Claims
- 1. In a motor vehicle having an engine compartment with an air opening at one end thereof, an internal combustion engine having a plurality of aligned cylinders extending transversely across said engine compartment and driving a crankshaft rotatable in a crankcase about an axis extending transversely across said engine compartment, said cylinders extending upwardly from said crankshaft axis and being inclined from the vertical in a direction away from said engine compartment air opening, a dry sump lubrication system for said engine including a dry sump lubricant tank extending in the area between said cylinder and said engine compartment air opening and extending vertically upwardly from a point beneath said crankshaft axis to a point near the upper end of said cylinders to provide a substantial area exposed to the air flow through said engine compartment for cooling, and a lubricant pump having a driven shaft driven by said engine crankshaft and having a driven shaft axis disposed in a plane containing the axis of rotation of said crankshaft and angularly disposed at an acute angle to the vertical on the opposite side of the vertical from the cylinder axis, the angle between the cylinder axis and said plane being at an acute angle.
- 2. In a motor vehicle as set forth in claim 1 wherein the lubricant pump comprises a scavenge pump for drawing lubricant from the engine crankcase and returning it to the dry sump lubricant tank and a pressure pump for delivering lubricant from the lubricant tank to the engine for its lubrication.
- 3. In a motor vehicle as set forth in claim 1 further including means for driving an axle of the vehicle from the engine crankshaft.
- 4. In a motor vehicle as set forth in claim 3 wherein the vehicle axle axis is disposed on the opposite side of the cylinder axis than the pump axis.
- 5. In a motor vehicle as set forth in claim 4 wherein the lubricant pump comprises a scavenge pump for drawing lubricant from the engine crankcase and returning it to the dry sump lubricant tank and a pressure pump for delivering lubricant from the lubricant tank to the engine for its lubrication.
- 6. In a motor vehicle as set forth in claim 5 wherein the engine is positioned in a forwardly positioned engine compartment and drives the front wheels of the vehicle.
- 7. In a motor vehicle having an engine compartment with an air opening at one end thereof, an internal combustion engine having a plurality of aligned cylinders extending transversely across said engine compartment and driving a crankshaft rotatable in a crankcase about an axis extending transversely across said engine compartment, said cylinders extending upwardly from said crankshaft axis and being inclined from the vertical in a direction away from said engine compartment air opening, a dry sump lubrication system for said engine including a dry sump lubricant tank extending in the area between said cylinder and said engine compartment air opening and extending vertically upwardly from a point beneath said crankshaft axis to a point near the upper end of said cylinders to provide a substantial area exposed to the air flow through said engine compartment for cooling, and a primary transmission shaft driven by said engine crankshaft and having its rotational axis lying in a plane containing the crankshaft axis and at an acute angel to the vertical plane on the opposite side from the cylinder axis and lying at an acute angle to the cylinder axis.
- 8. In a motor vehicle as set forth in claim 7 further including a lubricant pump driven by the engine crankshaft and having a driven shaft rotatable about an axis coincident with the primary transmission shaft axis.
- 9. In a motor vehicle as set forth in claim 8 wherein the lubricant pump comprises a scavenge pump for drawing lubricant from the engine crankcase and returning it to the dry sump lubricant tank and a pressure pump for delivering lubricant from the lubricant tank to the engine for its lubrication.
- 10. In a motor vehicle as set forth in claim 9 wherein the engine is positioned in a forwardly positioned engine compartment and drives the front wheels of the vehicle.
