摘要： An engine system includes a valve operable to permit exhaust gas to flow from the exhaust manifold to the air inlet manifold of an engine for the purpose of reducing the noxious gas content of the exhaust. The setting of the valve is dependent upon the amount of fuel supplied to the engine by the pump. A hydraulic signal is generated and this is derived from a supply pump by way of a fixed orifice this pressure being applied to a control valve which regulates the pressure applied to an actuator including a spring loaded piston. A throttle which controls the amount of fuel delivered by the injection pump also forms a further adjustable orifice downstream of the orifice whereby the pressure downstream of the orifice is dependent upon the amount of fuel supplied to the engine.

摘要： An air heating system for a compression ignition engine comprises a combustion chamber which includes a burner through which fuel is supplied to the combustion chamber. A two stage fuel pump is provided to supply fuel to the burner with the output of the second stage being connected to the burner and the input of the second stage being connected to the output of the first stage. Valve means is provided to ensure that there is substantially no pressure drop across the second stage of the pump and control means is provided to control the speed of operation of the pump so that the rate of fuel delivery to the combustion chamber can be closely controlled.

摘要： An engine system includes a compression ignition engine having an exhaust gas recirculation system incorporating a spindle mounting a valve. A fuel pump having a fuel lever supplies fuel to the engine and the spindle is connected to a control means which reduces the amount of exhaust gas recirculated as the fuel supply to the engine is increased. The control means is slow acting and in order to reduce the amount of exhaust gas recirculated in the event of a rapid movement of the control lever in a direction to increase the fuel, a linkage is provided connecting the control lever to the spindle. The linkage incorporates a piston cylinder combination which transmits rapid movement of the control lever to the spindle only when the control lever is moved to effect an increase in fuel.
摘要翻译：发动机系统包括具有排气再循环系统的压缩点火发动机，该排气再循环系统包括安装阀的主轴。具有燃料杆的燃料泵向发动机提供燃料，并且主轴连接到控制装置，该控制装置减少随着向发动机的燃料供应而增加的再循环废气量。控制装置是缓慢作用的，并且为了减少在控制杆沿着增加燃料的方向的快速移动的情况下再循环的排气量，提供将控制杆连接到主轴的连杆。该联动装置包括活塞气缸组合，其仅在控制杆移动以实现燃料增加时才将控制杆的快速运动传递到主轴。
