摘要： For controlling the injection of fuel in a direct injected, multi-cylinder internal combustion engine (10) to smooth transients in engine output torque associated with a deceleration fuel cut-off mode of engine operation, in response to detected operating conditions, a transitional period is initiated, during which the injection of fuel into a varying portion of engine cylinders (CYL1 - CYL3) 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 (CYL1 - CYL3) 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 (CYL1 - CYL3) is interrupted. The rate of entry into the fuel cut-off mode is preferably fixed, while the rate of recovery is determined in accordance with the position of an engine control element (38) 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 (38).

摘要： A method and apparatus are described for increasing engine braking, when a crankcase scavenged two-stroke engine (10) 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 (60) is decreased, for a predetermined period of time. After this period of time elapses, the quantity of air inducted into the engine (10) is then increased. This is preferably accomplished by regulating the degree of opening of a throttle valve (24) disposed within the engine air intake system (22). The initial closing of the throttle valve (24) restricts air flow through the engine (10) 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 (24) is opened, after the lapse of the predetermined time, to increase the quantity of air inducted by the engine (10). 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： An engine control system is disclosed for reducing the hydrocarbon content in exhaust gas from a crankcase-scavenged, two-stroke engine (10) in the operating range near idle, with light operator-­induced engine loading. As operator demand for engine output power is increased, the control system increases the fuel per cylinder delivered to the engine (10), whilst restricting the supplied mass of air per cylinder to a value less than or equal to that flowing at unloaded engine idle, in said operating range. This is done by coupling a throttle pedal (56) to a throttle valve (52) in an air intake manifold (20) through a pivoted linkage system (60,62,64,66,68,70,72,74) which includes a lost-motion connection (72,74), which prevents movement of the throttle valve (52) until a predetermined displacement of the throttle pedal (56) has occurred. A computer (48) of the control system controls the fuel supply per cylinder in response to signals (PED) received from a potentiometer (84) monitoring all mobement of the throttle pedal (56). The control system also may include an air bypass passage (76) and a computer-controlled, solenoid-actuated valve (78) to further control the supplied mass of air in said operating range.

摘要： The mass of air M available for combustion within a cylinder 14 of a crankcase scavenged two-stroke engine 10 is obtained by estimating the mass of air M trapped within a crankcase chamber 18, prior to its transfer to the associated cylinder combustion chamber 40. The estimate for air mass is derived from the product of pressure P of the air in the crankcase chamber 18 and the crankcase chamber volume V at a selected engine cycle position during that portion of the engine cycle when the air is trapped and undergoes compression within the crankcase chamber 18 divided by a factor containing the trapped air temperature T at the selected engine cycle position.
