FUEL INJECTION OutlineFuel injection control can be roughly divided into the following four types of control: 1) Fuel injection quantity control, 2)fuel injection timing control, 3) fuel injection rate control, 4) fuel injection pressure control.

9 Basic control content is iden-tical to that contained in the general edition MANUAL . However, the fuel injection timing control injection patterns is dif-ferent for the LAND CRUISER 70. The following is an explanation of the injection Injection PatternFuel injection timing is controlled according to the duration the injector is energized. First, main injection timing is deter-mined, followed by timing determinations for pilot injections 1 and (After Warm-Up)Start-Up (When at Low Temperature), Normal Operation5 )8ST (IEH 'IRXIV 8(' 4 MPSX -RNIGXMSR1 EMR -RNIGXMSR-RXIVZEP5 )8ST (IEH 'IRXIV 8(' 4 MPSX -RNIGXMSR 4 MPSX -RNIGXMSR 1 EMR -RNIGXMSR-RXIVZEPO peration Section1 147.
