摘要： A method of determining a rate of flow of a first gas in a pipe includes placing a flow-restricting device in the pipe such that the device and/or the pipe define a first channel section and a second channel section. The second channel section is disposed downstream from the first channel section. The first channel section has a first cross-sectional area. The second channel section having a second cross-sectional area less than the first cross-sectional area. A source of a second gas is provided in fluid communication with the second channel section. A low pressure in the second channel section is caused by an increased flow velocity and creates a flow of the second gas into the second channel section. A rate of a flow of the second gas into said second channel section is measured. A mathematical relationship between the rate of the flow of the second gas into the second channel section and the rate of flow of the first gas in the pipe is ascertained. The rate of flow of the first gas in the pipe is calculated based at least partially upon the rate of flow of the second gas into the second channel section and the ascertained mathematical relationship.

摘要： A control system for a diesel engine for creating an ON/OFF feedback signal for controlling engine-related functions includes a mechanical assembly involving a fuel injection pump, a governor for the fuel injection pump, a pair of cam stops as part of the governor and an electrically grounded moveable rack finger. One of the cam stops is a fixed stop which limits travel of the rack finger and thus limits fueling to a predetermined level. The only variable which determines fuel quantity for this full load cam stop is engine speed. The second stop which limits rack finger travel is an air-fuel cam stop which has two independent variables that determine the fuel limit. These independent variables are engine speed and engine boost pressure. The air-fuel cam stop is placed within a housing which is electrically isolated from the rest of the fuel pump and the engine. Once there is contact between the moveable rack finger and the air-fuel cain an electrical signal (ON) is created which may be used to activate or energize other engine-related functions such as shutting off EGR during air limited operation.

摘要： A gas flow network in combination with a highly turbocharged diesel engine for the blending of either EGR gas or blow-by gas from the crankcase vent with fresh charge air is disclosed. In the diesel engine assembly which incorporates the flow network for EGR gas, a venturi conduit and control valve combination is positioned between tile intake manifold and aftercooler and is connected to a flow line carrying the EGR gas. When the turbocharged diesel engine assembly is configured with a flow path for blow-by gas, the venturi and control valve combination is positioned between the intake manifold and aftercooler and is connected to a flow line carrying blow-by gas. These systems utilize a low static pressure at the narrow throat of the venturi so as to induce the flow of EGR gas or blow-by gas into the fresh charge air, the flow being controlled by the state of the control valve.
