15. The ideal diesel cycle consists of an isentropic compression process, a constant-pressure combustion process followed by an isentropic expansion process, and finally a constant-volume exhaust process. Based on the above description, which statement is false? (A) The isentropic expansion process is followed by a constant-volume exhaust process. (B) The isentropic compression process takes place before the constant-pressure combustion process. (C) The isentropic expansion process takes place before the combustion process in order to produce the work output. (D) The constant-pressure combustion process takes place between the isentropic compression process and the isentropic expansion process.
