The function of a Crank Casing

A crank casing is the housing for the crankshaft in a reciprocating internal combustion engine. The crank casing seals the bottom of the cylinders and contains the oil pan. The oil pan drains and stores oil that lubricates the engine bearings. The oil is pumped through passageways in the engine block and crank casing to lubricate the cylinder walls, connecting rods, and crankshaft bearings. Excess oil is then returned to the pan.

The crankcase also houses the timing gears or chain and the balance shafts, if used. The main bearings support the crankshaft in the crankcase. The connecting rods connect the pistons to the crankshaft. The pistons are sealed at the top by the piston rings and at the bottom by the piston wrist pin. The piston pin connects the piston to the connecting rod.

The crankcase ventilation system removes blow-by gases from the engine. The blow-by gases are created when the piston rings do not seal perfectly and some of the combustion gases escape past the rings into the crank casing. These gases are vented to the atmosphere or routed back into the engine intake to be burned.

The different types of crank casing materials

Car engines are usually made from aluminium alloy. However, there are some that are made from cast iron. There are advantages and disadvantages to both materials.

Aluminium is much lighter than cast iron, so it helps to keep the weight of the engine down. It is also a good conductor of heat, so it helps to keep the engine cool. However, aluminium is not as strong as cast iron and it can be more difficult to work with.

Cast iron is much heavier than aluminium, but it is very strong. It is also a good conductor of heat, so it helps to keep the engine cool. However, cast iron is difficult to work with and it can rust if it is not properly protected.

The advantages and disadvantages of each type of crankcase material

The three main types of crankcase materials are cast iron, aluminum, and magnesium. Each has its own advantages and disadvantages that must be considered when choosing the right material for an application.

Cast iron is the most common material used for crankcases. It is strong and durable, making it ideal for high-performance applications. However, cast iron is also very heavy, which can negatively affect fuel economy.

Aluminum is much lighter than cast iron, making it a popular choice for racing applications. It is also more resistant to heat, which can be an issue with cast iron crankcases. However, aluminum is not as strong as cast iron and is more susceptible to damage.

Magnesium is the lightest of the three materials and is often used in applications where weight is a major concern. It is also very resistant to heat, making it a good choice for high-performance applications. However, magnesium is not as strong as either cast iron or aluminum and can be more susceptible to damage.

The importance of proper crankcase maintenance

The crank casing is the lower part of an engine, where the crankshaft is housed. The crankcase plays an important role in keeping the engine lubricated and cool, and also helps to reduce noise and vibration.

It is important to maintain the crank casing in good condition, as this can help to prolong the life of the engine. There are a few simple things that you can do to keep your crank casing in good condition:

– Check the oil level regularly and top up if necessary.

– Change the oil and filter according to the manufacturer’s recommendations.

– Keep the crank casing clean and free of debris.

– Inspect the crankcase for signs of leaks or damage.

If you take good care of your crank casing, it will help to keep your engine running smoothly for many years to come.

5. Tips for prolonging the life of your crankcase

Your crankcase is one of the most important parts of your engine, and it’s important to keep it in good condition. Here are five tips to help prolong the life of your crankcase:

  • Keep your crank casing clean.

This might seem like an obvious tip, but it’s important to keep your crankcase clean if you want it to last. Make sure to regularly clean the outside of the case and remove any dirt or debris that could potentially cause damage.

  • Change your oil regularly.

One of the best ways to prolong the life of your crankcase is to change your oil regularly. Dirty oil can cause all sorts of problems, so it’s important to keep it clean. Most experts recommend changing your oil every 5,000 miles or so.

  • Inspect your crankcase regularly.

It’s a good idea to inspect your crankcase regularly for any signs of wear or damage. If you notice any cracks or other damage, it’s important to get it fixed as soon as possible.

  • Use the proper lubricants.

Using the proper lubricants is important for prolonging the life of your crankcase. Make sure to use the right oil and avoid using any other fluids that could potentially damage the case.

  • Store your crankcase properly.

If you’re not using your engine, it’s important to store your crankcase properly. Make sure to clean it before storing it and keep it in a cool, dry place.
