Once cars were scarce. To get them was not easy, to some extent they served as an indicator of status. Times have changed. There are no queues, saved money - bought a car. And if earlier the choice was limited only to products of the domestic automobile industry, now dozens of different brands come from different countries. What brand you prefer is a matter of taste. Which, as we know, is individual. But when thinking about which engine is better, the whole “taste” should be put aside and be guided only by cold calculation.

Not for nothing the engine is called«сердцем автомобиля»

Ведь двигатель является важнейшей частью автомашины. Именно он осуществляет преобразование энергии топлива (в качестве которого может выступать электричество, бензин, дизельное топливо или газ) в механическую. Затем эта энергия передаётся к колёсам посредством трансмиссии. От двигателя зависит: с какой скоростью будет двигаться ваш автомобиль, какой у него будет «аппетит», динамические характеристики. Любая поломка мотора делает невозможной эксплуатацию авто. Недаром двигатель называют «сердцем» автомобиля.Читать далее о том, какой двигатель лучше-->

What are the engines

Is there a choice? In principle, electric cars already exist. Their "heart", as the name implies, is the electric motor. From an environmental point of view, this car seems flawless, because there are no emissions to the atmosphere. But there are disadvantages that cannot be eliminated at this stage in the development of civilization. Electricity cannot be poured into a tank, and batteries (in some cases, fuel cells) provide a power reserve of just a few tens of kilometers. Then they need to be recharged, which is also not an instant process. High and the cost of such a car. Because of all these minuses, electric cars are not yet widespread. But in the future, an electric motor may well become the best engine for a car.

Cars with an electric motor are not yet up to the proper level.

There are options for hybrid power plants. In them, a generator with a drive from the internal combustion engine produces a current that is supplied to the electric motors. But even here, the complexity of the design, coupled with the high cost, do not allow hybrid cars to spread widely.

In the majority of cases, piston internal combustion engines are mounted on production cars. Depending on the type of fuel used, they are divided into gas, gasoline and diesel.

Gas engine

Cars that use gas as fuel are getting bigger every day. Only in our country there are already about 1.5 million. The reason for this is through utilitarian - cheapness. In order not to happen in the country, and the fuel continues to go up. But after going to gas, mileage for the same money can be increased at least twice. This is especially pleased with the heart of the owners of foreign cars, who are forced to pour expensive high-octane fuel into the tank.

More and more motorists are switching to gas

When driving on gas, there is no detonation (its octane number is 105), which has a very positive effect on the engine's durability. Its service life increases and instantaneous combustion of the gas-air mixture in the cylinders. There is no such joint on the pistons and on the head of the block. Savings on oil (it can not be changed longer) and candles. To the joy of environmentalists, emissions to the atmosphere are much less. Plus, it is necessary to take into account that there will be no need for major alterations of the fuel system, which means that the car will be able to work on gas and on gasoline at the driver’s choice. If the contest "The best engines of cars" will be held, then the engine on gas certainly will not be lost against the background of rivals.

There is an involuntary thought about why, with such virtues, not all cars have switched to gas? And the thing is flaws, so far without them. First of all, it is necessary to spend money on the purchase of gas equipment and its installation. This, of course, will pay off, but not immediately. A set of equipment will increase the weight of the machine. Suffer and trunk volume, because there will be a balloon. The engine will lose a little power. However, quite a bit.

When refueling such a car should be especially careful, and leave in the tank about 20 percent of the reserve for the expansion of gas with increasing temperature. Moreover, refueling will take more time. And in the winter when you start the engine will have to switch to gasoline, otherwise you will not start.

Summing up. Advantages of ICE on gas:

• cheap fuel;
• no detonation;
• increases the life of the engine;
• less carbon on the pistons and the block;
• savings on oil and candles;
• harmful emissions into the atmosphere are significantly reduced;
• the engine can run on both gas and gasoline.

And cons:

• high cost of equipment and its installation;
• machine weight increases;
• reduced trunk volume;
• power is lost;
• refueling requires more attention and lasts longer;
• difficulty starting the engine in winter.

Petrol engine

The first efficient internal combustion engine on gasoline was created in the XIX century. To be perfectly accurate - in 1883. His "fathers" were Julius Daimler and Wilhelm Maybach. The engine was very imperfect, it worked unstably. And only the invention of the engineer Donat Banks carburetor (this event was in 1893) allowed to bring it "to the mind." The carburetor was preparing an air-fuel mixture, which was ignited in the cylinders with the help of candles. The carburetor was used in cars for about a hundred years, now it is almost completely replaced by the injector.

Gasoline engine

In our country, gasoline engines have traditionally been considered the best engines for passenger cars. There were serious reasons for this. ICE of this type is easy to start in the winter. For our northern country it is very important. Compared to a diesel, the gasoline engine is not so picky about the quality of fuel Discounts for new cars! Profitable loan from 9.9% installments 0% adom.ru, oil in it can be changed less often. Yes, and repair it in which case it will be cheaper. Adherents of gasoline engines when buying will have a wider choice than the "diesel operators."

The biggest drawback of the gasoline engine is, of course, its “voracity”. And he consumes expensive gasoline. A more complex device (ignition system) causes less reliability. Lower power compared to diesel.

So, the advantages of a gasoline engine:

• easy to start in winter;
• not so picky about fuel quality;
• rare oil change;
• relatively cheap repair;
• wide selection.

Minuses:

• consumes more fuel than diesel;
• uses expensive gasoline;
• more complex, and therefore less reliable;
• has less power.

Diesel engine

Diesel internal combustion engine is actually the same as the gasoline. Rudolf Diesel filed a patent for the type of motor he invented in 1893. And since then, diesel faithfully serves mankind. Its peculiarity is that with a smaller volume it produces more power than a gasoline one. Good traction "on the bottoms" allows you to successfully use a diesel engine on tractors, trucks, off-road vehicles. Diesel is economical, and as fuel uses cheap diesel fuel. Since the fuel mixture is ignited during the auto-detonation process, the diesel engine has neither an ignition system nor a distributor. And the simpler the device, the less it breaks.

Diesel internal combustion engine

A significant drawback is the fuel thickening in the cold. We have to use diesel with special additives. The oil has to be changed about twice as often as the gasoline engine. Yes, and diesel repairs on average is more expensive. The diesel engine is demanding on the quality of fuel. This is one of the main reasons why in Russia cars with it are much less common than in Europe.

Video on how diesel engine works:

Summarize. The advantages of diesel will be:

• high power;
• good traction;
• profitability;
• cheap fuel;
• simplicity of the device;
• long engine life.

Minuses:

• difficult start in winter (thickens diesel fuel);
• frequent oil changes;
• expensive repairs;
• requirements for fuel quality.

If you make the ranking of the best engines for passenger cars in terms of prevalence, then the first place will undoubtedly be taken by the gasoline engine. But the gas engine and diesel, perhaps, will share the second and third places.

Each type of engine has both advantages and disadvantages. Which motor is better to choose? We can only point out the pros and cons. The final choice is yours.
