Hybrid Drive or Four Wheel Drive in a New Fashion

Farewell, petrol!

Each rise in petrol prices and toughening of the cleanness exhaust gases requirements pursue car manufacturers to develop economical and environmentally friendly vehicles. Thus is the 90s of the previous century, the company GM created a small batch of electro mobiles EV1, which were to become a pole in the history of car making. However, due to the high cost of cars, very modest power reserve (about 160 km) and the main thing was the absence of a generator which enabled the driver to move on dead batteries, the cars were unpopular. Ultima analysi the production was swerved and the exploited models were recalled and deconstructed.

Nevertheless, research and works on concepts on electric draft didn’t stop, and the potential was realized in the new concept-car - Chevrolet Volt. This 4-seat limousine of “muscular” build was the first car to be equipped with a new generation of electric transmission by GM. As the accumulator of electric energy the constructors used the modern Li-ion batteries which can be recharged with the help of a generator inbuilt into the petrol engine. The hybrid scheme of the power unit created be the engineers significantly increases a car’s run on a single recharge.

Thus, with completely charged batteries a car can cover up to 60 km. As soon as the hand of the ammeter reaches the red zone, the automatics starts the 3-clinder turbo engine with the displacement of 1 liter which in its turn start the generator. It should be mentioned that the automatics chooses the mode which makes the harmful emissions and fuel consumption as little as possible and the figures of power and torque are vice versa maximal. Owing to the refined work of the transmission the car shows miracles of economy.

Let me give you an example. Let’s assume that you live 50 km from your work – thus the average daily run of your car will be around 100 km. Taking into consideration that you have to start the engine (and the generator) to recharge batteries you will consume 1.6 liters to run these 100 km. Those lucky men who live closer than 30 km to their work can avoid using petrol at all. The major thing is to recharge the car when you come to work. The thing you’ll need to this is an outlet with 110 V. And what happens if the driver forgot or cannot recharge the batteries? Nothing awful. The hybrid drive enables driving the car for 100 km consuming 4.7 liters of petrol. And the trip on one filling will make around 1030 km (which is twice the trip of the traditional cars of the same class).

Still, hybrid drive is not the only means of economy. You can economize on fuel itself. Thus you can use mixture of 15% petrol and 85% ethanol as fuel for Chevrolet Volt. In perspective there is a possibility of creating hydrogen power units, bio-fuel diesels or petrol engines that work on ethanol.
