If the ECU has no valid information about the engine temperature (due to a damaged sensor) the fuel mixture during engine start gets calculated incorrectly.

Not exact matches

Conventional cars use an air - fuel mixture in which all the oxygen and fuel is burned during combustion.

This is not a big deal when the engine is running (worst possible side - effect: higher fuel consumption), but can prevent the engine from starting as the engine reacts more sensitively to changes in fuel - mixture during the cranking phase.

Too much fuel during the start and warm up, but in normal operation the mixture is correct and it burns soot from the plugs.

This includes valves and related components required to allow the air - fuel mixture to enter the combustion chamber, seal the combustion chamber during compression and combustion, and evacuate exhaust gases when combustion is complete.

The expansion intake manifold uses the principle of oscillating air in the intake manifold during the cooler expansion phase, keeping the temperature of the fuel / air mixture lower than in the 911 Turbo.

During cruising or other stable, low - load driving conditions, the new engine utilizes a dedicated set of cams to close one of the intake valves and retard that valve's timing, exerting backpressure on the air - fuel mixture.
