Detecting and Preventing Two-Phase Flow To Gaseous Fueled Engines
A system can include a flow measurement device positionable in a flow path for measuring a property of the fuel flowing through the flow path and a shutdown device positionable in the flow path for controlling the fuel flow through the flow path. The system can also include a computing device that is communicatively coupled to the flow measurement device for receiving the fuel flow property and from which the presence of two-phase flow or multiphase flow can be detected. The computing device is also communicatively coupled to the shutdown device for controlling fuel flow through the flow path in response to the detection of two-phase flow or multiphase flow.
CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE, AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
A control apparatus for an internal combustion engine includes circuitry configured to control a fuel injector of the internal combustion engine to stop injecting fuel to reduce torque generated by the internal combustion engine during upshift. The circuitry is to acquire a target injection amount parameter corresponding to a target injection amount of the fuel to be injected by the fuel injector to operate the internal combustion engine based on an operation state parameter corresponding to an operation state of the internal combustion engine. The circuitry is to acquire a minimum injectable amount parameter corresponding to a minimum injectable amount of the fuel injectable from the fuel injector. The circuitry is to control the fuel injector to start injecting the fuel when the minimum injectable amount parameter exceeds the target injection amount parameter while the fuel injector is controlled to stop injecting the fuel during the upshift.
FUEL CONSUMPTION-MEASURING SYSTEM AND METHOD FOR MEASURING THE FUEL CONSUMPTION OF AN INTERNAL COMBUSTION ENGINE
A fuel consumption-measuring system includes a feed line, a first pump which pumps fuel from a tank via the feed line to a consumer, a fuel consumption-measuring device in the feed line, a first return line which branches off at the consumer and opens into the feed line between the fuel consumption-measuring device and the consumer, a second return line which branches off from the feed line between the first pump and the fuel consumption-measuring device which opens into the tank, a branch which leads from the feed line into the second return line, a heat exchanger, and a flow device arranged in the first and second return lines. The flow device provides an equal volume flow at an opening of the first return line into the feed line and at the branch leading from the feed line into the second return line.
SYSTEM AND METHOD FOR IDENTIFYING A POTENTIAL ENGINE STALL AND CONTROLLING A POWERTRAIN SYSTEM TO PREVENT AN ENGINE STALL
A system according to the principles of the present disclosure includes an engine stall module and an actuator control module. The engine stall module identifies a potential engine stall based on a speed of an engine and a rate of change in the engine speed. The actuator control module selectively adjusts an actuator of a powertrain system to prevent the engine from stalling when a potential engine stall is identified.
NON-CONTACT SENSOR DEVICE FOR ELECTRIC THROTTLE
This invention is related to a non-contact sensor device for electric throttle, comprising a body and a cover. A drive assembly is set in the body and has a shaft corresponded to the on/off state of a throttle valve. An adaptor is installed on the shaft, and a magnet element is set on the adaptor. A Hall element is set on the cover to correspond to the magnet element for detecting the rotation angle of the shaft, thereby knowing the air inflow value and the open angle of the throttle valve to control the fuel injection of fuel-air mixture.
Electric actuation of a valve based on knowledge of the closing point and opening point of the valve
A method for determining an effective injection time of a valve having a coil drive includes determining an opening time of the valve, determining a closing time of the valve, and determining the effective injection time of the electric actuation of the valve for an injection operation based on the defined opening time and the defined closing time.
Method for controlling an internal combustion engine
A method for controlling an internal combustion engine is disclosed. The method may include receiving knock data corresponding to knock levels over a time period. The method may also include determining from the knock data whether the knock levels change over the time period. Further, the method may include determining that a variation in the gas composition of the gaseous fuel supplied to the internal combustion engine has occurred when the knock levels change over the time period. In addition, the method may include adjusting an operating condition of the internal combustion engine to adapt a knock susceptibility of the internal combustion engine to the varying gas composition.
Optimizing diesel, reductant, and electric energy costs
Systems and methods to reduce operating expenses of a vehicle based on control of operation of a vehicle system. The system includes a controller. The controller is structured to receive one or more parameters comprising expense data, adjust operating expenses of a vehicle system based on the one or more parameters, and generate a command structured to adjust operation of the vehicle system responsive to the adjustment of the operating expenses.
Engine system control apparatus and vehicle
An engine system is mounted on a vehicle and includes an engine and a turbocharger. The engine system control apparatus includes: a driving state identifier that identifies a driving state of the vehicle from a plurality of driving states; a surge determiner that determines whether a surge condition as a condition under which a surge noise is generated is satisfied, based on the identified driving state of the vehicle and an operating state of the engine; and a variable nozzle controller that controls, based on the identified driving state of the vehicle and the operating state of the engine, an opening degree of a variable nozzle of the turbocharger to be varied in an open direction, upon determination by the surge determiner that the surge condition is satisfied.
System and method for controlling an engine based on piston temperature deviation
A system for controlling an engine based on piston temperature deviation includes a piston temperature estimation module that estimates a piston temperature based on engine operating conditions, a piston temperature deviation estimation module that estimates a deviation of the estimated piston temperature from a steady-state piston temperature, and an engine control module that determines an engine control parameter based upon the estimated piston temperature deviation.
