Abstract:
Methods and systems are provided for compression heating of air. In one example, a method may include, during an engine start and prior to a first combustion event, deactivating cylinder exhaust valves while spinning the engine electrically and unfueled until a threshold intake air temperature is reached, and alternately activating and deactivating the exhaust valves of one or more cylinders to maintain the intake air temperature above the threshold temperature after the first combustion event. In this way, a temperature of an air charge may be increased, resulting in increased fuel economy and decreased vehicle emissions.

Claim (Index 11):
The method of  claim 10 , wherein the performing the compression heating includes disabling fueling to the one or more cylinders and deactivating exhaust valves of the one or more cylinders while intake valves of the one or more cylinders remain active.
