Turbocharged engine - high performance fuel comes? ~ car loan

Some automakers said the turbine booster they provide fast acceleration, fuel savings, but the fact should be considered.


Car Booster allows manufacturers to keep high power output while the engine more compact than the target fuel economy. But mostly just some miles / gallon proud when people lose control gas pedal and enjoy the supercharged performance that brings.

System pressure will develop extensively by vehicle manufacturers to reduce the size of the gasoline engine to meet environmental safety standards is gradually tightening. Estimates of vehicle integrated supercharged engine will account for 25% of all new vehicles in the North American market in 2017, according to LMC Automotive estimates. But the limitations of pressure as fuel for the many opportunities for diesel engines, hybrid and electric motors in the coming years.

The impression from some of Ford Motor Co. advertising. suggests automakers are eager to promote fuel-saving potential of turbocharged EcoBoost engines. The name itself implies that the engine has a turbo turbine combined fuel economy (Eco) and performance (Boost).

With Chevrolet, a large banner on the site recently introduced Cruze Eco model with a 1.4-liter turbocharged engine with fuel consumption of only "42 miles / gallon and not sacrifice pleasure" shows the vehicle can still ensure savings even if the driver uses pressure regularly.

The actual number
 
Despite the marketing campaign for the ability to save the supercharged engine, the actual number reflects the opposite.

For example, Dodge Dart cars with 1.4-liter turbocharged engine parameters reach 39 miles / gallon on the highway according to the EPA. But the real test of the recent Car and Driver magazine, Dart scored less than 39 miles / gallon by editors attached a fuel gauge on the car in order to get accurate results about the possibility of savings. According to the magazine, at speed of 120 km / h on the highway and the air conditioning is on, the car computer shows only the average consumption of 33 miles / gallon. To increase this number approximately 40 miles / gallon will require patience and a lot slower.

 "When it comes to pressure, we often think of the performance, but as soon as you drive, the ability to save more fuel poor" - Mike Omotoso, senior manager for powertrain forecasts of LMC Automotive said.

Consumer Reports recently tested 11 models with increasing pressure from 7 different vendors to test the ability to save fuel. Results for route combines city streets and highways that reach all the vehicles are just a few of the less miles per gallon than the EPA estimates.

Also, in terms of economy, consumers often must pay at least 1,000 USD for the supercharged engine which, in many cases, after the calculation, not fuel economy in conventional engines.

Honda car company has quietly removed turbocharged 4-cylinder, 2.4 liter capacity models Acura RDX 2013 and replaced the engine with a larger turbo to better fuel economy. Turbocharged engine, according to the EPA at 19 miles consumption urban / highway 24 miles / 21 miles per gallon combined fuel was replaced with a V-6 3.5 liter capacity with consumption of 20 miles city / 28 highway miles / 23 miles combined.

The site's editors have put pickuptrucks.com two Ford F-150s in a traction test, an engine using turbo V-6, the rest use a V-8 text volume 5.0 liters. The winner of the competition on fuel economy in larger engines, 9.4 miles / gallon for V-8 engines over 7.2 miles / gallon with V-6 EcoBoost engine.

However, a spokesman for Ford said customers are completely satisfied with your turbos pickup F-150. Fuel economy is the top criteria to consider when selecting clients EcoBoost engine. The data show that, F-150 leads the list of light truck makes customer satisfaction for the economy.

Ford has been very active with turbos. Approximately 80% of car dealers in North America available EcoBoost engine options, a combination of turbocharger system with direct fuel injection and other technologies. The carmaker has sold more than 600 thousand cars in this market with small turbocharged engines under the EcoBoost name. More than 400 thousand cars of which the F-150.

Small engines in large cars
 
An experience for you while shopping, take your message to the EPA that the evaluation of the car manufacturer made. The tests showed that the actual number is not so precise.

So why only the fuel economy of the turbocharged engine in practice is not as beautiful as assessed by the EPA?

Booster system, usually mounted on or near the exhaust, air operations based on emissions when the engine operation to turn a small turbine with a very high speed. The turbine compressor to run a mixture of air and fuel injected into the cylinder, this allows smaller engine and still provide a lot more energy.

But the increasing pressure operation, fuel savings decline, sometimes quite significantly.

Also, some car manufacturers use a trick with the evaluation system miles / gallon by utilizing EPA test procedures of the agency. Some vehicles are adjusted to provide the highest savings based on EPA test procedures that do not match the actual driving conditions. With testing on the highway by the EPA, the car will run for about 12 minutes with a maximum speed of 97 km / h (60 miles / h) and the average speed is 78 km / h (48.3 miles / h). Such a low rate would make the results mile / gallon high for supercharged engines.

Not to mention the reason small engines in large vehicles, such as turbocharged 4-cylinder, 2.0-liter capacity of the Ford Explorer weighs about 2 tons, usually do not have the ability to accelerate quickly as drivers always wanted. The gas pedal is the more powerful, using more pressure, the more frequently lead to lower fuel savings.

However, the car company can help improve this situation with a campaign driving directions using softer feet, but so far, no public agency to conduct such a campaign. Ford, GM, Chrysler, Hyundai, VW, BMW, Mercedes-Benz and others are offering a turbocharged four-cylinder mid-size cars to replace V-6 engine.
