#CMT# #/CMT# The engine (1) has four cylinders (2), where each cylinder has two exhaust valves (4, 5) connected to exhaust lines (6, 7) in which turbines (8) of turbocompressors (9) are arranged, respectively. A junction (23) for supercharge air flows (21) of active compressors (14, 15) is arranged in downstream of the compressors. A valve (25) with an air flap (26) is controlled externally, and is arranged in downstream of one of the compressors and in upstream of the junction. The junction has an air regrouping space (22) in which the valve is arranged. #CMT# : #/CMT# An independent claim is also included for a method for operating an internal combustion engine. #CMT#USE : #/CMT# Internal combustion engine for use in a vehicle. #CMT#ADVANTAGE : #/CMT# The engine is configured such that engine operating states such as oil temperature state, are considered to obtain harmonious service characteristics of the engine, thus permitting harmonious management of exploitation of the engine without stressing the engine and its components in an inappropriate manner, and hence operating the engine in a reliable manner, and improving the service life of the engine. The air flap is configured such that pressure wave present in the turbines is avoided so as to avoid sudden development of torque for supercharging of the engine of the vehicle, by a driver, thus permitting the development of torque in the engine in a comfortable manner. The engine is configured such that proper and easy utilization of the compressor prevents the changing of torque that is unpleasant for the driver. The compressors establish dynamic pressure in the intake pipe in a progressive and rapid manner such that dynamics of the engine is not compromised. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an internal combustion engine comprising two turbocompressors in two exhaust lines, and a supercharge air junction that is provided with a valve and is controlled externally. 1 : Internal combustion engine 2 : Cylinders 4, 5 : Exhaust valves 6, 7 : Exhaust lines 8 : Turbines 9 : Turbocompressors 14, 15 : Active compressors 21 : Supercharge air flows 22 : Air regrouping space 23 : Junction 25 : Valve 26 : Air flap. |
