Deep rolling is a method of cold work deformation and burnishing of internal combustion engine crankshaft Journal mechanics journal Fillet mechanics fillet s to increase durability and design safety factor s. Compressive residual stress es can be measured below the surface of a deep rolled fillet. Other types of fillets on shafts or tubes can also benefit from this method. Cast iron crankshafts will experience the most improvement potentially doubling their fatigue life. Typically the crankshaft is machined with undercut manufacturing under cut fillets as opposed to tangential radiused for ease of manufacture, although all types can be deep rolled. Most automakers are currently utilizing this technology including GM, Ford, and Chrysler engines. Hegenscheidt MFD Corporation, the French SPMS SUPRAMATIC brand, and ICM teamed with Lonero Tooling are the only major machine tooling manufacturers of this application in Europe and North America, supplying a highly specialised product throughout the global manufacturing sectors.

The Crankshaft position sensor also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the ECU to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. Typically a Hall Effect sensor is used as the static part requiring a magnet to be mounted somewhere in the periphery of the rotating disc, but other detection principles can also be employed i.e. optical sensor optical or inductive sensor inductive . Purpose The functional objective for the crankshaft position sensor is to determine the position and rotational speed RPM of the crank. Engine management systems use the information transmitted by the sensor to control things such as ignition timing and fuel injection timing. The sensor output can also be related to other sensor data including the cam position to derive the current combustion cycle. While there are several competing objectives in the fuel injection system it was primarily designed for controlling and improving power output fuel efficiency exhaust gas emission s performance ability to accommodate alternative fuel s reliability driveability and smooth operation initial cost maintenance cost diagnostic capability range of environmental operation Physical location The rotating disc of the sensor system does not necessarily have to be mounted directly on the crankshaft but can also be driven by a chain or toothed belt off the crankshaft as is the case in some Honda s where the crank position sensor is located in the distributor, effectively driven by the timing belt. Other locations include The front of the crank on the engine block below or next to the water pump, on the main crank pulley or near the flywheel. Problems encountered Sometimes the sensor may become burnt or worn out. The most likely causes of crankshaft position sensor failure are exposure to extreme ... more details

Context date October 2009 6 bolt main refers to the number of bolts holding the main caps to the engine block, and therefore holding the crankshaft in place. A main cap refers to the locating support for the crankshaft of a piston engine. The main cap holds the crankshaft in the engine with fasteners of two, four, or six bolts. The common logic is, the more bolts, the better. In general, 6 bolt main designs are considered the strongest under all conditions. In most cases the mains are held in by four bolts from the bottom extending upward into the block, two on each side of the crankshaft, and two Cross bolted bearing cross bolts coming from the left and right side pan rails into the side of the main caps to provide additional lateral support at excessive engine speeds. Ford modular engines with superchargers, or dual overhead cam heads come with this design. ref http www.seanhylandmotorsport.com ref See also 4 Bolt Mains Main bearing References reflist DEFAULTSORT 6 Bolt Main Category Engine components automotive tech stub ... more details

A harmonic damper is a device fitted the free accessory drive end of the crankshaft of an internal combustion engine . It is essential in engines with long crankshafts such as straight 8 engines and is present on most engines as it reduces torsional vibrations that tend to peak at certain speeds. Need Without the presence of a damper a long crankshaft will tend to act as a torsional spring to some extent. Impulses applied to the crankshaft by the connecting rod s will tend to wind this spring, which will respond as a spring mass system by unwinding and re winding in the opposite direction. This will usually be damped out naturally, but at certain crankshaft rotational speeds the impulses from the cylinder firing can be in synchronization with the natural resonant frequency. Some aircraft engines are restricted from continuous operations at specific RPM to avoid the danger of metal fatigue causing a break in the crankshaft. In an automotive engine there is little control over operation in such specific speed bands and furthermore there may be uncomfortable vibrations as the engine is operated through such speeds, even if not a problem for engine durability. Many small block V8 engines, such as Ford Windsor and Cleveland, Chevrolet small block 400 and big block 454, and certain Crysler V8s, a portion of the crankshaft system s overall balancing may be provided by an unbalanced damper. Construction The damper consists of an inner hub affixed usually by a key and keyway to the outer end of the crankshaft. An outer circular mass is attached to the hub by an integral rubber or other elastomeric section. This crankshaft and damper together become in its torsional response a spring mass damper system. By selection of the damping section material and the size of the outer mass the damper may be made to resist and thus quiet the specific torsional vibrations. These vibrations will not be at the same frequency as originally since additional mass has been added to the resonant system ... more details
The crossplane or cross plane is a crankshaft design for V8 engines with a 90 angle between the cylinder banks. File Crossplane.png thumb right 3d model of a cross plane crankshaft demonstrating the 90 degree angle between the crank throws and the large counter weights. The crossplane crankshaft has four crankpin s, each offset at 90 from the adjacent crankpins. The first and last of the four crank pins are at 180 with respect to each other as are the second and third, with each pair at 90 to the other, so that viewed from the end the crankshaft forms a cross. The crankpins are therefore in two planes crossed at 90 , hence the name crossplane . A crossplane crank may have up to five main bearing s, and normally does, as well as large balancing weights. Crossplane V8 engines have uneven firing order firing patterns within each cylinder engine cylinder bank, producing a distinctive burble in the exhaust system exhaust note, but an even firing pattern overall. Their second order balance means no additional balance shaft is necessary to achieve great smoothness. The other design for a V8 crankshaft is the flatplane crankshaft, with all crankpins in the same plane and the only offset 180 . Early V8 engines, modern racing engines and some others used or use the flatplane crankshaft, which is similar to that used in a straight 4 straight four or flat four engine. Flatplane V8 engines may use any angle between the cylinder banks, with 60 and 90 the most common. They lack the V8 burble and the superior engine balance mechanical balance of the crossplane design, but do not require the large crankshaft balancing weights. Inherent balance of the big ends is like a straight four, and modern designs often incorporate a balance shaft for smoothness. But without balance shafts, flatplane ... crankshaft and utilises a specially designed balancer to counteract the unusual vibration found in this type ... power delivery.

