Combustion System Development
The main focus of Hiltner Combustion Systems is collaboration with clients to bring new internal combustion engine systems to market and improve those already in production. This goal is realized through a combination of engine testing, literature review, cycle simulation, analysis of test and simulation results, implementation of advanced controls, development of new concepts, and application of a fundamental understanding of combustion physics, chemistry, and thermodynamics to modern engine systems.
Control System Development
Increasingly sophisticated
combustion systems, offering higher BMEP and thermal efficiency, inevitably
call for improved engine control systems. This is particularly true for
highly charged, lean burn, spark ignited engines. Hiltner Combustion
Systems works directly with engine manufactures to develop and deploy new
control algorithms, hardware and software for both steady state and
transient engine operation. Our system level approach includes the
development and use of modern simulation tools, as well as the utilization
of rapid prototyping hardware for model and algorithm validation.
Simulation Tools
Despite the availability of several off-the-shelf engine system
simulation packages, new concepts and special applications often call for
custom simulation tools. Hiltner Combustion Systems works directly with companies in the engine industry to develop simulation and other computational tools tailored to their specific needs. Completing these projects on budget, on time, with constant input from end users, and with an eye towards future modification makes for useful and powerful tools that allow development engineers to optimize their future products.
Education and Training
A training class from Hiltner Combustion Systems can quickly make new hires and recent transfers productive team members. Class materials provide a long term reference and give employees new insights that lead to innovative thinking. Rather than a standardized class, Hiltner Combustion Systems will
work with your company to develop a course geared directly to your needs,
while stressing the practical application of engine thermodynamics, chemistry, and controls in your market.
New Concepts
Hiltner Combustion Systems can both help generate new concepts for specific engine applications and evaluate ideas generated elsewhere. In terms of new concept evaluation, HCS can determine in a short period of time the practical feasibility of an idea as well as its thermodynamic advantages or limitations. For concepts that show promise; simulation, prototype development and testing can be carried out in an open and innovative environment. If your company is looking for new solutions to the constantly evolving demands of the engine market, Hiltner Combustion System can assist you with our vast experience in this area.
Test Cell Design
While many companies offer test cell set-up and commissioning services, most offer prepackaged solutions
intended primarily for a given application. Hiltner Combustion Systems has worked with a number of industrial partners and universities to bring on line cost effective test cell systems aimed at particular applications. Previous work has included large single cylinder test cells, optical diagnostics, specialized emissions measurement systems, and non-traditional engine systems. Employing HCS provides a cost effective and flexible way to upgrade older facilities or handle unique testing challenges.
