摘要： The timing for opening the exhaust valve is advanced by an angle that varies depending upon the load exerted on an engine and the rotational speed of the engine at the cold starting of the engine during a predetermined period of time after the complete combustion. The heat of combustion is positively discharged into an exhaust system and, hence, an oxygen sensor and a catalytic converter disposed in the exhaust system of the engine are activated more quickly.

摘要： Combustion pressure is detected using a cylinder pressure sensor, and a crank angle position corresponding to a centroid of combustion during a combustion period is obtained as a combustion centroid position, based on the detected combustion pressure. Combustion conditions are then detected based on the detected combustion centroid position. On the other hand, depending on operating conditions, a crank angle position corresponding to a centroid of combustion during a combustion period for the case where desired combustion conditions are obtained, is set as a target centroid position, and an engine control quantity then feedback controlled so that the combustion centroid position becomes the target centroid position. In this way, combustion conditions of an internal combustion engine can be detected to a higher accuracy than with conventional arrangements wherein combustion conditions are detected based on fluctuations in an indicated mean effective pressure and the like, which shows only a comparatively small change with changes in combustion conditions. Moreover if engine control is carried out with the combustion centroid position as an index, then engine control accuracy can be significantly improved.

摘要： Engine output fluctuations are detected based on combustion pressure, and a fuel supply quantity amended so that the output fluctuations approach a permissible limit value. The properties of the fuel being used, can be estimated based on the amendment level, using characteristics that the limit air fuel ratio for stable combustion becomes leaner as the fuel being used is more volatile. Then when the fuel being used is volatile, the target air-fuel ratio in the air-fuel ratio feedback control is made leaner, thereby improving fuel consumption and exhaust gas properties.

摘要： An air/fuel ratio control system for an internal combustion engine is effective for improving exhaust characteristics and fuel combustion efficiency. Air/fuel ratio control is carried out by monitoring combustion pressure and analyzing variations therein for frequencies indicative of surge torque. Upon detecting of such indications a map selection function selects data maps from memory for controling the air/fuel ratio to be gradually enriched according to a detected amount of surge torque. If the amount of surge torque is within a predetermined basic range, the system is active to perform lean control for reducing the air/fuel ratio such that the engine may always run as lean as possible without incurring torque loss due to an insufficiently rich air/fuel ratio.

摘要： A fuel delivery control apparatus for use with an internal combustion engine having a throttle valve located in an induction passage for controlling the amount of air to the engine. The engine is associated with an evaporated fuel purging unit having a canister adapted to accumulate evaporated fuel from a fuel tank. A basic value of the amount of fuel metered to the engine is calculated based on the sum of the amount of air supplied to the engine through the throttle valve and the amount of air supplied to the engine from the canister. The basic value is corrected by subtracting the amount of evaporated fuel introduced from the canister to the engine from the calculated basic value. The fuel metered to the engine is controlled based on the corrected basic value.
