These components first reduce the CNG pressure from 3,000-3,600
psi to about 100-210 psi, and then reduce pressure from 100-210 psi
down to about 30-40 psi at the intermediate stage.
fuel pressure regulators
fuel injectors
fuel lines
fuel filter


ANSWERS: fuel pressure regulators


Mounted to the top of the engine intake manifold, these
components meter fuel into the combustion chamber using a single,
large nozzle that allows for gaseous fuel flow instead of liquid fuel.
fuel pressure regulators
fuel injectors
fuel lines
fuel filter


ANSWERS: fuel injectors

, This component is located between the high pressure regulator and
the low pressure regulator, and protects the fuel injectors from
moisture, particulates, and wax.
fuel pressure regulators
fuel injectors
fuel lines
fuel filter


ANSWERS: fuel filter


Match each filter to its correct layer or element:

ANSWERS:
1. uses an epoxy tube surrounded by three coarse fiber layers to
trap dirt
2. removes dirt particles
3. coalesces contaminant particles into oil droplets
4. drains coalesced contaminants from the filter


What type of concern might the vehicle operator experience
related to the CNG cylinder, or tank?
fuel odor, fuel loss, or an inaccurate fuel level indicator reading
no-start condition and rough engine operation
illuminated instrument panel indicators, such as the Alt/Gas switch,
the fuel indicator light, and the MIL


ANSWERS: fuel odor, fuel loss, or an inaccurate fuel level indicator
reading

,Which of the following describes a failure of the solenoid tank
valve?
sticking - if open, the system cannot relieve pressure during service;
if closed, fuel cannot move from the tank into the system
failure to close - often the result of the driver's failure to replace the
valve dust cover after refueling
gas smell - the tank is not sealed when the engine is off, requiring
manual shut-off


ANSWERS: sticking - if open, the system cannot relieve pressure
during service; if closed, fuel cannot move from the tank into the
system


What is located on the tank and contains details such as inspection
dates, operating pressure, test pressure, recommended operating
temperature, and type of gas used?
data plate
Alt/Gas switch
pressure relief devices


ANSWERS: data plate


Inspect this for wax-like buildup; if plugged, it may result in a no-
start or rough engine operation.
fuel filter
fuel
emission control devices
fuel pressure regulation system
fuel injectors


ANSWERS: fuel filter

, Water contamination in this can freeze, holding valves open.

emission control devices
fuel pressure regulation system
fuel injectors


ANSWERS: fuel


Look for add-on equipment that can prevent electrical signals from
reaching components and modules.
fuel filter
fuel
emission control devices
fuel pressure regulation system
fuel injectors


ANSWERS: emission control devices


Pressure relief device melts at temperatures in excess of 212° F (100°
C), allowing tank to relieve pressure in case of fire.

fuel
emission control devices
fuel pressure regulation system
fuel injectors


ANSWERS: fuel pressure regulation system
