Ignition system - the general information and precautionary measuresOn models considered in the real Management two types of systems of ignition are used: system of contactless ignition with the distributor and without that - system of direct ignition (DIS).
Systems of contactless ignition with the distributor
The contactless system of ignition equipped models of 1.5 l, 1.8 l of 1993 ÷ 1996 вып., 2.0 SOHC l, 2.4 l of SOHC 1994 ÷ 1998 of вып., 3.0 l of SOHC and 3.5 l. Management of an ignition advancing in such systems carries out the special electronic block (ECU). On models of 1.5 l, 1.8 l, 2.4 l and 3.5 l the coil of ignition and the key transistor are built in in the distributor case, on models of 2.0 l of SOHC and 3.0 l of SOHC these elements are established separately.
At ignition inclusion tension of the battery moves on primary winding of the coil of ignition. At rotation of a shaft of the distributor alarm impulses from the onboard processor (PCM) are told to the key transistor of system of ignition that leads to periodic short circuit of the negative plug of primary winding of the coil (via the transistor) on weight. As a result of such interruptions in a secondary contour of the coil VV the tension transferred to spark plugs of the corresponding cylinders and providing timely ignition of an air and fuel mix in them is induced.
System of direct ignition (DIS)
The system of ignition of this type is used on models of 1.6 l, 1.8 l of 1997 ÷ 2000 вып., 2.0 DOHC l, 2.4 l of SOHC since 1999 вып., 2.4 l of DOHC and 3.0 l of DOHC. Management of an ignition advancing here, as before, carries out ECU or the onboard processor (PCM).
Into structure of system enter the sensor of a corner of turn/provision of a cranked shaft (CKP) on which signals the module of management traces the current position of pistons. Analyzing information arriving from the CKP sensor, ECU/PCM defines the current frequency of rotation of the engine and exercises administration of injection and ignition of an air and fuel mix in cylinders. One more component of system is the VMT sensor informing the module of management passing by each of pistons of the provision of the top dead point of the step of compression. Information arriving from the VMT sensor is used by the module at sequence definition (and frequencies) injection.
At ignition inclusion tension of the battery moves on primary winding of the coil of ignition. Signals arriving from the CKP sensor will be transformed by the management module to operating impulses of ignition and transferred to the key transistor. The transistor provides regular short circuit of the negative plug of primary winding of the coil on weight as a result of which in a secondary contour of the coil VV transferred to spark plugs tension is induced.
At service of systems of direct ignition it is necessary to observe special precautionary measures:
a) If the engine is not started, do not hold the ignition key continuously turned in the situation ON within more than 10 seconds in a row;
b) Watch, that connection of a tachometer was carried out strictly according to instructions of manufacturers, - some of let-out measuring instruments can not be suitable for use on these models;
c) At all do not allow grounding of contact plugs of coils of ignition on weight, - the slightest imprudence in this question can lead to an exit of components of system out of operation;
d) Do not disconnect the battery at the working engine;
e) Watch correctness of grounding of components.
