Quality OIL

Quality Motor Oil Premium

The Mobil Super FE Save Fuel are formulated from high quality base oils combined with modern performance additives to give your engine the proven protection and performance you expect under a wide variety of operating conditions, resulting in a long engine life. This advanced technology lubricant contains performance additives to help protect engines during 7500 km oil change or 6 months, whichever comes first. These motor oils provide more efficient fuel consumption because they are classified by the API as engine lubricants "Conservatives Resource" and meet or exceed the industry specification ILSAC GF-5 / API SN latest. These specifications are compatible with earlier performance levels such as API SM, SL, and SJ and previous ILSAC categories. The Mobil Super FE Fuel Save Available in two viscosity grades of multiple multi-viscosity: SAE 5W-20 and 5W-30.
 

Today a good oil SAE 5W-30 or SAE 10W-30 maintains more than 3.3 cP at shear test simulating the actions in the camshafts, bearings and rings, where 10 years ago I just had to keep 2.9 cP . This represents more than 10% improvement required where the engine without increasing its nominal viscosity, or resistance without increasing fuel consumption. or mean we have almost as much protection viscosity engine parts (bearings and camshafts) with a 5W-30 oil that we had a 40 SAE 10 years ago. or at the same time, the SAE 40 do not readily pumped into the motor. An SAE 5W-30 has the same flowability and pumpability at 0 ° C for a SAE 40 at 23 ° C. or does not mean that all engines requiring SAE 5W-30. You should read the manual and implement the "preferred" viscosity by the manufacturer.



Some people look at the graph of the difference in viscosities (above) and this problem does not relate to the actual oil viscosity. The line represents what happens to viscosity. The problem for the engine is the lack of movement of a viscous oil as the strainer and the oil passages for eventual arrival at all points of the engine. Several studies show a difference of up to 3 minutes between the time a SAE 5W-30 oil reaches the last point of the engine and when it reaches zero the SAE 40 degrees Celsius. The viscous oil which eventually reaches, not passing through the filter.

 Go directly carrying dirt filter for the relief valve open pressure. And how many people tear your engine with viscous oil and begins to operate normally, without heating When choosing oil viscosity must limit the covered range (between the first and the last number) when the oil is not synthetic. The higher the rank of the viscosities, there are usually more polymers.

Transmission sequential

Transmission sequential 6-speed Powershift

The advanced transmission Powershift 6-speed Sequential comes equipped with dual clutch making the changes with the exact precision to which the passage run fast and fluid, without interrupting the flow of power and working efficiency of fuel consumption.
Thus, it offers a more sporting and comfortable driving, combining all the performance of a manual gearbox with the convenience of an automatic.
The Sport mode allows changes happen sequentially using SelectShift button.

Manual transmission: The new Fiesta also has a manual five-speed transmission modern mechanical and riding pleasure.
The gear ratios have been specially designed to provide a strong start to the ride and outstanding fuel economy of gait performance.

Basic Functional Description
When starting the engine, the gears are disengaged and clutch coupling the rotation of the motor. Assuming that the automatic mode is selected, the electronic system operates both clutches and sets the first gear. When you stop pressing the brake pedal, knob partially engages the clutches for the odd gears shaft, causing movement of the vehicle in first gear when the accelerator goes completely closing the odd clutch at the same time, is placing second gear pairs in all gears.

When you reach the speed needed for the gear shift, the system disengages the clutch engages the odd gears and gear pairs, wherein the second gear already selected. At the same time, the set of odd gears third gear is selected, leaving the gear ready for when the engine reaches the speed in which it is necessary to do the gearbox again.
Here again the clutch change is repeated, and third gear is engaged and the set of pairs is released for the system to place fourth gear. So you get to sixth gear with very little loss of time between changes, without the need for a torque converter as in conventional automatic transmissions.

This is the process that will speeds engaging in a process of acceleration but not the same process when decelerating. The operation is based on that while a gear is engaged, and connected by a corresponding clutch is engaged too, although disconnected, the top or bottom. The method that is used to engage the top or bottom is easy. If the engine is accelerating until the engine speed when changing to a higher gear it engages, if instead the engine is slowing down gears will engage because they understand that you want to insert a lower ratio.

Hybrid Engines

Hybrid Engines

What are hybrid engines? 

When we speak of hybrid motor we refer to two types of different, commonly electric power and gasoline, that influence to generate the movement of the vehicle. The most common are the parallel hybrid called. In them, the two sources of power work together, separately or in parallel. The invention of hybrid engines were a major challenge for engineers, since they must have produced a car that save gasoline and keep the high speed. This should be possible only with an electric motor, a small engine, and a great pair of batteries to spin the wheels. The key for engineers was maximize the performance of the gasoline, and maintain charged batteries that never need to be recharged. The energy provided by about 2 liters of gasoline requires approximately 205 kg of battery.

Operation of a hybrid engine 

A set of gears leading to a chain that connects the wheels of the car. In particular, produced a delicate interaction between gears that determines how much fuel burned car. When the movement begins, the electric motor rotates the outer gear, and this gives you speed without wasting a drop of gasoline. When you win speed, the gasoline engine starts to participate. 4 the power splitter gears start to turn and increase the power of the car. There is a central gear which also kicks in; It is connected to a generator that charges the batteries, and sent extra power to the electric motor. The technology of hybrid cars includes internal monitor that indicates what type of power that is working. The operation of electric cars is ideal for urban, but on road, electric car will need as much, a couple of thousands of kilometres to achieve a complete recharge. Hybrid cars have the advantage of burning gasoline with maximum efficiency, and recharge the battery without compromising power.

