According to market forecasts, at the end of this year Saab will mark the most successful year in its history. Paradoxical as it may sound, but success is due to ethyl alcohol ...
Scandinavian Motors recently introduced a model in Bulgaria, so anyone can buy it, but unfortunately you won't be able to fully exploit its potential yet, because there is simply nowhere to load ethanol in our country. Unfortunately, because burning ethanol releases less pollutants into the atmosphere, growing raw materials for its production balances CO2 emissions from cars, and its local production is especially valuable for the budgets of countries without oil reserves. Since Bulgaria is one of them, it is certainly a good idea to use the experience of European countries such as Sweden, where alcohol as a vehicle fuel has a strong market position, or Hungary, which is currently developing a system of tax incentives for ethanol vehicles. and clean refueling infrastructure.
It is neither a coincidence nor a coincidence that some oil companies have recently embarked on the search for efficient methods of alcohol production - a typical example of this is the collaboration between Shell and the Canadian company Iogen. The goal of the joint project is the production of so-called "eco-ethanol", which does not use other types of processing of grain or fruit mass of plants as raw materials, but uses only pulp. From a chemical point of view, the process of obtaining ethanol from cellulose, and not from carbohydrates, is much more complicated, but the practical benefits from its implementation are incredibly higher than from classical distillation.
In one of the previous issues (04/2006), we introduced you in detail to the qualities of alcohol fuel, and therefore here we will only note that in the history of automobile alcohol it has repeatedly figured on the agenda as a possible alternative to petroleum products and even enjoyed the support of such factors as Henry Ford. but in the end, the circumstances were always in favor of oil. There is no period of oil hysteria when ethanol is not seen as a potential lifeline, but the very first attempts to alleviate the situation and discover new oil fields again sent it behind the scenes. This cycle continues to this day ... Saab is currently preparing a version of BioPower for the 9-3, gradually becoming one of the most active promoters of the idea of alcohol ...
Saab and ethanol
Their task is likely to become easier because it is a fact that ethanol-powered cars have more than just environmental benefits. Thanks to the high octane number of ethanol, designers have the ability to increase the turbo pressure in alcohol mode and with the BioPower-optimized Trionic integrated electronic process control system (control of turbocharger pressure, injection and ignition) to increase the power 9-5 BioPower up to 30 hp with., reaching 180 instead of 150 horsepower in the 9-5 with a standard gasoline engine. Thanks to this, the world's first serial "turbo-alcohol" car achieves significantly better dynamic performance when working with ethanol, the engine runs smoother, increases speed more easily and responds more spontaneously to acceleration. Due to better elasticity, even an excessively long fifth gear of the transmission becomes a plus - in gasoline mode, a large station wagon reacts rather sluggishly to gas when driving at high speeds, and with a full E85 tank, the Swede does much more. dynamic impression. Therefore, in the Saab model, there is no theoretical increase in consumption of about 30% when using the E85 - in petrol mode, the driver is forced to downshift earlier, and a higher compressor pressure improves engine efficiency. Ultimately, the owner of a Saab 9-5 2.0t BioPower can save a lot of money from switching to a fully operational vehicle from the E85.
