- A combination of direct fuel injection and turbocharging is the key to EcoBoost’s small engine fuel efficiency and big engine power. Twin independent variable camshaft timing (Ti-VCT) completes the picture.
- EcoBoost engines can reduce fuel consumption by up to 20% and help reduce CO2 emissions.
- Every drop of fuel is burnt by injecting a highly pressurised, precise amount of fuel directly into the combustion chamber of each cylinder in the engine. An electronic control system varies the timing and intensity of each injection to match the engine’s operating conditions. This improves fuel efficiency and delivers smoother performance.
Direct fuel injection
- Turbocharging uses the engine’s exhaust gases, which would otherwise be wasted, to push more highly compressed air into the engine. The more air in the combustion chamber, the more power you get out.
- Together with variable cam timing, it generates high torque low in the rev range (rpm) and maintains peak power over a wide range. This gives immediate responsive power when you accelerate.
- Cool air intake valves and hot air exhaust valves simultaneously overlap so more air flows through the combustion chambers for a very cool, dense charge that helps build torque in the engine. The extra air flow also helps the turbocharger’s turbine to run faster so engine output builds very quickly, virtually eliminating any ‘turbo lag’.
- The traditional fast-rotating balance shaft used to offset shaking forces for greater refinement adds weight, cost and uses a lot of fuel. So we took it out of our 1.0L EcoBoost engine. Instead, we deliberately unbalanced the flywheel and front pulley in a way that combines mathematically with piston movements to offset shaking forces for a highly refined performance.
- Currently, there are 125 patents across all EcoBoost engines.

A street-legal Formula Ford racing car with a specially-tuned 1.0L EcoBoost has clocked the 11th fastest time at Germany’s legendary Nurburgring circuit. Its impressive time of just 7’22” beat the likes of the Lamborghini Aventador and Ferrari Enzo.
