    Abstract: An engine variable valve timing mechanism is controlled during engine starting to set valve opening overlap of intake and exhaust valves around 30° CA. In this case, internal EGR is actively conducted, fuel burning velocity within a cylinder becomes relatively slow and unburned fuel within the cylinder is emitted to an exhaust pipe to be post-burned. The temperature of exhaust gas is maintained high and catalyst converters in the cold state may be activated quickly by actively implementing such post-burning within the exhaust pipe. Further, ignition timing is retarded, the air-fuel ratio is controlled to a slightly lean ratio and the exhaust valve is advanced. The effect of raising the temperature of exhaust gas by post-burning may be realized more reliably by combining each of these controls.

    Abstract translation: 在发动机起动期间控制发动机可变气门正时机构，以将进气门和排气门的开阀重叠设置在30°CA附近。 在这种情况下，主动地进行内部EGR，气缸内的燃料燃烧速度变得相对较慢，并且气缸内的未燃烧燃料被排放到要被后燃烧的排气管。 通过在排气管内积极地实施这种后燃烧，废气温度保持较高，处于冷态的催化剂转化器可以快速启动。 此外，点火正时被延迟，空燃比被控制为稍微减速，排气门前进。 通过组合这些控制中的每一个可以更可靠地实现后燃烧提高废气温度的效果。

    Abstract: Motion recognition processes are disclosed, in particular for regulating the impact speed of an armature on an electromagnetic actuator with at least one electromagnet having at least one pole face (4) and connected to a controllable power supply, and with an armature (5) connected to a regulating element to be actuated which when power is supplied to the electromagnet, is moved against the force of a restoring spring (7) in the direction of the pole face of the electromagnet from a first switching position to a second switching position in which it stops against the pole face. At least one sensor (11) detects in a defined air gap zone of the pole face a progressive attenuation of the magnetic field as the armature approaches and generates a corresponding signal.

    Abstract: An ECU calculates an actual relative rotational angle in a VVT based on a crank angle signal sent from a crank position sensor and a cam angle signal sent from a cam position sensor. Furthermore, the ECU calculates a fundamental target relative rotational angle based on engine operating conditions. The fundamental target relative rotational angle is corrected by a factor responsive to the change of the air-fuel ratio. Thus, a control rotational angle fed to the VVT varies in accordance with the change of the air-fuel ratio so as to stabilize the combustion and improve the power output characteristics.

    Abstract: In a valve timing control for an engine having an electronic throttle control system, the response of a valve timing control mechanism is estimated by operating condition of the engine. In addition to controlling a relative rotation angle of the VVT, a throttle correction gain for correcting the opening angle of a throttle valve so as to be adapted to the response of the VVT is calculated. The throttle valve is controlled by the calculated gain. When the response of the VVT is slow, the opening angle of the throttle valve is corrected on the basis of the response. Thus, a rapid engine acceleration is suppressed, thereby preventing occurrence of misfire.

    Abstract: Electronic controls for compression release engine retarders of internal combustion engines which provide electronic signals to control hydraulic valves assembled in the hydraulic actuators of the retarders, to open engine exhaust valves to provide compression release events. The electronic controls may produce signals for both opening and/or closing the controlled valves. The electronic controls may monitor various engine operating conditions and/or parameters with one or more sensors distributed in the engine and vehicle in which the engine is installed. The timing of valve actuation, particularly that for compression release events, can be automatically modified responsive to the level of engine operating conditions and parameters. Various operating routines for the electronic controls are also disclosed.
