Injection pump for a 12-cylinder diesel engine. An injection pump is the device that pumps fuel into the cylinders of a diesel engine. Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft. It rotates at half crankshaft speed in a ...

Yanmar manufactures and sells engines used in a wide range of applications, including seagoing vessels, pleasure boats, construction equipment, agricultural ...
Diesel engines can combust a large variety of fuels, including many sorts of oil, petrol, [4] and combustible gases. [5] This means that if there is any type of leak or malfunction that increases the amount of oil or fuel unintentionally entering the combustion chamber, the quality of the air-fuel-mixture will increase, causing torque and ...
EDC injection inline pump. 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 ...
[citation needed] An example is a diesel engine powering equipment at an oil well head. Suppose the operators hit a pocket of natural gas. Suppose the operators hit a pocket of natural gas. In that case, it will come to the surface and the engine will take in the flammable gas and rapidly increase speed until the engine is destroyed, unless the ...
The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the unit Injector system, and is designed for use in commercial vehicle diesel engines. [ 2 ] The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in the block ...
An electric starter with sufficient power to turn a large diesel engine would itself be so large as to be impractical so there is a need for an alternative system. An air start system has three main components along with various safety components, namely the air start injector, the distributor and the air receivers.
