to reach scalable volume deliveries as natural gas markets mature and
"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
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
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
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

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.
