<P>PROBLEM TO BE SOLVED: To provide a jump spark ignition internal combustion engine for hybrid vehicle which can generate relatively large engine braking by suppressing increases in the vibration and noise of the jump spark ignition internal combustion engine when it cannot make a motor generator operate as a generator in performing vehicle deceleration. <P>SOLUTION: The jump spark ignition internal combustion engine incorporated into the hybrid vehicle together with the motor generator includes a machine compression ratio variable mechanism to increase an engine speed with an automatic transmission (step 109) when it cannot make the motor generator operate as the generator in performing vehicle deceleration (step 102), and to reduce a real compression ratio with the machine compression ratio variable mechanism (step 108). <P>COPYRIGHT: (C)2012,JPO&INPIT |
