In a hybrid vehicle including an internal combustion engine, an electric motor, a generator, a battery, and a catalytic converter disposed in an exhaust system of the engine, a determination is made as to whether a condition for stopping the engine is established, based on an operating state of the vehicle. Then, the fuel supply to the engine is cut off when the condition for stopping the engine is established, and a load (for example, a load of the generator) is applied to the engine so as to restrict rotation of the engine.

The side handle arrangement for a tool according to claim 6, wherein said collar is adapted to vary a torque setting of the tool by rotation of said collar. 10. A drill driver comprising: a housing; a gear case cover with a rear portion, a middle portion, and a front portion, the rear portion mounted to said housing; a torque adjustment collar rotatably mounted around said middle portion of said gear case cover; a spindle extending from said front portion of said gear case cover; a cap member mounted on said front portion of said gear case cover, said spindle extending through a forward end of said cap member; a chuck mounted to said spindle; and a side handle mounted to said cap member forward of said rotary collar. 11. The drill driver according to claim 10, wherein said side handle includes an annular mounting portion for connecting said side handle to an outer surface of said cap member. 12. The drill driver according to claim 11, wherein said annular mounting portion allows said side handle to be rotated 360° around said outer surface of said cap member. 13. The drill driver according to claim 10, wherein said torque adjustment collar is rotatable to control a torque setting of the drill driver. 14. The drill driver according to claim 10, wherein said cap member is secured to said gear case cover by screws. ow the cement retainer to cause the perforating assembly to discharge. 17. The method of claim 16, further comprising: removing the tubular string from the apparatus; placing a plug of cement on top of the cement retainer. 18. The method of claim 17, further comprising disposing a whipstock above the plug. 19. The method of claim 15, wherein the perforations are formed on an inner tubular and the cement is injected through the perforations and into an annular area between the inner tubular and an outer tubular. 20. The method of claim 15, further comprising setting a bridge plug in the wellbore prior to running the apparatus into the wellbore. 21. The method of claim 15, wherein setting the cement retainer comprises: rotating a setting tool connected to the cement retainer; and causing a radially expandable element around the cement retainer to expand. 22. An apparatus for use in plugging a wellbore, comprising: means for lowering a cement retainer and at least one radially expandable perforating assembly into the wellbore; means for setting the cement retainer against a casing; and means for discharging the perforating assembly. 23. The apparatus of claim 22, wherein the means for discharging the perforating assembly comprises at least one firing head. 24. The apparatus of claim 22, further comprising means for injecting cement through at least one perforation. 25. A method of plugging a wellbore, comprising: placing an apparatus on a tubular string, the apparatus comprising: a cement retainer; and a radially expandable perforating assembly disposed below the cement retainer; setting a standoff distance from the perforating assembly to a casing wall therearound; running the apparatus into the wellbore on the tubular string; setting the cement retainer to seal an annular area between the cement retainer and the casing wall; causing the perforating assembly to discharge, thereby forming perforations in the casing wall; and injecting cement through the tubular string and into a formation adjacent to the perforations. 26. An apparatus for use in plugging a wellbore, comprising: means for setting a parameter under which at least one radially expanded perforating assembly discharges within a wellbore; means for lowering a cement retainer and the perforating assembly into the wellbore; means for setting the cement retainer against a casing; and means for discharging the perforating assembly. 27. The apparatus of claim 26, further comprising means for setting the perforating assembly against the casing while lowering the cement retainer and the perforating assembly into the wellbore.
