The Wärtsilä 31 is setting a new standard for energy efficiency, delivering the lowest level of fuel consumption of any four-stroke engine worldwide. It also offers an unprecedented level of operational flexibility and can easily be adapted to accommodate different fuel types and operating profiles.

FUNDAMENTALS OF GAS TURBINE ENGINES INTRODUCTION The gas turbine is an internal combustion engine that uses air as the working fluid. The engine extracts chemical energy from fuel and converts it to mechanical energy using the gaseous energy of the working fluid (air) to drive the engine and propeller, which, in turn, propel the airplane.

Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There are two classifications of thermal engines- Internal combustion and External combustion engines.

Each of these engines has thermal efficiency characteristics that are unique to it. Engine efficiency, transmission design, and tire design all contribute to a vehicle's fuel efficiency.

As heat recovery can be quite efficient for smaller systems, these systems are more popular with smaller energy consuming facilities, particularly those having a greater need for electricity than thermal energy and where the quality of heat required is not high, e.g.

The Energy Efficient Engine was a program funded by NASA in the s to develop technologies suitable for energy efficient turbofans, its goal was to improve thrust specific fuel consumption by 12% compared to a GE CF6 C.

Energy efficiency of the converters. Increasing of the energy efficiency of the convertors can be achieved by optimizing their configuration and control, as well as choosing the adequate component. Converter configuration depends on the type of the electric motor (DC or AC), possible recovery energy braking, drive dynamics by: 4.

An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines, like the internal combustion engine, burn a fuel to create heat which is then used to do work.

Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air, and clockwork motors in wind-up toys use elastic energy. The item Energy efficient engine: integrated core/low spool design and performance report, by Aircraft Engine Business Group, Advanced Technology Programs Dept represents a specific, individual, material embodiment of a distinct intellectual or artistic creation found in Indiana State Library.

The high pressure turbine configuration for the Energy Efficient Engine is built around a two-stage design system. Moderate aerodynamic loading for both stages is used to achieve the high level of turbine efficiency. The Energy Efficiency Manual shows how to save energy and conserve water in all types of buildings, industrial facilities, and homes – from the smallest to the largest.

This book pays for itself the first time you use it. superbly explained energy conservation measures optimize energy usage in every part of your building or facility. Steam engines should be considered as an alternative to internal combustion engines in the power range above about kW if biomass is the preferred fuel.

From: Renewable Energy Technologies, Related terms. Fuel efficiency is a form of thermal efficiency, meaning the ratio from effort to result of a process that converts chemical potential energy contained in a carrier into kinetic energy or l fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile.
