Abstract:
A direct cylinder injected, internal combustion engine comprising an engine body defining at least one cylinder bore in which a piston reciprocates to rotate a crankshaft, a cylinder head affixed to one end of said engine body for closing said cylinder bore and defining with said piston and said cylinder bore a combustion chamber, an air induction device having a throttle valve for admitting an air charge to said combustion chamber, a fuel injector for spraying fuel directly into said combustion chamber for combustion therein, means for sensing rotational speeds of said crankshaft, means for sensing an opening degree of said throttle valve, and a control device adapted to control an amount of fuel injected into the combustion chamber in response to an output from said throttle valve opening degree sensing means, and said control device delaying the adjustment control under a condition that an output from said crankshaft rotational speed sensing means is within a predetermined range and the output from said throttle valve opening degree sensing means is beyond a predetermined value.
