Method for operating internal combustion engine in vehicle, involves actuating intake and exhaust valves of cylinder in compression stroke such that valves are opened during time period from beginning of compression stroke
Method for operating internal combustion engine in vehicle, involves actuating intake and exhaust valves of cylinder in compression stroke such that valves are opened during time period from beginning of compression stroke
The method involves igniting the fuel-air mixture in combustion chamber of one cylinder (2) of internal combustion engine (1) when the cylinder is in combustion stroke. The compression of air in another cylinder of engine is performed when another cylinder is in compression stroke. An intake valve (3) and an exhaust valve (4) of cylinder in the compression stroke are actuated such that the valves are opened during a time period from the beginning of the compression stroke. Independent claims are included for the following: (1) a device for operating internal combustion engine; (2) an engine system; (3) a computer program stored in electronic memory medium for operating internal combustion engine; and (4) an electronic control device comprising electronic memory medium for operating internal combustion engine.
