<p>Components, eg a turbocharger, of an engine may be damaged when the engine is started whilst it is not sufficiently lubricated. The disclosed method and apparatus may facilitate improved protection against such damage to the components of an engine by priming the engine lubrication pressure for a period of time before starting the engine if, when an engine start is demanded by the operator, a measured engine lubricant pressure is below a threshold value. This may result in better lubrication of the engine before it is turned on, and consequently the engine components may have an improved lifespan. Priming the engine lubrication pressure may be performed by cranking the engine with the fuel injectors turned off. The lubricant pressure threshold may be determined by considering at least one of barometric pressure, engine coolant temperature and air inlet temperature. Engine speed may be limited for a period after starting.</p> |
