The crankshaft is the most important part of an engine.
1. It takes the force from the connecting rod and converts it into torque through the crankshaft output and drives the other accessories on the engine to work.
The crankshaft is affected by centrifugal force of rotating mass, periodic gas inertia force and reciprocating inertia force, which makes the crankshaft bear the action of bending and torsional load.
2. Therefore, the crankshaft is required to have sufficient strength and stiffness, and the journal surface should be wear-resistant, uniform and balanced.
Several casting techniques are used in the crankshaft production process:
1.Smelting
Obtaining high temperature and low sulfur pure hot metal is the key to producing high quality ductile iron. Domestic production equipment is mainly based on cupola, and hot metal is not pre-desulfurization treatment; This is followed by less high purity pig iron and poor coke quality. Molten iron is melted in cupola, desulfurized outside the furnace, and then heated and adjusted in induction furnace.
2.moulding
The air impact molding process is obviously superior to the clay sand molding process, and can obtain high-precision crankshaft castings. The sand mold produced by this process has the characteristics of no rebound deformation, which is especially important for the multi-throw crankshaft.
3.Electroslag casting
Electroslag remelting technology is applied to the production of crankshaft, so that the performance of cast crankshaft may be comparable to that of forged crankshaft. And has the characteristics of fast development cycle, high metal utilization rate, simple equipment, superior product performance and so on.

Hi everyone,
This message comes to you from Matt Tessler. As of January 1, 2013, the Bensenville Fire Protection District updated their station numbering system. The fire station previously located at 500 S. York Road is now officially known as Station 17. This station now houses Battalion 17, Squad 17, Tower 17, Medic 17, Utility 17, Utility 18, and even a reserve engine for emergencies.
All the photos you see below were generously captured by Donald Tessler. He did an amazing job documenting everything. Let me walk you through each one:
1. **Battalion 17**: This is the main command vehicle for the station, ensuring quick coordination during emergencies.
2. **Squad 17**: A versatile rescue vehicle that helps with various types of rescues.
3. **Medic 17**: Equipped with advanced medical supplies, this vehicle provides on-site emergency care.
4. **Tower 17**: A critical piece of equipment for tackling high-rise fires or situations requiring aerial support.
5. **Utility 17**: Versatile and essential for maintenance tasks around the station.
6. **Utility 18**: Similar to Utility 17 but used for different operations.
7. **Medic 18**: Another ambulance-style vehicle, providing additional medical support when needed.
8. **Engine 18**: A firefighting workhorse designed to handle large-scale fires.
I’ve included some images below so you can get a better look at these impressive vehicles. Each photo gives a clear view of how well-maintained and professional-looking these vehicles are. It’s always great to see such dedication to safety and preparedness in our communities.
