A hybrid engine 10 for propelling a vehicle comprises a balanced, preferably twin cylinder, flat internal combustion engine 11 whose crankshaft 19 is coupled to a generator 12 that has rotating permanent magnets 35. The internal combustion engine 11 comprises a first and a second piston 13, 14 drivingly connected to the crankshaft 19 via a first and a second connecting rod 16, 18 respectively. The first piston 13 and the second piston 14 are disposed on opposite sides of the crankshaft 19 so that the longitudinal axis of the pistons 13, 14 are aligned, i.e. they are coaxial, to reduce out of balance forces. One of the connecting rods 16 may comprises a first and a second limb 16a, 16b connected to the crankshaft 19 by a first and a second big end bearing 20a, 20b respectively while the second connecting rod 18 may be connected to the crankshaft 19 by a third big end bearing disposed between the first and second bearings 20a, 20b. |
