Westport Unveils Next Generation High Pressure Direct Injection (Westport™ 
HPDI 2.0) System 
~New Release Provides Unparalleled Performance, Fuel Economy and Value~ 
VANCOUVER, Dec. 10, 2013 /CNW/ - Westport Innovations Inc. (TSX:WPT / 
NASDAQ:WPRT), engineering the world's most advanced natural gas engines and 
vehicles, today unveiled its next generation of high pressure direct injection 
technology platform dubbed "Westport™ HPDI 2.0." This new generation of the 
class-leading natural gas technology will provide global vehicle and engine 
original equipment manufacturers (OEMs) with a vertically integrated natural 
gas solution with breakthrough price, performance, and fuel economy. 
Developed to the most rigorous OEM quality standards, Westport™ HPDI 2.0 
system components will be manufactured in state-of-the-art, high-quality 
facilities, offer ready integration into OEM operations globally, and provide 
an attractive way to reach scalable volume deliveries as natural gas markets 
mature and grow. 
"Where performance, emissions and efficiency matter, HPDI 2.0 offers benefits 
that will be irresistible to fleet customers shifting to natural gas in their 
operations," said David Demers, CEO of Westport. "As the potential for 
natural gas is now apparent in all global vehicle and off-road markets, HPDI 
2.0 will allow OEMs to introduce high performance, fully integrated products 
that match state of the art diesel performance, but can be produced without 
expensive and challenging investments in facilities, product development, and 
testing." 
Westport is now working with seven OEM applications with engine sizes ranging 
from trucks to trains at various stages of development with the goal of 
vertically integrated Westport™ HPDI 2.0 OEM product lines. 
Background on Westport™ HPDI 
Westport™ HPDI 2.0 is the only natural gas technology capable of delivering 
performance and fuel economy equivalent to that of current high performance 
diesel-fueled engines, but with diesel substitution of over 90%. This 
combination of high performance and high efficiency is critical for heavy-duty 
engines in demanding commercial applications. 
Diesel engines have dominated commercial vehicle and heavy-duty off-road 
applications for decades, despite higher initial costs for diesel engines 
compared to gasoline engines, and the recent volatility and higher prices for 
diesel fuel. Energy efficiency, engine durability, high torque, low 
maintenance, and industry familiarity with the diesel engine mean that overall 
life-cycle cost of operation have kept the engine a mainstay in commercial 
vehicles. 
However, Westport™ HPDI will allow diesel customers to switch to natural 
gas, which is much cheaper than diesel fuel in most parts of the world, 
without sacrificing performance or energy efficiency. Engines incorporating 
Westport™ HPDI 2.0 technology are engineered to be as similar to 
diesel-fueled versions as possible, minimizing capital investment and 
operational changes in the field. 
Higher energy efficiency simply means less fuel burned, resulting in more 
money that the operator can save, and lower greenhouse gas emissions. The 
compression ratio of an engine with Westport™ HPDI is the same as the diesel 
engine on which it is based, which results in fewer changes to engine 
components and preservation of the fuel economy benefits associated with high 
compression. 
Westport's proprietary, patented HPDI technology utilizes the same Diesel 
thermodynamic cycle used by diesel fuel. This Diesel cycle is inherently more 
efficient than the Otto thermodynamic cycle used by spark ignited (SI) 
gasoline and natural gas engines.Aside from the increase in efficiency, 
typical Diesel cycle engines—including engines with Westport™ HPDI—do 
not use a throttle to control the air-fuel ratio, as the gas directly injected 
into the combustion chamber at the end of the compression stroke can burn over 
a wide range of air fuel ratios.Current SI engines have to use a throttle 
to meter the air to control the air/fuel mixture resulting in more constricted 
air flow into the engine and reduced fuel efficiency. 
Most current natural gas engines used in mobile applications require up to 30% 
reduction in compression ratio and 15% to 20% reduction in peak torque output 
to avoid the risk of engine-damaging knock, which reduces fuel economy and 
performance. Late-cycle direct injection of fuel—a principle fundamental to 
the Westport™ HPDI architecture—is the only combustion approach that 
eliminates the danger of engine knocking. In SI gasoline and natural gas 
engines, air and fuel are pre-mixed before entering the combustion chamber. 
Knock can occur when combustion of the air/fuel mixture in the cylinder starts 
off correctly in response to ignition by the spark plug, but one or more 
pockets of air/fuel mixture explode outside the envelope of the normal 
combustion front. SI engines that run on natural gas need a lower compression 
ratio to reduce the chance of engine knock. The compression ratio must be low 
enough to ensure combustion events do not begin until after compression is 
complete and the spark plug is fired. Inevitably, lower energy efficiency is 
the result, which means more fuel burned to achieve the same level of work. 
Westport™ HPDI uses natural gas as the primary fuel along with a small 
amount of diesel as an ignition source. The two fuels are not pre-mixed with 
the intake air before they enter the combustion chamber so there is no risk of 
engine knock and therefore no need to lower the compression ratio and peak 
torque output.As compared to diesel fuel, directly injected natural gas 
burns with a lower adiabatic flame temperature and has a low propensity to the 
formation of carbon particles and therefore offers inherent nitrous oxide 
(NOx) and particulate matter (PM) emissions benefits that provide more product 
engineering flexibility to allow powertrain designers to increase potential 
performance and customer value.

Equally important to vehicle performance and operability, fuel storage and 
delivery is often ignored or treated as an afterthought when converting 
engines to use natural gas. Westport vehicles and technology have logged 
millions of miles over the past few years, and it is clear that high 
performance natural gas engines will need sophisticated fuel delivery and 
storage systems to fully exploit the potential of natural gas as a primary 
fuel. 
HPDI 2.0 continues the evolution of Westport natural gas storage and delivery 
systems with a new generation of proprietary fuel tank, fuel pump, and system 
controls that can match the vehicle range, performance, and driveability of 
diesel whether the vehicle is a long-haul truck, a locomotive, or a ship. 
Westport™ HPDI 2.0 is a complete architecture, offering OEMs flexibility to 
differentiate their natural gas product lines easily while also maintaining 
maximum commonality with their conventional diesel fueled products. We think 
it's the future of natural gas. With the development of Westport™ HPDI 2.0 
we have captured many significant new proprietary technologies that will 
extend the reach of our HPDI patent portfolio for the next 20 years. HPDI 2.0 
is protected by global patents. Westport has filed 42 patent applications for 
new inventions related to Westport™ HPDI since 2007. Westport remains 
committed to continuous innovation and improvement. 
Westport™ HPDI 2.0 Features 
Exclusive Westport(™ )HPDI 2.0 systems features include: 


    --  Optimization of combustion and higher efficiency: Provides
        improved fuel economy, which results in faster payback compared
        with Westport's first generation HPDI product and compared to
        spark-ignited natural gas engines. Westport™ HPDI engine
        efficiency under highway operations is approximately 44%
        compared with spark ignited natural gas engines at
        approximately 37%. This means approximately 15% to 20% fuel
        economy improvement compared to spark ignited natural gas
        engines under typical operating conditions.
    --  Proprietary HPDI 2.0 dual common rail fuel injector: Designed
        for adaptability and multiple OEM engines ranging from 10 liter
        to 100-liter displacement (typically, over 50 kW per cylinder
        output) featuring higher performance and controllability,
        greater reliability, and longer life, and much lower cost.
        Unique concentric dual-needle design with electro-hydraulic
        actuation and control.
    --  Proprietary on-engine gas fuel conditioning module: Designed
        for more precise pressure control for even lower engine
        emissions and better fuel economy. New sealing designed for
        longer durability. Smaller size for ease of packaging on the
        engine.
    --  Redesigned electronic control systems: Allows full integration
        with existing engine and vehicle controls.
    --  Improved components: Completely reorganized supply chain allows
        for reduced production costs and increased scalability for
        manufacturing alongside existing diesel-based components for
        multiple OEMs. For example, the new gas control module (GCM)
        has been reduced in cost by approximately 60%.
    --  System performance: High transient performance with integrated
        fuel storage and delivery systems that ensure proper fuel flow
        under all driving conditions, improving performance,
        driveability, and safety at lower cost.
    --  Got brakes? By using the same high compression ratio as diesel
        engines, Westport™ HPDI engines deliver engine braking
        power equivalent to that of diesel engines which is critical in
        many trucking applications.  The reduced compression ratio used
        in SI engines results in an approximately equivalent reduction
        in engine braking performance.
    --  Compatibility: Westport™ HPDI 2.0 is designed for
        complete compatibility with state of the art commercial
        vehicles today. For example, by injecting fuel precisely into
        each cylinder, HPDI provides the same responsiveness and fast
        torque achievement as diesel engines, resulting in benefits
        such as an easier ability to be matched to automated manual
        transmissions (AMT).
    --  Improved emissions profile: Westport™ HPDI 2.0 is
        designed to meet the latest in stringent emission regulations
        including Euro VI and EPA 2014 and is the only natural gas
        technology that can control methane emissions in-cylinder
        avoiding costly methane aftertreatment. As an added benefit,
        the significant increase in efficiency of HPDI over traditional
        SI engines affords Westport™ HPDI 2.0 dramatically lower
        greenhouse gas (GHG) emissions than conventional natural gas or
        diesel engines.
    --  Compliance and certification: In addition to the emissions
        certification for HPDI 2.0 engines, OEM's vehicles built with
        Westport™ HPDI 2.0 technology will comply with applicable
        safety standards in North America—such as relevant
        Federal Motor Vehicle Safety Standards (FMVSS), National Fire
        Protection Association (NFPA), and Society of Automotive
        Engineers (SAE) standards—and their equivalents in Europe
        such as Regulation No. 110 of the Economic Commission for
        Europe of the United Nations (UN/ECE).
    --  Heat rejection: while the higher compression of Westport™
        HPDI 2.0 engines provide the heat necessary to auto-ignite
        their fuel, combustion in the Diesel thermodynamic cycle is
        more efficient, with more power and less heat produced than
        with the Otto thermodynamic cycle prevalent in SI engines.  
        Westport™ HPDI engines operate at similar engine
        temperatures as diesel engines, reducing cooling challenges and
        reducing stress related reliability and durability challenges
        for other SI-based engine systems including turbochargers and
        exhaust treatment systems.
    --  Proprietary liquefied natural gas (LNG) tanks: Westport™
        HPDI 2.0 LNG tank solutions range from 70 to 150 US gallons and
        up to 20,000 gallons for off road applications.  The new tank
        configurations feature lower costs, high-quality testing and
        validation, and new designs for structures enabling several
        vehicle-mounting configurations including behind-the-cab gantry
        and frame-rail packages to simplify vehicle design and
        production. Westport has invested over $1 million in HPDI 2.0
        LNG tank testing and validation under extreme conditions to
        simulate the toughest environments for natural gas products.
    --  New proprietary intelligent LNG fuel pump: Our redesigned
        cryogenic fuel pump is hydraulically driven and uses a
        single-stage, slow reciprocating architecture. This provides
        significantly lower cost, higher performance, and longer life
        and allows the use of fuel stations that deliver cold LNG,
        which improves vehicle range, and reduces station cost. The
        HPDI 2.0 fuel system is rated for delivering warm high pressure
        gas to truck engines with ratings up to 600 hp and to large
        off-highway engines up to 4,500 hp. Unlike traditional LNG
        systems, the full maximum flow rate is sustainable from the
        moment the truck is refilled to the moment the tank is empty.
        Because the pump is integrated into the tank module, there is
        no pump cool down time.
    --  CNG capability:  Every natural gas engine burns compressed
        natural gas (CNG). Ultimately, the customer will decide which
        form of natural gas they wish to carry—either high
        pressure CNG or cold cryogenic LNG—based on a number of
        variables including but not limited to: weight of the load;
        weight of the fuel storage system; range required by the
        vehicle; and availability of CNG and LNG. The HPDI 2.0 system
        is architected to be compatible with LNG and CNG allowing the
        market to decide which storage method it prefers. Given the
        energy density of LNG compared with CNG, and Westport™
        HPDI's ability to haul heavier loads over longer distances as
        compared with traditional natural gas engines, in most cases we
        expect HPDI applications will select LNG fuel storage.

