12.16. System of protection of the engine from an overload
Prevention The system of protection of the engine from an overload is applied to engine capacity restriction at failure of the reduktsionny valve of a turbonagnetatel. The sensor of pressure established in an inlet collector measures pressure and is switched at the pressure exceeding demanded value. The sensor of pressure switches off the valve which blocks vacuum in knot of the diaphragm established on the fuel pump. Thus the fuel pump reduces supply of fuel to size, as well as in the engine without a turbo-supercharging. In system of protection of the engine from overloads replacement of the sensor of pressure and the vacuum electromagnetic valve is possible only. PRESSURE SENSOR Removal
