Abstract (en)
A device (2) for controlling operation of aninjection engine (3) includes first and second sampling conduits (211,212), a pressure sensor (221), an electromagnetic switch (231) disposed to block and unblock fluid communication between the pressure sensor (221) and each of the first and second sampling conduits (211, 212), and an electronic control unit (241) electrically coupled to the pressure sensor (221) and the electromagnetic switch (231) and disposed to receive a crankshaft rotation signal. The electronic control unit (241) is configured to control the electromagnetic switch (231) so that the pressure sensor (221) may determine a negative pressure value of a selected one of first and second cylinders (31, 32) of the injection engine (3), and is configured to perform control for ignition and fuel injection in each of the first and second cylinders (31, 32) with reference to the negative pressure value and the crankshaft rotation signal.
