About Tappet and its Sourcing

Friday, September 26, 2008
In mechanical engineering, Tappet is referred to the projection of some kind which is imparting the linear motion to other component within an assembly. In other words, tappet is considered to that part of the rocker arm, which is in the contact of the intake or exhaust valve stem, placed above the cylinder head of the internal combustion engine. As the cam rotates it generates a sideways and downward force on the tappet. In the absence of any tappet, the sideways force would make the valve stem to bend. Due to the tappet, the sideways force gets transferred to the cylinder head which in turns make only the downward force acts on the valve stem. In case of the most modern overhead cam engines the camshaft comes directly over the valves. In the case of other overhead cam engines, a rocker arm pivots on a fixed shaft and the one projection of the rocker arm rides on a cam of the rotating camshaft. In both above mentioned cases, it gives rise to an oscillating linear motion, with the valve opening.

They are the U-shaped piece of metal which is secured with the help of pin or bolt across the opening or hinged metal loop secured with the help of a quick release locking pin mechanism.
Types of Shackles
a.) Pin Shackles- Such type of shackles are closed with the pin and is more commonly used in abroad boats.
b.) Threaded Shackles- As the name itself suggests, in threaded shackles, the pin is threaded with one leg of the shackle is tapped. The pin is 'captive' which prevents it from drooping loose.
c.) Snap Shackles- It is one of the fast action fastener which can be implemented single headed. It make use of spring activated locking mechanism for closing the hinged shackle and can be unfastened under the load.
d.) D-shackles- These are narrow shackles with a shape look like a loop of chain. It is one of the most common shackle as most of the other shackle types are its variation.
e.) Twist Shackles- Such shackles are somehow more longer than the average shackles with a 90 degree twist so the top of the loop becomes perpendicular to the pin.
f.) Bow Shackles- Looking like a larger 'O' shape to the loop, such shackle is able to take lots of loads from the different directions without bearing so much side load.

About Cylinder Block and its Sourcing

Thursday, September 11, 2008
The Cylinder Blocks are characterized as the machined casting which consist of the cylindrically bored holes for the pistons contained in the multi-cylinder reciprocating internal combustion engine. Cylinder blocks are considered as the complicated part in the center of the engine, having some adaption for attaching the cylinder head, engine mounts, crankcase with the way for passage of coolants and lubricants. These blocks are generally made up of the cast iron, aluminum or magnesium. Wet liner cylinder blocks consist of the removable cylinder bores, which get fitted into the blocks with the help of special gaskets and offer the benefits of being easily replaced without the emergence of any need of re-machining the whole casting. Wet line designs are more commonly used by the European manufacturers, especially by Renault and Peugeot, who are using it till now.

About Brake and its Sourcing

Wednesday, September 10, 2008
Brake is a device which is used to slow or stop the machine or vehicle motion. It is also used for retaining it from starting moving again. The kinetic energy which is lost by the moving part is generally get translated into heat by friction. Alternatively, in the regenerative braking, high amount of the energy is recovered, which get stored into the flywheel, capacitor and get turned into the alternating current by the alternator, then rectified and stored in the battery, to be used later. The friction brakes on cars have their heat storage in the rotating part while the brake application, which get released in the air gradually.
Brake and impact on Noise Pollution
The braking for motor vehicles produce sound level emission, which varies according to the tyre types and with the roadway surface type produces considerable effect upon sound levels or noise pollution emanating from moving vehicles. Due to the braking a considerable range in acoustical intensities get produced which depends upon the particular tire tread design and the speed of deceleration required to slow the vehicle.

About Piston Ring and its Sourcing

Tuesday, September 2, 2008
Piston Ring is known as the open-ended ring which, like an internal combustion engine or steam engine, gets fit into the groove on the piston outer diameter of a reciprocating engine. In the reciprocating engine, piston performs following 3 main functions-
  • It seals the combustion/expansion chamber.
  • It supports transfer of the heat from the piston to cylinder wall.
  • It regulates consumption of engine oil.
Automotive Piston Ring
Generally in most of the automobile pistons there are three rings. The top two besides controlling oil are primarily compression sealing. While the lower ring is used for controlling oil supply to the liner which in turns lubricate the piston skirt and the compression rings. One can find taper faced top rings also. Simple plain faced rings were used in the old engines.
Oil control rings are of mainly 3 types- Single piece cast iron, helicoil spring backed cast iron or steel, multipiece steel.

