GAS-DIESEL CONTROL SYSTEM Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention relates to fuel feed control systems of gas diesel engines equipped with in-line high-pressure fuel-injection pumps. Proposed gas diesel engine control system has centrifugal member with sliding sleeve, main lever installed for interaction with sliding sleeve, control lever connected through spring with main lever, fuel metering unit mechanically coupled with main lever through tie-rod and intermediate lever. One end of tie-rod is connected with fuel metering unit, and other end is connected with main lever through additional tie-rod and intermediate forked lever. System is furnished additionally with control member travel sensor installed on governor housing, electromagnetic sensor with core whose case is connected from one side with main lever, and core with fuel metering member is connected at other side to control electric circuit determining position of core depending on position of control member, mechanically connected by additional lever with main lever and transmitting force from main lever to gas gate of engine mixer. Electromagnetic valve acting onto case of electromagnetic sensor provides locking of fuel metering member to set igniting amount of diesel fuel. Invention makes it possible to create unified control system of gas diesel engine which does not require considerable change of design of standard governor and provides possibility of changing ignition amount of diesel fuel for operation at low loads and at idling.

EFFECT: improved design of fuel feed control system of gas diesel engine.
