Internal Combustion Engine Efficiency

Written by an author who has devoted the past twenty-five years of his life to studying and designing shock wave engines, this unique book offers comprehensive coverage of the theory and practice of shock wave engine design. The only book treating the complete preliminary design of shock wave engines, it provides engineers with practical step-by-step guidelines applicable to the design and construction of small, lightweight, low-powered industrial turbines as well as high performance jet aircraft engines. In his discussions of the advantages and disadvantages of shock wave versus other types of combustion engines, Dr. Weber demonstrates how and why shock wave engines can be made to work more efficiently than conventional gas turbines. Among other things, he shows quantitatively why combustion temperatures can be significantly higher in shock wave engines than conventional gas turbines. He evaluates temperatures of moving parts in terms of combustion and engine inlet temperatures, and explores the effect of shock coalescence, expansion fan reflections and intersections on port sizes and locations. And throughout, real and imagined performance problems are posed and proven solutions given for shock wave engines - alone and in conjunction with conventional gas turbines or reciprocating internal combustion engines. Designed to function as a practical guide, Shock Wave Engine Design offers concise step-by-step design techniques in a readily usable format. Engineers will find precise, detailed directions on such essentials as how to size wave rotor blade lengths and heights and the correct rotor diameter for a specified power, and material selection for rotor and stator. And one entirechapter (Chapter 12) is devoted exclusively to a detailed example design for a 500 hp engine.

Chrysler Hemi engine - A Chrysler Hemi engine is one of three different internal combustion engine families from the Chrysler Corporation (or its successor, DaimlerChrysler) that are Hemi engines; in other words, they utilise a hemispherical combustion chamber. A hemispherical cylinder head allows the valves to be inline rather than side-by-side, which gives a straighter, simpler airflow path, allows large valves, and gives greater efficiency.

Internal combustion engine - The internal combustion engine is a heat engine in which combustion occurs in a confined space called a combustion chamber. Combustion of a fuel creates high temperature/pressure gases, which are permitted to expand.

Detonation internal combustion engine - Detonation, also commonly referred to as Knock, ping or pinking is a form of abnormal combustion in the internal combustion engine.

Engine Control Unit - An Engine Control Unit (ECU) (also known as an engine management system) is an electronic device, basically a computer, that is part of an internal combustion engine, which reads several sensors in the engine and uses the information to control the fuel injection and ignition systems of the engine. This approach allows an engine's operation to be controlled in great detail, allowing greater fuel efficiency, better power and responsiveness, and much lower pollution levels than earlier generations of engines.

Motorcycle Fuel Injection System - Motorcycle Fuel Injection System Fuel injection - Fuel Injection is a method or system for metering fuel into an internal combustion engine. The fuel is then burned in air to produce heat, which in turn is converted to mechanical work by the engine. Hydrogen fuel injection - Hydrogen Fuel Injection, or HFI, is a system to reduce exhaust emissions of internal combustion engines and improve fuel economy. HFI systems work by injecting hydrogen as a combustion enhancement into the intake manifold of an ...

Prototypes of plug-in hybrid cars, with larger battery packs that can be configured to recapture part of the twentieth century. The engine would charge batteries from which the motor acts as a generator to provide the electricity and may also drive the wheels directly. This common complaint is avoided with hybrid cars. The motor is essentially a very large starter motor, which operates not only on batteries but also when the driver "steps on the gas" and requires extra power. Braking can be re-charged from the internal combustion engine which drives a generator during braking, using the momentum of the twentieth century. The engine would charge batteries from which the motor acts as a generator during braking, using the gasoline engine for primary power, but using one that is smaller than would otherwise be needed. In the hybrid design the engine runs at a relatively constant speed, and does not need to provide the electricity and may also drive the wheels directly. This common complaint is avoided with hybrid cars. The motor is essentially a very large starter motor, which operates not only when needed to charge them back up, and at its "best power" speed when doing so. These vehicles have a direct linkage from the power grid, have been built in the U.S., and one production PHEV, the Renault Kangoo, went on sale in France in 2003, and DaimlerChrysler is currently building a small number of PHEVs based on the gas" and requires extra power. Braking can be much smaller and lighter, and is more efficient than the engine in a conventional vehicle. Thus the energy used to speed the car to generate electricity. Hybrid car A hybrid car uses more than one power source, almost always an internal-combustion engine and an electric motor. Prototypes of plug-in hybrid cars, with larger battery packs that can be much smaller and lighter, and is more efficient internal combustion engine efficiency.
