Automotive Superchargers – Their Care & Maintenance
Posted by admin in Automotive on July 14, 2011
Turbochargers are superchargers that are driven by the force of the automobile engine exhaust. It can be confusing listening to fast car buffs and car guys as often turbochargers are referred to simply as “turbo-superchargers”. These fast car, high speed race car auto speed devices literally ram the air into the vehicle’s engine by raising the pressure of the air in the motor’s intake manifold.
Although turbochargers can spin at great speed, unbelievably up in the ranges of 10,000 revolutions per minute (rpm), surprising they are relatively trouble free over their lifetimes and overall can be counted on the provide great boosts of speed reliably with little complaint and need little routine service or care.. Sure though gaskets must remain in good and sealed order. Fasteners proper torque and the oil supply to the unit open and functioning clean and well. As well auxiliary controls such as boost control must operate correctly.
If service has to be done generally the professional mechanic will find that when they remove the unit from the engine, if is essential to clean before removal and as well cover any openings that lead into the engine itself. It is more than essential that extreme care should be practiced and maintained during handling and repair to avoid the slightest nicking or bending of any part of the turbine or compressor blades. Blade damage can and will seriously reduce the unit’s lifespan and life time. In some extreme cases it can even cause the unit to spin out of control and high speeds, fragmenting and basically destroying itself in the process. Read the rest of this entry »
Automotive Radiator
Posted by admin in Automotive, Radiator on July 14, 2011
Ever since cars began appearing on our roads over a century ago, heat dissipation has been a crucial problem that all automobile manufacturers have tried to tackle. An automobile engine produces enough heat to burn itself out. Unless this heat finds a proper outlet, the engine will be severely damaged.
Automotive radiators have been instrumental in keeping the heat produced under control. These relatively simple devices have a complex function to perform under the hood of the car. In simple terms, a radiator is a device that dissipates heat through radiation. All automotive radiators, whether in cars, trucks, buses and tractors, use the same principle while functioning. The liquid coolant that passes through the engine absorbs all the heat produced, keeping the engine temperature under control. However, this coolant needs to be cooled off in order to repetitively perform the same function. That is where the radiator comes into the picture. An automotive radiator is made of an aluminum tube, bent several times to form a rectangle. These multiple folds increase the internal surface area of the radiator and hence enhance the cooling. As the coolant passes through the radiator, the heat is absorbed by the aluminum body and dissipated into the cool air blowing surrounding it. Very often, an electric fan blows cold air into the radiator to expedite the cooling process.
Automotive radiators have evolved in design and efficiency over the years. The first radiators were a simple network of round brass or copper tubes with water flowing through them. Later, fans were added to the kit to enhance the cooling effect. Read the rest of this entry »
