For decades, "war" is "war" between diesel and gasoline engines, to refute the existence of which is meaningless. Nowadays, many automakers equip the same models of both diesel and gasoline power plants, therefore it is not possible to say that the same type of motor type is preferable. Since the opinions of specialists disagree, in this article we will look at all the advantages and disadvantages of gasoline and diesel engine, which will help to understand which one is better to choose.

Car engines, what they happen

The following types of car engines are exist:

1. Diesel.
   
2. Petrol.
   
3. Gas.
   
4. Electric.
   
5. Rotary-piston.
   
6. Gasiodials.
   

In addition, the power units are classified by the location and number of cylinders, by type of fuel, in terms of the number of operations of the engine, according to the method of formation of the fuel mixture, and so on. However, diesel and gasoline engines are the most common.

Fuel consumption of diesel and gasoline car, comparative analysis

The specific fuel consumption is an indicator of an efficiency that determines how much fuel is consumed by the motor with a power of 1 kW in one hour. The specific consumption of fuel is higher for gasoline engines. For diesel engines, it is 200-230 grams, for gasoline - 265-305 grams.

In addition, a fuel injection diesel occurs immediately into the combustion chamber, respectively, its losses are minimal. In the gasoline engines, the air is mixed with fuel in the intake manifold.

Torque of diesel and auto on gasoline

Gasoline motors are shortached, rather than diesel, resulting in a smaller torque. If you need an excellent traction and you often transport large loads, it is better to give a preference to diesel - it has a substantially higher torque, which is implemented in full due to the high degree of compression required for the self-ignition of diesel fuel.

Maximum power, who has higher

Although gasoline power units have a smaller torque, they are able to produce high power and unwind to large revolutions, due to which they have excellent acceleration dynamics. Combining with them for this parameter can only just modern diesel engines with turbocharging.

Reliability, comparative analysis

The diesel engine is considered more reliable than gasoline, which is due to the peculiarities of its design, which involves a reduced combustion temperature, fuel stability and work on small revolutions. However, some engines are distinguished by a relatively low service life - especially this concerns vehicles of the recent years of release, in which diesel engines have a large amount of electronic equipment and a high degree of forcing. But despite this, classical power plants prove the excellent durability of diesel engines.

Repair, where more and more difficult

Although, with proper operation, diesel engines wear less gasoline and more durable, in practice they break quite often. In addition, the repair of the diesel engine is more expensive, due to the complexity of the design and the large cost of spare parts. As a rule, spare parts for gasoline engines are much smaller, and a specialist who will be for this work, to find much easier.

Purchase price, which is more expensive, and why

In diesel engines, the compression ratio is much higher, so the block head, crankshaft, rods, a block of cylinders, pistons, and so on are experiencing higher loads, resulting in suitable must be reinforced. In effect, the cost of diesel engines lose with gasoline analogues.

Service cost, what is the difference

In Russia, as a rule, problems with a diesel engine arise due to the use of poor quality fuel. Oil and filter have to be changed quite often. Also, trouble can occur during repair, as the diesel engine is complex design. Cars on gasoline to a lesser extent react to the quality of fuel. The power and turnover of the motor is quite high, and spare parts for repair are more accessible.

Maintenance period

Unlike gasoline engines, the frequency of maintenance of diesel is significantly less. Thus, the replacement of motor oil and the oil filter in the diesel should be carried out every 7.5 thousand kilometers of the mileage, in the gasoline engine - every 10 thousand kilometers.

Durability of diesel and gasoline car

The gasoline motor operates at higher revolutions than diesel. The working range of the diesel power unit is usually limited to 5000-6000 rpm, when gasoline is spinning to 8000-9000 revolutions per minute. Diesels are more durable, but only under the condition of proper operation.

As a rule, gasoline engines go to overhaul only three hundred thousand kilometers when some diesel engines can pass without serious intervention already up to a million kilometers.

How to find a good mechanic to maintain diesel

As already mentioned above, as a result of the complexity of the design of the diesel unit, finding a good autoslemer is not so simple. Contact only the tested auto repair shop to highly qualified specialists to avoid problems in the future.

Winter fuel of good quality, why it is important for diesel

In diesel units, the fuel system is very sensitive, so it is necessary to use high quality fuel. If a low-quality fuel will fall into the system, it instantly occurs in the paraffin crystals, which are clogged by filters and fuel pipes, as a result of which the vehicle will stroke on the go.

Diesel and gasoline car speed

The speed of maneuvering in a car with a diesel engine is much greater than the car with a gasoline power unit. This is explained by the fact that the diesel is above the torque and it is achieved on low revs. Thanks to this, the driver does not have discomfort when maneuvering in a roadflow.

Warming in the cold time, who has longer

Probably, everyone knows about the problems of a diesel unit in frosty weather. In the diesel, the fuel is self-proposal using air heating during compression. At a temperature of less than thirty degrees Celsius, air can not warm up to the operating temperature to ignite fuel. To circumvent this problem, the heat candles are used in the dieselle, which heat the combustion chamber before starting to the desired temperature.

With a gasoline engine in winter, this is excluded. Fuel is stably flammable from the spark, which provides easy start. The driver should only choose the proper motor oil and follow the charge of the battery.

Exhaust toxicity, who worse

Since the fuel combustion indicators and efficiency of the diesel engine are higher, there are fewer harmful exhausts than in gasoline.

Results, pros and cons willing

Advantages of diesel:

1. Small fuel consumption.
2. Work without a traver and spark plugs.
3. Very good traction with small revs.

Disadvantages of diesel:

1. Sensitivity of the fuel system.
2. The presence of vibration and high noise characteristics.
3. The needs of more frequent replacement of filters and oils.

Benefits of a gasoline engine:

1. Low vibration and noise characteristics.
2. Work on big turns without comments.
3. High liter power.

Disadvantages of gasoline motor:

1. High fuel consumption.
2. The need for spark plugs for work.
