Abstract | PCT No. PCT/AU86/00204 Sec. 371 Date Mar. 11, 1987 Sec. 102(e) Date Mar. 11, 1987 PCT Filed Jul. 18, 1986 PCT Pub. No. WO87/00579 PCT Pub. Date Jan. 29, 1987.A method of operating a two-stroke spark ignition engine (9) wherein the fuel is injected directly into the combustion chamber (22). The timing of the injection of the fuel is varied according to engine load and speed conditions. Under low load and speed conditions at least 80% of the fuel is injected after closure of the exhaust port (20) whereas under some high load conditions at least 80% of the fuel is injected before closure of the exhaust port (20). The method may also comprise adjustment of ignition timing so that, in conjunction with low load and speed conditions, ignition occurs at least 5 DEG of crankshaft rotation after commencement of fuel injection and up to 70 DEG before top dead center of the engine cycle. |
