  • What is the value of the turbocharger?
  • What is it made of?
  • How does it work?
  • Where can it applied?
  • Likely problem encountered


Ignorantly we think the main reason motor A generates more power,higher velocity,consumes less fuel, sometimes environmental friendly than motor B is because of the engine structure or size. But there is one way to improve an engine which is the turbocharger.

 The turbocharger is an exhaust-gas driven component of an engine that increases the volumetric efficiency of air in an engine in order to increase its power.  It consist of a casing,impellers and shaft.

 Generally, the charge[mixture of fuel and air] that flows into the combustion chamber produces the torque that turns the engine. For the engine to produce or generate more power there are two alternatives, firstly, is to increase the size of the engine[the cylinder block,cylinder wall,pistons] so that the total volume of intake increases. The second option is to generate air externally.

 Several medium can aid the supply/generating of air into the engine, of which, are the supercharging,turbocharging and others.The turbocharger is of advantage over the supercharger because it uses the exhaust gas of the engine to power the impellers thereby generating the air needed whereas the supercharger uses the crankshaft of the engine connected via belts to power it blades.

 Some might ask, of what importance is the turbocharger aside increasing the torque that turns an  engine, ok, here it is
  • It reduces the stress of an engine by decarbonizing
  • It cleans the combustion chambers
  • It adds 20hp to the engine
  • The turbo charger acts like a silencer
  • It reduces the stress of the valve
  • It increases the power of the engine with less fuel

WHAT IS IT MADE OF?

The turbocharger consists of a compressor and a turbine. The compressor and the turbine consist of impellers and are connected via a shaft.

The impeller in the turbine is responsible for the discharging of pressure in the engine and also sucks out the exhaust gas while the impeller of the compressor receives the exhaust gas. The compressor and turbine of the turbocharger are connected via a shaft which controls and enable smooth rotation.


HOW DOES IT OPERATE? 

It operates with a simple principle. It uses the exhaust gas to drive the turbine which spins the compressor hence pushes extra air[oxygen,densed] into the cylinders,allowing them to burn more fuel each second.

The turbine and the compressor consist of impeller which are connected via a shaft that enables them spin alongside.
The turbine is connected to the exhaust manifold. When hot gases passes through the impellers of the turbine they rotate as well as the shaft hence causing the impellers of the compressor to rotate. As the impellers in the compressor of the turbocharger which is connected to the intake manifold rotates, it draws air into the engine and forces it into the cylinder through an heat exchanger.
Note:the heat exchanger is used to make the air cooled and denser.



WHERE CAN IT BE APPLIED

It can be installed in the otto cycle engines and Diesel cycle engines



LIKELY PROBLEM ENCOUNTERED

  • Grinding of shaft
  • seizing of shaft from rotating. This can lead to overheating of the turbocharger itself.

THE FUNDAMENTALS OF THE TWO STROKE CYCLE ENGINE

-
Image
There are uncertainty about the longevity of the two stroke cycle engine as compared to other cycle of operation .Knowledge of Its importance and principles of operation will help justify the strength of the two stroke cycle engine as compared to others.  Internal combustion engine dated back to 1876 when Dr. Nicolaus A. Otto first invented the spark ignition engine[petrol], then Rudolf Christain Karl Diesel developed the compression ignition engine[Diesel]. Since then engines have continue to develop with new technologies as well as increase in the knowledge of engine process. The purpose of the internal combustion engine is the production of mechanical power from chemical energy contained in fuel. The energy is released by burning the fuel inside the engine.  According to the cycle of operation,engines are classified as the two stroke cycle,four stroke cycle six stroke cycle and the rotary combustion. The rise in global technology which increased the demand of new type of engi

Image
Fortunately you discovered you just pumped petrol instead of diesel into your compression ignition engine(Diesel engine). Oh my! the knowledge they burn completely different(volatile versus high flash point) must give you a lot to worry about. Don't panic too much, there's are ways to get over it. Filling a fuel tank is a simple task, but seconds of carelessness might result to some expensive nuisance. Possibly you might be a newbie to compression ignition engine(C.I engines) or maybe a veteran in the use of it or Probably you might be familiar to the C.I engine and the spark ignition engine,Good one. Herein this article, the anti and post caution will be highlighted. Petrol and Diesel in the fuel tank Early discovery of this nuisance will help reduce the cost of repair,that is towing immediately to he mechanical workshop for the petrol to be completely drained.  The worst case might be when the engine starts running with the fuel tank full of petrol--there are chance

THE BASICS OF THE COMPRESSION IGNITION ENGINE

-
Image
The compression ignition engine[C.I engines] also known as the diesel engine is invented by Dr. Rodolph Diesel. The C.I engine is an internal combustion engine in which combustion occurs as a result of the compression of the air to a temperature sufficient enough to ignite the fuel. There are several similarities and minor difference between the C.I engines and the gasoline powered engines(spark ignition engines,S.I engines). The components such as the crankshaft, camshaft, piston,valves etc they both share in common.  The same cycle of operation governs both for the four stroke and two stroke engine process. However the diesel engines can easily be recognized by the absence of the ignition system and other factors such as Injection of fuel is done via an injection pump They are noisy and produces pollutants easily It produces more power and torque Overtime, diesel engines have received massive success in the construction of heavy duty trucks,construction equipment ,power pl

THE MAIN FACTORS BEHIND LOSS OF POWER IN AN ENGINE

-
Image
Most operators lacks the proper knowledge on how to use and maintain an engine. Knowing the requirements for an engine to produce power and other function are important factors that must be learned in engine maintenance.   Humans are mostly ignorant of the sign of power loss that emanate from the engine even when they are sometimes pronounced. For an engine to produce or loss power there are four factors that must be consider AIR FUEL COMPRESSION SPARK PLUG AIR Generally, in the absent of air, combustion of fuel can not occur. The mixture of air and fuel, known as the charge is a major factor for an engine to produce power,in absential power can not be generated. Air contains dust,dirt particles and other contaminants of which if drawn into the injector, it causes blockage of  the injector nozzle and the running jet of the carburetor. in cases like this, the air filter is applied to prevent the dirt and contaminant from flowing through to the mixing chamber. The air

The 21st century scientists are working extremely hard to make life easier for humans.  The invention of domestic and industrial robots and other devices makes the work done efficient,  though it threatens welfare of humans. Scientists have developed robotic fish to help researchers do underwater research. The robo-fish can swim alongside real fish to give new perception into life below. The robotic fish named SoFi was developed by MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), can be controlled with sound. SoFi swims by flapping its hydraulic-pump powered tail back and forth.  The clever robot can also control its own buoyancy through adjusting an internal foam material. During test dives in the Rainbow Reef in Fiji, SoFi was able to swim down 15 meters for more than 0 minutes at a time. It could navigate and respond to current and avoid collision with coral. During the swim, SoFi collected data by taking photos and videos using its b

1. The Carthedral: A Cathedral on Wheels Built from a hearse and topped with a VW Bug, Rebecca Caldwell's Carthedral is an ambitious gothic car art piece. The piece is entirely street legal, and features spires, buttresses, and other gothic flourishes you'd expect to find in a several-centuries-old church. 2. The Phantom Built by Truant Studios' William T. Burge,  The Phantom  began with only a VW motor, an axle, suspension and steering. Burge built the entire body from scratch, welding small pieces of steel together to create the car's iconic look. It features three imposing gargoyle heads, and its design is based on that of a 1936 Bugatti Atlantic. 3. Thor: The Norse God of Cars Built in Denver, Colorado, the  Thor art car  started as a Burning Man mutant vehicle project. Since its debut at the festival, it has traveled the world.
