TH60923A - Method for determining the stroke interval of an internal combustion engine And timing devices that use the aforementioned methods - Google Patents

Abstract

DC60 (11/08/46) in order to provide a method for determining the stroke of the internal combustion engine in that Set the engine stroke Can be built accurately without the use of a cam angle detector and the engine can also be precisely controlled by Is highly consistent with The actual amount of air taken after Timing And the timing device using the aforementioned method, the imported pressure detector 21 detects the imported pressure being Made by making strokes The air is introduced into the intake pass 6 during engine operation 3 ECU 20 detects the lower limit of the stroke inlet pressure and reverses the detection flag. Detected is an open state. ECU 20 also detects engine 3's TDC (center-end) signal from speed detector 23 according to TDC signal detection while limiting detection flag. In the open state, ECU 20 determines that the detection time corresponds to the compression end hub in order to provide a method for determining the internal combustion engine stroke. Set the engine stroke Can be built accurately without the use of a cam angle detector and the engine can also be precisely controlled by Is highly consistent with The actual amount of air taken after Timing And the timing device using the aforementioned method, the imported pressure detector 21 detects the imported pressure being Made by making strokes The air is introduced into the intake pass 6 during engine operation 3 ECU 20 detects the lower limit of the stroke inlet pressure and reverses the detection flag. Detected is an open state. ECU 20 also detects engine 3's TDC (center-end) signal from speed detector 23 according to TDC signal detection while limiting detection flag. LOWER IN ON STATE ECU 20 determines that the detection time corresponds to the center of the compression end.

Claims (1)

1. The timing range method of the internal combustion engine is characterized by the detection of at least one upper end center (TDC) signal between one stroke. Of the engine and detection of limit values The lower of the inlet pressure is the cadence between the engine operating state, and the engine timing in relation to The detection time of the TDC signal and the detection time of the limit value The lower of the input pressure is the 2 stroke interval.
