OIGI® Gas Technologies
The Hardstaff OIGI® (Oil Ignition Gas Injection) is a dual fuel system developed to substitute natural gas for diesel in light and heavy duty engines.
The natural gas injection system is electronically controlled and functions with a sequential operation. It has been developed in conjunction with Loughborough University to provide fully optimised strategies and mixing fields, ensuring accurate delivery of natural gas to the cylinders.
The OIGI® fuel management is a sophisticated system, integrated to give precise control of the gas and diesel injected via accurate timing and metering. The system is also OBD (On Board Diagnostics) compliant.
Diesel is required as the ignition source in dual fuel engines. With the OIGI® system the engine will use 100% diesel at idle; gas injection and diesel reduction commences when engine speed increases from idle. Precise control of diesel reduction and gas injection quantities ensures efficient fuel use and performance equivalent to the original diesel engine.
For the first time, the OIGI® system provides a solution for dual fuel in urban operation conditions, as natural gas is introduced from approximately 620 rpm; giving reduced emissions levels with the benefits of diesel engine performance and economy.
The OIGI® system natural gas injectors can be used in various applications using several injection methods, incorporating Hardstaff's custom injector blocks. They operate on a linear basis giving optimum efficiency and, due to their low pressure operation, can ensure highly accurate gas quantities are injected, enabling the system to meet tight emission controls.
The injectors are certified to the European Standard ECE R110 and unlike other injectors currently available, the OIGI® injectors are extremely durable and robust. They are low maintenance with a proven performance and reliability record, requiring minimal servicing.
