ABSTRACT:
A multi-cylinder 2 cycle engine having n cylinders has fuel injected and ignited at (n-1).times.360
crank angle intervals. This induces the situation wherein combustions occur in each cylinder at n-1 cycle intervals. This provides at least one piston stroke for each cylinder during in which no combustion takes place and fresh air is pumped through the combustion chamber in a manner to scavenge residual combustion gases therefrom.