About Fly Wheel and its Sourcing

Saturday, August 30, 2008
A rotating disc, Fly Wheel is used for storing device for kinetic energy. Fly wheels resist any changes which occur in their rotational speed which in turns keep steady the rotation of the shaft at the time of exerting of fluctuating torque on it by its power source such as a piston-based (reciprocating) engine, or when the load placed on it is intermittent (such as a piston pump). These can be used for producing very high power pulses, required for doing some experiments where drawing the power from the public network would produce unacceptable spikes. Presently, fly wheels have become the subject of extensive research as power storage devices, to be used in vehicles.

Use of Fly Wheel

In recent times, a momentum wheel is used as the fly wheel type in satellite pointing operations, where it is used for pointing the satellite's instruments in the right direction without the thruster rockets. Fly wheels are also used in the punching machines and riveting machines for storing energy from the motor.

About Piston Valve and its Sourcing

Wednesday, August 27, 2008
Piston Valve is the device for controlling the fluid motion along with the tube or pipe with the help of the linear motion of the piston within the chamber or cylinder itself. It has the mechanical way of continuous adjustment of the upstroke and downstroke of various valves which in turns provide improved playing response. Piston valves are considered as one of the most powerful available in spudgunning having the ability to dump several litres of pressurised air in a few thousandths of second. Earlier piston valves were being used by Curtis Lo in his stationary steam engines and also in other engines after this. Cylindrical piston valves are used for changing the pitch during the playing of many brass instruments.
Examples of Piston Valve
  • Valve which is used in the valve gear of stationary steam engines and in various steam locomotives.
  • Valve which is used in the brass instruments.
  • Valve which is used in the pneumatic cannons.

About Spark Plugs and its Sourcing

Friday, August 22, 2008
Spark Plugs are known as the electrical device which gets fit into the cylinder head of the internal combustion engine and ignites compressed aerosl gasoline with the help of an electric spark. Earlier spark patents included those by Nikola Tesla, Richard Simms and Robert Bosch. Some historians have made a remark that the early spark plug was invented by the Edmond Berger on February 02, 1839. Karl Benz is also credited with the invention. But only the invention of the first commercially viable high-voltage spark plug as part of a magneto-based ignition system by Robert Bosch's engineer Gottlob Honold in 1902 made possible the development of the internal combustion engine.
Operation :
By the ignition coil or magneto, spark plug is connected at the high voltage. Due to the flowing of the electrons from the coil, a voltage difference gets developed between the center electrodes and side electrodes. No current can flow because the fuel and air in the gap is an insulator, but as the voltage rises further, it begins to change the structure of the gases between the electrodes. Once the voltage exceeds the dielectric strength of the gases, the gases become ionized. The ionized gas becomes a conductor and allow electrons to flow across the gap. Generally spark plugs need voltage in excess of 20,000 volts to fire properly. When the current of electrons surge across the gap, it increases the spark channel to 60,000k
Parts of the Spark Plug :
  • Terminal
  • Insulator
  • Ribs
  • Insulator Tip
  • Seals
  • Metal Case
  • Center Electrodes

About Disk Brakes and its Sourcing

Tuesday, August 19, 2008
The Disk Brakes are used for stopping the wheel rotation. A disk brake or disc brake is made up of cast iron or ceramic composites, including of carbon, kevlar and silica. It is connected to the wheel and/or the axle. For stopping the wheel , friction material in the form of brake pads is forced mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disk. Due to the friction, disk and attached wheel gets slow or stop.

History
Disk brakes were first used in england in 1890. Frederick William Lanchester in his Birmingham factory in 1902, patented the first ever automobile disk brakes, though it took another half century for his innovation to be widely adopted. In 1949, modern style disk brakes were first appeared on the low volume Crosley Hotshot. although they had to be discontinued in 1950 due to design problems. Chrysler's Imperial also offered another disk type brake from 1949 through 1953. In the UK entrusted modern disk brakes were developed by Dunlop and first appeared in 1953 on the Jaguar C-Type racing car.

Disks
The disks designs are changeable from place to place. Some disks are made up of simply solid cast iron and others are hollowed out with fins or vanes joining together the disk's two contact surfaces (usually included as part of a casting process). This "ventilated" disk design helps to dissipate the generated heat and is commonly used on the more-heavily-loaded front disks.

