A highly efficient fuel injection system is essential for the clean operation of a diesel engine. HPCR is an advanced fuel injection design that does a better job regulating fuel pressure and injection timing. HPCR is already being used on Bobcat’s high-output engines, and its Engine Control Unit (ECU) technology is instrumental in meeting Stage IIIB and Stage IV requirements.
It allows the application of further technologies such as Diesel Oxidation Catalyst (DOC), Selective Catalytic Reduction (SCR) and Diesel Particulate Filter (DPF) systems, which are described below.
How does HPCR work?
The ECU (Engine Control Unit) controls the injectors precisely to allow multiple fuel injections during each combustion cycle.
The benefits of better combustion
High pressure transforms the fuel into an extremely fine mist as it leaves the injectors. The fuel combusts more thoroughly in this form, leading to:
