Bosch combined pump can perform two tasks with a single component. In diesel and modern gasoline engines with low intake-manifold vacuum, the mechanical vacuum pump supplies the vacuum required for pneumatic operation, e. g. brake booster, exhaust-gas recirculation valve, swirl actuator, wastegate valve on the exhaust-gas turbocharger and central locking system. The variable oil pump performs engine lubrication and it can provide the circuit with the right amount of oil in all situations with low torque absorption. It contributes to the reduction of fuel consumption and CO₂ emission by displacement adjustment.
