Ford is introducing 20 new engines and transmissions in China by
2015 in a comprehensive strategy to upgrade its entire powertrain
portfolio in the world's largest auto market. This upgrade aims to
support its aggressive plan to introduce 15 new vehicles to China by
2015.
Utilizing state-of-the-art technologies such as turbocharging,
direct injection, twin independent variable camshaft timing (Ti-VCT) and
six-speed transmissions, the upgraded powertrain portfolio will deliver
over 20% in fuel economy improvement to Ford's passenger vehicle fleet
in China by 2015 while reducing tailpipe carbon dioxide emissions by
20%.
Ford also announced that it will produce its latest all-new
1.0-litre EcoBoost engine, the smallest in the EcoBoost engine family,
in China to equip its vehicles produced and sold in the market.
"Ford is committed to be a fuel economy leader in every segment
that we compete by utilizing advanced powertrain technologies. These
technologies represent a core part of our near-term sustainability goals
in China," said Kumar Galhotra, vice president, Product Development,
Ford Asia Pacific and Africa.
"Earlier this year at the Shanghai Auto Show, Ford announced a plan
to introduce 15 new vehicles to China by 2015. All these new vehicles
will launch with the latest Ford-developed powertrains which will
improve fuel economy and lower carbon dioxide emissions, offering our
customers a more environment-friendly ride without compromising vehicle
performance."
Universal application of EcoBoost Engine
Ford holds more than 125 patents for its high-performance and
fuel-saving EcoBoost technology in the United States. EcoBoost, which
uses turbocharging and direct gasoline injection to boost engine output
and reduce emissions without sacrificing fuel economy, marks a major
milestone in the Ford strategy to deliver technologically advanced,
high-output, smaller-displacement powertrains.
The integration of three advanced technologies – turbocharging,
direct injection and Ti-VCT – into the EcoBoost powertrain delivers
significant customer benefits:
- Optimized engine efficiency: delivers up to a 20% improvement in fuel economy, 15% reduction in carbon dioxide emissions compared with conventional gasoline engine
- Superior driving performance: strong low-end torque and responsive performance across the full rev range
- Advantages of small displacement: large-engine performance, but with the size, weight and fuel economy of a much smaller unit
A key advantage of the Ford EcoBoost approach is the ability to
downsize engine capacity, so that larger naturally-aspirated engines can
be replaced by much smaller units without sacrificing power output.
The performance boost offered by turbocharging typically results in
a 50% increase in torque, so there is a significant opportunity to
downsize capacity while still providing a potential performance benefit.
The advantages of downsizing include improved efficiency through
reduced internal friction, lower pumping losses, and lighter weight –
which also makes the engine warm up more quickly. This helps to ensure
that the real-world fuel economy benefits of Ford EcoBoost engines are
delivered in all driving conditions, including both city and highway
driving.
The global EcoBoost engine family is the cornerstone of Ford’s
near-term sustainability plan to deliver high-volume, affordable,
fuel-efficient vehicles that customers around the world want and value.
By 2013, the company plans globally to produce 1.5 million EcoBoost
engines annually. Also, by 2013, nearly 80 percent of Ford’s global
nameplates will be available with EcoBoost.
Ford launched the 2.0L EcoBoost-equipped Mondeo-Zhisheng in China
earlier this year.. According to the certification issued by the
Ministry of Industry and Information Technology (MIIT), the vehicle's
7.9L/100km fuel consumption is one of the best in the segment.
Ford will offer the 1.0L EcoBoost engine on small-to-medium
vehicles, and the engine will be built in China, with a plan to
introduce more EcoBoost engines based on market demand. By 2015,
EcoBoost engines will be available on most Ford branded passenger cars
in China.
Upgrading conventional engines
Ford will introduce an advanced non-turbocharged engine in China
that combines the technology of gasoline direct injection technology
(GDI) and Ti-VCT to offer vehicles with more dynamic performance and
better fuel efficiency.
At the heart of this is a high-pressure direct injection system
which injects fuel into each cylinder in small, precise amounts at a
pressure of up to 200 bar – the droplet size is typically smaller than
0.02mm, one-fifth the width of human hair. Compared to conventional fuel
injection, direct injection produces a cooler, denser charge,
delivering improved fuel economy and performance.
The system could inject highly pressurized fuel into the combustion
chamber of each cylinder rather than traditional mixing with the
incoming air in the inlet port. Advantages include more precise delivery
of fuel for lower emissions, improved volumetric efficiency and
avoidance of knock for better performance and fuel efficiency.
The Ti-VCT technology allows extremely precise, variable control of
“valve overlap,” or the window of time in which both the intake and
exhaust valves in an engine are open at the same time. By adjusting
overlap continuously, an engine can operate at optimum settings for peak
fuel economy or peak power output as conditions demand. It could reach
up to a 7% improvement in peak power and a 5% improvement in low-speed
torque for better acceleration, passing and merging performance and up
to a 4.5% improvement in fuel economy. Ti-VCT also facilitates an
“internal EGR” effect, reducing NOx (a contributor to smog) and
hydrocarbon emissions throughout the engine’s operating range.
Six-speed transmissions for a smoother drive
As part of its powertrain upgrade, Ford plans to replace the
current four-speed automatic transmission with advanced six-speed
transmissions which will not only provide smoother gear shifts but also
improved fuel economy.
Leading the way is Ford’s innovative PowerShift six-speed automatic
transmission that combines the efficiency and driving dynamics of a
manual gearbox with the convenience of a conventional automatic
transmission. Unlike regular hydraulically operated automatic
transmissions, which use power-sapping torque converters, wet clutches
and pumps, the PowerShift automatic consists of two manual transmissions
(in the same case) working in parallel. The dual clutches engage and
disengage in a way that provides seamless delivery of torque to the
wheels, even during gear changes.
The transmission also features Hill Launch Assist that prevents the
vehicle from rolling back by maintaining enough brake pressure until
the engine delivers enough torque to move the vehicle up the hill
providing improved driver confidence, comfort and clutch robustness
Other than the PowerShift transmission, Ford also plans to
introduce a full range of six-speed transmissions to satisfy market
demand. Compared to the current four-speed automatic transmission, the
new six-speeds will deliver smoother gear shifts, seamless torque
delivery and superior fuel economy.
Expanding production capacity
In line with Ford’s strategy to overhaul its powertrain lineup in
China, most of these new powertrains will be manufactured in the country
for use in future vehicles. Currently, Ford’s joint venture in China,
Changan Ford Mazda Automobile Co., Ltd. (CFMA), is building a new engine
plant and a new transmission plant, with initial annual capacity of up
to 400,000 in each plant.
