New Engine Needs a Shot of the Hard Stuff
The Ford Motor company have just revealed the test results of a new ethanol assisted engine that looks set to compete with Hybrid technology. The news coincided with president Barrack Obama’s announcement of new regulations that require the fuel efficiency of all new cars and trucks to be improved by 2016.
The new engine, called a direct-injection ethanol engine, runs primarily on petrol. When the engine needs a bit more power, perhaps to go up a hill or overtake, then the ethanol injection kicks in.
This results is an improvement in fuel efficiency of around 23% for an average car. This is due to the fact that the engine operates at a higher compression ratio. The compression ratio is a measure of how much the fuel and air mixture is compressed before being ignited. Higher compression ratios would normally result in premature ignition which is commonly called knocking. Adding ethanol to the fuel-air mixture suppresses knocking.
A pick-up truck fitted with one of the new engines, along with an additional ethanol fuel tank, showed a 23% improvement in fuel efficiency while maintaining performance levels. It was estimated that a 40 litre auxiliary tank of ethanol would last for around 30,000 kilometres.
It is expected that the next phase of testing and evaluation will see the new engine used in a variety of vehicles. More testing is to be carried out to assess whether the new ethanol assisted engine becomes unstable when the ethanol runs out.
A key factor in favour of this new technology is that the extra cost of these new ethanol assisted engines is around one third of the extra cost of a hybrid petrol-electric engine. Hybrids typically deliver an improvement in fuel economy of between 25 and 35%. The new direct-injection ethanol engine looks like it is a strong contender that will meet Obama’s projected fuel efficiency figures.
It was on May the 19th when Barrack Obama announced at the White House: “The goal is to set one national standard that will rapidly increase fuel efficiency, without compromising safety, by an average of 5 percent each year between 2012 and 2016″.
The new rules would require vehicle’s average fuel economy standards to be 35.5 miles per gallon by 2016. Specifically, an average of 39 miles per gallon for cars and 30 miles per gallon for trucks. For reference, this year (2009) the average fuel efficiency is 25 miles per gallon.
Inevitably, these new regulations will mean additional costs for motor manufacturers which will be passed on the consumer. But although people will be paying more for their cars and trucks they will be paying less for fuel. Obama said that it was estimated that the average driver would save as much as $2800 by improving their gas mileage.
One way that anyone interested in a new car can save money is to consider financing their new transport using a car lease. Car leasing offers personal and business customers many advantages over outright purchase. Looking out for new model Fords using the new direct-injection ethanol engine on a Ford lease could be a practical way to save a small fortune.
