Abstract: An engine includes a fuel injector, an atmospheric pressure sensor, and an engine controller coupled to the fuel injector. The atmospheric pressure sensor detects the atmospheric pressure. The engine controller includes a first control device and a second control device. The first control device is configured to determine whether the engine is in a steady state or a transient state. The second control device is configured to calculate a fuel injection timing in the steady state, a the fuel injection timing in the transient state, and an atmospheric pressure correction process for correcting the fuel injection timing on the basis of the atmospheric pressure. The atmospheric correction process is performed only in the steady state to avoid redundancy. The engine controller outputs a final injection timing to the fuel injector as a result of the calculated fuel injection timing and the calculated atmospheric correction process.

Abstract: The objective of the present invention is to provide an engine with improved startability and stable operation regardless of the driving environment and usage conditions. The engine is equipped with a control means, which calculates a standard injection timing on the basis of the target rotational frequency of the engine and a standard injection amount, that is, the amount of fuel injected, and which corrects the standard injection timing using at least one correction amount. A fuel injection control unit calculates a cooling water correction amount on the basis of the target rotational frequency of the engine, the standard injection amount, and the cooling water temperature, and when the cooling water temperature is less than a first prescribed temperature the control unit corrects the standard injection timing using only the cooling water correction amount.

Abstract: An engine includes a fuel injector, a state determination unit, an atmospheric pressure sensor and an injection timing control unit. The state determination unit determines whether an engine state is a steady or transient state. The atmospheric pressure sensor detects the atmospheric pressure. The injection timing control unit performs a steady process for calculating a fuel injection timing in a steady state, a transient process for calculating the fuel injection timing in the transient state, and an atmospheric pressure correction process for correcting the fuel injection timing on the basis of the atmospheric pressure. The injection timing control unit changes either whether or not the atmospheric pressure correction process is performed or the contents of the atmospheric pressure correction process, depending on cases when the engine state is the steady or transient state.

Abstract: A link connectivity verification message to recognize a physical link connection state is transmitted from the WDM to the PXC on a C-plane. The PXC transmits a link connectivity verification ACK message including information representing a physical link connection state, and the WDM transmits a cross-connect instruction message to cross-connect a transmission side and a reception side of a port (port 1) of the PXC. Probe light transmitted from the port (port a) of the WDM is turned back by a cross-connect of the port (port 1) of the PXC. The WDM receives the probe light to verify a link connectivity.

Abstract: A propulsion apparatus for synchronizing the revolution speeds of a plurality of engines, each engine having a screw propeller shaft. A single regulator lever synchronously adjusts a revolution speed of the propeller shafts of the engines. When an output rpm of one of the engines has dropped, a control means lowers the revolution speed of the propeller shafts of the remaining engines to a revolution speed which is synchronized to the revolution speed of the propeller shaft of the engine whose rpm has dropped. Synchronization of revolution speeds of the remaining engines with the engine having reduced output rpm is terminated if the output rpm of that engine falls below a predetermined threshold.
