Removal and InstallationNJEM0071CAUTION:
When installing bearings, pistons, or other sliding parts,
lubricate contacting surfaces with new engine oil.
Place removed parts such as bearings and bearing caps
in their proper order and direction.
When installing connecting rod nuts, and main bearing
cap bolts, apply new engine oil to threads and seating
surfaces.
Do not allow any magnetic materials to contact the signal
plate of flywheel.
Do not remove the signal plate at back.
Do not place the signal plate side facing under.
Handle with care so as not to damage the signal plate
[especially four places on protrusions for signal of crank
position sensor (TDC sensor)].
DisassemblyNJEM0072PISTON AND CRANKSHAFTNJEM0072S011. Remove engine. Refer to “ENGINE ASSEMBLY”, “Removal

time the valve remains open (injection pulse duration). The amount of fuel injected is a program value in the

inally designed. Both manufacturing differences (i.e., mass air flow sensor hot film) and characteristic changes
during operation (i.e., injector clogging) directly affect mixture ratio.
Accordingly, the difference between the basic and theoretical mixture ratios is monitored in this system. This is
then computed in terms of “injection pulse duration” to automatically compensate for the difference between
the two ratios.
“Fuel trim” refers to the feedback compensation value compared against the basic injection duration. Fuel trim
includes short term fuel trim and long term fuel trim.
“Short term fuel trim” is the short-term fuel compensation used to maintain the mixture ratio at its theoretical
value. The signal from heated oxygen sensor 1 indicates whether the mixture ratio is RICH or LEAN compared
to the theoretical value. The signal then triggers a reduction in fuel volume if the mixture ratio is rich, and an
increase in fuel volume if it is lean.
“Long term fuel trim” is overall fuel compensation carried out long-term to compensate for continual deviation
of the short term fuel trim from the central value. Such deviation will occur due to individual engine differences,
wear over time and changes in the usage environment.
FUEL INJECTION TIMING
Two types of systems are used.
Sequential Multiport Fuel Injection System
Fuel is injected into each cylinder during each engine cycle according to the firing order. This system is used
when the engine is running.
Simultaneous Multiport Fuel Injection System
Fuel is injected simultaneously into all four cylinders twice each engine cycle. In other words, pulse signals of
the same width are simultaneously transmitted from the ECM.
The four injectors will then receive the signals two times for each engine cycle.
This system is used when the engine is being started and/or if the fail-safe system (CPU) is operating.
FUEL SHUT-OFF
Fuel to each cylinder is cut off during deceleration or operation of the engine at excessively high speeds.