Overall, Westport™ HPDI 2.0 will provide a compelling combination of 
diesel-like power, torque, fuel efficiency, and engine braking performance in 
a natural gas engine—making it ideal for almost all commercial freight 
applications.

Migration Path for HPDI 1.0

Westport first generation HPDI systems have been delivered on more than 1,200 
Peterbilt and Kenworth trucks since its first wide-scale introduction in 2010. 
As noted in previous news releases and customer communication, Westport is 
committed to the continuation of its class-leading support for all our 
existing customers with the first generation of HPDI.

In partnership with Peterbilt and Kenworth dealers, Westport will be able to 
offer compatible next generation system features to our existing customers, as 
some HPDI 2.0 components are applicable to first generation HPDI. The benefits 
are expected to be reduced costs, improved components, and increased 
durability and performance. For customers, further information is available 
from your Westport representative.

Pricing

Westport HPDI 2.0 has been designed for simplicity, performance and a 
reduction in overall system costs. For the first time, Westport expects OEM 
Westport™ HPDI vehicles to be competitively priced with SI-based systems. 
The increased performance in torque and related power in Westport™ HPDI, 
combined with the best fuel economy and related emissions profile and the 
fully integrated engineered Westport™ HPDI 2.0 products will give OEMs and 
their customers the ultimate natural gas engine and vehicle performance and 
reliability, and strong economic value particularly in high fuel use 
applications.

Westport™ HPDI 2.0 is in development now with a number of global OEMs and 
Westport anticipates first availability of customer products in late 2014 and 
2015.

Market Opportunity for HPDI Natural Gas Vehicles

According to the International Energy Agency, world oil demand for commercial 
road freight and other heavy-duty transport modes, including rail, totalled 
approximately 273 billion gallons in 2012. The U.S. Energy Information 
Association predicts that the price of LNG will remain below the price of 
petroleum diesel for at least the next two decades and be approximately 33% 
below in 2035, with a gallon of diesel expected to be selling for $4.55 
compared to a diesel gallon equivalent of LNG at $3.05. At these rates, if 
the world changes the way it moves goods by shifting to natural gas, these 
transport modes could save over $400 billion per year. The market for 
natural gas in transportation in China is bourgeoning. According to the 
International Energy Agency, natural gas demand in China's commercial road 
transport sector will reach around three times higher than today's levels by 
2035.
