A control apparatus of a transmission for a vehicle, which includes an electric generator provided between an engine and the transmission and regenerating electricity when torque is transmitted from a drive shaft of the vehicle via the transmission in a braking condition, includes a releasing speed measuring unit, an up-shifting operation allowing unit and an up-shifting operation restraining unit. The releasing speed measuring unit measures a releasing speed of an accelerator pedal. The up-shifting operation allowing unit is applied to allow an up-shifting operation under the accelerator pedal being released when a releasing speed of the accelerator pedal is lower than a first threshold value. The up-shifting operation restraining unit is applied to restrain the up-shifting operation under the accelerator pedal being released when the releasing speed of the accelerator pedal is equal to or lower than the first threshold value.

Combustion chamber structure for direct injection diesel engine
A combustion chamber structure for a direct injection diesel engine is provided which can increase recirculated amount of exhaust gas while avoiding generation of black smoke and deterioration of fuel efficiency as much as possible.
Disclosed is a combustion chamber structure for a direct injection diesel engine having a cavity 10 on a top surface of a piston 9. The cavity is concave to provide a majority of the combustion chamber. Fuel is injected from a center of a cylinder top radially into an inner periphery of the cavity 10 to self-ignite. A depression 24 is formed at an outer periphery of the cavity 10 and is sunken relative to the top surface of the piston 9 to provide a step. The depression 24 has a bottom with an outer periphery gradually rising radially outwardly in modestly curved surface to the top surface of the piston 9. The inlet lip 11 is formed at a position lower than the top surface of the piston 9 by an inner periphery of the bottom of the depression 24 and a combustion chamber wall 12 rising from a bottom of the cavity 10.
