Diesel Engines and Their Idling Operation

摘要

To reduce engine noise and roughness when the engine is idling the intake air may be throttled by a valve 10 and the cylinder heater plugs 2 switched-on. The valve 10 and plugs 2 may be controlled automatically in response to an engine speed detector 19, 20, the position of the fuel pump rack 14, an ambient temperature detector 46 and an engine coolant temperature detector 16. The engine speed and pump rack position may be transmitted hydraulically to control the valve and plugs, Fig. 6 (not shown).
