LaFerrari Engine Review

LaFerrari is one of the latest releases from the Italian automobile giant Ferrari. It’s a hugely acclaimed hybrid sports vehicle which was formally unveiled at Geneva Auto Show 2013. The cutting edge car was also showcased at 2013 Frankfurt Auto Show, one among the most esteemed exhibitions for high end vehicles. The LaFerrari has been designed based on Ferrari FXX testing and the research results derived from Millechili Project by Modena University. It’s said that this new mild hybrid Ferrari car is the most ambitious ventures by the distinguished Italian auto maker- involving finest of marque’s technicalities in both Formula 1 & GT engineering. The article here is a brief review on LaFerrari engine.

The LaFerrari is backed by a super powerful engine producing 963 Horsepower. The car has been engineered with 6262 cc 6.3l V12 naturally-aspirated engine, the supreme most engine ever incorporated in any Ferrari road car. The LaFerrari V12 spins up till 9250 rpm that guarantees an awesome performance & an unmistakable driving pleasure. According to experts, Ferrari has worked a lot on the combustion, mechanical and volumetric efficiency of its new car to offer the customers an unrivalled riding experience.

The engine produces 800 PS (789 bhp; 588 kW) at the rate of 9000 rpm & 700 N-m of torque at the rate of 6750 rpm which is supplemented by 163 PS KERS unit. The KERS unit offer little bursts of additional power. The maximum power produced by the engine is 950 Bhp and the minimum torque is 970 Nm.

It’s to stress here that unlike the traditional hybrid cars where either internal combustion-engine or electric motor is working, LaFerrari’s KERS mechanism adds on additional power to the output level of combustion engine for a net total of around 963 PS- total torque produced by V12 ICE with electric motor is above 900 N-m. Ferrari has claimed that its new hybrid car emits around 330 g/km of CO2.

The engine comes with a 94 by 75.2 mm bore & stroke, 13:5:1 compression ratio & 128 metric hp/l. The snarling engine sound is another remarkable feature of LaFerrari.

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.

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.
