Making a Hybrid even cleaner! LPG
14 Attachment(s)
In the UK converting Petrol engines to LPG is a very common way to save on running cost and reduce engine emissions. As most Hybrids run on Petrol it is possible to do the same but there are some added complications with the stop start of the petrol engine.
We have converted a number of the Toyota Prius range. I was recently aproached by a customer wanting to convert a Hybrid Toyota Estima. Fortunately we had solved all the technical issues with the Prius conversions and all went smoothly with this one. The Hybrid engine presents a couple of issues where the engine switches on and off changing from electric to petrol. For best emissions and fuel consumption a modern OBD compliant electronic piggy back LPG injection system must be used. The down side with this type of system is that they usually have to run for some 30 seconds on petrol each time the starts before automatically changing over to LPG running. With some software modifications we have been able to build a system that does the first start on Petrol and then once the engine has warmed enough for the lambda sensor to be functional then switches over to LPG. Each subsequent start is then made on LPG to minimise petrol use. To make this work correctly a permanent ignition live must be used rather than an engine ignition live as used in typical conversions.

Re: Making a Hybrid even cleaner! LPG
The Honda is very much the same as the Toyota to convert, the technical issues are the same with the same solutions.
