A 2-horsepower (1.5 kW) engine, built in 1818 for pumping water at an Ayrshire quarry, continued to work for some time until a careless attendant allowed the heater to overheat. This experiment proved to the inventor that, owing to the low working pressure obtainable, the engine could only be adapted to low power for which there was, at that ...
A planar wideband zirconia sensor (schematic picture) A variation on the zirconia sensor, called the "wideband" sensor, was introduced by NTK in 1992 [5] and has been widely used for car engine management systems in order to meet the ever-increasing demands for better fuel economy, lower emissions and better engine performance at the same time.

It has been stated that the potential energy savings could be higher for gasoline engines rather than for diesel engines. [35] For more details, see the article: Automotive thermoelectric generator. For aircraft, engine nozzles have been identified as the best place to recover energy from, but heat from engine bearings and the temperature ...
The performance of the planar design is currently better than the performance of the tubular design, however, because the planar design has a lower resistance comparatively. Other geometries of SOFCs include modified planar fuel cell designs (MPC or MPSOFC), where a wave-like structure replaces the traditional flat configuration of the planar ...
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

The Standard lists 12 climatic regions and the limits range from −3 °C to 15 °C. Ordinarily, Australian automotive diesel fuels on average have a cold filter plugging point value that is about 2 °C below the cloud point. The Standard also lists particular locations where fuel problems may possibly occur because of cold weather conditions. [10]
Schematic diagram of typical coal-fired power plant steam generator highlighting the air preheater (APH) location. An air preheater is any device designed to heat air before another process (for example, combustion in a boiler), with the primary objective of increasing the thermal efficiency of the process.
The ALCO 244 was a diesel prime mover built by the American Locomotive Company (ALCO). An evolution of the earlier 241 diesel engine, it powered ALCO's first generation of production road locomotives. The 244 engine was developed to create an engine capable of being used in railroad freight and passenger locomotives.
