1. gasoline or diesel?

That's the first question that makes any buyer of acar. Generally, most people prefer a motorpowered by diesel fuel gasoline for allegedly economyuse but it is not always the case.

If you tend to make more than 20,000 kilometers a year, you wantbuy a diesel car. In a compact, a diesel engine100 HP usually has an average consumption of about 5.5 l / 100 km. Thismeans 100 kilometers will cost about 5.5euros.

2. What is that of 'downsizing'?

In recent years it has become fashionable to useturbocharger to increase performance and, incidentally, theefficiency. The formula is simple: motor leastengine associated with a turbocharger. That is, before useduse a block of 2.0 liters for 130 hp.Now, that figure is achieved with only 1.6 liters. It is what iscalled 'downsizing'.

This has a positive side, in theory a low enginedisplacement, average consumption will be lower but usually thesepropellants are very sensitive to the type of riding you areapply.

Mazda3 SportSedan 2014 (7)

  • Mazda3-SportSedan-movement-SHINARI

    The flowing lines of the Mazda3 SportSedan also drink prototype Shinari.

If you're going to make clear that relaxed driving andyou will not fully tighten the accelerator pedal at all times,you want to buy a small turbocharged engine. Mazda hasdistanced himself from this trend with its SkyActiv technology that usesat higher displacements. Proof of this is the Mazda3 that uses a gasoline engine 2.0 literwith only 120 hp. Yes, it promises an average consumption of just5.6 liters.

3. The turbo engines do not always appeal to you

The previous question has led us to this question: theturbo engines are better? It depends on the case. A motorSupercharged usually offers maximum torque (by denominate ofSomehow, strength) at lower revs. This meanswhich has a higher thrust and is able to recover better from thelower area of ​​the counter.

This feature is evident when recovering: you go80 km / h behind a truck, circulate with the fifth speedstep on the throttle pedal. 175 Nm of torque1,400 laps of a Volkswagen Golf 1.2 TSI pushmore joy than 120 Nm at 6000 rpm of said Mazda3 2.0 SkyActiv. So to speaka clear way to achieve the same strength as Volkswagen, have to stretch the engineatmospheric to 6,000 rpm, that is, should be lowered tothird gear if you want to overtake the truck with verve.

As a general rule, turbocharged engines have a functioningmore efficient but are not always more interesting. Specially inFor sports. Fans of cars highpower transmitting touch prefer a naturally aspirated engine:progressive, soft and full of character in the upper area ofRev counter. A naturally aspirated engine features more sensationssupercharged one.

Also, driving the limit of a propellant turbocomprimidoIt is more delicate for its strong power delivery.

4. What types of supercharging there?

Overfeeding is to introduce an extra amountof air into the cylinders for combustion moreefficient. We can distinguish two types of elements for this:

- Compressor. The best known are the Roots-type. It is aboutan element that rotates the blades through the forceIt produces the crankshaft. That is, usually connected to thiselement through a toothed belt.

- Turbocharging. This element, unlike the compressor,It is set in motion by the force producing gasesescape. It is not connected in any way with the engine mechanical. Byhigh efficiency, is the most widely used system in thepresent.

5. How cylinders are placed?

We are referring to the arrangement of the cylindersengines. That is how these elements are placed? and youadvance that no car is available with an engine of acylinder. Is the world of motorcycles if normal.

- Cylinder inline. It is the most common configuration. usuallycheaper to build and find that the maximum is sixinline. As is the case for many BMW.

- Cylinder V. From six-cylinder and highdisplacements, is the most commonly used solution. Usually operationbe very gentle and hardly presents interior inertia. there areV6, V8 (eight cylinders) and V12 (twelve). Also they have beenV16 engines manufactured huge.

- opposed cylinders or bóxer. The cylinders are facingeach. These blocks stand out for its low center of gravity andthe little space they occupy. These types of engines are veryused by Porsche and Subaru.

6. Better distribution chain

Try to buy the car you have always chaindistribution. This element is transmitting the force from theCrankshaft camshaft located in the cylinder head. The motive isVery simple: the timing chain is maintenance, it isYou may not have to touch anything in over 20 years and beltdistribution (rubber) you have to be replaced every fewtime or kilometers.

Changing the timing belt is a simple jobbut rather laborious and, because it is done, it should changeAlso the water pump (especially if the car is a fewyears). In a stock car, changing the belt comes tocost about 500 euros.

7. What power do I need?

Need 400 hp to go grocery shopping? ACar Engine decide what to choose, it should be clear about the usewe're going to give our car. Every time driversThey apply for fewer benefits, often circulate about 120 km / h inhighway and therefore are not needed many horses.

A few years ago, in the segment saloons like the Mercedes E-Class, which was more estilabaV6 diesel engines of 250 hp. Today, with a Fourcylinder engine with 190 hp is more than enough to move a carthese dimensions. This table can help you to get an ideathe power you need:
