Fuel priming pump (fig. 1). Piston type, mounted on high pressure pump and driven by camshaft eccentric

The power and economic performance of the engine, as well as the reliability of its operation, largely depend on the thoroughness and quality of the adjustment of the parameters of the high-pressure fuel pump
