The factory-developed and warranted sequential multi-port gaseous electronic injection system will be available for the fifth generation HiAce, a ‘one box’ design for Asia-Pacific and Far and Middle East markets that differs from the ‘bonnet van’ Hiace sold in Europe.
Toyota’s manager, new business development, product development division, Robert Allen said the system has been developed with an eye to the future (Euro IV) emission requirements for Australia.
“The sequential multi-port gaseous injection system has significant advantages over fumigation-type LPG systems – including no backfire,” he said.
“There is no loss of volumetric efficiency and no restriction on inlet airflow.
“The results from over 150,000 kilometres of local testing suggest there is no noticeable difference in on-road performance between petrol and LPG operation using this system.”
Toyota has developed the dual-fuel system in Australia to suit the redesigned HiAce’s all-new VVT-I-equipped 2.7-litre engine.
All petrol models in the new range will have hardened valves and valve seats, to allow for LPG operation.
Toyota Australia’s product development division has developed the Landi Renzo Omegas system with local supplier Apollo Gas Products.
The system has full electronic control for optimum reliability and fuel efficiency, and plug ‘n’ play wiring for ease of installation and reliability.
The conversion includes an under-floor twin tank system with a protective shield. The spare wheel is relocated inside the vehicle.
The system uses the original fuel gauge for both petrol and LPG.
It provides for petrol start and switches automatically to gas, depending on engine temperature and vehicle operating conditions.
LPG is a popular alternative fuel in Australia. Visitors are likely to experience a drive in an LPG-fuelled car when they take a taxi from the airport.