About Oil Filters and its Sourcing

Monday, August 18, 2008
Oil filter is used for decontaminating the oil with suspended impurities, Its major usage can be found in the forming part of the lubrication system of engines where filters are shown as the detachable units due to their need of regular service or replacement. For ensuring the longevity and high performance, filtration of oil in engines is necessary. Prior automobile industry did not use the oil filtration in any form. For this reason, along with the generally low standard of lubricating-oil refinement in the era, very frequent oil changes, of the order of every 500–1000 miles (800–1600 km) were often specified. Ernest Sweetland in 1923 discovered the original Purolator, the first modern oil filter.

Oil Filters Classification

a.) Mechanical - It has a filtration element which is made up of layers of media like paper for arresting various types of suspended contaminants. It requires the frequent replacement and cleaning.

b.) Magnetic - For capturing particles, dust these make use of permanent magnet or an electromagnetic. However with the help of this method one can filter only ferromagnetic contaminants. Its advantage is that for maintaining the filter one required only to wipe the magnetic clean.

c.)Sedimentation - Such filters allow heavier than oil contaminants to sink from the bottom of a conatainer under the influence of gravity.

d.) Centrifugal Oil Filters - Its opeartion process is simple as it uses the oil pressure from the main oil pump. Pressurized oil enters the center of the filter housing and passes into a "drum rotor". While maintaining this filter, engine must be switched off.

Uses of Oil Filters

The prime use of oil filter is in the reciprocating engine, which is mainly found n automobiles and light aircraft and various naval vessels. Such vehicles can have automatic transmission or demanding gearboxes that benefit from an oil filter. Turbine engines like those on the jet aircrafts require the use of oil filters. In various industrial applications like mining equipment, generators, metalworking machinery, oil filters are required.

About Gaskets and its Sourcing

Wednesday, August 13, 2008
A gasket is referred to the mechanical seal which is used for filling the space between two objects, more commonly for avoiding the leakages between 2 objects while under compression. It help in saving time by facilitating use of less precise matting surfaces to be used on the machine parts, which can used gaskets for avoiding any irregularities. More popularly, gaskets are produced by cutting it from sheet materials like rubber, silicone, metal, cork etc. For special usage it consists of the asbestos.

Gaskets can be used for various commercial and industrial purposes like aerospace and aeronautics, automotive, electronics, military and transportation industries. Some specific applications include: airframes, appliances, business machines, compressors, elevators, escalators, medical equipment, meters, turbines and valves.

Gaskets Classification on the basis of industrial designs

a.) Sheet Gaskets - These gaskets are used for meeting many chemical requirements based on the inertness of the material used and is price reasonable.

b.) Solid Metal Gaskets - These gaskets generally have a much higher level of quality control than sheet gaskets and generally can withstand much higher temperatures and pressures.

c.) Spiral Wound Gaskets - These gaskets utilizes a mix of metallic material and "filler material". Although expensive than sheet metal gaskets, these gaskets have proved their reliability in many industrial applications.

d.) Double Jacketed Gaskets - These are another combination of filler material and metallic materials.

About Valves and its Sourcing

Tuesday, August 12, 2008

Valve is a device used to regulate the flow of material, then it may be gas, fluidized solid, slurries, or liquid. Technically Valves are categorized under pipe fittings category, but due to its varied applications and different types they are discussed separately.

Generally valves are operated manually, either by a hand wheel or lever. Some valves are 'self-operating' driven by changes in pressure, temperature or flow. These changes in pressure or temperature often act against springs or capsules filled with expanding substances.


One can think about the vast nature of valves just by seeing the fact that valves are available in a size of 6 mm to 5000 mm diameter.

Valves Classification on the basis of operating positions

a). 2-Way Valves - - Also known as 2-port valves. Operating positions for such valves can be either shut (closed) so that no flow at all goes through, fully open for maximum flow, or sometimes partially open to any degree in between

b). 3-Way Valves - - Also known as 3-port valves. Three-way valves are commonly made such that flow coming in at one port can be directed to either the second port in one position or the third port in another position or in an intermediate position so all flow is stopped. Often such 3-way valves are ball or rotor valves.
