Abstract: When an output signal from a lid sensor (7) is received, and an oxygen sensor (33) is not yet activated, a control apparatus reads a map value corresponding to an alcohol content of 100% as the increase value based on a coolant temperature detected by a coolant temperature sensor (13), and calculates a target actual fuel injection time from that increase value and a base fuel injection time. After the oxygen sensor has become activated, the control apparatus calculates a fuel correction value to achieve the stoichiometric air-fuel ratio based on the output signal and the coolant temperature, then calculates a target actual fuel injection time from the base fuel injection time and the estimated value of the alcohol content that was calculated based on this fuel correction value, and corrects the fuel injection time so that it approaches this target actual fuel injection time.

Abstract: A method for determining if the driveability index of a fuel being consumed by an internal combustion engine differs from the driveability index of a fuel of for which the air-to-fuel ratio of the engine is preset. The method includes the steps: determining the speed of the engine; determining the load on the engine; determining the actual exhaust gas temperature of the engine; and computing a predicted exhaust gas temperature based on the speed, the load and the preset air-to-fuel ratio of the engine. The actual exhaust gas temperature is compared to the predicted exhaust gas temperature to determine if the difference between the actual exhaust gas temperature and the predicted exhaust gas temperature exceeds a predetermined value.

Abstract: In known adaptive processes for fuel tank ventilation, the last value of the load factor is stored and directly used as initial value of the load factor for fuel tank ventilation purposes when the process starts once again. In the process disclosed, the stored value is first multiplied by a resetting factor and the result of the multiplication is then used as initial value. The resetting factor depends on the fuel temperature and amounts to maximum 1. This process has the advantage of giving good regulation results from the start of the process when it is applied to an internal combustion engine that is stopped when the fuel tank ventilation gas contains a high proportion of fuel vapours and that is started once again when said proportion is low.

Abstract: In order to control and adjust the starting mode of an internal combustion engine (1), a method is provided wherein a rail pressure is compared with a threshold value when the starting process is activated. According to said comparison, a first or second mode is set, wherein the rail pressure (pCR) for the starting process is controlled in a first mode and adjusted in a second mode. According to the invention, once the second mode is initially set, it is maintained for the rest of the starting process. As a result, high pressure fluctuations caused by mode changes can be prevented in an effective manner.

Abstract: An oxygen sensor is mounted in an exhaust path of an internal combustion engine. The status of an exhaust gas is detected in accordance with the output of the oxygen sensor. The oxygen sensor incorporates a heater for heating an element of the sensor. In a region in which the temperature of the sensor element is below 300°C, an adsorbable species becomes adsorbed. In a region in which the exhaust pipe temperature is above 80°C, the adsorbable species becomes adsorbed remarkably. Power supply control is continuously exercised over the heater so as to maintain the sensor element at a temperature of 300°C or higher until the exhaust pipe temperature drops below 80°C after an internal combustion engine stop. The power supply to the heater is shut off after the exhaust pipe temperature drops below 80°C.

Abstract: An in-cylinder ion sensor (24) provides a signal representative of the air/fuel ratio of the charge mixture as an engine starts. The signal representative of the air/fuel ratio is used as a feedback signal for an electronic control unit (12) to perform cold-start closed-loop control during an initial operating period from a cold-start before an on-board oxygen sensor is able to warm up. After reaching a functional operating temperature, the oxygen sensor (30) provides a signal that is used as an adaptive calibration tool which allows the electronic control unit to calibrate the ion sensor signal and use that signal for controlling the air/fuel ratio during cold start operation.
