Switching off the engine
Engine shutdown valve (distribution type injection pump) Off valve on the pump is to stop the engine. It consists of a magnetic core with a tight fit, and a return spring. When the coil 12 is no-volt voltage from the control unit EVE, spring firmly presses the core to the landing place, the supply of fuel mixture is stopped and fuel is no longer injected into the combustion chamber. After that, the control unit controls the actual stopping of the engine. If the engine does not work, it can only open overvoltage protection to ensure the injection system. If the engine continues to run, it is turned off by the amount of fuel regulator, and data on the faulty valve shutdown recorded in the computer's memory. Vacuum stop the engine (inline pump)

When you turn the ignition key to the off position electro-activated switch (Fig. 4.78) that works by vacuum, the vacuum pump. When stopped by the control unit is transmitted to the coil voltage, it draws back to the core, and both valves are switched off. The fuel pump starts to supply fuel for the bypass line back into the fuel tank. This rake pump returns to its original position, and the engine stops.
