Mixture of Gas and Air (the fuel mixture)
Ans: What does the Internal Combustion engine burn?
Quiz 1. Intake
2. Compression
3. Power
4. Exhaust
Ans: What are the 4 strokes that make up a cycle?
(in car engine)
Quiz Intake
,Ans: This valve opens as the connecting rod pulls the piston down, drawing the gas/air mix into
the cylinder
Quiz Compression
Ans: The valves are closed. The connecting rod pushes the piston up, compressing gas/air mix
Quiz Power
Ans: The spar plug ignites the gas/air mix, forcing the piston down. That pushes down on the
connecting rod, turning the crankshaft; the crankshaft turns the flywheel, which keeps the
engine going
Quiz Exhaust
Ans: The ___ valve opens as the connecting rod moves the piston back up, pushing out the
exploded gases. The valves are times, of course, using pus rods attached to the camshaft.
Quiz Inline
Ans: The name for cylinders that are arranged in one row
Quiz V
Ans: The name for cylinders that are arranged in two rows
,Quiz Four-stroke, one-cycle engine
Ans: Most people refer to engines as four-cycle engines but this is false; what are they really
called?
Quiz Tachometer
Ans: Instrument in a vehicle the measures revolutions per minute; rpm
(e.g. when this displays 4,800 rpm, that means the engine is performing 4,800 cycles every
minute)
Quiz Fuel must be properly mixed with air and transported within the cylinder at the proper
time
Ans: What must happen in order for the cycle to happen at all?
Quiz Carburetors
Ans: ___ are used (pre 1990) to mix the fuel and air mechanically. As air moves quickly through
this, it creates a vacuum, which draws more and more fuel into the mixture
Quiz Fuel Injectors
Ans: ___ have replaced carburetors on newer cars to perform the air/fuel mixture function.
, Quiz Fuel Injector
Ans: The ___ acts as the fuel-dispensing nozzle. It injects liquid fuel directly in to the engine's air
stream.
(In almost all cases it requires an external pump)
Quiz Electronic Fuel Injection computer
Ans: EFI computer stands for ___?
Quiz Determines the amount of fuel entering the engine: receives information from the sensors
in the fuel, air, and exhaust system, and from that information, it determines how much fuel
the engine needs to operate at optimum levels
Ans: What does the EFI computer do?
Quiz Throttle
Ans: ___ is mechanically connected to the carburetor
OR
___ is electronically connected to the EFI computer
Quiz Advancing (opening) the throttle causes more fuel to be transferred to the carburetor or
the fuel injectors. The accelerator (gas pedal) is connected to the throttle by mechanical
linkages. The harder you push on the gas pedal, the farther the throttle is advanced (opened).
Thus, more fuel is transported to the carburetor or fuel injectors.
