  • Corvette Fuel Injection &amp; Electronic Engine Control: 1982 through 2001
    Corvette Fuel Injection & Electronic Engine Control: 1982 through 2001

    The engine is the heart of the Corvette and the heart of the Corvette engine is its electronic management system. Corvette Fuel Injection Electronic Engine Control is the book that explains that system. Chuck Probst, author of the authoritative Bentley books on Bosch and Ford fuel injection systems, has worked with GM and aftermarket engineers, trainers, and technicians to bring the same sort of inside information to an authoritative understanding of Corvette engine controls. The comprehensive troubleshooting tips and service procedures presented here are a great aid in mastering Corvette engine control systems. The book begins with a survey of the different fuel injection systems used in these cars: Throttle Body Injection (TBI), Multiport Fuel Injection (MFI), and Sequential Fuel Injection (SFI). Probst covers the reasons behind J1930 terminology (electrical/electronic systems diagnostic terms, definitions, abbreviations and acronyms) and the engine management concept of Open Loop and Closed Loop Operation. In addition, oxygen sensor and heated oxygen sensor operation, traction control, Exhaust Gas Recirculation (EGR), Air Injection (AIR), catalytic converters, evaporative controls, octane and fuel volatility are among the many thoroughly covered topics. Probst's treatment of On-Board Diagnostics (OBD and OBD II) involves topics such as misfire detection, crankshaft position sensor operation, Mass Air Flow (MAF) sensor design, Electronic Spark Control (ESC), and Central Processing Unit (CPU). No other book comes close in providing this much detailed, proven information, with 380 pages including 112 pages of model-specific wiring diagrams, trouble codes, and test specifications along with hundreds of photos and illustrations.

  • Modeling of a Liquid Phase LPG Fuel Injection System: Development, Modeling, and Experimentation
    Modeling of a Liquid Phase LPG Fuel Injection System: Development, Modeling, and Experimentation

    Liquid phase Liquid Petroleum Gas (LPG) is a developing alternative fuel system for engines which can provide the emission benefits of LPG and the power of a gasoline engine. LPG is traditionally used in the gas phase, but has limited power and emission benefits when used this way. Modeling the fuel system is a necessary method to predict and analyze the state of the fuel to ensure the fuel is in the proper phase during fuel injection. LPG fuel used in the liquid phase is much more sensitive to vapourization than typical liquid fuels, such as ethanol, gasoline, or diesel. Previous fuel system models using isothermal assumptions are unsuitable because of this. New dynamic and steady state models were developed using thermodynamic fluids instead. The new models predict both the thermal and pressure behavior of liquid phase LPG fuel systems. Separate model components were constructed for each component in the fuel system to allow them to be used as design tools. A series of experiments were conducted to verify the accuracy of the models and to investigate the causes of different fuel pressure fluctuations. The work presented was conduced as a research project at Dalhousie University.