Roller burnishing is a method of cold working metal surfaces to induce compressive residual stress es and enhance surface roughness qualities. The tooling typically consists of a hardened sphere or cylindrical roller. These tools are pressed onto across the part being processed. The part or the tool in some applications must be moving at a constant rate of speed, for example in the case of roller burnishing a part on a lathe, the part is spinning and the burnishing tool is moved across the surface as a constant rate therefore, producing a very consistent finish across the part. Another application is thrust bearing surfaces of some production crankshafts. A dual roller cylindrical tool is moved into the thrust bearing journal of a crankshaft, while the crankshaft is spinning the tool is indexed so each roller is perpendicular to the thrust surface while backing each other up deforming the surfaces. So the diameters of each roller added together compensated for elastic deformation equals the finish dimension of the thrust bearing.

A table engine is a variety of stationary steam engine where the cylinder is placed on top of a table shaped base, the legs of which stand on the baseplate which locates the crankshaft bearings. The piston rod protrudes from the top of the cylinder and has fixed to it a cross head which runs in slides attached to, and rising from, the cylinder top. Long rods connect the crosshead to the crankshaft, on which is fixed the flywheel. This pattern engine was first introduced by James Sadler in the Portsmouth Block Mills and was house built in that its framing was fixed to the engine house. Henry Maudslay patented an improved version of this a few years later, and other makers adopted the configuration. It was supplied for low speed, low power applications around the first half of the nineteenth century.

orphan date April 2010 Unref date June 2009 Mallory metal is an alloy of tungsten , with other metallic elements added to improve machining. Its primary use is as a balance weight which is added to the crankshaft of an automotive engine, where the existing counterweight is not large enough to compensate for the weight of the reciprocating and rotating components attached to the crankshaft s connecting rod journals. Rather than add to the counterweight by welding or fabrication, holes are drilled in structurally safe positions in the counterweights, and slugs cylindrical dowels of Mallory metal are inserted and fastened securely. The difference in density between the replacement Mallory metal and the original steel is about 2 1, so the counterweight is heavier without changing its shape or size.

Unreferenced date November 2006 A crank sensor is a component used in an internal combustion engine to monitor the position or rotational speed of the crankshaft . This information is used by engine management system s to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine. The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the piston s and Tappet valves in the engine, which is particularly important in engines with variable valve timing . It is also commonly the primary source for the measurement of engine speed in revolutions per minute . Crank sensors in engines usually consist of magnets and an inductive coil, or they may be based on magnetically triggered Hall effect semiconductor devices. Common mounting locations include the main crank pulley , the flywheel , and occasionally on the crankshaft itself. This sensor is the most important sensor in modern day engines. When it fails, there is a small chance the engine will start engine will likely cut out after a few minutes of driving but it mostly will not start. Citation needed date September 2009 Some engines, such as GM Premium V engine GM s Premium V family , use crank position sensors which read a reluctor ring integral to the harmonic balancer . This is a much more accurate method of determining the position of the crankshaft, and allows the computer to determine within a few degrees the exact position of the crankshaft and thereby all connected components at any given time. Another type of crank sensor is used on bicycle s to monitor the position of the crankset , usually for the Cadence cycling cadence readout of a cyclocomputer .
