  • Vehicle cold start system
    Patent number: 4628877
    Abstract: A lubrication system for internal-combustion engines having a mechanical-type oil pump and turbocharger. The system includes an auxiliary electrically operated oil pump, a first time-delay relay connected to the ignition system to energize the electrically operated oil pump for a first time period after the ignition is turned on to prelubricate the engine, and a second time-delay relay to energize the electrically operated pump for a second period after the ignition is turned off to lubricate the turbocharger.
