  5. 5. 5Introduction• Ecoboost is a new generation of Ford petrol engines, which deliver outstanding fuel economy, together with great fun to drive and refinement in line with the Ford brand DNA.• Ecoboost offers customers a genuine alternative between conventional naturally aspirated petrol engines, and very efficient, but increasingly complex and expensive Diesels.• The new 1.0l engine is the fourth in the Ecoboost series, which started with the 3.5 V6, launched in North America in 2009, continued with the 2.0 and 1.6 in 2010, and extends further with the 1.0 launch in 2012.

  7. 7. 7Ecoboost Family Philosophy• All Ecoboost engines feature significant downsizing vs. naturally aspirated derivatives, as a means to enhance fuel economy. Downsizing offers numerous advantages: • Lower mass: better performance, reduced real world consumption, improved dynamics, smaller tyres, less energy consumed by PAS. • Less cylinders: lower cost, keeps technology accessible for consumer • Reduced friction: fewer cylinders, bearings, less lubrication • Significantly better warmup for both good fuel economy and rapid cabin heating.• Key engineering challenge is to maintain, or enhance, performance and refinement, while delivering the fuel economy advantages of downsizing, as customers have shown that they are reluctant to compromise.
  8. 8. 8European Diesel share vs. performance.• Diesel sales growth driven by performance gains, not FE advantage. 60 380 50 330 Peak Torque [Nm] Diesel Share [%] 40 280 30 230 20 180 10 130 Diesel share (%) Peak Torque [Nm] 0 80 88 89 90 91 92 93 94 95 96 97 98 99 00 01 02 03 04 Year
  9. 9. 9Customer Performance Expectations• Traditional petrol engine customers enjoy smooth, free-revving nature and peak power figure high in RPM range.• Diesel customers like high peak torque from low RPM, and relaxed cruising.• Ecoboost engines offer both of these attributes, and careful matching to the vehicle by means of gearing, means that Ecoboost engines appeal to wide variety of customers, driving style and environments.

  12. 12. 12Ecoboost Technology• Ecoboost engines feature three key enabling technologies:• Turbocharging – allows much greater torque & power from smaller engine• Direct injection – improves combustion efficiency• Variable camshaft timing – increases bottom end torque, mid range efficiency and peak power capability.
  13. 13. 13 Ecoboost: Three Key Elements Working as a System Turbocharging - 50% engine size reduction for same power - Proven, reliable, cost effective technology - Matched for low speed responseDirect Injection Twin VCT- Charge cooling for improved efficiency - Scavenging for low RPM response- Higher knock limit/more torque at low RPM - Improved efficiency and stability at part load- Enables scavenging action - Higher peak output
  14. 14. 14Ecoboost Technology - Turbocharging• Ecoboost focus is on responsiveness and low speed torque rather than very high peak power figures.• Torque at 1500 RPM, and time for torque to increase to maximum output are key metrics.• Achieved by utilising very small, low inertia turbochargers, capable of running at very high speeds, up to 248,000 RPM on 1.0L• Low inertia turbos greatly reduce “lag” in response when throttle is opened from low RPM, a traditional problem with turbocharged engines
  15. 15. 15Ecoboost Technology – Direct Injection• Fuel is injected directly into combustion chamber via high pressure solenoid injectors, with 6 holes giving precise fuel targeting and mixing.• High injection pressures (up to 150 Bar) give excellent atomisation and mixing.• Multiple injections per stroke are used at some operating points to optimise fuel economy, emissions and stability• Evaporation of fuel in cylinder cools mixture before combustion, reducing tendency to “knock”.• Allows higher Compression Ratio than normal for turbo engines, improving part-load fuel efficiency.• Eliminates transfer of fuel mixture from inlet to exhaust during valve overlap, improving fuel consumption and reducing exhaust emissions.
  16. 16. 16Ecoboost Technology – Variable Cam Timing• Variable cam timing on both intake and exhaust allows great flexibility to optimise engine efficiency under all conditions, e.g. • Moderate overlap at full load to improve breathing and output with reduced boost level • Low overlap at idle for stability • Late exhaust valve opening at part load for fuel efficiency• Greatest benefit is for low speed torque and responsiveness, where valve overlap can be increased to allow scavenging effect.
  17. 17. 17Scavenging Effect• At low speed & high load, • Intake Manifold Pressure > Exhaust Backduring the valve overlap period, Pressure (due to boost)it is possible for the intakemanifold pressure to exceed theinstantaneous exhaust backpressure due to turbo-charging.• Under these circumstances,“scavenged” air will flow directlyfrom the intake into the exhaust.• Scavenging flushes residualgases from cylinder, increasingmass of following charge, andcooling gas to reduce tendencyto knock. It also increasesturbo mass flow, helping spool-up turbo.

  19. 19. 191.0L 3-Cyl Ecoboost Technology Highlights • Extremely compact block design, enabled by use of cast iron ilo aluminium, small bore, long stroke geometry (71.9mm x 82.0mm), and 6mm siamesed bore design. Total block length 286.2mm. • Aluminium cylinder head with integrated exhaust manifold (IEM). 4V layout with central injector & compact spark plug. 10.0:1 CR • Rapid warmup due to small iron block, IEM, and split cooling system with horizontally split head and controlled block/head circuits. • ECU controlled variable displacement oil pump and low loss lubrication system • New Continental turbocharger with vacuum actuated wastegate, allowing opening when off boost to reduce backpressure. • Ultra-low friction design, with offset crank, coated pistons & tappets, low tension rings, low friction crank seals. • Cam drive via unique belt-in-oil design, giving full life belt, with advantages of quietness & lightness vs. chain.
