摘要： A system is disclosed for controlling the pressure in a pressurized air supply for an internal combustion engine having pneumatic direct fuel injection, wherein pressurized air from the supply is utilized to inject fuel held within a fuel injector directly into an engine cylinder, against opposing cylinder compression pressure, while the injector is opened during a cylinder injection period in the engine cycle. The system adjusts the duration of the cylinder fuel injection period in accordance with the sensed pressure in the air supply to maintain the air supply pressure above cylinder compression pressure during the injection period, thereby preventing the backflow of fuel through the cylinder fuel injector into the air supply.

摘要： A system for a vehicle includes a filtering module, an indicated mean effective pressure (IMEP) determination module, and a stuck mechanism indicator module. The filtering module generates engine speeds based on positions of teeth of a toothed wheel that rotates with a crankshaft and based on a crankshaft position signal generated by a crankshaft position sensor. The IMEP determination module determines an IMEP for a combustion cycle of a cylinder of an engine based on squares of first and second ones of the engine speeds during the combustion cycle. The stuck mechanism indicator module selectively diagnoses a fault in a variable valve lift (VVL) mechanism of the cylinder based on the IMEP.

摘要： An idle speed regulating system is described for an internal combustion engine operating according to a fuel based control strategy, wherein the amount of fuel delivered the engine is determined directly as a function of the demand for engine output power and the amount of air supplied to the engine is controlled as a function of the quantity of delivered fuel. The system senses the actual idling rotational speed of the engine, derives a desired idling speed for the engine, and reduces the difference between the desired and actual idling speeds by adjusting the flow rate of the quantity of fuel delivered to the engine as a function of the difference between the desired and actual idling speeds. More specifically, the rate of fuel flow is adjusted in accordance with the sum of an open-loop feedforward value, a closed-loop feedback value, and preferably an adaptive learning correction value.

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 crankcase chamber, prior to its transfer to a cylinder combustion chamber during the engine operating cycle. The estimate for air mass is based upon the polytropic behavior of a portion of the crankcase compression process, and the pressure, volume and temperature of the air at two predetermined engine rotational positions during the polytropic phase of compression. The volume of the air within the crankcase chamber is determined as a function of engine rotational angle, with crankcase air temperature being derived as a function of intake air temperature. Air pressure during the polytropic phase of compression is sensed with a pressure sensor disposed within the crankcase chamber. The estimate for air mass is corrected to account for air leakage and imperfect transference of the air between the crankcase and combustion chambers.

摘要： An engine control system includes a piston movement modeling module, a cylinder volume determination module, and a cylinder pressure estimation module. The piston movement modeling module models movement of a piston within a corresponding cylinder based on angular change of an engine crankshaft. The cylinder volume determination module determines a volume of the cylinder based on an angular position of the engine crankshaft and the modeled movement of the piston. The cylinder pressure estimation module estimates pressure in the cylinder based on the determined volume, an intake manifold absolute pressure (MAP), an intake valve timing, an exhaust valve timing, and an exhaust back pressure (EBP).
