A ship powered by an internal combustion engine (1) and an electric motor (2) connected to a propeller (3) powered by surplus electric power obtained by a thermal discharge recovery system has a controller including a feedback control section for controlling a base amount of fuel injected to the internal combustion engine (1) based on the difference between the target number of rotation of the propeller given by the operator and the real number of rotation, and a feed-forward control section having a means (25) for calculating an overall power output and a means (26) for calculating a correction in the amount of fuel injected to the internal combustion engine based on the overall power output and the number of rotation of the propeller. The base amount of fuel is corrected by subtracting the correction obtained by the feed-forward section from the base amount of fuel calculated by the feedback control section whereby preventing a rapid change in the speed of the ship due to rapid change in ship loads.

摘要:
The minimum value for the degree of opening of a wastegate valve (24), wherein the flow volume of exhaust air flowing via a wastegate port (22) when the degree of opening of the wastegate valve (24) is changed toward the open side stops increasing, is defined as a first prescribed degree of opening. An electronic control device (50) controls the degree of opening of the wastegate valve (24) on the basis of the engine operating state, and when the vehicle is running steadily at a high speed, that is, when the degree of opening of the wastegate valve (24) which has been set on the basis of the engine operating state is equal to or greater than the first prescribed degree of opening, the degree of opening of the wastegate valve (24) is varied between values equal to or greater than the first prescribed degree of opening.
摘要:
An integrated system and method for driving a CO 2 compressor to densify CO 2 captured from the exhaust gas stream of an internal combustion engine on board a mobile source of CO 2 includes operating a turbine that is operatively connected to the power input or drive shaft of the CO 2 compressor, and operatively connecting a motor-generator to the turbine for (a) recovery of any excess power when the turbine-generated power exceeds the CO 2 compressor power demand and (b) providing supplemental power when the turbine-generated power is insufficient to meet the CO 2 compressor power demand.
