Classification of modern cars
All modern cars can be classified according to a variety of features:
engine type, its volume, body type, drive axle, etc. The ability to separate cars according to key features will allow, in particular, to adequately formulate their requirements for the future car before it is purchased, and also useful in many other cases. In this article we look at the most common classifications of modern cars.
Car classification by engine type
All cars, depending on the type of engine installed can be divided into two categories: working on gasoline or working on diesel fuel, shortly – gasoline and diesel. Despite the fact that those and others have a lot of fans, and disputes about the advantages and disadvantages of each type go on for many years, no one will say that it is better: gasoline or diesel.
Perhaps the reader will have a question: “As for gasoline cars, everything is clear, but on what kind of fuel do diesel cars work?”.
Diesel fuel is diesel fuel, which also includes tractors and other agricultural equipment, military equipment, diesel trains, and others.
It is no secret that in modern Russia many motorists refuel not at gas stations, but “by acquaintance”, in other words, they buy stolen fuel. Remember that the highest quality diesel fuel is for the machinists, as well as for the military: after all, for these consumers it must meet special requirements, in particular, to be reliable at low temperatures. It is not recommended to purchase diesel fuel from tractor drivers, as well as from unknown people: if it still comes down in the summer, you can stall at the most inopportune moment in the winter.
The principal difference between a gasoline engine and a diesel engine is that in a gasoline engine the fuel burns off the spark that the spark plug produces, and in the diesel engine it ignites from the glow plug. Note that the diesel engine is much more expensive to produce – its cost is about 25-30% higher than that of a gasoline engine. This is due to you, first of all, an extremely complex production technology: when performing certain operations and technological processes, it is necessary to observe just space accuracy.
But in operation, most diesel engines are more economical than their gasoline counterparts (the difference in fuel consumption per 100 km of run can be from 2 to 5 liters). On the other hand, “diesel engines” are inferior to petrol engines in pickup: petrol cars behave more briskly on the road (by the way, this is why there are almost no cars with a diesel engine among sports cars).
In winter conditions, the diesel engine may be unreliable: it is no secret that at low temperatures diesel fuel thickens, and the car just stalls. However, this applies primarily to old cars; on modern cars, all the features of a cold climate are taken into account, and the “diesel” in terms of reliability does not lag behind the petrol engines. The main thing is to fill in high-quality fuel, and in the cold season to drive on the “winter” diesel fuel.
Car classification by drive type
Why is the car moving? Because the thermal energy of combustion, which is formed in the engine, is converted into mechanical energy of rotation, which in turn is transmitted to the drive wheels, and they are already driving the car. Depending on which wheels of the car are leading, all cars can be divided into three categories: front-wheel drive, rear-wheel drive and all-wheel drive.
In front-wheel drive cars leading is the front pair of wheels. A characteristic feature of these cars is their lack of a cardan shaft. Front-wheel drive cars are characterized by high maneuverability, as well as the possibility of easier exit from a skid.
Rear wheel drive cars are driven by a rear pair of wheels. In this case, for the transmission of torque from the engine to the wheels, a cardan shaft is used, which extends from the front of the car to the rear axle. Note that in the former USSR only rear-wheel drive vehicles were produced for a long time; the first front-wheel drive car to make a kind of revolution in the domestic automotive industry was the VAZ-2108. These cars began to go off the assembly line in the second half of the 80s of the last century. Note that many Russian motorists with experience still fundamentally drive only rear-wheel drive cars.
As the reader probably already guessed that all-wheel drive cars are those whose driving wheels are all four wheels. Note that if necessary, the driver can disable any drive axle – for example, in order to save fuel.
Among the Soviet cars, the first all-wheel drive car became the famous “Niva”. By the way, she didn’t have a constructive shutdown of any bridge. However, domestic motorists quickly found a purely “Russian” outlet, which was simple, like all ingenious: they simply removed the “extra” drive shaft.
