The Green City Start-up is an initiative by the City of Johannesburg in collaboration with the University of Johannesburg. The aim is to give innovative entrepreneurs an opportunity to have their ideas developed into Green City Start-ups.

The 2016 winner was Ducere Holdings (PTY) LTD. Their proposal promotes liquid fuel savings; effectively capturing and storing the “momentum energy of the moving vehicle”, the kinetic energy and regenerative braking, and then using the stored energy, smartly and automatically, on re-acceleration. This is an added modification promoted for both new and existing vehicles. The net result is direct savings on liquid fuels consumed over a journey.

MISER is a new, hydraulic version of hybrid transmission for vehicles that costs less and is more efficient. MISER offers fuel savings of up to 70%. A fully automatic transmission, it achieves significantly reduced emissions. It is ideal for new vehicle designs but can also be fitted to existing vehicles. MISER covers a wide range of vehicles ranging from passenger vehicles to long distance trucks and large earth moving equipment; including electric hybrids. MISER allows the vehicle to store and reuse kinetic energy which is usually lost as vehicles stop and start. It also allows for engine optimisation and fuel efficiency.

2017: Academic and Post Graduate Development (Part 1 of a series of Associated Efforts)

The project now moves deep into the laboratory phase. The University has invited the Green City Start-up to promote their own employees to pursue post graduate study. This is a first pass call for continued research and development of their start-up idea and initial commercial solution towards a sustainable and mature technology for greater application.

Two postgraduate (Masters) students are promoted by MISER. Their first academic presentation (initial research proposal) is set for April 26 th; Mechanical Engineering Research Forum, School of Mechanical and Industrial Engineering Science, APK University of Johannesburg. The Joint Supervision for the research study will be undertaken by both the Departments of Mechanical Engineering Technology (DFC) and Mechanical Engineering Science (APK), in association with the City of Johannesburg.

All the work planned will be defined and captured in the FEBE KPI Contracts for 2017, 2018 and 2019; including:

Papers to be published: Identified Journal, Timing, Authors

Papers to be presented: Identified Conference, Timing, Authors

Patents to be applied for: Timing, Accountability

CPD SLP: Timing, Accountability, Accreditation

In addition, the project is positioned to be of focus for the workings of the UJ SAIMechE Student Chapters of DFC and APK; for industry liaison, field visits and in service work integrated learning and professional development.

Presenter 1: Donovan Leslie Wressell: Mechanical Engineering Technologist



Don Wressell is a design engineer at Turnkey Hydraulics.

Topic of Presentation: Research and development of the MISER hydraulic system, the development of the world first open loop over centre hydraulic pump/motor for use on the Miser Hydraulic Hybrid vehicle. Don plans to fine tune his design to improve total efficiency and ultimately fuel and emission savings.

 

Presenter 2: Norman Grant: Chief Mechanical Engineer



Norman Grant is an engineer at Ducere Holdings (Pty) Ltd. He has a wide Industry background and is the original inventor and head designer of the novel “Miser” range of Hydraulic Hybrid Transmissions that can be used in many applications, not only vehicles.

Topic of Presentation : Brief introduction of the “Miser Hydraulic hybrid transmission” for both internal combustion engines and electric vehicles. The system has the ability to save significant fuel AND improve vehicle performance by using Regenerative Braking and Engine Optimization
