A fire pump can be driven by an electric motor, diesel engine or steam drive. While electric motors are most common, steam drives are infrequently utilized. Diesel engines are often used when the electrical supply to the property is unreliable or has insufficient capacity. They also are used by clients who desire a primary electric motor-driven
Diesel exhaust fluid, or DEF, is a solution of deionized water and urea. It eliminates noxious nitrogen oxides from diesel engine exhausts. Our editors and experts handpick every product we feature. We may earn a commission from your purchases. It wasn’t that long ago when people reviled cars, trucks and buses with diesel engines for their
A tractor works with a PTO (power take-off). It uses a grooves attachment point when attached to a PTO driven Implement to spin the shaft to a set rate. Also, tractor engines are powered by diesel and have a transmission system, including mostly 8-speed or 10-speed gearbox for transmitting the power to work.
In diesel engines, fuel is injected during the compression stroke before the piston reaches top dead centre (TDC). Only the air is compressed on the compression stroke which causes it to become hot enough to ignite the fuel. In a mechanical system, the fuel charge is accurately metered and pressurised by the fuel injection pump and passed to
An EGR is a valve within a diesel engine that’s used to control the volume of nitrogen oxide (NOx) emissions released through the exhaust. NOx is among the most toxic emissions produced during the diesel combustion cycle, so it’s critical to reduce its occurrence in exhaust fumes by as great a margin as possible. This isn’t always possible or economically viable, however, which is why diesel electric trains also exist. Where power lines aren’t a possibility, generating power for the electric motors using a diesel engine is particularly efficient, providing a host of advantages that solutions such as batteries can’t match. The concept of biofuels is surprisingly old. Rudolf Diesel, whose invention now bears his name, had envisioned vegetable oil as a fuel source for his engine. In fact, much of his early work revolved around the use of biofuel. In 1900, for example, at the World Exhibition in Paris, France, Diesel demonstrated his engine by running it on peanut
The engine emits these particulates mainly in the form of carbon or soot. You can find this type of carbon particulates mostly in the vehicles that operate on diesel engines. Because of the high compression ratio of the diesel engine, the exhaust coming out from the diesel engines contains the carbon particulates with high density and of bigger

The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption. These demands are now primarily fulfilled by
