Abstract: The method according to the invention is based on the discovery that the pollutant emissions in the first minutes of operation of an internal combustion engine also depend on the preceding operation and switching off procedure. It is suggested to subject the internal combustion engine and the catalytic converter to a cleaning or a scavenging phase before the standstill of the motor. With this cleaning or scavenging phase the movement of the internal combustion engine is still maintained for a certain time before standstill of the motor either by sparking or by an external drive and at least temporally in at least individual cylinders of the internal combustion engine the supply of fuel is interrupted and exclusively air is delivered. By way of this it is achieved that the remaining pollutants accumulated in the internal combustion engine are supplied to the catalytic converter which is still at the operating temperature and the catalytic converter is enriched with oxygen.

Abstract: Upon starting instruction of a compressor before the compressor is started, a pressurized water jet line 20 is opened and pressurized water is jetted to the inside of the compressor. By this manner, a dry operation with rotors and a mechanical seal kept in a dry state is definitely prevented and the compressor can be started even after it is stopped for a long hour. Further, the compressed air is supplied to the inside of the water tank, and the water from the water tank is jetted to the inside of the compressor by its pressure. The compressed air ejected from the water tank is cooled below a saturation temperature of water content and the water content thereof is condensed and separated. The separated water content is supplied to the inside of the compressor, and an excess circulating water is discharged from the water tank. Thus, a long hour continuous operation can be performed without replenishing water.
