The requirements on systematic reduction of the fuel consumption by compression ignition engines and the raising of reliability and service life by pump exploitation, ecological requirements on air pollution reducing together with requirements on combustion of less valuable fuels and other oil products claim qualitive higher fuel injection.

The requirements for systematic reduction of fuel consumption by compression ignition engines and raising the reliability and service life by pump exploitation, ecological requirements for reducing air pollution together with requirements for combustion of less valuable fuels and other oil products demand a qualitative higher fuel injection.

That is why Motorpal has developed single cylinder pumps in form „m“- the last technical degree in this field. These are monoblock fuel injection pumps. By these pumps there is an almost closed cylinder in the upper part which helps to enhance its rigidity, to reduce the deformation caused by high injection pressures and thus to prevent fuel leakage around the piston and cylinder during fuel injection. Toward the injection pressure one sealing surface is exposed only, so that the danger of looseness in the high pressure part is reduced to a minimum. All injection pumps are provided with constant-pressure delivery valves and pistons with variable lead of helix. The delivery fuel quantity depends on the piston position, and on the injection beginning as well. This is a way to reduce air pollution and to meet current and future ecological regulations.

The piston and cylinder can be lubricated with fi ne pressure oil. The leaking fuel is fed out of the injection pump area. The construction of these pumps enables the exploitation of heavy oils and injection pressures of 150 MPa to be reached.
