A vehicle includes a vehicle structure that extends along a longitudinal axis. An engine includes a crankshaft that defines a crank axis disposed substantially transverse to the longitudinal axis. A transmission includes an output shaft that defines a transmission output axis substantially parallel with the crank axis. The transmission output axis is disposed nearer the forward end of the vehicle structure than the crank axis. The crank axis is disposed vertically above the transmission output axis a distance of about 140 mm. The engine includes at least one cylinder bore that defines a bore axis disposed perpendicular to and may intersect the crank axis. The bore axis may be angled toward the forward end of the vehicle structure to define an angle between the bore axis and a vertical plane. The angle between the bore axis and the vertical plane may be about 18&#xb0;.

Integrated powertrain and chassis design for maximized passenger cabin volume of a vehicle

A vehicle includes an engine assembly configured to power a vehicle. The engine assembly defines a first engine end and a second engine end opposite the first engine end. The first engine end is spaced apart from the second engine end along a first direction. The engine assembly defines a third engine end and a fourth engine end opposite the third engine end. The third engine end is spaced apart from the fourth engine end along a second direction. The second direction is substantially perpendicular to the first direction. The vehicle further includes a steering assembly disposed in close proximity to the engine assembly. The steering assembly includes a steering body disposed closer to the first engine end than to the second engine end.

Powertrain and steering assembly layout

A motor vehicle has an internal combustion engine mounted in a central tunnel of the vehicle floor pan. The internal combustion engine comprises an engine block assembly having a lower end closed by an oil pan and an upper end extending at an angle &#x3b1; from a rear of the engine block assembly to a front thereof. An engine block closes the upper end and defines a crankcase that is configured to house a crankshaft for rotation therein. A cylinder housing assembly is reclined from vertical, towards the rear of the engine block, about an axis of the crankshaft by an angle &#x3b2;. At least a portion of the cylinder housing assembly and the crankcase are disposed in the central tunnel of the vehicle floor pan.

Internal combustion engine and vehicle packaging for same

An exhaust system for an engine comprises a cylinder head having an integral exhaust manifold to collect exhaust gas exiting the engine combustion chambers. An exhaust gas conduit in fluid communication with the exhaust manifold comprises an inlet end connected to the cylinder head, a portion that extends towards an upper end of the internal combustion engine and an outlet end configured to define an inlet end of a multistage catalytic converter. The catalytic converter comprises a canister having an inlet end located adjacent the top of the engine and includes first and second catalyst substrates and a collector closing an outlet end of the canister. The outlet end of the canister is located adjacent to the bottom of the engine, and the first and the second catalyst substrates receive and convert constituents of exhaust gas passing from the inlet end of the canister to the outlet end.
