Advantages of Crankshaft for BMW

 

A crankshaft is exactly what it sounds like. It’s a crankshaft designed to weigh less than a standard one. Manufacturers use special materials like billet aluminum, forged steel, or other composites. Some models are also machined to remove extra material. The goal is to reduce the rotating mass inside the engine. Less mass means the engine can rev faster and work more efficiently.

Types of Crankshaft for BMW
 

Fully built shaft

This type of crankshaft comes in individual parts. In other words, the crankpin, main journals, and crank web are apart. For this type, the individual crankshaft parts require assembling in a fully built shaft.

 

Welded shaft

These are crankshafts made by assembling the main journals on both sides of the crankpin and web. After assembly, the next thing is to use the submerged arc welding process to weld these components together.

 

Forged crankshaft

Often used in some 16-valve engines and high-stress ones, forged crankshafts are one of the strongest shafts. Made using a set of dies with a shape and size approximately that of the crank, this type of crankshaft is durable.

Solid single piece crankshaft

Made through either forging or casting, solid single-piece shafts have been used in both high-speed and low-speed engines. The crankshaft design makes it able to endure load incurred during cyclic tension and firing.

 

Billet crankshaft

Commonly made using steel, billet crankshafts are one of the best. Aside from steel, this crankshaft also contains other elements like molybdenum, aluminum, chromium, and nickel.

 

Cast crankshaft

Made with iron fabricated through the casting process, this type of crankshaft is present in various petrol and diesel engines.

 

Semi-built shaft

The first step in making this crankshaft is forging and shrink-fitting the crank webs to the general bearings. The next step involves providing the crankpins with a smooth surface finish through the machining process.

 

Application of Crankshaft for BMW

 

 

In BMW vehicles, the crankshaft plays a vital role in converting the reciprocating motion of the pistons into rotational motion, which is then used to power the wheels. It's a key component of the engine's internal combustion system.

 

Production Process of Crankshaft for BMW

The construction of crankshafts often relies on cast iron because of its excellent durability and ability to withstand the demand of engine operation. In certain cases, crankshafts are also manufactured using forged steel to withstand the heavy load involved.

 

Cast iron crankshafts are created through a casting process, while forged one involves heating a block of steel until it gets red hot. Subsequently, the forged steel is kept under high pressure to shape it in any desired form.

 

The manufacturing process of crankshafts also includes surface hardening and heat treatment techniques like carburising, nitriding etc., in order to enhance durability. Lastly, the choice of materials used for crankshaft construction depends on various factors such as operating conditions, the engine’s power output, and more.

FAQ

 

Q: What is a crankshaft on a BMW?

A: A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are driven by the pistons via the connecting rods.

Q: What happens when a crankshaft fails?

A: The results of these conditions can be a cracked or even broken crankshaft. You may hear a knocking noise from the engine, or notice that the engine's oil pressure is low (from a gauge or warning light). In severe cases, the engine will simply stop running.

Q: Is crankshaft serious?

A: A worn crankshaft often leads to a drop in oil pressure. This happens because the clearances between the crankshaft and bearings increase, causing oil to escape more easily. If the crankshaft sensor is damaged or malfunctioning, it can lead to engine misfires, as the engine's timing is thrown off.

Q: Does crankshaft affect performance?

A: Beyond simply making your car move, the crankshaft's design and balance are pivotal in the engine's overall performance. A well-balanced crankshaft ensures minimal vibrations, leading to smoother engine operation and better fuel efficiency.

Q: Can a car run with a bad crankshaft?

A: In modern cars, the position sensor provides useful information to the engine management systems, helping control and regulate the fuel injection, ignition timing, RPM, and more. Without a functional crankshaft sensor, your engine would not run properly.
