FORD FIESTA 2011MY WORKSHOP REPAIR MANUAL BACK TO CHAPTER INDEX TO MODEL INDEX Electronic Engine Controls — 1.6L Duratec-16V Ti-VCT 303-14B-18 303-14B-18 (85kW/115PS) - Sigma DESCRIPTION AND OPERATION Item Description A Higher engine speed B Lower engine speed 1 Zero transitions: Spacing small/amplitude large 2 Zero transitions: Spacing large/amplitude small flap position. The ignition timing is calculated taking both of these variables and the engine speed into account. It is based on ignition maps stored in the PCM. The ignition timing is adjusted according to the operating condition of the engine, for cold starting for example. The acceleration of the flywheel at each power stroke results in a change in the CKP signal. 3 During the power stroke, the combustion pressure acting on the piston causes an acceleration of the crankshaft and thus also of the flywheel.
This is apparent in the voltage curve from slightly higher frequencies and amplitudes of the CKP signal. The CMP sensor is used by the PCM for cylinder number one recognition so that the injection and ignition sequence can be determined. Based on the calculated camshaft position and information about the crankshaft position, the PCM is able to determine the correct ignition timing and the correct injection timing for each individual cylinder. Also it can accurately identify a cylinder that is showing a tendency to knocking combustion. The following provide the basis for calculating the ignition angle:. Engine speed Engine load. Powertrain Control Module KS signal The ignition angle has a major impact on engine operation.
It influences:. engine performance.
exhaust emissions and. fuel consumption Since propagation of the flame front in the air/fuel mixture always takes the same amount of time, the ignition of the air/fuel mixture has to take place earlier or later depending on the engine speed.
The higher the speed, the earlier ignition must occur. The higher the engine load, i.e.
The torque demand, the richer the air/fuel mixture, the longer the combustion period and the earlier the ignition. This ensures that maximum combustion pressure is achieved immediately after Top Dead Centre. 1 2 E96319 Item Description 1 Engine load. 2 Engine speed 3 Ignition angle The ignition maps were calculated in a series of tests. Particular attention is paid to the emission behaviour, power and fuel consumption of the engine. The ignition map is stored in the data memory of the PCM.

By adjusting the ignition timing it is also possible to influence the engine speed to some extent without having to change the throttle valve position. This has advantages for idling stabilization, as the engine speed and hence the engine torque respond far more quickly to a change in the ignition timing than to a change in the throttle valve position. Furthermore, the ignition timing can be changed much more quickly.
In order to keep the moment of ignition as close as possible to the knock limit and thus optimize the efficiency of the engine, a KS is installed on the engine; it records the mechanical oscillations of the engine and converts them into an electrical signal for the PCM. The engine load is determined by the PCM using the signal from the MAF sensor and the throttle 2011MY Fiesta 8/2010 G1075684en.
