QUESTIONS AND
ANSWERS (A+)
Mixture of Gas and Air
(the fuel mixture) - √Answer>What does the
Internal Combustion engine burn?
Quiz :1. Intake
2. Compression
3. Power
4. Exhaust - √Answer>What are the 4 strokes that
make up a cycle?
(in car engine)
Quiz :Intake - √Answer>This valve opens as the
connecting rod pulls the piston down, drawing the
gas/air mix into the cylinder
Quiz :Compression - √Answer>The valves are
closed. The connecting rod pushes the piston up,
compressing gas/air mix
,Quiz :Power - √Answer>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 - √Answer>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 - √Answer>The name for cylinders
that are arranged in one row
Quiz :V - √Answer>The name for cylinders that
are arranged in two rows
Quiz :Four-stroke, one-cycle engine -
√Answer>Most people refer to engines as four-
cycle engines but this is false; what are they really
called?
Quiz :Tachometer - √Answer>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 -
, √Answer>What must happen in order for the cycle
to happen at all?
Quiz :Carburetors - √Answer>___ 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 - √Answer>___ have replaced
carburetors on newer cars to perform the air/fuel
mixture function.
Quiz :Fuel Injector - √Answer>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 -
√Answer>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 -
√Answer>What does the EFI computer do?
Quiz :Throttle - √Answer>___ is mechanically
connected to the carburetor
OR
