1, intake china pressure sensor
Intake china pressure sensor, used to
indirectly measure the air; throttle release high vacuum, throttle depressed
vacuum low; vacuum low when more fuel injection, the proportion of small and
medium load! It is easy to find it, throttle after looking for trace!
2, crankshaft position sensor
Crankshaft position sensor, its role no one
for; once the signal is lost, how to start the car without; at this time, the
computer silly eyes, I do not know which tube dead! The
3, camshaft position sensor
Camshaft position sensor, generally
installed in the distributor; if not installed in the distributor, camshaft
before and after looking for! It's work is very simple, specifically measured
cylinder deadcorn point; report the computer even finished, the order of the
order of fire spray, lack of computer to play it does not turn ... ...
4, throttle position sensor
Throttle position sensor, the load signal
from it; five operating conditions to keep in mind, four and it has a
relationship! Flap off is idle, the signal voltage zero; flap open large load,
the signal voltage of 4.8; not only control the engine, but also control the
rheizer!
5, heating type oxygen sensor
Heating oxygen sensor, exhaust pipe
measured oxygen; used to control the air-fuel ratio, zirconia is the
electrolyte, their own electromotive force; oxygen for a long time oil supply
dilute, the signal voltage 0.1; oxygen gas when the gas is thick, the signal
voltage 0.9; Oil, every 10 seconds in 8 change, if the change quickly change!
6, piezoelectric knock sensor
But the measured earthquake frequency (6 ~
9KHz), the ignition angle of the child back, detonated disappeared, the
ignition began to move forward; control the best point of ignition, the
ignition of the sensor, Always on the edge of the knockout area!
One of the characteristics of modern automotive
technology development is the increasing use of electronic control components.
The work of electronic automatic control depends on the information of the
sensor. According to statistics, the current general car about dozens of
sensors, high-class cars have more than 100 sensors.
