摘要： A booster circuit installed in a fuel injection device of an internal combustion engine, wherein malfunctions and characteristic changes of the booster circuit are detected, among which the detection distinguishes between decreases in capacity caused by deterioration or broken wires in a booster capacitor, and failures of a current monitor circuit, coil, externally connected fuel inj ection valve, and other components. The range of decrease in boost voltage when the fuel injection valve is opened is monitored, as is the range of increase per switch performed in order to restore the boost voltage. This makes it possible to detect malfunctions and characteristic changes of the booster circuit.

摘要： According to the invention, a particulate matter sensor (8) is installed in an exhaust passage (4) of an internal-combustion engine (2). A control unit (10) for this internal-combustion engine (2) detects a particulate amount in an exhaust gas through the exhaust passage (4) in response to an output from the particulate matter sensor (8). Further, the control unit (10) for the internal-combustion engine (2) forms a particulate layer on electrode surfaces of the particulate matter sensor by applying a particulate capturing voltage between the electrodes during a first period. Further, the control unit maintains the formed particulate layer during a second period. It is noted here that the phrase "maintain the formed particulate layer" means to include "maintaining the formed particulate layer as it is" and "inhibiting control to remove the particulate layer".

摘要： Generators and methods for shutting down generators in confined spaces. One generator includes an internal combustion engine, an alternator, a power outlet, and an electronic processor communicatively coupled to the engine. The electronic processor is configured to obtain an engine speed of the engine, and determine that the engine speed is below an engine speed threshold. The electronic processor is further configured to determine, in response to determining that the engine speed is below the engine speed threshold, that a predetermined number of a plurality of secondary parameters of the generator have crossed respective secondary thresholds. The electronic processor is further configured to shut down the generator in response to determining that the predetermined number of the secondary parameters have crossed the respective second thresholds.

摘要： A control device for a compression ratio variable internal combustion engine is provided with a compression ratio variable mechanism for changing an engine compression ratio in accordance with a rotational position of a control shaft, and a compression ratio detection unit that detects an actual compression ratio. In a predetermined engine operating condition (S11) such as immediately after an engine start, reference position learning operation for the compression ratio detection unit is carried out (S12) with the control shaft mechanically locked up at a predetermined reference position. During operation of the engine, even when the actual compression ratio is lost due to a communication error or the like (S13), or even when a difference between the actual compression ratio and a target compression ratio becomes greater than an assumed deviation due to some abnormalities (S14), the reference position learning operation is immediately carried out (S15), thereby enabling a quick return to a state where normal compression ratio control can be carried out.
