The efficiency of an engine is defined as ratio of the useful work done to the heat provided. where, is the heat absorbed and is the work done. Please note that the term work done relates to the power delivered at the clutch or at the driveshaft . This means the friction and other losses are subtracted from the work done by thermodynamic expansion.
Diesel engine built by Langen & Wolf under licence, 1898 1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition ...
A Cylinder Head Temperature gauge (CHT) measures the cylinder head temperature of an engine. Commonly used on air-cooled engines, the head temperature gauge displays the work that the engine is performing more quickly than an oil or water temperature gauge. As the engine works at high speed or uphill, head temperature will increase quickly.
Electronic fuel control, DPF and EGR. The Cummins B Series is a family of diesel engines produced by American manufacturer Cummins. In production since 1984, the B series engine family is intended for multiple applications on and off-highway, light-duty, and medium-duty. In the automotive industry, it is best known for its use in school buses ...
It is a family of 3-cylinder and 4-cylinder diesel engines featuring modular diesel engine system (MDB (Modularer Diesel Motor Baukasten)), with dual-loop EGR system, with high pressure EGR and a cooled low-pressure EGR loops; variable valve train (VVT) with a camshaft adjuster, Bosch CRS 2-20 2000 bar common rail injection system, cylinder ...
The Navistar DT (Diesel Turbocharged or Diesel Turbo) engine family is a line of mid-range inline-6 diesel engines.With horsepower ratings ranging from 170 hp (130 kW) to 350 hp (260 kW), the Navistar DT engines are used primarily in medium-duty truck and bus applications such as school buses, although some versions have been developed for heavy-duty regional-haul and severe-service applications.
The Detroit Diesel Series 71 is a two-stroke diesel engine series, available in both inline and V configurations, manufactured by Detroit Diesel. The number 71 refers to the nominal displacement per cylinder in cubic inches, a rounding off of 70.93 cu in (1.2 L). Inline models included one, two, three, four and six cylinders, and the V-types ...
An internal combustion engine ( ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high- temperature and high- pressure gases produced by combustion ...
