摘要： A method is described for controlling the injection of fuel in a direct injected, multi-cylinder internal combustion engine, to smooth transients in engine output torque associated with a deceleration fuel cut-off mode of engine operation. This is accomplished by detecting engine operating conditions that call for the initiation of a transition associated with the decelaration fuel cut-off engine operating mode. In response to the detected operating conditions, a transitional period is initiated, during which the injection of fuel into a varying portion of engine cylinders is then interrupted. When the transitional period is associated with entry into the deceleration fuel cut-off mode, the injection of fuel to a progressively increasing number of cylinders is interrupted. When the transitional period is associated with recovery from the deceleration fuel cut-off mode, the injection of fuel to a progressively decreasing number of engine cylinders is interrupted. The rate of entry into the fuel cut-off mode is preferably fixed, while the rate of receovery is determined in accordance with the position of an engine control element for adjusting the amount of torque developed at the engine output. Alternatively, the rate of recovery may be determined by the maximum rate of positional change of the engine control element.

摘要： A method is described for increasing engine braking, when a crankcase scavenged two-stroke engine is operated in a deceleration fuel cut-off mode. In response to the detection of operating conditions indicating engine operation in the deceleration fuel cut-off mode, the quantity of air inducted into the engine is decreased, for a predetermined period of time. After this period of time elapses, the quantity of air inducted into the engine is then increased. This is preferably accomplished by regulating the degree of opening of a throttle valve disposed within the engine air intake system. The initial closing of the throttle valve restricts air flow through the engine for a predetermined time, to maintain efficient catalyst operating temperatures in the engine exhaust system. During extended operation in the deceleration fuel cut-off mode, the throttle valve is opened, after the lapse of the predetermined time, to increase the quantity of air inducted by the engine. This results in increased engine braking, due to the additional work that must be performed in compressing the larger quantity of inducted air.

摘要： A method and means are described for determining the mass of air available for combustion within a cylinder of a crankcase scavenged two-cycle engine, without the use of a mass-air flow sensor. This is achieved by estimating the mass of air under compression within a crancase chamber, prior to its transfer to the cylinder combustion chamber. The estimate for air mass is based upon the integration of crankcase pressure over the interval of decreasing crankcase volume, while air within the crankcase is under compression. The volume of the air within the crankcase chamber is derived as a function of engine cycle position, with crankcase air temperature being derived as a function of intake air temperature. Air pressure during compression is monitored with a crankcase pressure sensor. The estimate for air mass is corrected to account for air leakage and incomplete transfer of the air between the crankcase and combustion chambers.

摘要： A method of changing an active cylinder count of an engine may include determining a vehicle vibration limit and a vehicle vibration level. The cylinder count may be modified (increased or decreased) based upon the vehicle vibration limit and the vehicle vibration level. The vehicle vibration limit may be based upon a vehicle speed, and a coolant temperature of the engine. The vehicle vibration level may be based upon at least one of a desired torque of the engine and a number of active cylinders of the engine. According to other features, the vehicle vibration level may be based upon a measured vibration level of a vehicle component.

摘要： An engine control system is disclosed for reducing the hydrocarbon content in the exhaust gas of a crankcase scavenged, two-stroke engine in the operating range near idle, with light operator induced engine loading. As operator demand for engine output power is increased, the system increases the fuel per cylinder supplied to the engine while restricting the supplied mass of air per cylinder to a value less than that flowing at unloaded engine idle.
