Engine Calibration Methods and Tools

Source: FEV Modern engine developments are significantly impacted by overall efficiency. The goal is to optimize the trade-off between quality, timing and costs. Additionally, this situation is intensified by the distinct increase in the complexity of almost every area of modern diesel engine technology (Homogeneous Charge Compression Ignition, advanced injection strategy, hybrid, Selective Catalytic Reduction, NOx adsorber and decoupled governing). Furthermore, it is apparent that all phases of the development, starting from concept to SOP, are impacted. FEV supports the development process through the use of standardized methods for the appropriate tools, to further improve FEV’s high level status as a valuable and proven development partner in all areas of engine development. These tools have to be acquired and oriented directly by the needs of current and future complex diesel development. Consequently, original ideas that include integrated diesel engine knowledge and intelligent solutions are utilized by all of the technical departments of FEV’s diesel group. Flexibility and preparedness for future development requirements, which are the best basis to illustrate proven results and robust solutions of our customer’s goals, has led FEV to install and complete these standards, methods and tools through it’s own development department. All tools are tested and proven under real life operating conditions and finally integrated into FEV’s TOPexpert program. For more detailed information, please refer to Functions & Methods under TOPexpert tools. The integrated and tool-supported development will result in saving resources, time and expenses through the growth of off-line activities that enable high quality solutions by using a numerical solver. Engine Calibration Methods and Tools These tools will support the capabilities of engineering, but will never be a substitute for them. It is only through the appropriate integration of such tools to the development program that will lead to the intended quality and guarantee target achievements. The validation of tool-aided diesel engine development results in real boundary conditions and is necessary for providing proven solutions to our customers. FEV’s diesel group is working on appropriate next generation methods and tools to satisfy future, advanced diesel development goals for our clients.

Alternative fuels

Alternative fuels are derrived from resources other than petroleum. Some are produced domestically, reducing our dependence on imported oil, and some are derived from renewable sources. Often, they produce less pollution than gasoline or diesel. To promote alternative fuels, the Federal government offers tax incentives to consumers purchasing qualifying alternative fuel vehicles. E85 Pump Label Ethanol is produced domestically from corn and other crops and produces less greenhouse gas emissions than conventional fuels. Biodiesel Logo Biodiesel is derived from vegetable oils and animal fats. It usually produces less air pollutants than petroleum-based diesel. CNG Logo Natural gas is a fossil fuel that generates less air pollutants and greenhouse gases. CNG Logo Propane, also called liquefied petroleum gas (LPG), is a domestically abundant fossil fuel that generates less harmful air pollutants and greenhouse gases. DOE Hydrogen Program Logo Hydrogen can be produced domestically from fossil fuels (such as coal), nuclear power, or renewable resources, such as hydropower. Fuel cell vehicles powered by pure hydrogen emit no harmful air pollutants. http://www.fueleconomy.gov/feg/current.shtml

MOTEC engine management

MOTEC is one of engine management which is very convinient, friendly and easy set and reset. I have tried to tune my car using MOTEC engine management system version M800 couple months ago and the result is very impressive. I did some simulation using LOTUS simulation package to visualise the engine performance before connecting to new ECU. And finally set up to engine dyno ( eddy current typed) and compare with the simulation result, dyno test as well as production or OEM setting. I have some pictures to share with you all my experience with MOTEC engine management system.
