The most modern motor car

Internal combustion engines have changed the speed and distance of moving vehicles, which ensured the rapid development of industry and commerce. This fact became the economic basis for progress in all the aspects of human activity. Today, however, the future of gasoline and diesel engines has come under question. It is believed that most modern engine for the car - it's electric. At worst - a compromise hybrid. And it is not even the issue of global warming. Responsible for this process if the road transport and should, only after the fuel and energy, petrochemical and metallurgical industries, contributing to a more substantial contribution to environmental pollution by greenhouse gases. Limited resources of natural raw material from which gasoline and diesel fuel get - that will inevitably put a cross on the inventions of Otto and Diesel. Which unit will become the successor to the internal combustion engine - izves-TNO. About the upcoming replacement of the thermal thrust on the electrical states at every opportunity. But in the estimates when the tread-bright electric future, opinions diverge significantly. The most optimistic forecast of yield, as a rule, those who are far from understanding the technical issues of the FIR. But according to specialists Comrade directly involved in practically address these issues, internal combustion engines will retain co-lead the fight for at least another two decades. The fact is that even with currently existing technology, self-bil due to energy released during the combustion of kilograms of fuel, is able to travel forty times farther electric field, use the energy of the battery. Simply put - electric-Do not concede a lot of cars in the speed of movement of passengers and cargo. Nevertheless, they returned to civilization in time the penal da distance again have to count the number of stops near steady-state electrical outlets required for subsequent charging airborne ac-kumulyatora. Of course, it's Development Board of Trade and Industry does not help. Meanwhile, the potential of gasoline and diesel engines is still dala-to being exhausted. Since they can still be done fairly modern motor car. After more than 70% of modern gasoline engines equipped with the system Mamie supply with fuel injection in vpus-knoy collector. Just switch to direct injection of gasoline into my chamber combus-of in one fell swoop can reduce fuel consumption by 15% immediately. Thereby proportionately reduce emissions of carbon dioxide, is accused of creating the greenhouse effect. In diesel injection technology also plays a crucial role in reducing fuel consumption and emissions. Here, expectations are also associated with an increase in pressure and change in injection scheme. Also in gasoline engines is still not enough is widely used turbocharging system and governance valve timing. At the same time in combination with turbocharging by the Office valves would ensure Chiva in engines working volume of only 1.4 liters of the characteristics of the current 2-liters of new powertrains. Finally, according to experts, when time passed, more active use of the Start / Stop automatically stops the engine when you stop the auto-mobile at a traffic light or in traffic. Also saves the system temperature control, which allows the motor warms up quickly and then work-thief in the optimal thermal conditions. Another promising system theme, recovering energy that is released when braking the car. Only because of the listed metal-frame we can make the car a mass of 1400 kg with a gasoline engine power of the 100 kW consumes today, on average 7.7 L/100 km of fuel will consume only 5.5 l/100 km. A diesel model of the same weight and power - 3,5 l/100 km. Impressive, is not it? But to reduce fuel consumption and harmful emissions can be even with the help of technology, not related to the engines. For example, by reducing overall vehicle weight, reduce aerodynamic drag and the chemical resistance of rolling. Implementation of these measures, of course, require money and affect the cost of cars. However, any of them, this fight - just another step in the evolution of the internal combustion engine. They knew the history of technological break-up, far more serious than, for example, a change in injection scheme. And compared to how the cost of Batteries-ditch, providing an acceptable pro-run, increases the price of electric vehicles and how large investment required for the development of battery technolo-gies, the improvement of internal combustion engines is more economically feasible. On the other hand, stocks of hydrocarbon raw materials native in any event not infinitely. Translation engines on habitat-showers "diet" together with works to reduce fuel consumption can only move in time the need for introducing an electric alter-native's. However, if an inexpensive and easy battery with a capacity that ensure the independence of the socket, with the auto-postavimuyu autonomy-her, and will not be developed, not excluding Chenoa, that the triumph of electric vehicles, we do not wait for ever. Perhaps, indeed most modern motor car is a hybrid. He has a chance to become the dominant trans-tailor the technology movement in space. Although today a hybrid drive consider only as an intermediate step towards the complete electrification of transport. And the work of the hybrid leads to the so impossible without the use of motor-Chairman internal combustion engine. Means that Kim motors there is a place on board gibridomobiley. Today in serial hybrid cars heat engines combine the functions of the traction motor and a battery charger for battery electric trodvigatelya. And in the future engine of internal combustion, obviously, will switch to only charge the battery. Such a solution would, firstly, to simplify the transmission. Since there will be no need to pursue-Xia teamwork of the two power-boiler systems, as in the current "hybrids". Secondly, with the responsibilities of the charger can handle a small shoy petrol or diesel engine capacity from 15 to 35 kW. This engine itself is economical, besides constantly This work was he would have in a stationary and unloading mode for which is just the most basic characteristic of Uro-Wen fuel consumption. "Hybrid" battery does not require the same capacity as a pure electric vehicle, thereby reducing battery weight and cost. Finally, the autonomy of the Nogo-hybrid car only limits it is necessary to visit the salad on the filling the fuel tank. Therefore, the "hybrid-Reed is able to perform not less mileage than a regular car. In the foreseeable future, most modern motor car will be fuel cell assembly. That is, the electron tromobil will use the energy, we obtain the electrochemical decomposition Institute hydrogen in fuel cells. But then all depends on the value of technology. And it is in the case of the fuel cell while so high that say when this technology could be suitable for mass production sovogo not taken any one person. Rumors about the imminent decline of the same era of internal combustion engines, most likely exaggerated.
