Abstract
A structural frame is provided. The structural frame includes a bottom surface, first and second cylinder block sidewall engaging surfaces, the first and second cylinder block sidewall engaging surfaces positioned above the bottom surface at a height that is above a centerline of a crankshaft support included in a cylinder block when the structural frame is coupled to the cylinder block.
Claims20
An engine, comprising:
- a structural frame including a bottom surface, and first and second cylinder block sidewall engaging surfaces;
- and
- a cylinder block including a cylinder, at least two crankshaft supports at a bottom of the cylinder block, a cylinder head engaging surface at a top of the cylinder block, and first and second exterior sidewalls, the first exterior sidewall extending from the cylinder head engaging surface to the first cylinder block sidewall engaging surface positioned above a centerline of a crankshaft supported by the at least two crankshaft supports, the first and second cylinder block sidewall engaging surfaces positioned above the bottom surface and above the centerline.
An engine, comprising:
- a cylinder block having two or more cylinders arranged in a non-straight angle, two crankshaft supports at a bottom of the cylinder block, first and second cylinder head engaging surfaces at a top of the cylinder block, first and second exterior sidewalls, the first exterior sidewall extending from the first cylinder head engaging surface to a first structural frame engaging surface positioned above a centerline of a crankshaft supported by the two crankshaft supports, the second exterior sidewall extending from the second cylinder head engaging surface to a second structural frame engaging surface positioned above the centerline of the crankshaft, a transmission bell housing engaging surface at a rear of the cylinder block, the first and second structural frame engaging surfaces each including a plurality of fastener openings;
- and
- a structural frame including first and second structural frame exterior sidewalls, the first structural frame exterior sidewall coupled to the first cylinder block exterior sidewall, the second structural frame exterior sidewall coupled to the second cylinder block exterior sidewall, the first structural frame exterior sidewall and the second structural frame exterior sidewall coupled via a transmission bell housing engaging surface at a rear of the structural frame.
A cylinder block assembly comprising:
- a cylinder block having a crankshaft opening with a centerline;
- a structural frame coupled to the cylinder block;
- the frame including:
- an oil pan engaging surface, first and second cylinder block sidewall engaging surfaces, the first and second cylinder block sidewall engaging surfaces positioned above the oil pan engaging surface at a height that is above the centerline, and an oil pan coupled to the frame.
