Fuel Handling System for Gas Conversion - Sisu Diesel 420 DWRIE

Guijarro Fernandez, Ruben; Sancho Naval, David (2021)

Avaa tiedosto
This thesis was commissioned by Novia University of Applied Sciences. The aim of the thesis was to design a fuel gas handling system for operating on fuel gas in the engine laboratory of Novia to convert a diesel engine to a gas-fuelled engine. The engine is a SISU Diesel 420 DWRIE, this conversion could also be applied to a diesel power vehicle. To do this, a theoretical study of the most suitable fuel gas for engine conversion has been conducted. CNG was determined to be the most feasible fuel gas for this case, in terms of space, fuel availability, price, safety aspects and impact on the environment. A review has also been made of the fuel system of diesel engines and the adaptations that would have to be made to run on natural gas. By analysing different existing models are all the necessary components for the conversion of the whole fuel system have been determined, costed, and documented. The final part consists of the calculations of the installation and the proposal of a possible design, as a piping and instrumentation diagram. The findings of the thesis are the design of a fuel management system for compressed natural gas operation adapted to the conversion of the Sisu engine. This work is complemented by another project in which specific modifications are made to the engine. It also provides a basis for future work in which to continue with the engine conversion, simulating and subsequently building the design of the present thesis. (2.736Mt)
