Title:
AMMONIA ENGINE
Document Type and Number:
WIPO Patent Application WO/2020/195426
Kind Code:
A1
Abstract:
An ECU (10) in this ammonia engine (100) executes: first control in which, when a start-up signal is input, the degree of opening of a reforming throttle (32) is complete closure, and the degree of opening of a stop valve (38) is a predefined initial degree of opening; second control in which, with the degree of opening of the reforming throttle (32) being complete closure, a reforming injector (35) is made to inject fuel in a predefined fuel injection pattern; and third control in which, with the degree of opening of the reforming throttle (32) being complete closure, and on the basis of the amount of fuel injected in the second control and a predefined estimated displacement volume, a displacement time by which the remaining gas in a reformer is to be displaced by the fuel injected in the second control is calculated, and the degree of opening of the stop valve (38) is decreased such that the degree of opening of the stop valve (38) reaches complete closure no later than the displacement time.
