In 1993, Caterpillar designed an electronically controlled pump-injector unit with hydraulic gear, which became one of the most important contributions to the development of the diesel combustion engine in a hundred years. The unique high-pressure electronic fuel injection system Cat HEUI brings the following advantages:

• It improves the performance of the fuel supply system;
• It solves some problems related to mechanical injectors;
• It eliminates the dependence on the crankshaft rotation frequency.

The wonderful performance characteristics of the components of the Cat fuel supply system are due to the use of special metals and patented technologies in their productions. Besides, Caterpillar fuel system components undergo a series of tests and they are calibrated in accordance with the specific technical requirements.
