Eco-Friendly Technology that has a positive influence on the environment

G-Cylinder Pty Ltd is an environmentally responsible company with strong ethical foundation for sustainable human development.


Less Fossil Fuels Used

Fuel consumption is a relevant topic on a world stage, with limited fossil fuels available , the process consuming hydrocarbons must improve to limit waste. ‘The high volume demand for fuel partially decreases using G-Cylinder.

Increasing Fuel Economy makes the most of the world’s limited resources of fossil fuels.


Cleaner Emissions

Up to 60% Exhaust Hydrocarbons are utilized in combustion, resulting in a cleaning operating engine.

In today’s resource competitive world, G-Cylinder aims to provide a means to engage in sustainable commerce for local businesses, Governments and operators in the International community by utilizing our oil resources more efficiently and reducing the impacts of toxic atmospheric emissions.


Reduction of Waste

G-Cylinder – proven to be effective in reducing toxic green house emissions such as carbon and nitrogen oxides

This technology works on your existing engine, and prolongs the lifetime of the machine, therefore maximizing your current machinery and minimizing waste.

¼ throttle tests with the G-cylinder show a noticeable decrease in specific fuel consumption.

December 10th 2004.

1966 Holden 161 “red” engine, 2,640cc

Test 4: 0.456 kg/kWh ¼ throttle, with G-cylinder

Test 5: 0.549 kg/kWh ¼ throttle, no G-cylinder

Download the Data

The results from test 4 (¼ throttle with the g-cylinder) gave a 17% reduction in specific fuel consumption in comparison to test 5 (¼ throttle no g-cylinder)

The tests conducted at UWA show the G-cylinder achieving 17% improved fuel consumption. The short 15 minute tests do not conclusively evaluate the G-cylinder. Results indicate and reinforce that this could be the worlds most advanced superior fuel saving device.
