The system supports angle and time-based measurement and uses highly sophisticated algorithms for online or offline mathematics and statistics to calculate heat release and other thermodynamic parameters. In addition to combustion analysis , the same system can be also used for power analysis. The combustion analyzer system can be used on all types of vehicles with internal combustion engines, such as passenger cars, trucks, ship, motorcycle, power-saw, etc.
For testing under the real conditions, the combustion analyzer is perfectly suited for in-car testing applications. On the engine testbed , a combustion analyzer is a standard tool to calculate and visualize relevant physical parameters from the internal combustion engine and to monitor and protect the unit under the test.
Different communication protocols to the control room are supported via Ethernet or RS interfaces - e. Channels not needed, can simply be disabled with a click of a button instead of having to remove them from the list. Multiple combustions analyzers can run in parallel and it is possible to select which one is the reference for the cycle count for the TestBed. Instead of storing and triggering based on cycles only, the time interval can be defined in seconds.
This makes the testbed perfect for electric and hybrid motor testing or NVH applications. Extensive online or offline mathematical computation will allow you to:. The award-winning Dewesoft X data acquisition software offers an easy and very intuitive configuration process. Simply select the engine type with the number of cylinders and its geometrical parameters and you are ready to measure combustion.
When the configuration is complete you can select your desired calculation outputs. The online heat release calculates the energy for each cycle and its related parameters.
All these values are based on the heat release algorithm. The fuel-air charge is meant to be ignited by the spark plug only, and at a precise point in the piston's stroke. Combustion noise is becoming increasingly important as a major noise source in internal combustion engines and thus becoming an important decision parameter of buying combustion engines. The design and development of modern internal combustion engines are marked by a reduction in exhaust gas emissions and an increase in specific power and torque.
Correspondingly, combustion noise excitation, and fuel consumption also have to be reduced. The combustion noise must be calculated in the time domain. The measured value is scaled from the Bar unit to the Pascal unit. This is then followed by the U-filter, which simulates the transfer function of the engine 1. Calculated values may be used for optimization or other automated procedures. The raw data from sensors will always be stored and stayed intact. This allows for any offline calculations to be done at any time.
This allows delaying CPU intense calculations until after the measurement has finished.

Engine Combustion: Pressure Measurement and Analysis Abstract: Engine combustion pressure analysis is a fundamental measurement technique applied universally in the research and development of reciprocating combustion engines. As combustion pressure measurement systems have become almost standard equipment in engine test environments, technicians and engineers need to have a solid understanding of this technique and the associated equipment. This book provides practical information on measuring, analyzing, and qualifying combustion data, as well as details on hardware and software requirements and system components. Describing the principles of a successful combustion measurement process, the book will enable technicians and engineers to efficiently generate the required data to complete their development tasks.
Accurate measurements of cylinder pressure and crank angle as well as intake- and exhaust-gas pressure are absolutely crucial factors when developing combustion engines. Kistler offers a comprehensive portfolio of combustion analysis technology for a variety of applications, ranging from water-cooled and uncooled piezoelectric cylinder pressure sensors to measuring spark plugs and glow plug adapters with integrated miniature pressure sensors. Piezoresistive absolute pressure sensors for gas exchange and injection pressure measurements with digital temperature compensation guarantee maximum precision. The high-performance products from Kistler also include the KiBox and SCP signal conditioning systems, with a wide range of interfaces, measurement results are easily transmitted to other instruments. Measuring systems from Kistler to evaluate and optimize combustion engine parameters such as power, efficiency and emissions. Contact us for further information.
Review of Sensing Methodologies for Estimation of Combustion Metrics
Libin Jia, Jeffrey D. Naber, Jason R. For reduction of engine-out emissions and improvement of fuel economy, closed-loop control of the combustion process has been explored and documented by many researchers.
This paper analyzes combustion chamber pressure data processing methods related to the number of cycles averaged, top dead center referencing and pressure referencing pegging. A total of consecutive engine cycles were measured in a four-cylinder diesel engine. The number of cycles that minimizes the influence of cycle-to-cycle oscillations depends on engine operating conditions and the parameters under analysis.
This paper analyses the uncertainty of pressure measurements in-cylinder and in injection pipe conducted during the studies of a compression ignition engine. Type A and type B evaluations were used to determine the uncertainties of the results. The results are presented for the engine running on diesel or bio-fuel and operating under full load conditions.
This book deals with in-cylinder pressure measurement and its post-processing for combustion quality analysis of conventional and advanced reciprocating engines. It offers insight into knocking and combustion stability analysis techniques and algorithms in SI, CI, and LTC engines, and places special emphasis on the digital signal processing of in-cylinder pressure signal for online and offline applications. The text gives a detailed description on sensors for combustion measurement, data acquisition, and methods for estimation of performance and combustion parameters. Provides a range of different models for estimating heat release and heat transfer for combustion quality analysis;.
