The ignition timing is delayed (retarded) if the ECU detects this.
Spark Knock
Not all scan tools can perform all functions. Some tests or checks must be performed by...
Dealership technicians / Scan tools
Sensors only need one connection due to this system that connects all the major computer modules.
CAN BUS
This year is the only year in the Corvette's history to have been "skipped".
1983
