| 摘要 |
The invention relates to a mechanical injection system for an internal combustion engine with air-flow sensing and a warm-up regulator serving for enrichment of the mixture in the warm-up phase, which regulator is connected on the one hand by a pressure line to the intake pipe of the internal combustion engine and on the other by a control line to a fuel distributor of a mixture control unit, and operates as a function both of the intake pipe vacuum and the temperature.
<??>In order to prevent handling faults in the warm-up phase of the internal combustion engine a pressure jump switch constantly operatively connected to the intake pipe vacuum is provided by means of which a control valve interrupting the connection from the intake pipe to the warm-up regulator can be actuated as a 3/2-way valve in the pressure line.
