THE GENERAL DATA

Multidot system of injection of fuel Simtec of 56.5 engines of 1,8 and 2,0 l

1. The gauge of temperature of air arriving in the engine
2. A measuring instrument of a stream of air
3. A pressure regulator
4. A potentiometer throttle заслонки
5. The gauge of a cranked shaft
6. The step-by-step engine of management of idling turns
7. The camshaft gauge
8. The detonation gauge
9. System of catching of steams of fuel
10. The ignition block
11. The gauge of temperature of a cooling liquid
12. System of repeated burning of the fulfilled gases

The system of injection of fuel Simtec 56.5 is identical to system Multec-S established on engines DOCH of 1,6 l. Unique difference of system consists that instead of the gauge of measurement of absolute pressure in an inlet collector the measuring instrument of a stream of air is established.

Additional feature of system Simtec is that the path of giving of air in the engine has variable length to guarantee peak efficiency on high frequencies of rotation of the engine and a capacity maximum on low frequencies of rotation of the engine. The inlet collector is divided into two paths of various length. Each path of an inlet collector is equipped by the valve. The valve copes block ECU through the electromagnetic valve and a vacuum diaphragm.

On frequencies of rotation of engines less than 3 600 rpm valves remain closed and air arriving in the engine should go on a long path that leads to twisting moment increase.
On higher turns of the engine block ECU switches the electromagnetic valve and vacuum influences a diaphragm which opens a short path for air giving in the engine.
