Vacuum Pump Technology - Part Info

Vacuum pumps are used in vehicles where the necessary vacuum cannot be generated by the intake manifold, for example, direct injection and turbo engines with variable valve timing. The pump generates a negative pressure of between 750 and 850 ar (10 to 12 psi) by drawing air out of the vacuum system.
