The Daihatsu DK20 is a type of marine diesel engine produced by Daihatsu Diesel Mfg. Co., Ltd. Fuel pumps for Daihatsu DK20 are the components responsible for delivering fuel from the fuel tank to the engine's combustion chamber.
There are two main types of fuel pumps used in diesel engines: mechanical and electric. The Daihatsu DK20 engine typically uses a mechanical fuel pump, which is driven by a camshaft and is typically mounted on the engine block.
The mechanical fuel pump for the Daihatsu DK20 typically consists of a fuel pump body, a plunger, a cam follower, and a spring. As the camshaft rotates, it pushes the cam follower, which in turn pushes the plunger. This creates a low-pressure area, which draws fuel into the fuel pump body through an inlet valve. The plunger then pushes the fuel out through an outlet valve and into the engine's fuel injection system.
The fuel pump is a critical component of the engine's fuel system, and any issues with the fuel pump can lead to poor engine performance or failure. It's important to ensure that the fuel pump is properly maintained and that any worn or damaged components are replaced as needed.
If you need to purchase fuel pumps for a Daihatsu DK20 engine, you can check with authorized Daihatsu dealers or distributors, as well as with independent suppliers who specialize in providing diesel engine parts.
