Abstract
An engine line is described herein that includes a first engine including a front end accessory drive system and a second engine including a greater number of cylinders than the first engine and a front end accessory drive system. The engine line further includes a generator, in different manufacturing arrangements, mounting to each of the front engine accessory drive systems in the first and second engines in a common location.
Claims20
A direct-injection internal combustion engine comprising:
- a cylinder head having at least three cylinders in an in-line arrangement along a longitudinal axis of the cylinder head;
- where each cylinder has an inlet opening for the supply of combustion air into the cylinder via an intake system, each inlet opening being adjoined by an intake line, and the intake lines of the cylinders merging to form an overall intake line, thus forming an intake manifold;
- where each cylinder has an outlet opening for discharging the exhaust gases via an exhaust-gas discharge system, each outlet opening being adjoined by an exhaust-gas line;
- where each inlet opening is equipped with an inlet valve, and each outlet opening is equipped with an outlet valve;
- where each cylinder comprises a piston articulatedly connected to a crankshaft;
- where the piston oscillates along a cylinder longitudinal axis as the crankshaft rotates about an axis of rotation, the cylinder longitudinal axis being perpendicular to the axis of rotation of the crankshaft;
- where each cylinder is equipped with an injection nozzle for the direct introduction of fuel into the cylinder;
- and
- where the cylinder-specific injection nozzle is arranged centrally, without a spacing to the cylinder longitudinal axis, and is oriented along the cylinder longitudinal axis;
- where the intake lines combine at a merged intake line section within the cylinder head;
- where the merged intake line section is arranged closer to a first outer cylinder than a second outer cylinder;
- and
- where the first and second outer cylinders are included in the at least three cylinders.