Transmission CVT

Transmission CVT

A continuously variable transmission (CVT) is a transmission that can change seamlessly through an infinite number of effective gear ratios between maximum and minimum values. This contrasts with other mechanical transmissions that offer a fixed number of gear ratios. The flexibility of a CVT allows the input shaft to maintain a constant angular velocity.

A CVT usually has a low efficiency of 88%, but it can provide a cheap automatic gear solution by enabling the engine to run at its most efficient revolutions per minute (RPM) for a range of vehicle speeds, allowing a small car (CVT can't handle high torques[need quotation to verify]) to have an acceptable fuel efficiency at low cost.

Alternatively, it can be used to maximize the performance of a vehicle by allowing the engine to turn at the RPM at which it produces peak power. This is typically higher than the RPM that achieves peak efficiency. Finally, a CVT does not strictly require the presence of a clutch. Nevertheless, in some vehicles (e.g. motorcycles) a centrifugal clutch is added, to facilitate a "neutral" stance, which is useful when idling or manually reversing into a parking space.

Uses

A Chain-driven CVT

Many small tractors for home and garden use have simple rubber belt CVTs. For example, the John Deere Gator line of small utility vehicles uses a belt with a conical pulley system.CVTs should be distinguished from Power Sharing Transmissions (PSTs), as used in newer hybrid cars, such as the Toyota Prius, Highlander and Camry, the Nissan Altima, and newer-model Ford Escape Hybrid SUVs. CVT technology uses only one input from a prime mover, and delivers variable output speeds and torque; whereas PST technology uses two prime mover inputs, and varies the ratio of their contributions to output speed and power. These transmissions are fundamentally different.

The Ford C-MAX hybrid, Ford C-MAX Energi hybrid, Mitsubishi Lancer, Proton Inspira, Honda Insight, Honda Fit, and Honda CR-Z hybrids, the Nissan Tiida/Versa SL and SV models), Nissan Versa Note (S Plus and higher), Nissan Cube, Juke, Sentra, Altima, Maxima, 2013 1.2 Note, Rogue, X-Trail, Murano, Sunny, Micra, Honda Capa, Honda Civic GX (CNG), Honda Civic Hybrid, Honda Accord, Jeep Patriot and Compass, and Subaru Forester Impreza, Legacy and Outback, Dodge Caliber, and Toyota Corolla offer CVT.

Types

Variable-diameter pulley (VDP) or Reeves drive

In this most common CVT system, there are two V-belt pulleys that are split perpendicular to their axes of rotation, with a V-belt running between them. The gear ratio is changed by moving the two sheaves of one pulley closer together and the two sheaves of the other pulley farther apart. Due to the V-shaped cross section of the belt, this causes the belt to ride higher on one pulley and lower on the other.

Toroidal or roller-based CVT (Extroid CVT)

Toroidal CVTs are made up of discs and rollers that transmit power between the discs. The discs can be pictured as two almost conical parts, point to point, with the sides dished such that the two parts could fill the central hole of a torus. One disc is the input, and the other is the output. Between the discs are rollers which vary the ratio and which transfer power from one side to the other.

Direct injection engine


Pollutant emissions of hydrocarbons, nitrogen oxides and carbon monoxide are reduced up to 99% with the mediation of a three-way catalyst.
Meanwhile, carbon dioxide (CO2) produced as a result of combustion, being the cause of the "greenhouse effect", can only be reduced based on lower fuel consumption.
Considering these factors, we see that the injection systems with external mixture formation (injection into the intake manifold MPi) are not used to meet these goals, hence the need to develop a system able to meet these commitments. This system is the engine with fuel injection.
Engines with direct fuel injection two main objectives are valid for today and for the future are achieved, these goals are to reduce fuel consumption and this also polluting exhaust emissions.
The different car brands increasingly are choosing to equip their models with gasoline direct injection engines. First it was the Japanese Mitsubishi GDi engine with, now followed with IDE Renault engines the PSA Group with HPi engine, and Volkswagen with FSi engines.

If we compare the fuel injection system on the manifolds (also called indirect injection MPI) with direct fuel injection, we understand why the latter is higher than the first. Injectors gasoline engine (MPI) are often located in the intake manifold, which explains the name of these systems. The fuel is injected in front of a closed or open up the valve and is almost completely mixed with the intake air in each of the nozzles of valve manifold. But this mixture of air and injected fuel mist does not allow perfect explosion in the cylinder if it is not prepared in accordance with a precise stoichiometric ratio comprised within very specific limits

 
In systems of direct fuel injection, fuel is injected directly into the combustion chamber and not in the manifold or intake port, which offers advantages in story to engine efficiency.
The fuel injection systems of gasoline were developed several decades ago by a bomb he was carrying fuel to an injector placed in the combustion chamber, however the problems presented by the high cost and emissions.
Other important features of this system, and the position of the injector in the combustion chamber are:
Precision injection time: In indirect injection engines, is not as important a time when fuel injection is performed, however, direct injection injection should be done at the stage of admission and / or compression.
High pressure injection: The fuel must be injected at high pressure to facilitate spraying and proper mixture with air. 

Piston head: The piston head has forms that allow the formation of turbulence within the combustion chamber to improve air-fuel mixture and / or direct the mixture at a specific space as close to the spark plug, to improve combustion. 

On some engines, direct injection stratified charge that fuel is injected at two times, the first time, in the intake phase and the second compression is used when the air is located near the spark plug, which causes the mixture turns which is close to the plug, leaving the rest of the lean cylinder with light, only expands, this combined mixture is used when the engine was not require too much power, as may be the case city ​​or when traveling at constant speed on level ground. Moreover, the combustion takes place near the spark plug and the rest of the mixture to swell only produces a lower temperature in the cylinder wall to improve engine performance.
