Abstract
By a lean burn operation, a highly efficient operation region is enlarged, the proportion of engine operation in a low torque condition is increased, and the proportion of motor operation using a battery is decreased. It is possible to provide a hybrid car of an engine-electric motor configuration which can effect a highly efficient operation without increasing the capacity of motor and that of battery.
