摘要： It is possible to suppress fluctuations of an air intake amount when the open degree of an air intake control valve is unknown. An engine (200) includes an impulse valve (224) common to all the cylinders arranged in the engine (200). The impulse valve (224) is arranged in a communicating tube (206) provided at the downstream side of a serge tank (205). An ECU (100) executes impulse valve drive control. In the control, the ECU (100) judges whether a rotation angle sensor (225) which detects the open degree of the impulse valve (224) has failed. If it is judged that the rotation angle sensor (225) has failed, the ECU (100) controls a drive motor (224C) and a drive circuit (224D) for driving a valve body so that a valve body (224A) of the impulse valve (224) rotates inside the communicating tube (206). Here, the rotor of the drive motor (224C) which defines the rotation speed of the valve body (224A) has an rpm which is set in accordance with the mechanical rpm NE of the engine (200).

摘要： The disclosed ammonia-burning internal combustion engine is able to supply ammonia and a highly combustible material, which is more combustible than ammonia, to a combustion chamber. When the amount of ammonia supplied to the combustion chamber (2) increases, or when the proportion of ammonia supplied to the combustion chamber in relation to the total amount of ammonia and highly combustible material increases, the operating parameters of the internal combustion engine are controlled in such a manner that the air-fuel mixture supplied to the combustion chamber combusts more easily. Thus, the decrease in combustibility of fuel supplemented with ammonia can be curbed.

摘要： The disclosed ammonia-burning internal combustion engine, which uses ammonia as fuel, is provided with an ammonia supply device (13) that supplies ammonia to a combustion chamber (5) and a heating/pressurisation device (28) that heats and pressurises ammonia that is suppled by the ammonia supply device. The heating/pressurisation device heats and pressurises ammonia using the energy generated in association with the operation of the internal combustion engine. Thus, high energy efficiency throughout the entire internal combustion engine or throughout an entire vehicle fitted with an internal combustion engine can be maintained while the temperature and pressure of the ammonia that is supplied by ammonia jet valves can be appropriately controlled.
