VTEC systems – the general information and check of a condition of components
Many of models of Honda cars are equipped with electronic system of correction of phases of a gazoraspredeleniye (VTEC).
Distinction between ordinary engines and the engines equipped with VTEC system, consists in a complete set and a principle of operation of the klapanny mechanism. A design of the block of the engine and all hinged knots and units, and also schemes of the organization of systems of greasing and cooling on both units are identical. Engine outwardly equipped with VTEC system differs existence from above on a cover of a head of cylinders of a convex inscription of the corresponding contents (VTEC).
The inlet camshaft is equipped with three cams for each of valves given by it. The special module of management in capacity (RSM), proceeding from the data arriving from information sensors defines what of sets of cams during each present situation should give inlet valves of chambers of combustion. On the basis of the analysis of arriving information of RSM includes or switches off VTEC system.
As the initial parameters defining functioning of VTEC the following is used:
a) Frequency of rotation of the engine (rpm);
At small turns of the engine both primary, and secondary inlet valves work from own cams and open on identical height and with identical duration, providing a good torque in the bottom range of turns and high speed of reaction to gas.
When there is a need for increase of return of the engine, yokes of primary and secondary inlet valves by means of the special hydraulic device with electronic control are blocked with an intermediate yoke. Thus duration and height of opening of both valves is defined by a form of the intermediate cam, differing bigger height and a smaller ostrokonechnost of lifting.
Check of a condition of components
Electromagnetic valve of blocking / датчик-выключатель pressure
The electromagnetic valve of blocking of the VTEC system, the including sensor switch of pressure is located in the left part of a back wall of the engine (from a partition of an impellent compartment).
Models 1994 and 1995 of вып.
Malfunctions in a contour of the electromagnetic valve of blocking of VTEC lead to registration of a code of malfunction (DTC) 21 in memory of the control unit. On the car dashboard the control lamp “Thus lights up check the engine”. Detailed information on DTC systems of self-diagnostics it is provided in Head of the Control system by the engine.
Failure of the sensor switch of pressure leads to the record DTC 22 and operation of a control lamp “Check the engine”.
Models since 1996 вып.
Refusal in contours of the electromagnetic valve or the sensor switch of pressure leads to operation of a control lamp “Check the engine” and records in memory of the DTC P1259 control unit. Reading of diagnostic codes needs the OBD II scanner (see. Head of the Control system of the engine).
