In more detail, the truly revolutionary steps in engine construction were the mass introduction of turbocharging into production motors, the direct fuel injection system and, of course, electronic management systems.
More often than not, manufacturers act with caution: they take an engine that has been proven for years and decades and boost it with turbocharging and direct injection. Hyundai, for example, began installing direct injection first, then turbocharged.
For the EcoBoost engine every drop of fuel is expensive. So expensive that it reduces fuel consumption, significantly reducing CO2 emissions to 99 g/km. Detailed information on fuel consumption and CO2 emissions can be found on the respective vehicle pages. It has an outstanding performance is achieved thanks to its direct injection system. The exact amount of fuel at high pressure is injected directly into the combustion chamber. This innovative and efficient way of using fuel means that these motors are able to run on a depleted fuel-air mixture when the minimum amount of fuel is used when the vehicle is moving at cruising speed.
Each EcoBoost has turbochargers to produce power far beyond the motor volume. The turbochargers are unwinded with exhaust fumes that are not normally used, and at high pressure they pump air into the engine, resulting in a significant increase in power. Among other things, the turbine provides a wide range of torque.
As a result, EcoBoosts are better suited to public roads and require fewer gear changes. Variable timing allows high torque to be maintained even at low speeds and provides maximum power. Simply put, you always have an immediate response and a stock of injectivity needed when accelerating, for example to overtake a truck.
Is 3.5 or 5.0 EcoBoost better?
If we are talking about 3.5 ecoboost vs 5.0 reliability, the latter one might appear more reliable just due to a tiny incident when 22 cars came with incorrectly machined cylinder heads. However, it was the case only with those 22 vehicles and no more cars were affected. At the same time, the 3.5 F-150 is considered to be more fuel efficient.
As for the 5.0 vs 3.5. EcoBoost MPG, The former is 18 mpg combined (16 city, 22 hwy) and the latter is 19 mpg combined (17 city, 23 hwy).
Is V6 EcoBoost better than V8?
The general essence of EcoBoost is direct fuel injection, i.e. the nozzle is located directly in the combustion chamber, where mixing takes place. The obvious advantage is that the fuel has minimal contact with surfaces, less film loss equals economy. The second plus is the modes of operation, the mixture can be formed in the most “accurate” proportions: it can operate either on ultra-poor mixtures or on optimally rich ones (the mixture is rich, but the surplus does not fly into the pipe, almost). In order for the mixture to take place, a high fuel pressure is needed, otherwise it will be “blown” by the pressure in the cylinder, as well as a piston with a special notch.
Accordingly, as in diesel engines, it has a high pressure fuel pump and pistons have an interesting shape. There is also a turbine, which provides a good filling of the cylinders, and direct injection allows you to effectively fight against detonation, due to layer-by-layer injection, first fuel is injected at the rate of inlet (mixture of ultra-poor), second injection at the rate of compression, the mixture becomes rich, this process allows you to effectively cool the cylinders in the load conditions.
The system is very intelligent, it can regulate the modes of mixture formation, it has two phase-shifters, a turbine, many sensors.
Both V6 and V8 are considered highly reliable and efficient, however the former produces more torque and has a larger towing capacity (12.000 lbs). Whereas V8 is known for giving more horsepower (395 HP).
Is EcoBoost a good engine?
EcoBoost is the marketing name of the family of direct injection and turbocharged petrol engines. According to the manufacturer, the units provide 30% better efficiency, reduced by 15% greenhouse gas emissions.
The main characteristics EcoBoost is known for are its size and economical ability. At the same time, the units provide power not typical for engines of such volumes. At the same time, high torque is achieved over virtually the entire speed range. Thanks to this, vehicles equipped with EcoBoost, are more adapted to different road conditions (especially to traffic on public roads), demonstrate an immediate response to the accelerator pedal, provide the necessary reserve for performing complex maneuvers (such as overtaking at high speed).
The main components that made it possible to achieve a unique combination of steel characteristics:
- a direct fuel injection system with precise metering
- new turbochargers
- controlled gas distribution phases
The manufacturer sees EcoBoost technology as less expensive and more versatile, providing a real alternative to the development or expansion of electric, hybrid and new diesel engines.
How good is the 3.5 EcoBoost?
As for 3.5 EcoBoost reliability, this motor is considered to be highly reliable and can run for thousands of miles without overhaul and breakdown. Its maximum power is 365 HP. The type of this motor is V-shaped with 6 cylinders. The engine also has double turbocharging.
