German patent No. 86,633 for Diesel's engine was issued in 1895; only the year is attested, and the March 1895 application was a separate filing.
In 1894 and 1895, Diesel filed patents and addenda in various countries; the German patent (No. 86,633) was issued in 1895, though no specific day is stated in the sources. On 30 March 1895, Diesel applied for patent RP 86633 for a starting process with compressed air — a separate filing, not the engine patent grant itself. The legacy row's 30 March date is therefore an application date, not the grant date. By June 1893 Diesel had adopted the constant pressure cycle after realizing his original cycle would not work.
