  • Arrangement in - and method for starting - an internal combustion engine
    Patent number: 5704323
    Abstract: Arrangement and method for an internal combustion engine (2), preferably a vehicle engine (2) provided with a turbo unit (14), whereby a compressed air device (18), preferably a compressor driven by an electric motor, builds up the charging pressure and thereby raises the air temperature in the engine combustion chamber (4) before the engine (2) starts. The result is a reduction in the environmentally harmful discharges which may otherwise occur when starting, owing to incomplete combustion.
