What A Turbocharger Does?

A turbocharger can be defined as forced-induction system which enables an engine to come up with enhanced power production, irrespective of any engine size. The turbocharged engines could be more efficient and powerful than naturally aspirated ones since turbine pushes in more air & more fuel inside combustion chamber, apart from atmospheric pressure. The turbochargers are generally used on car, truck, aircraft, train & construction-equipment engines. These are a vital accessory for vehicles and can enhance the engine prowess by 35 percent. The post here is a brief describing what does a turbocharger do.


Turbochargers help to improve the engine horsepower. Generally, a solo turbocharger is appropriate for the diesel engines & 2 turbochargers are preferred for the gasoline engines. The turbochargers are designed to enhance the volume of air intake necessary by a vehicle engine for improved fuel combustion. The turbocharger is made up of two types of impeller which are separated by one chamber.  When the exhaust part releases air, one of the turbo impellers will start to rotate & since the impellers are joined together, another one connected directly to intake manifold will turn itself thereby adding air in combustion process.

The turbo compressor pulls in the ambient air & compresses it prior to letting it enter into intake part at enhanced pressure. It results in greater air mass entering cylinders on every intake stroke. Power required to spin on centrifugal compressor comes from kinetic energy derived from engine’s exhaust.

Turbochargers are also utilized to improve fuel efficiency of a vehicle, without improving power. It’s accomplished by recovering exhaust waste energy & feeding that back into engine intake. As turbocharger uses the otherwise wasted-energy for increasing air mass, it gets smoother to assure that all the fuel gets burnt prior to getting vented out at the beginning of exhaust stage. Enhanced temperature from higher pressure offers higher efficiency for the vehicle engine.

You should be very careful regarding the maintenance of turbocharger since it determines your engine performance. According to turbocharger experts, clean engine fluid is primary in ensuring good health for turbochargers.

How Do A VTEC Engine Works

VTEC Engine is one of the most sought after advancements in the contemporary automotive scene. The cutting edge engine feature has been introduced by esteemed automobile giant Honda Motor Company. The post below is a short brief on the functioning aspects of VTEC engine.

Before proceeding with the VTEC engine, you must know a bit about engine camshafts. Camshafts are vital for running engines at correct speeds and ranges. Cars equipped with lower rpm camshaft would function best while their engines are running at lower rotational rate. Gain, some of the cars have camshafts designed to close & open valves in swift succession while running at higher rpm.  A vehicle needs a completely different camshaft portfolio to perform effectively at both low and high speeds.


However, Honda has already figured out the way for a car engine to stay armed with multi camshafts so that the engine can switch these out effectively when needed. The system has been introduced as VTEC- Variable Valve Timing & Lift Electronic Control. VTEC involves a simple concept. Its mission is to permit the engine to function with optimum efficiency all through the whole RPM range, sans any sort of weakness at any definite range or spot.

VTEC camshaft comprises of one larger lobe centered in between 2 main smaller lobes. The very point when VTEC lobes start to function on engine, is usually termed as “the VTEC crossover”. As VTEC kicks in, one little hydraulic pin would be forced through 3 separate lobes, making one big lobe engineered to run with incredible efficiency at higher RPM. Generally, crossover point for a stock vehicle is nearly 5,000-5,500 RPM.

The VTEC engine switches in between fuel-save operating mode & performance-operating mode. Its accomplished by running a lower speed valve-timing & little cam portfolio at lower engine speeds facilitating enhanced fuel consumption & leaner fuel-burning. If the engine requires more power, the VTEC system achieves higher output by pacing up valve timing & switching to bigger camshaft profile that permits further & longer timing for valve opening.

How To Set A Timing Belt

Timing belt is a significant part of your car engine which is meant to control the valve timing. You must be careful about setting up timing belt since it’s a vital aspect of car repair & maintenance. There should be proper synchronization between engine valves & piston to ensure proper operation by the car. An improper setting can result in huge engine issues leading to costly repairs on your part. However, not to worry as the article here is an expert guide on effectively setting the timing belt in your car.


First of all, disconnect the car battery before you proceed to set the car timing belt. Make sure to get the right wrench to remove cable from negative battery-terminal and also remove all the drive belts & brackets which hinder access to timing belt-cover. Now, place the wheel-clocks against any one of rear wheels and position the vehicle in park. It will permit free rotation for the crankshaft.

Turn the car crankshaft clockwise with wrench and socket till the pulley timing-mark gets aligned with TDC or zero degree mark on timing cover. Remove the belt cover and with crankshaft pulley at the TDC, check out on camshaft timing-mark position. The camshaft timing-mark must be directly aligned with timing-mark on rear timing-belt curtain. In case, camshaft marks are not in direct alignment, you would need to make adjustments.

Then, loosen off tensioner bolt enabling free movement of tensioner pulley. Now, pry that pulley away carefully from the timing belt & retighten tensioner bolt. It would relieve tension on timing belt, letting it to set properly. Make sure that your timing belt seems sufficiently loose to permit turning of camshaft sprocket sans moving the timing belt. Loosen off tensioner bolt so that tensioner pulley can tighten up the timing belt.  Your tensioner would be spring-loaded & must apply the effective tension necessary. Tighten up tensioner bolt.

Then, check out alignment of crankshaft & camshaft marks. Turn your crankshaft into 2 full revolutions, returning the crank to TDC alignment. Check out all timing marks ensuring a proper set of your timing belt.

Guides to Understanding Air To Air Intercoolers

Intercooler is one of the indispensable components of turbo-charged vehicles which works to reduce air temperature inside the car engine. The installation ensures a cool and safe engine- hence a great drive. The article here is a brief guide explaining the air to air intercoolers.

Let’s start with the function of intercoolers. Well, there has been much debate regarding how the intercooler works. As per one particular group, an intercooler works like heat sink which absorbs thermal energy derived from incoming air and prevents the unwanted heat from getting to the engine. Another group describes intercooler as radiator where flow of air over the very engine part extracts heat from inlet air-charge.


The fun part is that both the points are correct. Air passing through intercooler doesn’t spend much time inside & slowing that down for better thermal exchange would prevent the air from getting to engine- limitation on power. As air spends fewer spans in intercooler, the engine part comes with multi passages, fins and internal ribs to optimize surface-area contact in between intercooler aluminum & compressed air-molecules. The overall intercooler volume & the overall internal surface area acts akin to heat sink absorbing heat energy from compressed air. Thus, it’s always said that bigger the intercooler, more powerful and functional it is. Besides, more intricate and complex are the internal intercooler passages, more heat would be extracted.

Now, when the vehicle starts out, its intercooler stays cold and gets warmed up with the 1st power run when warm compressed air passes through the system. As the hot air starts running in, heat gets transferred to heat sink leaving out cooler air for your engine. Thus, the intercooler is already heated up post the 1st power run & if there is another power run immediately, your intercooler won’t be able to absorb much heat as it’s heated up beforehand. It’s where the description of intercooler as a radiator fits in. The heat which was passed on from air to intercooler core, should be passed away by cross-flowing the air in air-to-air intercooler.
