Handling during cylinder cut-out operation
* Reduced cylinder mode operation means to run the engine with the fuel injectors of 1 or more cylinders disabled electrically to reduce the number of effective cylinders. The purposes and effects of this operation are as follows.
1. This operation is used to find out a cylinder which does not output power normally (or, combustion in it is abnormal).
2. When a cylinder is selected for the reduced cylinder mode operation, if the engine speed and output do not change from the normal operation (all-cylinder operation), that cylinder has 1 or more defects.
The possible defects are as follows.
* Leakage from the cylinder head gasket
* Defective injection
* Defective piston, piston ring, or cylinder liner
* Defective valve mechanism (Moving valve system)
* Defect in electrical system
3. Since the common rail fuel injection system controls the injector of each cylinder electronically, the operator can perform the reduced cylinder mode operation easily with switches to find out a defective cylinder.
* See the section of “Special functions of machine monitor” when turning on the cylinder cut-out operation.
Handling during no injection cranking operation
* No-injection cranking means to crank the engine with the starting motor while all the injections are stopped electrically. The purpose and effect of this operation are as follows.
* Before the engine is started after it or the engine unit has been stored for a long period, the no-injection cranking is performed to lubricate the engine parts and protect them from seizure.
* See the section of “Special functions of machine monitor” when turning on the no injection cranking operation.
