Internal combustion engine with a continuously operating injection system comprising a warm-up control device and a fuel distributor

摘要

This internal combustion engine (1) with a continuously operating injection system (4) comprising a warm-up control device (6) and a fuel distributor (5) also has a device (9) for controlling the ratio of the proportions of fuel and air fed to the internal combustion engine (1), this device (9) having an exhaust-gas measuring probe (10) exposed to the exhaust gas from this internal combustion engine (1) and a control unit (11), which is connected to a timed-sequence valve (12) connected to the fuel distributor (5). In order to ensure that, in the event of a failure of the exhaust gas measuring probe (10) and/or of the timed-sequence valve (12) or the control unit (11), the internal combustion engine (1) functions reliably without excessive fuel consumption, a signal from the control unit (11) influences a relay (21) in such a way that a solenoid valve (16) opens a bypass line (15) connected into a return line (8) and into a control pressure line (7) of the warm-up control device (6) and reduces the control pressure in order to correct the leaning of the air/fuel ratio in the mixture. <IMAGE>
